Jeep Grand Cherokee (2019 year). Instruction

NOTE:

When filling warm tires, the tire pressure may need

to be increased up to an additional 4 psi (28 kPa) above the
recommended cold placard pressure in order to turn the
TPMS Warning Light off.

The system will automatically update, the graphic display
of the pressure value(s) will return to its original color and
the TPMS Warning Light will extinguish once the updated
tire pressure(s) have been received. The vehicle may need
to be driven for up to 20 minutes above 15 mph (24 km/h)
to receive this information.

Service TPM System Warning

The Tire Pressure Monitoring System Warning Light will
flash on and off for 75 seconds, and remain on solid when
a system fault is detected. The system fault will also sound
a chime. The instrument cluster display will display a
“SERVICE TPM SYSTEM” message for a minimum of five
seconds. This message is then followed by a graphic
display, with “- -“ in place of the pressure value(s),
indicating which Tire Pressure Monitoring Sensor(s) is not
being received.

If the ignition switch is cycled, this sequence will repeat,
providing the system fault still exists. If the system fault no
longer exists, the Tire Pressure Monitoring System Warning
Light will no longer flash, the

⬙SERVICE TPM SYSTEM⬙

message will not be present, and a pressure value will be
displayed instead of dashes. A system fault can occur by
any of the following:
• Jamming due to electronic devices or driving next to

facilities emitting the same Radio Frequencies as the
TPM sensors.

• Lots of snow or ice around the wheels or wheel hous-

ings.

• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.

196

SAFETY

NOTE:

There is no tire pressure monitoring sensor in the

spare tire. The TPMS will not be able to monitor the tire
pressure. If you install the spare tire in place of a road tire
that has a pressure below the low-pressure warning limit,
upon the next ignition switch cycle, the Tire Pressure
Monitoring System Warning Light will remain on, a chime
will sound, and the instrument cluster display will still
display a pressure value in the different color graphic
display and an “Inflate to XX” message will be displayed.
After driving the vehicle for up to 20 minutes above
15 mph (24 km/h), the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and then
remain on solid. In addition, the instrument cluster display
will display a “SERVICE TPM SYSTEM

⬙ message for five

seconds and then display dashes (- -) in place of the
pressure value. For each subsequent ignition switch cycle,
a chime will sound, the Tire Pressure Monitoring System
Warning Light will flash on and off for 75 seconds and then
remain on solid, and the instrument cluster display will
display a

⬙SERVICE TPM SYSTEM⬙ message for five sec-

onds and then display dashes (- -) in place of the pressure
value. Once you repair or replace the original road tire, and
reinstall it on the vehicle in place of the spare tire, the
TPMS will update automatically.

In addition, the Tire Pressure Monitoring System Warning
Light will turn off and the graphic in the instrument cluster
display will display a new pressure value instead of dashes
(- -), as long as no tire pressure is below the low-pressure
warning limit in any of the four active road tires. The
vehicle may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.

TPMS Deactivation — If Equipped

The Tire Pressure Monitoring System (TPMS) can be deac-
tivated if replacing all four wheel and tire assemblies (road
tires) with wheel and tire assemblies that do not have
TPMS Sensors, such as when installing winter wheel and
tire assemblies on your vehicle.

To deactivate the TPMS, first, replace all four wheel and
tire assemblies (road tires) with tires not equipped with
Tire Pressure Monitoring (TPM) Sensors. Then, drive the
vehicle for 20 minutes above 15 mph (24 km/h). The TPMS
will chime, the TPMS Warning Light will flash on and off
for 75 seconds and then remain on. The instrument cluster
will display the “SERVICE TPM SYSTEM” message and
then display dashes (--) in place of the pressure values.

SAFETY

197

Beginning with the next ignition cycle, the TPMS will no
longer chime or display the “SERVICE TPM SYSTEM”
message in the instrument cluster but dashes (--) will
remain in place of the pressure values.

To reactivate the TPMS, replace all four wheel and tire
assemblies (road tires) with tires equipped with TPM
sensors. Then, drive the vehicle for up to 20 minutes above
15 mph (24 km/h). The TPMS will chime, the TPMS
Warning Light will flash on and off for 75 seconds and then
turn off. The instrument cluster will display the “SERVICE
TPM SYSTEM” message and then display pressure values
in place of the dashes. On the next ignition cycle the

⬙SERVICE TPM SYSTEM⬙ message will no longer be dis-
played as long as no system fault exists.

OCCUPANT RESTRAINT SYSTEMS

Some of the most important safety features in your vehicle
are the restraint systems:

Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air Bags
• Supplemental Active Head Restraints
• Child Restraints
Some of the safety features described in this section may be
standard equipment on some models, or may be optional
equipment on others. If you are not sure, ask an authorized
dealer.

Important Safety Precautions

Please pay close attention to the information in this section.
It tells you how to use your restraint system properly, to
keep you and your passengers as safe as possible.

198

SAFETY

Here are some simple steps you can take to minimize the
risk of harm from a deploying air bag:

1. Children 12 years old and under should always ride

buckled up in the rear seat of a vehicle with a rear seat.

2. A child who is not big enough to wear the vehicle seat

belt properly (Refer to “Child Restraints” in this section
for further information) must be secured in the appro-
priate child restraint or belt-positioning booster seat in a
rear seating position.

3. If a child from 2 to 12 years old (not in a rear-facing child

restraint) must ride in the front passenger seat, move the
seat as far back as possible and use the proper child
restraint (Refer to “Child Restraints” in this section for
further information).

4. Never allow children to slide the shoulder belt behind

them or under their arm.

5. You should read the instructions provided with your

child restraint to make sure that you are using it
properly.

6. All occupants should always wear their lap and shoul-

der belts properly.

7. The driver and front passenger seats should be moved

back as far as practical to allow the front air bags room
to inflate.

8. Do not lean against the door or window. If your vehicle

has side air bags, and deployment occurs, the side air
bags will inflate forcefully into the space between occu-
pants and the door and occupants could be injured.

9. If the air bag system in this vehicle needs to be modified

to accommodate a disabled person, refer to the “Cus-
tomer Assistance” section for customer service contact
information.

WARNING!

• Never place a rear-facing child restraint in front of an

air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.

• Never install a rear-facing child restraint in the front

seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.

SAFETY

Seat Belt Systems

Buckle up even though you are an excellent driver, even on
short trips. Someone on the road may be a poor driver and
could cause a collision that includes you. This can happen
far away from home or on your own street.

Research has shown that seat belts save lives, and they can
reduce the seriousness of injuries in a collision. Some of the
worst injuries happen when people are thrown from the
vehicle. Seat belts reduce the possibility of ejection and the
risk of injury caused by striking the inside of the vehicle.
Everyone in a motor vehicle should be belted at all times.

Enhanced Seat Belt Use Reminder System (BeltAlert)

Driver and Passenger BeltAlert (if equipped)

BeltAlert is a feature intended to remind the driver

and outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) to buckle their
seat belts. The Belt Alert feature is active whenever the
ignition switch is in the START or ON/RUN position.

Initial Indication

If the driver is unbuckled when the ignition switch is first
in the START or ON/RUN position, a chime will signal for

a few seconds. If the driver or outboard front seat passen-
ger (if equipped with outboard front passenger seat
BeltAlert) is unbuckled when the ignition switch is first in
the START or ON/RUN position the Seat Belt Reminder
Light will turn on and remain on until both outboard front
seat belts are buckled. The outboard front passenger seat
BeltAlert is not active when an outboard front passenger
seat is unoccupied.

BeltAlert Warning Sequence

The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range
and the driver or outboard front seat passenger is unbuck-
led (if equipped with outboard front passenger seat
BeltAlert) (the outboard front passenger seat BeltAlert is
not active when the outboard front passenger seat is
unoccupied). The BeltAlert warning sequence starts by
blinking the Seat Belt Reminder Light and sounding an
intermittent chime. Once the BeltAlert warning sequence
has completed, the Seat Belt Reminder Light will remain on
until the seat belts are buckled. The BeltAlert warning
sequence may repeat based on vehicle speed until the
driver and occupied outboard front seat passenger seat
belts are buckled. The driver should instruct all occupants
to buckle their seat belts.

200

SAFETY

Change of Status

If the driver or outboard front seat passenger (if equipped
with outboard front passenger seat BeltAlert) unbuckles
their seat belt while the vehicle is traveling, the BeltAlert
warning sequence will begin until the seat belts are buck-
led again.

The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other items
are placed on the outboard front passenger seat or when
the seat is folded flat (if equipped). It is recommended that
pets be restrained in the rear seat (if equipped) in pet
harnesses or pet carriers that are secured by seat belts, and
cargo is properly stowed.

BeltAlert can be activated or deactivated by an authorized
dealer. FCA US LLC does not recommend deactivating
BeltAlert.

NOTE:

If BeltAlert has been deactivated and the driver or

outboard front seat passenger (if equipped with outboard
front passenger seat BeltAlert) is unbuckled the Seat Belt
Reminder Light will turn on and remain on until the driver
and outboard front seat passenger seat belts are buckled.

Lap/Shoulder Belts

All seating positions in your vehicle are equipped with
lap/shoulder belts.

The seat belt webbing retractor will lock only during very
sudden stops or collisions. This feature allows the shoulder
part of the seat belt to move freely with you under normal
conditions. However, in a collision the seat belt will lock
and reduce your risk of striking the inside of the vehicle or
being thrown out of the vehicle.

WARNING!

• Relying on the air bags alone could lead to more

severe injuries in a collision. The air bags work with
your seat belt to restrain you properly. In some
collisions, the air bags won’t deploy at all. Always
wear your seat belt even though you have air bags.

• In a collision, you and your passengers can suffer

much greater injuries if you are not properly buckled
up. You can strike the interior of your vehicle or
other passengers, or you can be thrown out of the
vehicle. Always be sure you and others in your
vehicle are buckled up properly.

SAFETY

201

WARNING! (Continued)

• It is dangerous to ride in a cargo area, inside or

outside of a vehicle. In a collision, people riding in
these areas are more likely to be seriously injured or
killed.

• Do not allow people to ride in any area of your

vehicle that is not equipped with seats and seat belts.

• Be sure everyone in your vehicle is in a seat and

using a seat belt properly. Occupants, including the
driver, should always wear their seat belts whether
or not an air bag is also provided at their seating
position to minimize the risk of severe injury or
death in the event of a crash.

• Wearing your seat belt incorrectly could make your

injuries in a collision much worse. You might suffer
internal injuries, or you could even slide out of the
seat belt. Follow these instructions to wear your seat
belt safely and to keep your passengers safe, too.

• Two people should never be belted into a single seat

belt. People belted together can crash into one an-
other in a collision, hurting one another badly. Never
use a lap/shoulder belt or a lap belt for more than one
person, no matter what their size.

WARNING!

• A lap belt worn too high can increase the risk of

injury in a collision. The seat belt forces won’t be at
the strong hip and pelvic bones, but across your
abdomen. Always wear the lap part of your seat belt
as low as possible and keep it snug.

• A twisted seat belt may not protect you properly. In

a collision, it could even cut into you. Be sure the seat
belt is flat against your body, without twists. If you
can’t straighten a seat belt in your vehicle, take it to
an authorized dealer immediately and have it fixed.

• A seat belt that is buckled into the wrong buckle will

not protect you properly. The lap portion could ride
too high on your body, possibly causing internal
injuries. Always buckle your seat belt into the
buckle nearest you.

• A seat belt that is too loose will not protect you

properly. In a sudden stop, you could move too far
forward, increasing the possibility of injury. Wear
your seat belt snugly.

(Continued)

202

SAFETY

WARNING! (Continued)

• A seat belt that is worn under your arm is dangerous.

Your body could strike the inside surfaces of the
vehicle in a collision, increasing head and neck
injury. A seat belt worn under the arm can cause
internal injuries. Ribs aren’t as strong as shoulder
bones. Wear the seat belt over your shoulder so that
your strongest bones will take the force in a collision.

• A shoulder belt placed behind you will not protect

you from injury during a collision. You are more
likely to hit your head in a collision if you do not
wear your shoulder belt. The lap and shoulder belt
are meant to be used together.

• A frayed or torn seat belt could rip apart in a collision

and leave you with no protection. Inspect the seat
belt system periodically, checking for cuts, frays, or
loose parts. Damaged parts must be replaced imme-
diately. Do not disassemble or modify the seat belt
system. Seat belt assemblies must be replaced after a
collision.

Lap/Shoulder Belt Operating Instructions

1. Enter the vehicle and close the door. Sit back and adjust

the seat.

2. The seat belt latch plate is above the back of the front

seat, and next to your arm in the rear seat (for vehicles
equipped with a rear seat). Grasp the latch plate and
pull out the seat belt. Slide the latch plate up the
webbing as far as necessary to allow the seat belt to go
around your lap.

Pulling Out The Latch Plate

SAFETY

203

3. When the seat belt is long enough to fit, insert the latch

plate into the buckle until you hear a “click.”

4. Position the lap belt so that it is snug and lies low across

your hips, below your abdomen. To remove slack in the
lap belt portion, pull up on the shoulder belt. To loosen
the lap belt if it is too tight, tilt the latch plate and pull
on the lap belt. A snug seat belt reduces the risk of
sliding under the seat belt in a collision.

5. Position the shoulder belt across the shoulder and chest

with minimal, if any slack so that it is comfortable and
not resting on your neck. The retractor will withdraw
any slack in the shoulder belt.

SAFETY

6. To release the seat belt, push the red button on the

buckle. The seat belt will automatically retract to its
stowed position. If necessary, slide the latch plate down
the webbing to allow the seat belt to retract fully.

Lap/Shoulder Belt Untwisting Procedure

Use the following procedure to untwist a twisted lap/
shoulder belt.

1. Position the latch plate as close as possible to the anchor

point.

2. At about 6 to 12 inches (15 to 30 cm) above the latch

plate, grasp and twist the seat belt webbing 180 degrees
to create a fold that begins immediately above the latch
plate.

3. Slide the latch plate upward over the folded webbing.

The folded webbing must enter the slot at the top of the
latch plate.

4. Continue to slide the latch plate up until it clears the

folded webbing and the seat belt is no longer twisted.

Adjustable Upper Shoulder Belt Anchorage

In the driver and outboard front passenger seats, the top of
the shoulder belt can be adjusted upward or downward to
position the seat belt away from your neck. Push or
squeeze the anchorage button to release the anchorage, and
move it up or down to the position that serves you best.

As a guide, if you are shorter than average, you will prefer
the shoulder belt anchorage in a lower position, and if you
are taller than average, you will prefer the shoulder belt
anchorage in a higher position. After you release the
anchorage button, try to move it up or down to make sure
that it is locked in position.

Adjustable Anchorage

SAFETY

205

NOTE:

The adjustable upper shoulder belt anchorage is

equipped with an Easy Up feature. This feature allows the
shoulder belt anchorage to be adjusted in the upward
position without pushing or squeezing the release button.
To verify the shoulder belt anchorage is latched, pull
downward on the shoulder belt anchorage until it is locked
into position.

WARNING!

• Wearing your seat belt incorrectly could make your

• Position the shoulder belt across the shoulder and

chest with minimal, if any slack so that it is comfort-
able and not resting on your neck. The retractor will
withdraw any slack in the shoulder belt.

• Misadjustment of the seat belt could reduce the

effectiveness of the safety belt in a crash.

• Always make all seat belt height adjustments when

the vehicle is stationary.

Seat Belt Extender

If a seat belt is not long enough to fit properly, even when
the webbing is fully extended and the adjustable upper
shoulder belt anchorage (if equipped) is in its lowest
position, an authorized dealer can provide you with a Seat
Belt Extender. The Seat Belt Extender should be used only
if the existing seat belt is not long enough. When the Seat
Belt Extender is not required for a different occupant, it
must be removed.

WARNING!

• ONLY use a Seat Belt Extender if it is physically

required in order to properly fit the original seat belt
system. DO NOT USE the Seat Belt Extender if,
when worn, the distance between the front edge of
the Seat Belt Extender buckle and the center of the
occupant’s body is LESS than 6 inches.

• Using a Seat Belt Extender when not needed can

increase the risk of serious injury or death in a
collision. Only use the Seat Belt Extender when the
lap belt is not long enough and only use in the
recommended seating positions. Remove and store
the Seat Belt Extender when not needed.

206

SAFETY

Seat Belts And Pregnant Women

Seat belts must be worn by all occupants including preg-
nant women: the risk of injury in the event of an accident
is reduced for the mother and the unborn child if they are
wearing a seat belt.

Position the lap belt snug and low below the abdomen and
across the strong bones of the hips. Place the shoulder belt
across the chest and away from the neck. Never place the
shoulder belt behind the back or under the arm.

Seat Belt Pretensioner

The front outboard seat belt system is equipped with
pretensioning devices that are designed to remove slack
from the seat belt in the event of a collision. These devices
may improve the performance of the seat belt by removing
slack from the seat belt early in a collision. Pretensioners
work for all size occupants, including those in child
restraints.

NOTE:

These devices are not a substitute for proper seat

belt placement by the occupant. The seat belt still must be
worn snugly and positioned properly.

The pretensioners are triggered by the Occupant Restraint
Controller (ORC). Like the air bags, the pretensioners are
single use items. A deployed pretensioner or a deployed air
bag must be replaced immediately.

Energy Management Feature

The front outboard seat belt system is equipped with an
Energy Management feature that may help further reduce
the risk of injury in the event of a collision. The seat belt
system has a retractor assembly that is designed to release
webbing in a controlled manner.

Switchable Automatic Locking Retractor (ALR)

The seat belts in the passenger seating positions are
equipped with a Switchable Automatic Locking Retractor
(ALR) which is used to secure a child restraint system. For
additional information, refer to “Installing Child Restraints
Using The Vehicle Seat Belt” under the “Child Restraints”
section of this manual. The figure below illustrates the
locking feature for each seating position.

If the passenger seating position is equipped with an ALR
and is being used for normal usage, only pull the seat belt
webbing out far enough to comfortably wrap around the
occupant’s mid-section so as to not activate the ALR. If the
ALR is activated, you will hear a clicking sound as the seat
belt retracts. Allow the webbing to retract completely in
this case and then carefully pull out only the amount of
webbing necessary to comfortably wrap around the occu-
pant’s mid-section. Slide the latch plate into the buckle
until you hear a

⬙click.⬙

In Automatic Locking Mode, the shoulder belt is automati-
cally pre-locked. The seat belt will still retract to remove
any slack in the shoulder belt. Use the Automatic Locking
Mode anytime a child restraint is installed in a seating
position that has a seat belt with this feature. Children 12
years old and under should always be properly restrained
in the rear seat of a vehicle with a rear seat.

Automatic Locking Retractor (ALR) Locations

208

SAFETY

WARNING!

• Never place a rear-facing child restraint in front of an

air bag. A deploying passenger front air bag can
cause death or serious injury to a child 12 years or
younger, including a child in a rear-facing child
restraint.

• Never install a rear-facing child restraint in the front

seat of a vehicle. Only use a rear-facing child re-
straint in the rear seat. If the vehicle does not have a
rear seat, do not transport a rear-facing child restraint
in that vehicle.

How To Engage The Automatic Locking Mode

1. Buckle the combination lap and shoulder belt.

2. Grasp the shoulder portion and pull downward until

the entire seat belt is extracted.

3. Allow the seat belt to retract. As the seat belt retracts,

you will hear a clicking sound. This indicates the seat
belt is now in the Automatic Locking Mode.

How To Disengage The Automatic Locking Mode

Unbuckle the combination lap/shoulder belt and allow it
to retract completely to disengage the Automatic Locking
Mode and activate the vehicle sensitive (emergency) lock-
ing mode.

WARNING!

• The seat belt assembly must be replaced if the

switchable Automatic Locking Retractor (ALR) fea-
ture or any other seat belt function is not working
properly when checked according to the procedures
in the Service Manual.

• Failure to replace the seat belt assembly could in-

crease the risk of injury in collisions.

• Do not use the Automatic Locking Mode to restrain

occupants who are wearing the seat belt or children
who are using booster seats. The locked mode is only
used to install rear-facing or forward-facing child
restraints that have a harness for restraining the
child.

Supplemental Active Head Restraints (AHR)

These head restraints are passive, deployable components,
and vehicles with this equipment cannot be readily iden-
tified by any markings, only through visual inspection of
the head restraint. The head restraint will be split in two
halves, with the front half being soft foam and trim, the
back half being decorative plastic.

How The Active Head Restraints (AHR) Work

The Occupant Restraint Controller (ORC) determines
whether the severity or type of rear impact will require the
Active Head Restraints (AHR) to deploy. If a rear impact
requires deployment, both the driver and front passenger
seat AHRs will be deployed.

When AHRs deploy during a rear impact, the front half of
the head restraint extends forward to minimize the gap
between the back of the occupant’s head and the AHR. This
system is designed to help prevent or reduce the extent of
injuries to the driver and front passenger in certain types of
rear impacts.

NOTE:

The Active Head Restraints (AHR) may or may not

deploy in the event of a front or side impact. However, if
during a front impact, a secondary rear impact occurs, the
AHR may deploy based on the severity and type of the
impact.

Active Head Restraint (AHR) Components:

Active Head Restraint (AHR) Components

1 — Head Restraint Front Half (Soft Foam And Trim)
2 — Head Restraint Back Half (Decorative Plastic Rear Cover)
3 — Head Restraint Guide Tubes
4 — Seat Back

SAFETY

WARNING!

• All occupants, including the driver, should not oper-

ate a vehicle or sit in a vehicle’s seat until the head
restraints are placed in their proper positions in
order to minimize the risk of neck injury in the event
of a collision.

• Do not place items over the top of the Active Head

Restraint, such as coats, seat covers or portable DVD
players. These items may interfere with the opera-
tion of the Active Head Restraint in the event of a
collision and could result in serious injury or death.

• Active Head Restraints may be deployed if they are

struck by an object such as a hand, foot or loose
cargo. To avoid accidental deployment of the Active
Head Restraint, ensure that all cargo is secured, as
loose cargo could contact the Active Head Restraint
during sudden stops. Failure to follow this warning
could cause personal injury if the Active Head Re-
straint is deployed.

NOTE:

For more information on properly adjusting and

positioning the head restraint, refer to “Head Restraints” in
“Getting To Know Your Vehicle.”

Resetting Active Head Restraints (AHR)

If the Active Head Restraints are triggered during a colli-
sion, the front half of the head restraint will be extended
forward and separated from the rear half of the head
restraint (See Image). Do not drive your vehicle after the
AHRs have deployed. The head restraint must be reset into
the original position to best protect the occupant for all
types of collisions. An authorized FCA US LLC dealer must
reset the AHRs on the driver’s and front passenger’s seat
before driving. Personally attempting to reset the AHRs
may result in damage to the AHRs that could impair their
function.
