Jeep Grand Cherokee (2019 year). Instruction

PARKING BRAKE

Before leaving the vehicle, make sure that the parking
brake is fully applied and place the gear selector in the
PARK position.

The foot operated parking brake is located below the lower
left corner of the instrument panel. To apply the park
brake, firmly push the park brake pedal fully. To release the
parking brake, press the park brake pedal a second time
and let your foot up as you feel the brake disengage.

When the parking brake is applied with the ignition switch
in the ON mode, the Brake Warning Light in the instru-
ment cluster will illuminate.

NOTE:
• When the parking brake is applied and the transmission

is placed in gear, the Brake Warning Light will flash. If
vehicle speed is detected, a chime will sound to alert the
driver. Fully release the parking brake before attempting
to move the vehicle.

• This light only shows that the parking brake is applied.

It does not show the degree of brake application.

When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. Apply the parking brake
before placing the gear selector in PARK, otherwise the
load on the transmission locking mechanism may make it
difficult to move the gear selector out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.

STARTING AND OPERATING

WARNING!

• Never use the PARK position as a substitute for the

parking brake. Always apply the parking brake fully
when parked to guard against vehicle movement and
possible injury or damage.

• When leaving the vehicle, always remove the key fob

from the ignition and lock your vehicle.

• Never leave children alone in a vehicle, or with

access to an unlocked vehicle. Allowing children to
be in a vehicle unattended is dangerous for a number
of reasons. A child or others could be seriously or
fatally injured. Children should be warned not to
touch the parking brake, brake pedal or the gear
selector.

• When leaving the vehicle, always make sure the

keyless ignition node is in the OFF mode, remove the
key fob from the vehicle and lock the vehicle.

• Do not leave the key fob in or near the vehicle or in

a location accessible to children, and do not leave the
ignition of a vehicle equipped with Keyless Enter-
N-Go in the ACC or ON/RUN mode. A child could
operate power windows, other controls, or move the
vehicle.

WARNING! (Continued)

• Be sure the parking brake is fully disengaged before

driving; failure to do so can lead to brake failure and
a collision.

• Always fully apply the parking brake when leaving

your vehicle, or it may roll and cause damage or
injury. Also be certain to leave the transmission in
PARK. Failure to do so may allow the vehicle to roll
and cause damage or injury.

CAUTION!

If the Brake Warning Light remains on with the park-
ing brake released, a brake system malfunction is
indicated. Have the brake system serviced by an au-
thorized dealer immediately.

AUTOMATIC TRANSMISSION

WARNING!

• Never use the PARK position as a substitute for the

parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.

• Your vehicle could move and injure you and others if

it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the
brake pedal released. Make sure the transmission is
in PARK before exiting the vehicle.

• The transmission may not engage PARK if the ve-

hicle is moving. Always bring the vehicle to a
complete stop before shifting to PARK, and verify
that the transmission gear position indicator solidly
indicates PARK (P) without blinking. Ensure that the
vehicle is completely stopped, and the PARK posi-
tion is properly indicated, before exiting the vehicle.

• It is dangerous to shift out of PARK or NEUTRAL if

the engine speed is higher than idle speed. If your
foot is not firmly pressing the brake pedal, the

WARNING! (Continued)

vehicle could accelerate quickly forward or in re-
verse. You could lose control of the vehicle and hit
someone or something. Only shift into gear when the
engine is idling normally and your foot is firmly
pressing the brake pedal.

• Unintended movement of a vehicle could injure

those in or near the vehicle. As with all vehicles, you
should never exit a vehicle while the engine is
running. Before exiting a vehicle, always come to a
complete stop, then apply the parking brake, shift
the transmission into PARK, and turn the ignition
OFF. When the ignition is in the OFF mode, the
transmission is locked in PARK, securing the vehicle
against unwanted movement.

• When exiting the vehicle, always make sure the

ignition is in the OFF mode, remove the key fob from
the vehicle, and lock the vehicle.

• Never leave children alone in a vehicle, or with

mission gear selector.

• Do not leave the key fob in or near the vehicle (or in

a location accessible to children), and do not leave
the ignition in the ACC or ON/RUN mode. A child
could operate power windows, other controls, or
move the vehicle.

CAUTION!

Damage to the transmission may occur if the following
precautions are not observed:

• Shift into or out of PARK or REVERSE only after the

vehicle has come to a complete stop.

• Do not shift between PARK, REVERSE, NEUTRAL,

or DRIVE when the engine is above idle speed.

• Before shifting into any gear, make sure your foot is

firmly pressing the brake pedal.

NOTE:

You must press and hold the brake pedal while

shifting out of PARK.

Ignition Park Interlock

This vehicle is equipped with an Ignition Park Interlock
which requires the transmission to be in PARK before the
ignition can be turned to the OFF mode. This helps the
driver avoid inadvertently leaving the vehicle without
placing the transmission in PARK. This system also locks
the transmission in PARK whenever the ignition is in the
OFF mode.

NOTE:

The transmission is NOT locked in PARK when the

ignition is in the ACC mode (even though the engine will
be off). Ensure that the transmission is in PARK, and the
ignition is OFF (not in ACC mode) before exiting the
vehicle.

Brake/Transmission Shift Interlock System

This vehicle is equipped with a Brake Transmission Shift
Interlock system (BTSI) that holds the transmission gear
selector in PARK unless the brakes are applied. To shift the
transmission out of PARK, the engine must be running and
the brake pedal must be pressed. The brake pedal must
also be pressed to shift from NEUTRAL into DRIVE or
REVERSE when the vehicle is stopped or moving at low
speeds.

STARTING AND OPERATING

263

Fuel Economy (ECO) Mode

The Fuel Economy (ECO) mode can improve the vehicle’s
overall fuel economy during normal driving conditions.
Push the “ECO” switch in the center stack of the instru-
ment panel to activate or disable ECO mode. A light on the
switch indicates when ECO mode is disabled.

When the Fuel Economy (ECO) Mode is engaged, the
vehicle control systems will change the following:
• The transmission will upshift sooner and downshift

later.

• The overall driving performance will be more conserva-

tive.

• Vehicles with Quadra-Lift air suspension will operate in

⬙Aero⬙ mode over a broader speed range. Refer to the
section on Quadra-Lift for further information.

• Some ECO mode functions may be temporarily inhib-

ited based on temperature and other factors.

Active Noise Cancellation — If Equipped

Your vehicle is equipped with an Active Noise Cancellation
System. This system uses four microphones embedded in
the headliner to detect undesirable exhaust noise, which
sometimes occurs when operating in specific driving con-
ditions such as ECO and Tow mode. An onboard frequency
generator creates counteracting sound waves through the
audio system to help keep the vehicle quiet.

Eight–Speed Automatic Transmission

The transmission gear range (PRNDM) is displayed both
beside the gear selector and in the instrument cluster. To
select a gear range, press the lock button on the gear
selector and move the selector rearward or forward. To
shift the transmission out of PARK, the engine must be
running and the brake pedal must be pressed. You must
also press the brake pedal to shift from NEUTRAL into

Fuel Economy Mode Switch

264

STARTING AND OPERATING

DRIVE or REVERSE when the vehicle is stopped or mov-
ing at low speeds. Select the DRIVE range for normal
driving.

NOTE:

In the event of a mismatch between the gear

selector position and the actual transmission gear (for
example, driver selects PARK while driving), the position
indicator will blink continuously until the selector is re-
turned to the proper position, or the requested shift can be
completed.

The electronically-controlled transmission adapts its shift
schedule based on driver inputs, along with environmental
and road conditions. The transmission electronics are self-
calibrating; therefore, the first few shifts on a new vehicle
may be somewhat abrupt. This is a normal condition, and
precision shifts will develop within a few hundred miles
(kilometers).

Only shift from DRIVE to PARK or REVERSE when the
accelerator pedal is released and the vehicle is stopped. Be
sure to keep your foot on the brake pedal when shifting
between these gears.

The transmission gear selector provides PARK, REVERSE,
NEUTRAL, DRIVE and MANUAL (AutoStick) shift posi-
tions. Manual shifts can be made using the AutoStick shift
control. Toggling the gear selector forward (-) or rearward

(+) while in the MANUAL (AutoStick) position (beside the
DRIVE position), or tapping the shift paddles (+/-), if
equipped, will manually select the transmission gear, and
will display the current gear in the instrument cluster.
Refer to

⬙AutoStick⬙ in this section for further information.

NOTE:

If the gear selector cannot be moved to the PARK,

REVERSE, or NEUTRAL position (when pushed forward),
it is probably in the AutoStick (+/-) position (beside the
DRIVE position). In AutoStick mode, the transmission gear
(1, 2, 3, etc.) is displayed in the instrument cluster. Move
the gear selector to the right (into the DRIVE [D] position)
for access to PARK, REVERSE, and NEUTRAL.

Gear Ranges

Do not depress the accelerator pedal when shifting from
PARK or NEUTRAL into another gear range.

NOTE:

After selecting any gear range, wait a moment to

allow the selected gear to engage before accelerating. This
is especially important when the engine is cold.

PARK (P)

This range supplements the parking brake by locking the
transmission. The engine can be started in this range.
Never attempt to use PARK while the vehicle is in motion.
Apply the parking brake when exiting the vehicle in this
range.

When parking on a level surface, you may shift the
transmission into PARK first, and then apply the parking
brake.

When parking on a hill, apply the parking brake before
shifting the transmission to PARK. As an added precau-
tion, turn the front wheels toward the curb on a downhill
grade and away from the curb on an uphill grade.

When exiting the vehicle, always:
• Apply the parking brake,
• Shift the transmission into PARK,
• Turn the ignition OFF and,
• Remove the key fob from the vehicle.

NOTE:

On four-wheel drive vehicles be sure that the

transfer case is in a drive position.

WARNING!

• Never use the PARK position as a substitute for the

parking brake. Always apply the parking brake fully
when exiting the vehicle to guard against vehicle
movement and possible injury or damage.

• Your vehicle could move and injure you and others if

it is not in PARK. Check by trying to move the
transmission gear selector out of PARK with the

267

CAUTION!

• Before moving the transmission gear selector out of

PARK, you must start the engine, and also press the
brake pedal. Otherwise, damage to the gear selector
could result.

• DO NOT race the engine when shifting from PARK

or NEUTRAL into another gear range, as this can
damage the drivetrain.

The following indicators should be used to ensure that you
have properly engaged the transmission into the PARK
position:
• When shifting into PARK, push the lock button on the

gear selector and firmly move the selector all the way
forward until it stops and is fully seated.

• Look at the transmission gear position display and

verify that it indicates the PARK position (P), and is not
blinking.

• With brake pedal released, verify that the gear selector

will not move out of PARK.

NOTE:

If the gear selector cannot be moved to the PARK

position (when pushed forward), it is probably in the
AutoStick (+/-) position (beside the DRIVE position). In
AutoStick mode, the transmission gear (1, 2, 3, etc.) is
displayed in the instrument cluster. Move the gear selector
to the right (into the DRIVE [D] position) for access to
PARK, REVERSE, and NEUTRAL.

REVERSE (R)

This range is for moving the vehicle backward. Shift into
REVERSE only after the vehicle has come to a complete
stop.

NEUTRAL (N)

Use this range when the vehicle is standing for prolonged
periods with the engine running. Apply the parking brake
and shift the transmission into PARK if you must exit the
vehicle.

268

STARTING AND OPERATING

WARNING!

Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.

CAUTION!

Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage.
Refer to “Recreational Towing” in “Starting And Op-
erating” and “Towing A Disabled Vehicle” in “In Case
Of Emergency” for further information.

DRIVE (D)

This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions.

When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control
(refer to

⬙AutoStick⬙ in this section for further information)

to select a lower gear. Under these conditions, using a
lower gear will improve performance and extend transmis-
sion life by reducing excessive shifting and heat buildup.

During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.

MANUAL (M)

The MANUAL (M, +/-) position (beside the DRIVE posi-
tion) enables full manual control of transmission shifting
(also known as AutoStick mode; refer to “AutoStick” in this
section for further information). Toggling the gear selector
forward (-) or rearward (+) while in the MANUAL
(AutoStick) position will manually select the transmission
gear, and will display the current gear in the instrument
cluster.

STARTING AND OPERATING

269

Transmission Limp Home Mode

Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.

In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:

NOTE:

In cases where the instrument cluster message

indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at an authorized dealer).

1. Stop the vehicle.

2. Shift the transmission into PARK, if possible. If not, shift

the transmission to NEUTRAL.

3. Push and hold the ignition switch until the engine turns

OFF.

4. Wait approximately 30 seconds.

5. Restart the engine.

6. Shift into the desired gear range. If the problem is no

longer detected, the transmission will return to normal
operation.

NOTE:

Even if the transmission can be reset, we recom-

mend that you visit an authorized dealer at your earliest
possible convenience. An authorized dealer has diagnostic
equipment to assess the condition of your transmission.

If the transmission cannot be reset, authorized dealer
service is required.

AutoStick

AutoStick is a driver-interactive transmission feature pro-
viding manual shift control, giving you more control of the
vehicle. AutoStick allows you to maximize engine braking,
eliminate undesirable upshifts and downshifts, and im-
prove overall vehicle performance. This system can also
provide you with more control during passing, city driv-
ing, cold slippery conditions, mountain driving, trailer
towing, and many other situations.

270

STARTING AND OPERATING

Operation

To activate AutoStick mode, move the gear selector into the
MANUAL (M) position (beside the DRIVE position), or tap
one of the shift paddles on the steering wheel (if equipped).
Tapping the (-) shift paddle (if equipped) to enter
AutoStick mode will downshift the transmission to the
next lower gear, while tapping (+) to enter AutoStick mode
will retain the current gear. The current transmission gear
will be displayed in the instrument cluster. In AutoStick
mode, you can use the gear selector (in the MANUAL
position), or the shift paddles (if equipped), to manually
shift the transmission. Tapping the gear selector forward (-)
while in the MANUAL (M) position, or tapping the (-) shift
paddle (if equipped), will downshift the transmission to
the next lower gear. Tapping the selector rearward (+) (or
tapping the (+) shift paddle, if equipped) will command an
upshift.

NOTE:

The shift paddles (if equipped) may be disabled (or

re-enabled, as desired) using the Uconnect Personal Set-
tings.

In AutoStick mode, the transmission will shift up or down
when (+/-) is manually selected by the driver (using the
gear selector, or the shift paddles, if equipped), unless an

engine lugging or overspeed condition would result. It will
remain in the selected gear until another upshift or down-
shift is chosen, except as described below.
• The transmission will automatically downshift as the

vehicle slows (to prevent engine lugging) and will
display the current gear.

• The transmission will automatically downshift to first

gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.

• You can start out, from a stop, in first or second gear (or

third gear, in 4LO range, Snow mode, or Sand mode).
Tapping (+) (at a stop) will allow starting in second gear.
Starting out in second or third gear can be helpful in
snowy or icy conditions.

• If a requested downshift would cause the engine to

over-speed, that shift will not occur.

• The system will ignore attempts to upshift at too low of

a vehicle speed.

• Holding the (-) paddle depressed (if equipped), or

holding the gear selector in the (-) position, will down-
shift the transmission to the lowest gear possible at the
current speed.

STARTING AND OPERATING

271

• Transmission shifting will be more noticeable when

AutoStick is enabled.

• The system may revert to automatic shift mode if a fault

or overheat condition is detected.

NOTE:

When Selec-Speed or Hill Descent Control is en-

abled, AutoStick is not active.

To disengage AutoStick, return the gear selector to the
DRIVE position, or press and hold the (+) shift paddle (if
equipped, and the gear selector is already in DRIVE) until

⬙D⬙ is once again indicated in the instrument cluster. You
can shift in or out of AutoStick at any time without taking
your foot off the accelerator pedal.

WARNING!

Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

SPORT MODE — IF EQUIPPED

Your vehicle is equipped with a Sport Mode feature. This
mode is a configuration set up for typical enthusiast
driving. The engine, transmission, and steering systems are
all set to their SPORT settings. Sport Mode will provide
improved throttle response and modified shifting for an
enhanced driving experience, as well the greatest amount
of steering feel. This mode may be activated and deacti-
vated by pushing the Sport button on the instrument panel
switch bank.

FOUR WHEEL DRIVE OPERATION

Quadra-Trac I Operating Instructions/Precautions
— If Equipped

The Quadra-Trac I is a single-speed (HI range only) trans-
fer case, which provides convenient full-time four-wheel
drive. No driver interaction is required. The Brake Traction
Control (BTC) System, which combines standard ABS and
Traction Control, provides resistance to any wheel that is
slipping to allow additional torque transfer to wheels with
traction.

NOTE:

The Quadra-Trac I system is not appropriate for

conditions where 4WD LOW range is recommended. Refer
to “Off-Road Driving Tips” in “Starting And Operating”

Quadra-Trac II Operating Instructions/Precautions
— If Equipped

The Quadra-Trac II transfer case is fully automatic in the
normal driving 4WD AUTO mode. The Quadra-Trac II
transfer case provides three mode positions:
• 4WD HI
• NEUTRAL
• 4WD LOW

This transfer case is fully automatic in the 4WD HI mode.

When additional traction is required, the 4WD LOW
position can be used to lock the front and rear driveshafts
together and force the front and rear wheels to rotate at the
same speed. The 4WD LOW position is intended for loose,
slippery road surfaces only. Driving in the 4WD LOW
position on dry, hard-surfaced roads may cause increased
tire wear and damage to driveline components.

When operating your vehicle in 4WD LOW, the engine
speed is approximately three times that of the 4WD HI
position at a given road speed. Take care not to overspeed
the engine and do not exceed 25 mph (40 km/h).

Proper operation of four-wheel drive vehicles depends on
tires of equal size, type, and circumference on each wheel.
Any difference will adversely affect shifting and cause
damage to the transfer case.

Because four-wheel drive provides improved traction,
there is a tendency to exceed safe turning and stopping
speeds. Do not go faster than road conditions permit.

STARTING AND OPERATING

273

WARNING!

You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL position without first fully engaging the park-
ing brake. The transfer case NEUTRAL position disen-
gages both the front and rear drive shafts from the
powertrain and will allow the vehicle to roll, even if
the transmission is in PARK. The parking brake
should always be applied when the driver is not in the
vehicle.

Shift Positions

For additional information on the appropriate use of each
4WD system mode position, see the information below:

4WD AUTO

This range is used on surfaces such as ice, snow, gravel,
sand, and dry hard pavement.

NOTE:

Refer to “Selec-Terrain — If Equipped” further on

in this section for further information on the various
positions and their intended usages.

NEUTRAL

This range disengages the driveline from the powertrain. It
is to be used for flat towing behind another vehicle. Refer
to “Recreational Towing” in “Starting And Operating” for
further information.

WARNING!

4WD LOW

This range is for low speed four-wheel drive. It provides an
additional gear reduction which allows for increased
torque to be delivered to both the front and rear wheels
while providing maximum pulling power for loose, slip-
pery road surfaces only. Do not exceed 25 mph (40 km/h).

274
