Jeep Grand Cherokee (2019 year). Instruction

• Check the trailer tires for proper tire inflation pressures

before trailer usage.

• Check for signs of tire wear or visible tire damage before

towing a trailer. Refer to “Tires” in “Servicing And
Maintenance” for the proper inspection procedure.

• When replacing tires, refer to “Tires” in “Servicing And

Maintenance” for the proper tire replacement proce-
dures. Replacing tires with a higher load carrying capac-
ity will not increase the vehicle’s GVWR and GAWR
limits.

Towing Requirements — Trailer Brakes
• Do not interconnect the hydraulic brake system or

vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible per-
sonal injury.

• An electronically actuated trailer brake controller is

required when towing a trailer with electronically actu-
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.

• Trailer brakes are recommended for trailers over

1,000 lbs (453 kg) and required for trailers in excess of
2,000 lbs (907 kg).

WARNING!

• Do not connect trailer brakes to your vehicle’s hy-

draulic brake lines. It can overload your brake sys-
tem and cause it to fail. You might not have brakes
when you need them and could have an accident.

• Towing any trailer will increase your stopping dis-

tance. When towing, you should allow for additional
space between your vehicle and the vehicle in front
of you. Failure to do so could result in an accident.

CAUTION!

If the trailer weighs more than 1,000 lbs (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.

STARTING AND OPERATING

Towing Requirements — Trailer Lights And Wiring

Whenever you pull a trailer, regardless of the trailer size,
stoplights and turn signals on the trailer are required for
motoring safety.

The Trailer Tow Package may include a four- and seven-pin
wiring harness. Use a factory approved trailer harness and
connector.

NOTE:

Do not cut or splice wiring into the vehicle’s wiring

harness.

The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector. Refer
to the following illustrations.

NOTE:
• Disconnect trailer wiring connector from the vehicle

before launching a boat (or any other device plugged
into vehicle’s electrical connect) into water.

• Be sure to reconnect once clear from water area.

Towing Tips

Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.

Automatic Transmission

Select the DRIVE range when towing. The transmission
controls include a drive strategy to avoid frequent shifting
when towing. However, if frequent shifting does occur
while in DRIVE, you can use the AutoStick shift control to
manually select a lower gear.

NOTE:

Using a lower gear (using the AutoStick shift

control) while operating the vehicle under heavy loading
conditions, will improve performance and extend trans-
mission life by reducing excessive shifting and heat
buildup. This action will also provide better engine brak-
ing.

AutoStick
• When using the AutoStick shift control, select the high-

est gear that allows for adequate performance and
avoids frequent downshifts. For example, choose “5” if
the desired speed can be maintained. Choose “4” or “3”
if needed to maintain the desired speed.

• To prevent excess heat generation, avoid continuous

driving at high RPM. Reduce vehicle speed as necessary
to avoid extended driving at high RPM. Return to a
higher gear or vehicle speed when grade and road
conditions allow.

STARTING AND OPERATING

Speed Control — If Equipped
• Do not use on hilly terrain or with heavy loads.
• When using the speed control, if you experience speed

drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.

• Use speed control in flat terrain and with light loads to

maximize fuel efficiency.

Cooling System

To reduce potential for engine and transmission overheat-
ing, take the following actions:

City Driving
• In city traffic — while stopped, place the transmission in

NEUTRAL, but do not increase engine idle speed.

Highway Driving
• Reduce speed.
• Temporarily turn off air conditioning.

SNOW PLOW

Snow plows, winches, and other aftermarket equipment
should not be added to the front end of your vehicle. The
airbag crash sensors may be affected by the change in the
front end structure. The airbags could deploy unexpectedly
or could fail to deploy during a collision.

WARNING!

Do not add a snow plow, winches, or any other
aftermarket equipment to the front of your vehicle.
This could adversely affect the functioning of the
airbag system and you could be injured.

state and provincial laws. Contact state and provincial
Highway Safety offices for additional details.

• Vehicles equipped with Quadra-Lift must be placed in

Transport Mode before tying them down (from the
body) on a trailer or flatbed truck. Refer to “Quadra-
Lift” in “Starting and Operating” for more information.
If the vehicle cannot be placed in Transport mode (for
example, engine will not run), tie-downs should be
fastened over the tires using specific straps (not to the
body). Failure to follow these instructions may cause
fault codes to be set and/or cause loss of proper
tie-down tension.

Recreational Towing — Two Wheel Drive Models

DO NOT flat tow this vehicle. Damage to the drivetrain
will result.

Recreational towing (for two-wheel drive models) is al-
lowed ONLY if the rear wheels are OFF the ground. This
may be accomplished using a tow dolly or vehicle trailer. If
using a tow dolly, follow this procedure:

1. Properly secure the dolly to the tow vehicle, following

the dolly manufacturer’s instructions.

NOTE:

If vehicle is equipped with Quadra-Lift air suspen-

sion, ensure the vehicle is set to Normal Ride Height.

2. Drive the rear wheels onto the tow dolly.

3. Firmly apply the parking brake. Shift the transmission

into PARK.

4. Turn the ignition OFF.

5. Properly secure the rear wheels to the dolly, following

the dolly manufacturer’s instructions.

6. Install a suitable clamping device, designed for towing,

to secure the front wheels in the straight position.

CAUTION!

Towing with the rear wheels on the ground will cause
severe transmission damage. Damage from improper
towing is not covered under the New Vehicle Limited
Warranty.

Recreational Towing — Quadra-Trac I
(Single-Speed Transfer Case) Four-Wheel Drive
Models

Recreational towing is not allowed.

These models do not

have a NEUTRAL (N) position in the transfer case.

NOTE:

This vehicle may be towed on a flatbed or vehicle

trailer provided all four wheels are OFF the ground.

CAUTION!

Towing this vehicle in violation of the above require-
ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

Recreational Towing — Quadra–Trac II/Quadra–
Drive II Four-Wheel Drive Models

The transfer case must be shifted into NEUTRAL (N) and
the transmission must be in PARK for recreational towing.
The NEUTRAL (N) selection button is adjacent to the
transfer case selector switch. Shifts into and out of transfer
case NEUTRAL (N) can take place with the selector switch
in any mode position.

CAUTION!

• DO NOT dolly tow any 4WD vehicle. Towing with

only one set of wheels on the ground (front or rear)
will cause severe transmission and/or transfer case
damage. Tow with all four wheels either ON the
ground, or OFF the ground (using a vehicle trailer).

• Tow only in a forward direction. Towing this vehicle

backwards can cause severe damage to the transfer
case.

• The transmission must be in PARK for recreational

towing.

• Before recreational towing, perform the procedure

outlined under “Shifting into NEUTRAL (N)” to be
certain that the transfer case is fully in NEUTRAL
(N). Otherwise, internal damage will result.

• Towing this vehicle in violation of the above require-

ments can cause severe transmission and/or transfer
case damage. Damage from improper towing is not
covered under the New Vehicle Limited Warranty.

• Do not use a bumper-mounted clamp-on tow bar on

your vehicle. The bumper face bar will be damaged.

STARTING AND OPERATING

Shifting Into NEUTRAL (N)

WARNING!

You or others could be injured or killed if you leave the
vehicle unattended with the transfer case in the NEU-
TRAL (N) position without first fully engaging the
parking brake. The transfer case NEUTRAL (N) posi-
tion disengages both the front and rear driveshafts
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.

Use the following procedure to prepare your vehicle for
recreational towing.

CAUTION!

It is necessary to follow these steps to be certain that
the transfer case is fully in NEUTRAL (N) before
recreational towing to prevent damage to internal
parts.

1. Bring the vehicle to a complete stop on level ground,

with the engine running.

2. Press and hold the brake pedal.

DRIVING TIPS

On-Road Driving Tips

Utility vehicles have higher ground clearance and a nar-
rower track to make them capable of performing in a wide
variety of off-road applications. Specific design character-
istics give them a higher center of gravity than conven-
tional passenger cars.

An advantage of the higher ground clearance is a better
view of the road, allowing you to anticipate problems.
They are not designed for cornering at the same speeds as
conventional passenger cars any more than low-slung
sports cars are designed to perform satisfactorily in off-
road conditions. Avoid sharp turns or abrupt maneuvers.
As with other vehicles of this type, failure to operate this
vehicle correctly may result in loss of control or vehicle
rollover.

STARTING AND OPERATING

Off-Road Driving Tips

NOTE:

Prior to off-road driving with non-Summit models

that are also equipped with an Off Road Package, remove
the lower fascia to prevent damage. The lower fascia is
attached to the lower part of the front fascia with seven
quarter turn fasteners and can be removed by hand. The
front license plate bracket must be removed first if
equipped.

NOTE:

On Summit models the lower front fascia is not

removable.

Lower Front Fascia Removal:

1. Remove the seven quarter turn fasteners.

2. Starting on one side of the vehicle, disengage lower

fascia from the upper fascia. Grasp the portion inside
the wheel well. Pulling it downwards and toward you,
separate the tabs from the slots in the upper fascia.

3. Continue working your way across the vehicle, separat-

ing the remaining tabs from the slots in the upper fascia.

NOTE:

Do not allow the lower fascia to freely hang from

the tabs in the opposite corner as damage to lower and
upper fascia may result.

4. Store the lower fascia in a safe location.

NOTE:

It is recommend to also remove the radar sensor on

vehicle equipped to Adaptive Cruise Control (ACC). This
radar sensor is specifically calibrated to your vehicle and is
not interchangeable with other radar sensors.

If you receive a fault, see your authorized dealer

they may need to perform a sensor alignment.

Lower Front Fascia Installation

NOTE:

This will only work if you have a helper.

1. Starting at the center of the vehicle, engage a sufficient

number of tabs to support the weight of the lower fascia
(typically one or two tabs) into the upper fascia.

2. Working your way outward, engage the tabs into the

slots on one side of the vehicle.

3. Return to the center of the vehicle and repeat Step 2 to

the opposite side of the vehicle.

NOTE:

• It may be necessary to apply additional force to

individual tabs to make sure they are fully engaged.

• Do not use any tools to apply additional force to the

tabs as damage to the upper and lower fascias may
result.

4. Reinstall the seven quarter turn fasteners.

Quadra-Lift — If Equipped

When off-roading, it is recommended that the lowest
useable vehicle height that will clear the current obstacle or
terrain be selected. The vehicle height should then be
raised as required by the changes in terrain.

STARTING AND OPERATING

385

The Selec-Terrain switch will automatically change the
vehicle to the optimized height based on the Selec-Terrain
switch position. The vehicle height can be changed from
the default height for each Selec-Terrain mode by normal
use of the air suspension switches. Refer to “Four Wheel
Drive Operation” in “Starting And Operating” for further
information.

When To Use 4WD LOW Range — If Equipped

When off-road driving, shift to 4WD LOW for additional
traction. This range should be limited to extreme situations
such as deep snow, mud, or sand where additional low
speed pulling power is needed. Vehicle speeds in excess of
25 mph (40 km/h) should be avoided when in 4WD LOW
range.

WARNING!

Do not drive in 4WD-LOW Range on dry pavement;
driveline damage may result. 4WD-LOW Range locks
front and rear drivelines together and does not allow
for differential action between the front to rear drive-
shafts. Driving in 4WD-LOW on pavement will cause
driveline binding; use only on wet or slippery surfaces.

Driving Through Water

Although your vehicle is capable of driving through water,
there are a number of precautions that must be considered
before entering the water.

NOTE:

Your vehicle is capable of water fording in up to 20

inches (51 cm) of water, while crossing small rivers or
streams. To maintain optimal performance of your vehi-
cle’s heating and ventilation system it is recommended to
switch the system into recirculation mode during water
fording.

CAUTION!

When driving through water, do not exceed 5 mph
(8 km/h). Always check water depth before entering as
a precaution, and check all fluids afterward. Driving
through water may cause damage that may not be
covered by the New Vehicle Limited Warranty.

Driving through water more than a few inches/centimeters
deep will require extra caution to ensure safety and pre-
vent damage to your vehicle. If you must drive through
water, try to determine the depth and the bottom condition
(and location of any obstacles) prior to entering. Proceed

386

STARTING AND OPERATING

with caution and maintain a steady controlled speed less than
5 mph (8 km/h) in deep water to minimize wave effects.

Flowing Water

If the water is swift flowing and rising (as in storm run-off),
avoid crossing until the water level recedes and/or the
flow rate is reduced. If you must cross flowing water avoid
depths in excess of 9 inches (23 cm). The flowing water can
erode the streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are downstream
of your entry point to allow for drifting.

Standing Water

Avoid driving in standing water deeper than 20 inches
(51 cm), and reduce speed appropriately to minimize wave
effects. Maximum speed in 20 inches (51 cm) of water is
less than 5 mph (8 km/h).

Maintenance

After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to prevent
component damage.

Driving In Snow, Mud And Sand

In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a lower
gear than necessary to maintain forward motion. Over-
revving the engine can spin the wheels and traction will be
lost.

Avoid abrupt downshifts on icy or slippery roads, because
engine braking may cause skidding and loss of control.

Hill Climbing

NOTE:

Before attempting to climb a hill, determine the

conditions at the crest and/or on the other side.

Before climbing a steep hill,

shift the transmission to a

lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
