2018 JEEP CHEROKEE TRAILHAWK towing

WARNING!(Continued)
•When hauling cargo, or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance, or damage
to brakes, axle, engine, transmission, steering, sus-
pension, chassis structure, or tires.
• Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
frame or hook retainers of the vehicle hitch. Cross
the chains under the trailer tongue and allow enough
slack for turning corners.
• Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in
PARK. Always block or chockthe trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Tongue weight rating for the trailer hitch utilized.

•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).

Recreational Towing — 4x4 Models With 2-Speed
Power Transfer Unit
The power transfer unit 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 4WD selector switch. Shifts into and out of NEUTRAL
(N) can take place with the selector switch in any mode
position.

Front-Wheel Drive (FWD) Models
The manufacturer recommends towing your vehicle with
all four wheelsOFFof the ground using a flatbed.
If flatbed equipment is not available, this vehicle must be
towed with the front wheels OFFof the ground (using a
towing dolly, or wheel lift equipment with the front wheels
raised).
Ensure that the Electric Park Brake is released, and remains
released, while being towed. The Electric Park Brake does
not need to be released, if all four wheels are off the
ground.

4x4 Models With 2–Speed Power Transfer Unit
The manufacturer recommends towing with all four
wheelsOFFthe ground.
Acceptable methods are to tow the vehicle on a flatbed or
with one end of the vehicle raised and the opposite end on
a towing dolly.
If flatbed equipment is not available and the Power Trans-
fer Unit is operable, vehicles with a 2–speed Power Trans-
fer Unit may be towed (in the forward direction, with ALL
wheels on the ground), under the following conditions:
• The Power Transfer Unit must be in NEUTRAL (N).
• The transmission must be in PARK.
• Ensure that the Electric Park Brake is released, and
remains released, while being towed.
Refer to “Recreational Towing” in “Starting And Operat-
ing” for detailed instructions.

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE: Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you. In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
•
Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
