2013 JEEP GRAND CHEROKEE tow

WARNING!(Continued)
•Vehicles with trailers should not be parked
on a grade. When parking, apply the park-
ing brake on the tow vehicle. Put the tow
vehicle transmission in PARK. For four-
wheel drive vehicles, make sure the trans-
fer case is not in NEUTRAL. Always, block
or "chock" the trailer wheels.
• GCWR must not be exceeded.
• Total weight must be distributed be-
tween the tow vehicle and the trailer
such that the following four ratings are
not exceeded:
1. GVWR
2. GTW
3. GAWR
4. Trailer tongue weight rating for the trailer hitch utilized . Towing Requirements – Tires
•
Proper tire inflation pressures are essential
to the safe and satisfactory operation of your
vehicle. Refer to “Tires – General Informa-
tion” in “Starting and Operating” for proper
tire inflation procedures.
• 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 – General Information” in “Starting and
Operating” for proper inspection procedure.
• When replacing tires, refer to “Tires – Gen-
eral Information” in “Starting and Operating”
for proper tire replacement procedures. Re-
placing tires with a higher load carrying ca-
pacity will not increase the vehicle’s GVWR
and GAWR limits.
Towing Requirements – Trailer Brakes
• Do not interconnect the hydraulic brake sys-
tem or vacuum system of your vehicle with
that of the trailer. This could cause inad-
equate braking and possible personal injury. •
An electronically-actuated trailer brake con-
troller is required when towing a trailer with
electronically-actuated 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 (454 kg), and required for
trailers in excess of 1,654 lbs (750 kg).
WARNING!
•Do not connect trailer brakes to your vehi-
cle’s hydraulic brake lines. It can overload
your brake system 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
distance. 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.

trailer size, stop lights and turn signals on the
trailer are required for motoring safety.
The Trailer Tow Package includes a 13 pin
wiring harness. Use a factory approved trailer
harness and connector.
NOTE:
Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to
the vehicle but you must mate the harness to a
trailer connector.

Towing TipsBefore setting out on a trip, practice turning,
stopping and backing the trailer in an area away
from heavy traffic.
Automatic Transmission
The DRIVE range can be selected when towing.
The transmission controls include an adaptive
drive strategy to avoid frequent shifting when
towing. However, if frequent shifting does occur
while in DRIVE, select TOW mode, or use the
AutoStick® shift control to select a lower gear.
NOTE:
Using TOW mode or selecting a lower gear
while operating the vehicle under heavy load-
ing conditions, will improve performance and
extend transmission life by reducing exces-
sive shifting and heat buildup. This action will
also provide better engine braking.
If you REGULARLY tow a trailer for more than
45 minutes of continuous operation, then change
the transmission fluid and filter(s) as specified for
"police, taxi, fleet, or frequent trailer towing. Refer
to the “Maintenance Schedule” for the proper
maintenance intervals.
Electronic Speed Control – If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experi-
ence 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
overheating, take the following actions:
City Driving
When stopped for short periods of time, shift the
transmission into NEUTRAL and increase en-
gine idle speed.
Highway Driving
Reduce speed.
Air Conditioning
Turn off temporarily.

Trailer Hitch Attaching Points
Your vehicle will require extra equipment to tow
a trailer safely and efficiently. The trailer tow
hitch must be attached to your vehicle using the
provided attaching points on the vehicle’s
frame. Refer to the following chart to determine
the accurate attaching points. Other equipment,
such as trailer sway controls and braking equip-
ment, trailer equalizing (leveling) equipment
and low profile mirrors, may also be required or
strongly recommended.Trailer Tow Hitch Attaching Points AndOverhang Dimensions
