192 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.
Four-Pin Connector
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.

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
The DRIVE range can be selected when towing. The trans-
mission controls include a drive strategy to avoid frequent
shifting when towing. However, if frequent shifting does
occur while in DRIVE, use the Electronic Range Select (ERS)
shift control to select a lower gear range.
NOTE:
Using a lower gear range while operating the vehicle under
heavy loading conditions will improve performance and
extend transmission life by reducing excessive shifting and
heat build up. This action will also provide better engine
braking.

Mounting Spare Tire7. Lower the vehicle by turning the jack screw to the left.
Refer to “Torque Specifications” in “Technical Specifica -
tions” for proper wheel lug bolt torque.
8. Lower the jack to its fully-closed position.
9. Stow the cable and wheel spacer before driving the vehicle. Refer to “Vehicles With Alloy Wheels” in this
section for instructions on stowing alloy wheels.
10. Stow the jack and tools under the driver’s seat.
11. Check the spare tire pressure as soon as possible. Correct the tire pressure, as required.

12. When you place the spare tire back on the winch or if you carry the tire in need of repair on the winch, always check
that the tire is properly secured under the vehicle by pushing
on the stowed tire under the rear bumper at the back of the
vehicle. If the tire has motion when pushed, use the tools to
re-tighten the winch until a loud click is heard.

WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not fully tighten the wheel bolts until the vehicle has
been lowered. Failure to follow this warning may result
in serious injury.
CAUTION!
Be sure to mount the spare tire with the valve stem facing
outward. The vehicle could be damaged if the spare tire
is mounted incorrectly.
WARNING!
A loose tire or jack thrown forward in a collision or hard
stop could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire repaired or
replaced immediately.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial towing service.
WARNING!
Fast spinning tires can be dangerous. Forces generated
by excessive wheel speeds may cause damage, or even
failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster
than 30 mph (48 km/h) or for longer than 30 seconds
continuously without stopping when you are stuck and
do not let anyone near a spinning wheel, no matter what
the speed.
CAUTION!
• When “rocking” a stuck vehicle by shifting between DRIVE and REVERSE, do not spin the wheels faster
than 15 mph (24 km/h), or drivetrain damage may
result.

• Revving the engine or spinning the wheels too fast may lead to transmission overheating and failure. It can also damage
the tires. Do not spin the wheels above 30 mph (48 km/h)
while in gear (no transmission shifting occurring).

IN CASE OF EMERGENCY 239
Proper towing or lifting equipment is required to prevent
damage to your vehicle. Use only tow bars and other equip-
ment designed for this purpose, following equipment manu-
facturer’s instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main structural
members of the vehicle, not to bumpers or associated
brackets. State and local laws regarding vehicles under tow
must be observed.
If you must use the accessories (wipers, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
mode.
If the ignition key is unavailable, or the vehicle's battery is
discharged, refer to “Gear Selector Override” in this section
for instructions on shifting the transmission out of PARK (P)
for towing. The manufacturer recommends towing your vehicle with all
four wheels OFF the ground using a flatbed.
If flatbed equipment is not available, this vehicle must be
towed with the front wheels OFF the ground (using a towing
dolly, or wheel lift equipment with the front wheels raised).
CAUTION!
• Do not use sling type equipment when towing. Vehicle damage may occur.
• When securing the vehicle to a flat bed truck, do not attach to front or rear suspension components. Damage
to your vehicle may result from improper towing.
CAUTION!
Towing this vehicle in violation of the above
requirements can cause severe transmission damage.
Damage from improper towing is not covered under the
New Vehicle Limited Warranty.

SERVICING AND MAINTENANCE 255
(Continued)
To minimize the possibility of catalytic converter damage:
• Do not interrupt the ignition when the transmission is ingear 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.
Cooling System
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with fresh
OAT coolant (conforming to MS.90032) by an authorized
dealer. Check the front of the A/C condenser for any accu-
mulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the face
of the condenser.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the
coolant recovery bottle and radiator. Inspect the entire
system for leaks. DO NOT REMOVE THE COOLANT PRES -
SURE CAP WHEN THE COOLING SYSTEM IS HOT.
WARNING!
• You or others can be badly burned by hot engine coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never open a cooling system pressure cap when the
radiator or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry away from the radiator cooling fan when the hood is raised. The fan
starts automatically and may start at any time, whether
the engine is running or not.
• When working near the radiator cooling fan, discon -
nect the fan motor lead or turn the ignition to the OFF
mode. The fan is temperature controlled and can start at
any time the ignition is in the ON mode.
