Cooling System Tips — Trailer Towing
To reduce potential for engine and transmission over-
heating, take the following actions in high ambient
temperatures:
•City Driving—when stopped, put the transmission in
N (Neutral) and increase the engine idle speed.
•Highway Driving—reduce your speed.
•Air Conditioning—turn it off temporarily.
•Hilly Terrain—Turn overdrive off.
See Cooling System Operating information in the Service
and Maintenance section of this manual for more infor-
mation.

CAUTION!
Internal damage to the transfer case will occur if a
front or rear wheel lift is used when recreational
towing.
NOTE:Both the Manual Shift and Electronic Shift
transfer cases must be shifted into Neutral (N) for
recreational towing. Automatic transmissions must be
placed in P (Park) position for recreational towing.
Manual transmissions must be left in gear (not in neutral)
for recreational towing. Refer below for the proper trans-
fer case Neutral shifting procedure for your vehicle.
Recreational Towing Procedure — Manual Shift
Transfer Case — If Equipped
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 N (NEUTRAL) before
recreational towing to prevent damage to internal
parts.
1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Depress the brake pedal.
4. Shift automatic transmission to N (NEUTRAL), or

Returning to Normal Operation — Manual Shift
Transfer Case
Use the following procedure to prepare your vehicle for
normal usage:
1. Bring the vehicle to a complete stop.
2. Shut OFF the engine.
3. Depress the brake pedal.
4. Shift automatic transmission to N (NEUTRAL), or

6. Shift automatic transmission into P (Park).
WARNING!
You or others could be injured if you leave the
vehicle unattended with the transfer case in the N
(NEUTRAL) position without first fully engaging
the parking brake. The transfer case N (NEUTRAL)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the ve-
hicle to move regardless of the transmission posi-
tion. The parking brake should always be applied
when the driver is not in the vehicle.

308 STARTING AND OPERATING

Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the “4L” position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.
•Turn on the Hazard Warning Flasher.
•Block both the front and rear
of the wheel diagonally oppo-
site the jacking position. For
example, if the right front
wheel is being changed, block
the left rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
WHAT TO DO IN EMERGENCIES 319

Your vehicle is equipped with two 12–volt batteries. If it
becomes necessary to use a booster battery, with jumper
cables, to start a vehicle’s engine because its batteries are
discharged, the following procedure should be followed:
Set the parking brake and place an automatic transmis-
sion in PARK (or NEUTRAL for a manual transmission).
Turn off lights, heater and other electrical loads. Observe
charge indicator (if equipped) in both batteries. If indica-
tor (if equipped) is light or yellow on either battery,
replace that battery.CAUTION!
Use the Jump Start Procedure only when the charge
indicator (if equipped) in both batteries is dark in
the center. Do not attempt jump starting when either
battery charge indicator (if equipped) is bright or
yellow. If charge indicator (if equipped) has a green
dot in the center, failure to start is not due to a
discharged battery and cranking system should be
checked.
1. Attach one jumper cable to the positive terminal of
booster battery and the other end of the same cable to the
positive terminal of the discharged battery.
