360 STARTING AND OPERATING

CAUTION!
Damage to the transmission may occur if the trans-
mission is shifted into PARK with the transfer case in
N (Neutral) and the engine running. With the trans-
fer case in N (Neutral) ensure that the engine is off
prior to shifting the transmission into PARK (refer to
steps7–8above).
Shifting Out Of Neutral (N)
Use the following procedure to prepare your vehicle for
normal usage.
1. Shift automatic transmission into NEUTRAL or de-
press clutch pedal on manual transmission.
2. Shift transfer case lever into desired position.
3. Shift automatic transmission into DRIVE or release
clutch on manual transmissions.NOTE:
When shifting out of transfer case N (Neutral)
on automatic transmission-equipped vehicles, turning
the engine off may be required to avoid gear clash.
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 driveshafts from
the powertrain and will allow the vehicle to move
despite the transmission position. The parking brake
should always be applied when the driver is not in
the vehicle.

HAZARD WARNING FLASHERS
Your vehicle’s hazard warning flasher is an emergency
warning system. When you activate it, all front and rear
directional signals will flash intermittently. Use it when
your vehicle is disabled on or near the road. It warns
other drivers to steer clear of you and your vehicle. This
is an emergency warning system, not to be used when the
vehicle is in motion.
To activate the warning flashers, press the switch on the
lower switch bank (below the climate controls). To turn
the warning flashers off, press the switch again.NOTE:With extended use, the flasher may wear down
your battery.

364 WHAT TO DO IN EMERGENCIES

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, shift transmission into
NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
Control to maximum heat, the Mode Control to floor, and
the Fan Control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads HOT
(H), pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on HOT (H), and you hear continuous
chimes, turn the engine off immediately, and call for
service.

JACKING AND TIRE CHANGING
WARNING!
•Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
•The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should
be jacked on a firm level surface only. Avoid ice or
slippery areas.
Jack Location
The jack and lug wrench are located in the rear storage
compartment. Refer to “Storage” in Section 3 of this
manual.

366 WHAT TO DO IN EMERGENCIES

Spare Tire Stowage
To remove the spare tire from the carrier, remove the tire
cover, if equipped, and remove the lug nuts with the lug
wrench turning them counterclockwise.
NOTE:If you have added aftermarket accessories to the
spare tire mounted carrier, it cannot exceed a gross
weight of 50 lbs (23 kg) including the weight of the spare
tire.
Preparations For Jacking
Park on a firm level surface, avoid ice or slippery areas,
set the parking brake and shift automatic transmission
into PARK, or manual transmission into REVERSE. Turn
OFF the ignition.
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 being hit when operating the jack
or changing the wheel.
•Turn on the hazard warning flashers. Refer to “Hazard
Warning Flashers” in this section.
•Block both the front and rear
of the wheel diagonally oppo-
site of the jacking position.
For example, if changing the
right front tire, block the left
rear wheel.
•Passengers should not remain in the vehicle when the
vehicle is being jacked.
