HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
switch bank just above the climate controls.Press the switch to turn on the Hazard Warning
flasher. When the switch is activated, all directional
turn signals will flash on and off to warn oncoming
traffic of an emergency. Press the switch a second time to
turn off the Hazard Warning flasher.
This is an emergency warning system and should not be
used when the vehicle is in motion. Use it when your
vehicle is disabled and is creating a safety hazard for
other motorists.
If it is necessary to leave the vehicle to go for service, the
Hazard Warning flasher will continue to operate with the
ignition key removed and the vehicle locked.
NOTE: With extended use, the Hazard Warning flasher
may run down your battery.
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, put the transmission in
NEUTRAL, but do not increase the engine idle speed.
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.
342 WHAT TO DO IN EMERGENCIES

NOTE:There are steps that you can take to slow down
an impending overheat condition:
•If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
•You can also turn the Temperature Control to maxi-
mum heat, the Mode Control to floor and the Blower
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.
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 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 scissor-type jack and tire changing tools are located
in a compartment behind the third row seat. Refer to
“Cargo Area Features” in Section 3 for further informa-
tion.
Spare Tire Stowage
The spare tire is stowed under the rear of the vehicle by
means of a cable winch mechanism. To remove or stow
the spare, use the jack handle to rotate the “spare tire
drive” nut. The nut is located under a plastic cover at the
center-rear of the cargo floor area, just inside the liftgate
opening.
CAUTION!
Do not use power tools to winch the tire up or down.
Impact type tools can damage the winch mechanism.

344 WHAT TO DO IN EMERGENCIES

Spare Tire Removal
Fit the jack handle extension over the drive nut. Use the
lug wrench to rotate the nut counterclockwise until the
spare is on the ground with enough slack in the cable to
allow pulling the tire out from under the vehicle.
CAUTION!
The winch mechanism is designed for use with the
jack extension tube only. Use of an air wrench or
other power tools is not recommended and can dam-
age the winch.
When the spare is clear, tilt the retainer at the end of the
cable and pull it through the center of the wheel.
Preparations For Jacking
1. Park the vehicle on a firm, level surface. Avoid ice and
slippery areas.
Lowering/Raising Spare Tire6
WHAT TO DO IN EMERGENCIES 345

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.
2. Set the parking brake.
3. Place the shift lever into PARK
4. Turn OFF the ignition.
5. Turn on the Hazard Warning flasher. 6. Block both the front and rear of the
wheel diagonally opposite of the jack-
ing position. For example, if changing
the right front tire, block the left rear
wheel. NOTE:
Passengers should not remain in the vehicle
when the vehicle is being jacked.Jacking Instructions
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
•Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
•Block the wheel diagonally opposite the wheel to
be raised.
•Set the parking brake firmly, and shift an auto-
matic transmission into PARK; a manual transmis-
sion into REVERSE.

WARNING! (Continued)
•Never start or run the engine with the vehicle on a
jack.
•Do not let anyone sit in the vehicle when it is on a
jack.
•Do not get under the vehicle when it is on a jack.
•Only use the jack in the positions indicated and
for lifting this vehicle during a tire change.
•If working on or near a roadway, be extremely
careful of motor traffic.
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.
•Turn on the Hazard Warning flasher.1. Remove the spare tire, jack, and tools from storage.
2. Loosen (but do not remove) the wheel lug nuts by
turning them to the left one turn while the wheel is still
on the ground.
3. Assemble the jack and jacking tools as shown. Connect
jack handle driver (1) to two extensions (2), then to the
lug wrench (3).

4. Locate the jack as shown. For the front axle, place it
under the front lower control arm.Do not raise the
vehicle until you are sure the jack is fully engaged. For the rear axle, place it under the axle near the wheel to
be changed. Ensure the jack is closest to the inside of the
wheel when jacking on the rear axle.

5. Raise the vehicle by turning the jack screw clockwise.
Raise the vehicle only until the tire just clears the surface
and enough clearance is obtained to install the spare tire.
Minimum tire lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
6. Remove the lug nuts and wheel.
7. Position the spare wheel/tire on the vehicle and install
the lug nuts with the cone-shaped end toward the wheel.
Lightly tighten the nuts. To avoid the risk of forcing the
vehicle off the jack, do not tighten the nuts fully until the
vehicle has been lowered.
8. Lower the vehicle by turning the jack screw counter-
clockwise, and remove the jack and wheel blocks.

9. Finish tightening the lug nuts. Push down on the
wrench while tightening for increased leverage. Alternate
nuts until each nut has been tightened twice. The correct
wheel nut tightness is 95 ft lbs (130 N·m). If in doubt
about the correct tightness, have them checked with a
torque wrench by your authorized dealer or at a service
station.
10. Lower the jack to it’s fully closed position.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
11. Secure the tire, jack, and tools in their proper loca-
tions. NOTE:
Tire should be stowed with the “beauty” side
up. Storing the tire upside down may result in scratching
or damage to the wheel face. Continue winching up the
tire until you hear the winch “ratchet” three times.
Double check to ensure the tire is snug against the
underbody of the vehicle. Damage to the winch cable
may result if the vehicle is driven with the tire loose.
WARNING!
Do not use power tools to winch the tire up or down.
Impact type tools may damage the winch mechanism.
12. Reinstall the rubber plug into the floor of the cargo
area.
