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, shift the transmission
to NEUTRAL, but do not increase the engine idle
speed.
346 WHAT TO DO IN EMERGENCIES

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.
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 maximum
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.
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 try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.

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 be used 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 scissor-type jack and tire changing tools are located
in the passenger side compartment, behind the second
row seat.

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.
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 you to pull the tire out from under the vehicle.
