HAZARD WARNING FLASHERS
The Hazard Warning flasher switch is located on the
instrument panel below the climate controls.Push the switch to turn on the Hazard Warning
flasher. When the switch is activated, all direc-
tional turn signals will flash on and off to warn oncoming
traffic of an emergency. Push the switch a second time to
turn off the Hazard Warning flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
Hazard Warning flashers will continue to operate even
though the ignition is placed in the OFF position.
NOTE: With extended use the Hazard Warning flashers
may wear down your battery.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, shift transmission into
NEUTRAL, but do not increase 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.
570 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 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.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

WARNING!(Continued)
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.
• Never start or run the engine while the vehicle is
on a jack.
• 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 jack and lug wrench are located in the rear storage
compartment. NOTE:
Turn the black plastic wing nut counterclockwise
to loosen the jack from the storage bin.

4. Shift the automatic transmission into PARK, or amanual transmission into REVERSE.
5. Turn the ignition to LOCK.
6. Block both the front and rear of the wheel diagonally opposite of the jacking position. For ex-
ample, 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.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
• Never start or run the engine with the vehicle on a
jack.

Preparations For Jump-Start
The battery in your vehicle is located in the right rear of
the engine compartment, behind the Power Distribution
Center.
WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by
moving fan blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission into PARK (manual transmission in NEUTRAL) and
turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri- cal accessories.
Positive Battery Post
582 WHAT TO DO IN EMERGENCIES

4. Connect the opposite end of the negative(-)jumper
cable to a good engine ground (exposed metal part of
the discharged vehicle’s engine) away from the battery
and the fuel injection system.
WARNING!
Do not connect the jumper cable to the negative (-) post
of the discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
serious injury. Only use the specific ground point, do
not use any other exposed metal parts.
5. Start the engine in the vehicle that has the booster battery, let the engine idle a few minutes, and then
start the engine in the vehicle with the discharged
battery. 6. Once the engine is started, remove the jumper cables
in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative (-)end of the jumper cable
from the engine ground of the vehicle with the dis-
charged battery.
2. Disconnect the opposite end of the negative (-)jumper
cable from the negative (-)post of the booster battery.
3. Disconnect the positive (+)end of the jumper cable
from the positive (+)post of the booster battery.
4. Disconnect the opposite end of the positive (+)jumper
cable from the positive (+)post of the vehicle with the
discharged battery.
584 WHAT TO DO IN EMERGENCIES

If frequent jump starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories plugged into the vehicle power outlets
draw power from the vehicle’s battery, even when not
in use (i.e., cellular devices, etc.). Eventually, if
plugged in long enough without engine operation,
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it
can often be moved using a rocking motion. Turn the
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVEand REVERSE (with automatic transmission) or 2nd gear
and REVERSE (with manual transmission), while gently
pressing the accelerator. Use the least amount of accel-
erator pedal pressure that will maintain the rocking
motion, without spinning the wheels, or racing the
engine.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the transmission in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of clutch or transmission failure during
prolonged efforts to free a stuck vehicle.6
