hicle. Always stow the jack parts and the spare tire in
the places provided.
JUMP-STARTING PROCEDURES
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
NOTE:When using a portable battery booster pack
follow the manufacturer ’s operating instructions and
precautions.

WHAT TO DO IN EMERGENCIES 491

CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter motor,
alternator or electrical system may occur.
WARNING!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
Preparations For Jump-Start
The battery in your vehicle is located in the right rear of
the engine compartment, behind the Power Distribution
Center.

492 WHAT TO DO IN EMERGENCIES

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 watch bands or
bracelets that might 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 and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories. 3. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in per-
sonal injury or property damage due to battery ex-
plosion.

WHAT TO DO IN EMERGENCIES 493

CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
1. Connect the positive (+)end of the jumper cable to the
positive (+)post of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative end (-)of the jumper cable to the
negative (-)post of the booster battery.
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 cable to the negative post (-) of the
discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury.
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.
Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-)jumper cable from the
engine ground of the vehicle with the discharged battery.
7. Disconnect the negative end (-)of the jumper cable
from the negative (-)post of the booster battery.
494 WHAT TO DO IN EMERGENCIES

8. Disconnect the opposite end of the positive(+)jumper
cable from the positive (+)post of the booster battery.
9. Disconnect the positive (+)end of the jumper cable
from the positive (+)post of the discharged vehicle.
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 that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, 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 by a rocking motion. Turn your
steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE/
1st gear and REVERSE. Using minimal accelerator pedal
pressure to maintain the rocking motion, without spin-
ning the wheels, is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.6
WHAT TO DO IN EMERGENCIES 495

NOTE:If your vehicle is equipped with Traction Con-
trol or Electronic Stability Control (ESC), turn the system
OFF before attempting to “rock” the vehicle.
CAUTION!
•When “rocking” a stuck vehicle by moving be-
tween DRIVE/1st gear and REVERSE, do not spin
the wheels faster than 15 mph (24 km/h), or drive-
train damage may result.
•Revving the engine or spinning the wheels too fast
may lead to transmission overheating and failure.
It can also damage the tires. Do not spin the
wheels above 30 mph (48 km/h) while in gear (no
transmission shifting occurring).
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated by excessive wheel speeds may cause damage, or
even failure, of the axle and tires. A tire could
explode and injure someone. Do not spin your vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping when you are stuck and do not let anyone near
a spinning wheel, no matter what the speed.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, they are
mounted in the front and the rear.
NOTE: For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.
496 WHAT TO DO IN EMERGENCIES

WARNING!
•Chains are not recommended for freeing a stuck
vehicle. Chains may break, causing serious injury
or death.
•Stand clear of vehicles when pulling with tow
hooks. Tow straps may become disengaged, caus-
ing serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle. Tow straps are recommended
when towing the vehicle, chains may cause vehicle
damage.
SHIFT LEVER OVERRIDE
If a malfunction occurs and the shift lever cannot be
moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Firmly set the parking brake.
2. Turn the ignition to the ON/RUN position without
starting the engine.
