CAUTION!
To prevent damage to the starter, do not continuously
crank the engine for more than 10 seconds at a time.
Wait 10 to 15 seconds before trying again.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
(Continued)
WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
•If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
474 STARTING AND OPERATING

3. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
4. Finish tightening the wheel bolts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the wheel bolts in a star pattern until
each wheel bolt has been tightened twice. Refer to
“Torque Specifications” in this section for the proper
lug bolt torque. If in doubt about the correct tightness,
have them checked with a torque wrench by your
authorized dealer or service station.
5. Lower the jack until it is free. Remove the wheel
chocks. Reassemble the lug wrench to the jack assem-
bly and stow it in the spare tire area. Secure the
assembly using the means provided. Release the park-
ing brake before driving the vehicle.
6. After 25 miles (40 km) check the wheel bolt torque
with a torque wrench to ensure that all wheel bolts are
properly seated against the wheel.
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.
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.
640 WHAT TO DO IN EMERGENCIES

CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
Connecting The Jumper Cables
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 jumper cable to the negative (-)
post of the discharged battery. The resulting electri-
cal spark could cause the battery to explode and
could result in personal 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
WHAT TO DO IN EMERGENCIES 643

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.
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 phones, 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. Press and hold the lock button on the shift
lever. Then shift back and forth between DRIVE and
REVERSE, while gently pressing the accelerator.
644 WHAT TO DO IN EMERGENCIES

WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin, or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water. Refer to
“Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.
•Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.
•Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.
CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked positive
(+) and negative (-) and are identified on the
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion.
•If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables be-
fore connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
