7. 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 sta-
bility.
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.
8. Remove the lug nuts and wheel.
9. 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.
CAUTION!
Be sure to mount the spare tire with the valve stem
facing outward. The vehicle could be damaged if the
spare tire is mounted incorrectly.

JUMP-STARTING
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.
WARNING!
Do not attempt jump-starting if the battery is frozen.
It could rupture or explode and cause personal injury.
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.
514 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 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.
NOTE:Be sure that the disconnected ends of the cables
do not touch while still connected to the other vehicle.
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. Remove the protective cover over the remote positive
(+)battery post. Pull upward on the cover to remove
it.
4. 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 jump-starting procedure could
result in personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
NOTE:Make sure at all times that unused ends of
jumper cables are not contacting each other or either
vehicle while making connections.Connecting The Jumper Cables
1. Connect the positive(+)end of the jumper cable to the
remote 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 the remote negative(-)post of the vehicle with
the discharged battery.
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

in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative(-)end of the jumper cable
from the remote negative(-)post of the discharged
vehicle.
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 remote positive(+)post of the dis-
charged vehicle.
5. Reinstall the protective cover over the remote positive
(+)post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system tested
at your authorized dealer.
