472 IN CASE OF EMERGENCY
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.
NOTE:
When using a portable battery booster pack, follow the
manufacturer's operating instructions and precautions.
Preparations For Jump Start
The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.
NOTE:
The positive battery post may be covered with a protective
cap if equipped. Lift up on the cap to gain access to the posi-
tive battery post. Do not jump off fuses. Only jump directly
off positive post which has a positive (+) symbol on or
around the post.
Positive Battery Post
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.

IN CASE OF EMERGENCY 473
1. Apply the parking brake, shift the automatic transmis-sion into PARK and turn the ignition OFF.
2. Turn off the heater, radio, and all unnecessary electrical accessories.
3. If using another vehicle to jump start the battery, park the vehicle within the jumper cables’ reach, apply the
parking brake and make sure the ignition is OFF.
Jump Starting Procedure
Connecting The Jumper Cables
Jumper Cable Connections
WARNING!
• Take care to avoid the radiator cooling fan whenever 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.
WARNING!
Do not allow vehicles to touch each other as this could
establish a ground connection and personal injury could
result.
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.

474 IN CASE OF EMERGENCY
1. Connect the positive (+) end of the jumper cable to the
positive (+) post of the discharged vehicle.
NOTE:
Do not jump off fuses. Only jump directly off positive
post.
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. 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 discharged
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.
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
personal injury. Only use the specific ground point, do
not use any other exposed metal parts.
CAUTION!
Do not connect jumper cable to any of the fuses on the
positive battery terminal. The resulting electrical current
will blow the fuse.

IN CASE OF EMERGENCY 475
If frequent jump starting is required to start your vehicle you
should have the battery and charging system inspected at an
authorized dealer.
IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the poten-
tial for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in NEUTRAL (N), but do not increase the engine idle speed
while preventing vehicle motion with the brakes. 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.
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.
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.6

476 IN CASE OF EMERGENCY
MANUAL PARK RELEASE
To push or tow the vehicle in cases where the transmission
will not shift out of PARK (P) (such as a dead battery), a
Manual Park Release is available.
Follow these steps to activate the Manual Park Release:
1. Apply firm pressure to the brake pedal while seated inthe driver’s seat.
2. Apply the parking brake if possible.
3. Using a small screwdriver or similar tool, remove the Manual Park Release cover, which is located to the lower
left of the steering column.
Manual Park Release Access Cover
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.
WARNING!
Always secure your vehicle by fully applying the
parking brake before activating the Manual Park
Release. In addition, you should be seated in the driver’s
seat with your foot firmly on the brake pedal when
activating the Manual Park Release. Activating the
Manual Park Release will allow your vehicle to roll away
if it is not secured by the parking brake, or by proper
connection to a tow vehicle. Activating the Manual Park
Release on an unsecured vehicle could lead to serious
injury or death for those in or around the vehicle.
