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.

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.

432

IN CASE OF EMERGENCY

Preparations For Jump Start

The battery in your vehicle is located in the front of the
engine compartment, behind the left headlight assembly.

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.

(Continued)

WARNING! (Continued)

• 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. Apply the parking brake, shift the automatic transmis-

sion into PARK and turn the ignition to LOCK.

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.

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.

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 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.

5. Start the engine in the vehicle that has the booster

battery, let the engine idle for 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.

434

IN CASE OF EMERGENCY

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 an 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.

REFUELING IN EMERGENCY

The funnel for the Cap-Less Fuel System is located in the
spare tire storage area. If your vehicle is out of fuel and an
auxiliary fuel can is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.

For more information on the Cap-Less Fuel System refer to
“Refueling The Vehicle” in “Starting And Operating”.

IF YOUR ENGINE OVERHEATS

In any of the following situations, you can reduce the
potential for overheating your engine by taking the appro-
priate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in

NEUTRAL, but do not increase engine idle speed.

CAUTION!

Driving with a hot cooling system could damage your
vehicle. If the temperature gauge reads “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 the
“H” and you hear continuous chimes, turn the engine
off immediately and call for service.

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.
