seated against the wheel.

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.

378

IN CASE OF EMERGENCY

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 under the passenger’s
front seat. There are remote terminals located under the
hood to assist in jump starting.

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.

NOTE:

Be sure that the disconnected cable ends do not

touch each other, or either vehicle, until properly con-
nected for jump starting.

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

sion into PARK and turn the ignition to OFF/LOCK.

2. Turn off the heater, radio, and all unnecessary electrical

accessories.

3. Remove the protective cover over the remote positive

(+)

battery post. Pull upward on the cover to remove it.

Remote Battery Posts

1 — Remote Positive (+) Post (covered with protective cap)
2 — Remote Negative (-) Post

IN CASE OF EMERGENCY

379

4. 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.

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 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 a few minutes, and then start
the engine in the vehicle with the discharged battery.

380

IN CASE OF EMERGENCY

CAUTION!

Do not run the booster vehicle engine above 2000 rpm
since it provides no charging benefit, wastes fuel and
can damage booster vehicle engine.

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 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 discharged
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.

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” in
this manual.

IN CASE OF EMERGENCY

381

IF YOUR ENGINE OVERHEATS

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

NEUTRAL, 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.

WARNING!

You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you

(Continued)

WARNING! (Continued)

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.

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.

MANUAL PARK RELEASE

WARNING!

Always secure your vehicle by fully applying the
parking brake before activating the Manual Park Re-
lease. In addition, you should be seated in the driver’s

(Continued)

382

IN CASE OF EMERGENCY

WARNING! (Continued)

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.

In order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery), a
Manual Park Release is available.

Follow these steps to use the Manual Park Release:

1. Firmly apply the parking brake.

2. Open the center console and locate the Manual Park

Release cover, remove it by snapping the cover away
from the console hinges.

3. Press and maintain firm pressure on the brake pedal.
