IN CASE OF EMERGENCY

CAUTION!

• When installing the power distribution center cover,

it is important to ensure the cover is properly posi-
tioned and fully latched. Failure to do so may allow
water to get into the power distribution center and
possibly result in an electrical system failure.

• When replacing a blown fuse, it is important to use

only a fuse having the correct amperage rating. The
use of a fuse with a rating other than indicated may
result in a dangerous electrical system overload. If a
properly rated fuse continues to blow, it indicates a
problem in the circuit that must be corrected.

JACKING AND TIRE CHANGING

WARNING!

• Do not attempt to change a tire on the side of the

vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

• Being under a jacked-up vehicle is dangerous. The

vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center
where it can be raised on a lift.

• Never start or run the engine while the vehicle is on

a jack.

• The jack is designed to be used as a tool for changing

tires only. The jack should not be used to lift the
vehicle for service purposes. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.

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
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 push or tow the vehicle in cases where the

transmission will not shift out of PARK (such as a dead

battery), a Manual Park Release is available.

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.

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 right rear of the

engine compartment, behind the Power Distribution Center.

NOTE:

The positive battery post is covered with a protec-

tive cap. Lift up on the cap to gain access to the post.

Positive Battery Post

IN CASE OF EMERGENCY

401

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.

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

sion into PARK (manual transmission in NEUTRAL)

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 cable’s 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.

402

IN CASE OF EMERGENCY

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 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 a few minutes, and then start

the engine in the vehicle with the discharged battery.

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 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 remote positive (+) post of the discharged

vehicle.

5. Reinstall the protective cover over the remote positive

(+)

post of the discharged vehicle.

IN CASE OF EMERGENCY

403

If frequent jump starting is required to start your vehicle

you should have the battery and charging system tested 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.

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, shift transmission into

NEUTRAL, but do not increase engine idle speed.

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.

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.

404

IN CASE OF EMERGENCY

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.

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. For vehicles with automatic transmission, push

and hold the lock button on the gear selector. Then, shift

back and forth between DRIVE and REVERSE (with auto-

matic transmission) or SECOND GEAR and REVERSE

(with manual transmission), while gently pressing the

accelerator. Use the least amount of accelerator pedal

pressure that will maintain the rocking motion, without

spinning the wheels or racing the engine.

NOTE:
• For vehicles with automatic transmission: Shifts be-

tween DRIVE and REVERSE can only be achieved at

wheel speeds of 5 mph (8 km/h) or less. Whenever the

transmission remains in NEUTRAL for more than 2

seconds, you must press the brake pedal to engage

DRIVE or REVERSE.

• Push the ⬙ESC Off⬙ switch to place the Electronic Stabil-

ity Control (ESC) system in

⬙Partial Off⬙ mode before

rocking the vehicle. Refer to “Electronic Brake Control

System” in “Safety” for further information. Once the

vehicle has been freed, push the

⬙ESC Off⬙ switch again

to restore

⬙ESC On⬙ mode.
