IN CASE OF EMERGENCY

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

discharged vehicle.

5. Reinstall the protective cover over the positive (+)

post of the discharged vehicle.

NOTE:

If frequent jump starting is required to start your vehicle

you should have the battery and charging system tested at

an authorized dealer.

IF YOUR ENGINE OVERHEATS

If the vehicle is overheating, it will need to be serviced by

an authorized dealer.
Potential signs of vehicle overheating:



Temperature gauge is at HOT (H)



Strong smell of coolant



White smoke coming from engine or exhaust



Coolant bottle coolant has bubbles present

In the event it is observed that the temperature gauge is

moving towards or close to the HOT (H) position, 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 (N), but do not increase the engine idle speed

while preventing vehicle motion with the brakes.



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 supple

ment to the radiator and aids in removing heat from the

engine cooling system.

CAUTION!

Make sure at all times that unused ends of jumper

cables are not contacting each other or either vehicle

while making connections. Failure to follow these

procedures could result in damage to the charging

system of the booster vehicle or the discharged vehicle.

CAUTION!

Do not run the booster vehicle engine above 2,000 RPM

since it provides no charging benefit, wastes fuel, and

can damage booster vehicle engine.

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.

IN CASE OF EMERGENCY

301

MANUAL PARK RELEASE

In order to move the vehicle in cases where the

transmission will not shift out of PARK (P) (such as a

depleted battery), a Manual Park Release is available.

See the following steps to use the Manual Park Release:
1. Firmly apply the parking brake.
2. Using a small screwdriver or similar tool, remove the

manual park release cover located in front of the gear

selector, to access the release tether strap.

Manual Park Release Cover

3. Fish the tether strap up through the opening in the

console base.

Tether Strap

4. Press and maintain firm pressure on the brake pedal.
5. Pull the tether strap up until the release lever locks

into place in the vertical position. The vehicle is now

out of PARK (P) and can be moved. Release the

parking brake only when the vehicle is securely

connected to a tow vehicle.

Vertical Released Position

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 condi

tioner 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 immedi

ately 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.

302

IN CASE OF EMERGENCY

To Reset The Manual Park Release:
1. Pull upward on the tether strap, releasing it from the

“locked” position.

2. Lower the Manual Park Release lever downward and

to the left, into its original position.

Original Tether Position

3. Tuck the tether strap into the base of the console,

and reinstall the cover.

NOTE:

When the lever is locked in the release position the access

cover cannot be reinstalled.

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 (D) and REVERSE (R) (with

automatic transmission) or SECOND (2) gear and

REVERSE (R) (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

between DRIVE (D) and REVERSE (R) can only be

achieved at wheel speeds of 5 mph (8 km/h) or less.

Whenever the transmission remains in NEUTRAL (N)

for more than two seconds, you must press the brake

pedal to engage DRIVE (D) or REVERSE (R).



Push the ESC OFF button to place the Electronic

Stability Control (ESC) system in “Partial OFF” mode,

before rocking the vehicle

page 246. Once the

vehicle has been freed, push the ESC OFF button again

to restore “ESC On” mode.

WARNING!

Fast spinning tires can be dangerous. Forces generated

by excessive wheel speeds may cause damage, or even

failure, of the axle and tires. A tire could explode and

injure someone. Do not spin your vehicle's wheels

faster than 30 mph (48 km/h) or for longer than

30 seconds continuously without stopping when you

are stuck and do not let anyone near a spinning wheel,

no matter what the speed.

CAUTION!



Racing the engine or spinning the wheels may lead to

transmission overheating and failure. Allow the

engine to idle with the transmission in NEUTRAL for

at least one minute after every five rocking-motion

cycles. This will minimize overheating and reduce the

risk of clutch or transmission failure during

prolonged efforts to free a stuck vehicle.



When “rocking” a stuck vehicle by shifting between

DRIVE/SECOND gear and REVERSE, do not spin the

wheels faster than 15 mph (24 km/h), or drivetrain

damage may result.



Revving the engine or spinning the wheels too fast

may lead to transmission overheating and failure. It

can also damage the tires. Do not spin the wheels

above 30 mph (48 km/h) while in gear (no transmis

sion shifting occurring).

IN CASE OF EMERGENCY

303

TOWING A DISABLED VEHICLE

This section describes procedures for towing a disabled vehicle using a commercial towing service.
If the transmission and drivetrain are operable, disabled 4x4 vehicles may also be towed as described

page 176.

Proper towing or lifting equipment is required to prevent

damage to your vehicle. Use only tow bars and other

equipment designed for this purpose, following equipment

manufacturer’s instructions. Use of safety chains is

mandatory. Attach a tow bar or other towing device to

main structural members of the vehicle, not to fascia/

bumpers or associated brackets. State and local laws

regarding vehicles under tow must be observed.
If you must use the accessories (wipers, defrosters, etc.)

while being towed, the ignition must be in the ON/RUN

position, not the ACC position.
If the vehicle's battery is discharged, instructions on

shifting the automatic transmission out of PARK (P) in

order to move the vehicle
