IN CASE OF EMERGENCY

REFUELING IN EMERGENCY

The vehicle is equipped with a refueling funnel

page 242 for a Cap-Less Fuel System. If

refueling is necessary, while using an approved

gas can, insert the refueling funnel into the filler

neck opening. Take care to open both flappers with

the funnel to avoid spills.

NOTE:

In certain cold conditions, ice may prevent the fuel

door from opening. If this occurs, lightly push on

the fuel door to break the ice buildup and

re-release the fuel door using the inside release

button. Do not pry on the door.
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors. A

funnel is provided to allow emergency refueling

with a gas can.

Refueling Funnel

See the following steps for refueling:
1. Retrieve funnel from the spare tire storage

area.

2. Insert funnel into same filler pipe opening as

the fuel nozzle.

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper

doors open.

4. Pour fuel into funnel opening.

5. Remove funnel from filler pipe, clean off prior

to putting back in the spare tire storage area.

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

CAUTION!

To avoid fuel spillage and overfilling, do not “top

off” the fuel tank after filling.

WARNING!



Never have any smoking materials lit in or

near the vehicle when the fuel door is open or

the tank is being filled.



Never add fuel when the engine is running.

This is in violation of most state and federal

fire regulations and may cause the Malfunc

tion Indicator Light to turn on.



A fire may result if fuel is pumped into a

portable container that is inside of a vehicle.

You could be burned. Always place fuel

containers on the ground while filling.

IN CASE OF EMERGENCY

251

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 trans

mission 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 supplement to the radiator and

aids in removing heat from the engine cooling

system.

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. Open the center console and locate the

Manual Park Release cover, remove it by

snapping the cover away from the console

hinges.

Manual Park Release Cover

3. Press and maintain firm pressure on the brake

pedal.

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.

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.

252

IN CASE OF EMERGENCY

4. Using a screwdriver or similar tool, push the

metal latch in towards the tether strap.

Releasing Latch

5. While the metal latch is in the open position,

pull upward on the tether strap until the lever

clicks and latches in the released position. The

transmission is now out of PARK (P) and the

vehicle can be moved.

Released Position

NOTE:

To prevent the vehicle from rolling unintentionally,

firmly apply the parking brake.

To Disengage The Manual Park Release Lever:
1. To disengage the Manual Park Release, apply

tension upward while pushing the release

latch towards the tether to unlock the lever.

Disengaging The Lever

2. Once the tension has been released and the

lever has been unlocked, be sure it is stowed

properly and locks into it’s original position.

NOTE:

Be sure to replace the cover by snapping it back in

place.

CAUTION!

Closing the armrest while the Manual Park

Release is activated may damage the Manual

Park Release mechanism, the transmission,

and/or the armrest.

IN CASE OF EMERGENCY

(Continued)

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. Push and

hold the lock button on the gear selector. Then,

shift back and forth between DRIVE (D) and

REVERSE (R) while gently pressing the accelerator.

NOTE:

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).
Use the least amount of accelerator pedal

pressure that will maintain the rocking motion

without spinning the wheels or racing the engine.

NOTE:

Push the ESC OFF button to place the Electronic

Stability Control (ESC) system in “Partial Off”

mode, before rocking the vehicle

page 189.

Once the vehicle has been freed, push the ESC OFF

button again to restore ESC On mode.

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 vehicles may also be towed as

described on

page 146.

NOTE:

Vehicles equipped with Quadra-Lift must be placed

in Transport mode, before tying them down (from

the body) on a trailer or flatbed truck

page 152.

If the vehicle cannot be placed in Transport mode

(for example, engine will not run), tie-downs should

be fastened over the tires using specific tire

tie-down nets. Failure to follow these instructions

may cause fault codes to be set and/or cause loss

of proper tie-down tension.

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 transmis

sion failure during prolonged efforts to free a

stuck vehicle.



When “rocking” a stuck vehicle by shifting

between DRIVE 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 transmission shifting occur

ring).

CAUTION!

254

IN CASE OF EMERGENCY

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

To ensure proper engine lubrication, the engine oil

must be maintained at the correct level. Check the

oil level at regular intervals, such as every fuel

stop. The best time to check the engine oil level is

about five minutes after a fully warmed up engine

is shut off.
Checking the oil while the vehicle is on level ground

will improve the accuracy of the oil level readings.
There are four possible dipstick types:



Crosshatched zone.



Crosshatched zone marked SAFE.



Crosshatched zone marked with MIN at the low

end of the range and MAX at the high end of the

range.
