IN CASE OF EMERGENCY

333

REFUELING IN EMERGENCY

The vehicle is equipped with a refueling funnel for

a Cap-Less Fuel System, which is located with the

jack and tools

page 324. If refueling is

necessary, while using an approved gas can,

please insert the refueling funnel into the filler

neck opening.

NOTE:

In certain cold conditions, ice may prevent the fuel

door from opening. If this occurs, lightly push

around the perimeter of the fuel door to break the

ice buildup and re-release the fuel door by pushing

on the rear outer edge near the center to unlatch.

Do not pry on the door. In the case of a power loss

to the vehicle

page 194.

Refueling Funnel

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.
See below 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.
In any of the following situations, you can reduce

the potential for overheating by taking the

appropriate action.

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.

334

IN CASE OF EMERGENCY



On the highways — slow down.



In city traffic — while stopped, place the trans

mission in NEUTRAL (N).

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.

MANUAL PARK RELEASE

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.
Follow These Steps To Activate The Manual Park

Release:
1. Apply firm pressure to the brake pedal while

seated in the driver’s seat.

2. Apply the parking brake, if possible.

Manual Park Release Location

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), as soon as it’s safe, 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!

You should be seated in the driver’s seat with

your foot firmly placed on the brake pedal to

maintain control of the vehicle before activating

the Manual Park Release. If possible, you should

apply the parking brake. Activating the Manual

Park Release will allow your vehicle to roll away if

it is not secured or properly connected 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 CASE OF EMERGENCY

3. Using a flathead screwdriver or similar tool,

remove the Manual Park Release access

cover, which is to the lower left of the steering

column, below the park brake switch.

Access Cover

4. To unlock handle, insert a flathead screwdriver

or similar tool into the lock release, rotate a

quarter turn counterclockwise and hold

simultaneously pulling on the tether strap.

Lock Release

5. Pull the tether strap out as far as it will go, then

release it. The transmission should now be in

NEUTRAL (N), allowing the vehicle to be

moved.

Tether Strap

6. Release the parking brake only when the

vehicle is securely connected to a tow vehicle.

To Reset The Manual Park Release:
1. Apply firm pressure to the brake pedal while

seated in the driver’s seat.

2. Pull the tether strap out again, then release it.
3. Allow the tether to retract with the lever back

to its original position.

4. Verify that the transmission is in PARK (P).
5. Confirm that the tether has retracted fully and

re-install the access cover. If the access cover

cannot be re-installed, repeat steps 1 through 4.

Tether Reinstalled

336

IN CASE OF EMERGENCY

NOTE:

When the lever is locked in the released position,

the tether will remain outside of the trim panel and

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. 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 265.

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 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).

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.



Crosshatched zone marked with dimples at the

MIN and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch

markings on the dipstick.
Adding 1 quart (1 liter) of oil when the reading is at

the low end of the dipstick range will raise the oil

level to the high end of the range marking.

The fluid reservoir for the windshield washers and

the rear window washer is shared. The fluid

reservoir is located in the engine compartment, be

sure to check the fluid level at regular intervals. Fill

the reservoir with windshield washer solvent only

(not radiator antifreeze). When refilling the washer

fluid reservoir, take some washer fluid and apply it

to a cloth or towel and wipe clean the wiper blades,

this will help blade performance. To prevent

freeze-up of your windshield washer system in cold

weather, select a solution or mixture that meets or

exceeds the temperature range of your climate.
