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.

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.

322

IN CASE OF EMERGENCY

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 build up. Re-release the fuel door by pushing on

the rear outer edge near the center to unlatch. 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.
See the following steps for refueling:
1. Retrieve funnel from under the rear cargo

load floor.

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.

6. Close the fuel door making sure the latch is

engaged by pushing on the rear outer edge

near the center.

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.

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

323

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

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.
To activate the Manual Park Release, see the

following steps:
1. Apply firm pressure to the brake pedal while

seated in the driver’s seat.

2. Apply the Electric Park Brake (EPB), if possible.
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.

Manual Park Release Access Cover

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 conditioner 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

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.

324

IN CASE OF EMERGENCY

NOTE:

Insert the flathead screwdriver or similar tool in the

lower notch of the access cover and gently rotate

clockwise to remove.

4. Unlock the orange lock plug by turning it a

quarter turn counterclockwise.

Locked — Unlocked Position

5. Pull the lock plug out as far as it will go, then

release it. The transmission should now be in

NEUTRAL (N), allowing the vehicle to be

moved.

NOTE:

When the lever is locked in the released position,

the lock plug and tether will remain outside of the

trim panel and the access cover cannot be rein

stalled.
6. Release the EPB 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 lock plug 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).

cannot be reinstalled, repeat steps 1

through 4.

IN CASE OF EMERGENCY

325

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. 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 251.

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).

326

IN CASE OF EMERGENCY

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 on

page 195.

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.
