202IN CASE OF EMERGENCY
If frequent jump starting is required to start your vehicle,
you should have the battery and charging system
inspected at an authorized dealer.
REFUELING IN EMERGENCY – IF EQUIPPED
The vehicle is equipped with a refueling funnel for a
Cap-Less Fuel System, which can be found under the load
floor in the rear cargo area. 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.

Fuel Funnel Location
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. 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 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.
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.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 Malfunction 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 EMERGENCY203
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.
GEAR SELECTOR OVERRIDE
If a malfunction occurs and the gear selector cannot be
moved out of the PARK (P) position, you can use the
following procedure to temporarily move the gear selector:

1. Turn the engine OFF.

2. Apply the parking brake.
3. Using a screwdriver or similar tool, carefully separate the shifter bezel and boot assembly from the center
console, and raise it up to access the gear selector
mechanism.

Shifter Bezel/Boot

4. Press and maintain firm pressure on the brake pedal.
5. Insert a small screwdriver or similar tool down into the gear selector override access hole (at the right
front corner of the gear selector assembly), and push
and hold the override release lever down.

Override Access Hole

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 “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.

204IN CASE OF EMERGENCY
6. Move the gear selector to the NEUTRAL (N) position.
7. The vehicle may then be started in NEUTRAL (N).
8. Reinstall the gear selector boot.
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 (if necessary), to place the Elec
-
tronic Stability Control (ESC) system in “Partial Off” mode,
before rocking the vehicle
Úpage 145. 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 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).

ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced Accident
Response System.
This feature is a communication network that takes effect
in the event of an impact. Detailed information can be
found on
Úpage 175.
EVENT DATA RECORDER (EDR)
This vehicle is equipped with an event data recorder
(EDR). The main purpose of an EDR is to record data that
will assist in understanding how a vehicle’s systems
performed under certain crash or near crash-like
situations, such as an air bag deployment or hitting a road
obstacle. Detailed information can be found on
Úpage 176.
WARNING!
Do not use a chain for freeing a stuck vehicle. Chains
may break, causing serious injury or death.
 Stand clear of vehicles when pulling with tow hooks.
Tow straps may become disengaged, causing
serious injury.
CAUTION!
Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for tow
truck hookup or highway towing. You could damage your
vehicle.
WARNING!
Recovery straps should only be used in emergencies to
rescue stranded vehicles. Only use Recovery straps on
vehicles that fit within the recommended Gross Vehicle
Weight (GVW) of your recovery strap. Only attach
recovery straps to OE recommended anchor points or
emergency towing anchor points. Never attach to tow
ball or vehicle tie down point, these are not designed
for this purpose. Never attach to vehicle steering, drive
train, or any other suspension components. NEVER pull
a strap over sharp edges or abrasive surfaces that can
damage the recovery strap. NEVER use a damaged
strap, it has reduced strength. DO NOT attempt to
repair straps. ONLY persons involved in the recovery

214SERVICING AND MAINTENANCE
CHECKING OIL LEVEL
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.
NOTE:Use care when filling under hood fluids such as Engine Oil,
Windshield Washer Solvent, Antifreeze etc. to minimize
spillage onto top of engine. Any excess fluid that is spilled
onto the top of the engine should be removed using
compressed air or absorbent cloth.
Adding 1 qt (1 L) 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.
ADDING WASHER FLUID
The windshield and rear window washers share the same
fluid reservoir. The fluid reservoir is located in the front of
the engine compartment. Be sure to check the fluid level
in the reservoir at regular intervals. Fill the reservoir with
windshield washer solvent (not radiator antifreeze) and
operate the system for a few seconds to flush out the
residual water.
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. This rating
information can be found on most washer fluid containers.
NOTE:Use care when filling under hood fluids such as Engine Oil,
Windshield Washer Solvent, Antifreeze etc. to minimize
spillage onto top of engine. Any excess fluid that is spilled
onto the top of the engine should be removed using
compressed air or absorbent cloth.
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, and periodic
maintenance is not required.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
WARNING!
Commercially available windshield washer solvents are
flammable. They could ignite and burn you. Care must
be exercised when filling or working around the washer
solution.
WARNING!
Battery fluid is a corrosive acid solution and can burn
or even blind you. Do not allow battery fluid to
contact your eyes, skin, or clothing. Do not lean over
a battery when attaching clamps. If acid splashes in
eyes or on skin, flush the area immediately with large
amounts of water
Úpage 200.
 Battery gas is flammable and explosive. Keep flame
or sparks away from the battery. Do not use a
booster battery or any other booster source with an
output greater than 12 Volts. Do not allow cable
clamps to touch each other.
 Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands after
handling.

Materials Added To Engine Oil
The manufacturer strongly recommends against the
addition of any additives (other than leak detection dyes)
to the engine oil. Engine oil is an engineered product and
its performance may be impaired by supplemental
additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact an authorized dealer, service
station or governmental agency for advice on how and
where used oil and oil filters can be safely discarded in
your area.
CAUTION!
It is essential when replacing the cables on the
battery that the positive cable is attached to the posi -
tive post and the negative cable is attached to the
negative post. Battery posts are marked positive (+)
and negative (-) and are identified on the battery
case. Cable clamps should be tight on the terminal
posts and free of corrosion.
 If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables
before connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
CAUTION!
Precautions have been taken to safeguard all parts and
connections however, the pressures generated by these
machines is such that complete protection against
water ingress cannot be guaranteed.

ACCESSORY DRIVE BELT INSPECTION
When inspecting accessory drive belts, small cracks that
run across ribbed surface of belt from rib to rib, are
considered normal. These are not a reason to replace belt.
However, cracks running along a rib (not across) are not
normal. Any belt with cracks running along a rib must be
replaced. Also have the belt replaced if it has excessive
wear, frayed cords or severe glazing.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:
Rib chunking (one or more ribs has separated from belt
body)
 Rib or belt wear
 Longitudinal belt cracking (cracks between two ribs)
 Belt slips
 Groove jumping (belt does not maintain correct posi -
tion on pulley) 
Belt broken (identify and correct problem before new
belt is installed)
 Noise (objectionable squeal, squeak, or rumble is
heard or felt while drive belt is in operation)
Some conditions can be caused by a faulty component
such as a belt pulley. Belt pulleys should be carefully
inspected for damage and proper alignment.
Belt replacement on some models requires the use of
special tools; we recommend having your vehicle serviced
at an authorized dealer.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
