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
and REVERSE, while gently pressing the ac-
celerator. 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 and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmis-
sion remains in NEUTRAL for more than
2 seconds, you must press the brake pedal
to engage DRIVE or REVERSE.
• Push the "ESC Off" switch, to place the
Electronic Stability Control (ESC) system in
"Partial Off" mode, before rocking the ve-
hicle. Refer to “Electronic Brake Control
System” in “Safety” in your Owner’s
Manual for further details. Once the vehicle
has been freed, push the "ESC Off" switch
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 ve-
hicle's wheels faster than 30 mph
(48 km/h) or for longer than 30 seconds
continuously without stopping when you
WARNING!
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 over-
heating 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 mini-
mize overheating and reduce the risk of
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
• When “rocking” a stuck vehicle by shift-
ing 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 dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
201

If the vehicle's battery is discharged, refer to
"Manual Park Release" in this section for
instructions on shifting the automatic trans-
mission out of PARK in order to move the
vehicle.
CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
• When securing the vehicle to a flatbed
truck, do not attach to front or rear
suspension components. Damage to
your vehicle may result from improper
towing.
• If the vehicle being towed requires steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the OFF
mode.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the OFF mode.
The only approved method of towing without
the key fob is with a flatbed truck. Proper
towing equipment is necessary to prevent
damage to the vehicle.
Four–Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods are to tow the vehicle on a flatbed or with
one end of the vehicle raised and the opposite
end on a towing dolly.
If flatbed equipment is not available and the
transfer case is operable, the vehicle may be
towed (in the forward direction, withALL
wheels on the ground),IFthe transfer case is
inNEUTRAL(N) and the transmission is in
PARK. Refer to “Recreational Towing” in
“Starting And Operating” for detailed
instructions.
CAUTION!
• Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
mission or transfer case will occur if a
front or rear wheel lift is used when
towing.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-

age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
Tow Eye Usage
Your vehicle is equipped with a tow eye that
can be used to move a disabled vehicle.
When using a tow eye be sure to follow the
“Tow Eye Usage Precautions” and the “Tow-
ing A Disabled Vehicle” instructions in this
section.
The tow eyes are mounted below the front and
rear bumpers.
Tow Eye Usage Precautions
WARNING!
Stand clear of vehicles when pulling with
tow eyes.
• Do not use a chain with a tow eye.
Chains may break, causing serious injury
or death.
203

WARNING!
• Do not use a tow strap with a tow eye.
Tow straps may break or become disen-
gaged, causing serious injury or death.
• Failure to follow proper tow eye usage
may cause components to break result-
ing in serious injury or death.
• The brake and steering power assist sys-
tems will not function while the vehicle
is being towed. You will, therefore, need
to apply more force on the brake pedal
and steering wheel. Do not use flexible
ropes when towing, and avoid jerky
movements. Do not start the engine
while towing the car. Before tightening
the ring, clean the threaded housing
thoroughly. Make sure that the ring is
fully screwed into the housing before
towing the car.
CAUTION!
• The tow eye must only be used for road-
side emergencies. Use with an appropri-
ate device in accordance with highway
code (a rigid bar) to maneuver the ve-
hicle in preparation for transport via a
tow truck.
• The tow eye must not be used to move
the vehicle off the road or where there
are obstacles.
• Do not use the tow eyes for tow truck
hookup or highway towing.
• Do not use the tow eye to free a stuck
vehicle. Refer to the “Freeing A Stuck
Vehicle” section for further information.
• Please refer to the “Towing A Disabled
Vehicle” section for detailed instruc-
tions. Damage to your vehicle may occur
if these guidelines are not followed.NOTE:
• Ensure that the tow eye is properly
mounted.

WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.

Scheduled Servicing — Diesel Engine
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for engine oil
replacement.
On vehicles equipped with instrument cluster
display, “Oil Change Required” will be dis-
played and a single chime will sound, indi-
cating that an oil change is necessary.
On non-instrument cluster display equipped
vehicles, “Change Oil” will flash in the instru-
ment cluster odometer and a single chime
will sound, indicating that an oil change is
necessary.Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed. Severe Operating Conditions can
cause the change oil message to illuminate
as earlier than specified. Have your vehicle
serviced as soon as possible, within the next
500 miles (805 km).
NOTE:
•The actual interval for changing engine oil
and replacing the engine oil filter depends on
the vehicle usage conditions, and is signaled
by the warning light or message in the instru-
ment cluster. In any case, it must never ex-
ceed two years. If the vehicle is used mainly
for city driving, change the engine oil and
filter every year.

Checking Oil Level — Gasoline Engine
WARNING!
• Never smoke while working in the engine
compartment: gas and inflammable va-
pors may be present, with the risk of fire.
• Be very careful when working in the
engine compartment when the engine is
hot: you may get burned. Do not get too
close to the radiator cooling fan: the
electric fan may start; danger of injury.
Scarves, ties and other loose clothing
might be pulled by moving parts.
CAUTION!
• Be careful not to confuse the various
types of fluids while topping up: they are
not compatible with each other! Topping
up with an unsuitable fluid could se-
verely damage your car.
• The oil level must never exceed the MAX
mark.
• Always top up using engine oil of the
same specifications as that already in
the engine.
CAUTION!
• If the engine oil is being topped up, wait
for the engine to cool down before loos-
ening the filler cap, particularly for ve-
hicles with aluminium cap (if
equipped). WARNING: risk of burns!
• Overfilling or underfilling the crankcase
will cause aeration or loss of oil pres-
sure. This could damage your engine.
To ensure proper lubrication of your vehicle's
engine, the engine oil must be maintained at
the correct level. The engine oil level should
be checked five minutes after a warmed up
engine has been shut off.
Checking the oil while the vehicle is on level
ground will improve the accuracy of the oil
level readings. Always maintain the oil level
within the SAFE zone on the dipstick. Adding
1 quart (0.95 liters) of oil when the reading is
at the bottom of the crosshatch zone will
result in a reading at the top of the cross-
hatch zone on these engines.
Adding Washer Fluid
The fluid reservoir for the windshield washers
and the rear window washer (if equipped) is
shared. The fluid reservoir is located in the
engine compartment. Be sure to check the
fluid level at regular intervals. Fill the reser-
voir 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 perfor-
mance.
To prevent freeze-up of your windshield
washer system in cold weather, select a solu-
tion or mixture that meets or exceeds the
temperature range of your climate. This rat-
ing information can be found on most washer
fluid containers.
WARNING!
Commercial windshield washer solvents
are flammable. They could ignite and burn
you. Care must be exercised when filling or
working around the washer solution.

Maintenance-Free Battery
Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Using the battery with low fluid will
irreparably damage the battery and may
cause an explosion.
• When performing any operation on the
battery or near it, always protect your
eyes with special goggles.
• Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an autho-
rized dealership.
• 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. Refer to “Jump Starting Proce-
WARNING!
dure” in “In Case Of Emergency” for
further information.
• 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 ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
CAUTION!
• It is essential when replacing the cables
on the battery that the positive cable is
attached to the positive post and the
negative cable is attached to the nega-
tive post. Battery posts are marked posi-
tive (+) and negative (-) and are identi-
fied 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

Windshield Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner.
This will remove accumulations of salt or road
film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to remove frost
or ice from the windshield. Keep the blade
rubber out of contact with petroleum prod-
ucts such as engine oil, gasoline, etc.NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with
a new unit. Do not attempt to repair a wiper
arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade
in place or the glass may be damaged.
1. Lift the wiper arm to raise the wiper blade
off of the glass, until the wiper arm is in
the full up position.

Cooling System
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 open a cooling
system pressure cap when the radiator
or coolant bottle is hot.
• Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
WARNING!
• When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
Coolant Checks
Check the engine and, intercooler (if
equipped) coolant (antifreeze) protection ev-
ery 12 months (before the onset of freezing
weather, where applicable). If the engine
and, intercooler (if equipped) is dirty or rusty
in appearance, the system should be drained,
flushed and refilled with fresh OAT coolant
(conforming to MS.90032) by an authorized
dealer. Check the front of the A/C condenser
(if equipped) or radiator for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the A/C condenser (if
equipped) or the back of the radiator core.
Check the engine and, intercooler (if
equipped) cooling system hoses for brittle
rubber, cracking, tears, cuts, and tightness ofthe connection at the coolant recovery bottle
and radiator. Inspect the entire system for
leaks. DO NOT REMOVE THE COOLANT
PRESSURE CAP WHEN THE COOLING SYS-
TEM IS HOT.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
