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 and REVERSE
while gently pressing the accelerator.
NOTE:Shifts between DRIVE and REVERSE can only be
achieved at wheel speeds of 5 mph (8 km/h) or less.
Whenever the transmission remains in NEUTRAL for more
than two seconds, you must press the brake pedal to
engage DRIVE or REVERSE.
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 switch, to place the Electronic
Stability Control (ESC) system in Partial Offmode, before
rocking the vehicle. Refer to “Electronic Brake Control” in
“Safety” for further information. Once the vehicle has been
freed, push the ESC Offswitch 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 transmission failure during pro-
longed 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.

IN CASE OF EMERGENCY 387
CAUTION!(Continued)
•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).
TOWING A DISABLED VEHICLE
The manufacturer requires towing your vehicle with all
four wheels OFFthe ground using a flatbed.
If the key fob is unavailable, or the vehicle’s battery is
discharged, refer to “Manual Park Release” in this section
for instructions on shifting the transmission out of PARK
for loading onto a flatbed truck.
CAUTION!
• Towing this vehicle using any other method can
cause severe transmission and/or transfer case dam-
age.
• Damage from improper towing is not covered under
the New Vehicle Limited Warranty.
ENHANCED ACCIDENT RESPONSE SYSTEM
(EARS)
This vehicle is equipped with an Enhanced Accident
Response System.
Please refer to “Occupant Restraint Systems” in “Safety”
for further information on the Enhanced Accident Re-
sponse System (EARS) function.
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 per-
formed under certain crash or near crash-like situations,
such as an air bag deployment or hitting a road obstacle.
Please refer to “Occupant Restraint Systems” in “Safety”
for further information on the Event Data Recorder (EDR).

In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
•Do not interrupt the ignition when the transmission is in
gear and the vehicle is in motion.
• Do not try to start the vehicle by pushing or towing the
vehicle.
• Do not idle the engine with any ignition components
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
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,
(Continued)
WARNING! (Continued)
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 automatically and may start at any time,
whether the engine is running or not.
• When working near the radiator cooling fan, discon-
nect the fan motor lead or 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.
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, 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 for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
412 SERVICING AND MAINTENANCE
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer’s specified transmission fluid. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.
NOTE:No chemical flushes should be used in any trans-
mission; only the approved lubricant should be used.
CAUTION!
Using a transmission fluid other than the manufactur-
er ’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.
Special Additives
The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmission
Fluid (ATF) is an engineered product and its performance may
be impaired by supplemental additives. Therefore, do not add
any fluid additives to the transmission. Avoid using transmis-
sion sealers as they may adversely affect seals.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine fluid
level checks are not required; therefore the transmission has
no dipstick. An authorized dealer can check your transmission
fluid level using special service tools. If you notice fluid
leakage or transmission malfunction, visit an authorized
dealer immediately to have the transmission fluid level
checked. Operating the vehicle with an improper fluid level
can cause severe transmission damage.
418 SERVICING AND MAINTENANCE
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to
adjust the fluid level accurately.
Fluid And Filter Changes
Under normal operating conditions, the fluid installed at
the factory will provide satisfactory lubrication for the life
of the vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contami-
nated (with water, etc.), or if the transmission is disas-
sembled for any reason.
Front/Rear Axle Fluid
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected.
If gear oil leakage is suspected inspect the fluid level. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for further information.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than 1/8 inch
(3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be tightened to 22
to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than 1/8 inch
(3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be tightened to 22
to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
