while gently pressing the accelerator. Use the least amount
of accelerator pedal pressure that will maintain the rocking
motion, without spinning the wheels or racing the engine.
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.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine 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 prolonged efforts to
free a stuck vehicle.
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
“Starting And Operating” for further information. Once
the vehicle has been freed, push the ESC Offswitch again
to restore ESC Onmode.
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!
•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).

MANUAL PARK RELEASE — 8 SPEED
TRANSMISSION
WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park
Release. Activating the Manual Park Release will al-
low your vehicle to roll away if it is not secured by the
parking brake or by proper connection 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 order to move the vehicle in cases where the transmis-
sion will not shift out of PARK (such as a dead battery), a
Manual Park Release is available.
Follow these steps to use the Manual Park Release:
1. Firmly apply the parking brake.
2. Remove the console storage bin. 3. Remove the plastic cover under the bin by using the slot
provided to access the Manual Park Release lever.
4. Using a small screwdriver or similar tool, fish the tether strap up through the opening in the console base.
5. Insert the screwdriver into the slot in the center of the lever, and disengage the lever locking tab by pushing it
to the right.

6. While holding the locking tab in the disengaged posi-tion, pull the tether strap to rotate the lever up and
rearward, until it locks in place in the vertical position.
The vehicle is now out of PARK and can be moved.
Release the parking brake only when the vehicle is
securely connected to a tow vehicle. To Reset The Manual Park Release:
1. Push the latch (at the base of the lever, on the rear side)
rearward (away from the lever) to unlatch the lever.
2. Rotate the Manual Park Release lever forward and down, to its original position, until the locking tab snaps
into place to secure the lever.
3. Pull up gently on the tether strap to confirm that the lever is locked in its stowed position.

Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks. •
Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Schedule” for the proper maintenance
intervals.
