CAUTION!(Continued)
the vehicle’s battery will discharge sufficiently to
degrade battery life and/or prevent the engine from
starting.
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 shift
lever. 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 push 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 theESC Offswitch (if necessary), to place
the Electronic Stability Control (ESC) system inPartial
Offmode, before rocking the vehicle. Refer to “Elec-
tronic Brake Control” in “Starting And Operating” for
further information. Once the vehicle has been freed,
push theESC Offswitch again to restoreESC On
mode.
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

CAUTION!(Continued)
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.
WARNING!
Fast spinning tires can be dangerous. Forces gener-
ated 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 vehi-
cle’s wheels faster than 30 mph (48 km/h) or for
longer than 30 seconds continuously without stop-
ping 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 be-
tween 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 trans-
mission shifting occurring).
MANUAL PARK RELEASE
WARNING!
Always secure your vehicle by fully applying the
parking brake, before activating the Manual Park

WARNING!(Continued)
Release. Activating the Manual Park Release will
allow 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. Open the center console and locate the Manual Park
Release cover, remove it by snapping the cover away
from the console hinges.3. Using a screwdriver or similar tool, push the metal
latch in towards the tether strap.

4. While the metal latch is in the open position, simulta-
neously pull upwards on the tether strap until the
lever clicks and latches in the released position. The
transmission is now out of PARK and the vehicle can
be moved.CAUTION!
Closing the armrest while the Manual Park Release is
activated may damage the Manual Park Release
mechanism, the transmission, and/or the armrest.

NOTE:To prevent the vehicle from rolling unintention-
ally, firmly apply the parking brake.
To Disengage the Manual Park Release Lever:
1. To disengage the Manual Park Release apply tension
upward while pushing the release latch towards the
tether to unlock the lever.
2. Once the tension has been released and the lever has
been unlocked be sure it is stowed properly and locks
into position.

TOWING A DISABLED VEHICLE
The manufacturer requires towing your vehicle with all
four wheels OFF the 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 un-
der the New Vehicle Limited Warranty.

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors
the performance of the emissions, engine, and automatic
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II system
will turn on the “Malfunction Indicator Light (MIL).” It
will also store diagnostic codes and other information to
assist your service technician in making repairs. Al-
though your vehicle will usually be drivable and not
need towing, see your authorized dealer for service as
soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emissions
tests can be performed.
•If the MIL is flashing, while the engine is running,
severe catalytic converter damage and power loss
will soon occur. Immediate service is required.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control system.
Failure to pass could prevent vehicle registration.
For states that require an Inspection and Mainte-
nance (I/M), this check verifies the “Malfunction
