Shifting Out of Park
Automatic Transmission Shift Lock
This vehicle has an electronic shift lock release system.
The shift lock release is designed to:
Prevent ignition key removal unless the shift lever is
in P (Park)
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN and the regular
brake pedal is applied.
The shift lock is always functional except in the case of a
an uncharged or low voltage (less than 9 volt) battery.
If the vehicle has an uncharged battery or a battery with
low voltage, try charging or jump starting the battery.
SeeJump Starting on page 5-46.
Console Shift
If the console shifter cannot be moved out of P (Park)
1. Apply and maintain the regular brakes.
2. Turn the ignition to ON/RUN position. SeeIgnition
Positions on page 2-21for more information.
3. Let up on the shift lever and make sure the shift
lever is pushed all the way into P (Park).
4. Then, move the shift into the desired gear.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Column Shift
If the shifter cannot be moved out of P (Park)
1. Apply and maintain the regular brakes.
2. Turn the ignition key to the ON/RUN position. See
Ignition Positions on page 2-21for more information.
3. Shift out of the P (Park) position to the N (Neutral)
position.
4. Then, move the shift into the desired gear.
If you still cannot move the shift lever from P (Park),
consult your dealer/retailer or a professional towing
service.
Parking Over Things That Burn
{CAUTION:

Running the Vehicle While Parked
It is better not to park with the engine running. But if you
ever have to, here are some things to know.
{CAUTION:
Idling a vehicle in an enclosed area with poor
ventilation is dangerous. Engine exhaust may
enter the vehicle. Engine exhaust contains Carbon
Monoxide (CO) which cannot be seen or smelled.
It can cause unconsciousness and even death.
Never run the engine in an enclosed area that
has no fresh air ventilation. For more information,
seeEngine Exhaust on page 2-32.
{CAUTION:
It can be dangerous to get out of the vehicle if the
automatic transmission shift lever is not fully in
P (Park) with the parking brake rmly set. The
vehicle can roll. Do not leave the vehicle when the
engine is running unless you have to. If you have
left the engine running, the vehicle can move
suddenly. You or others could be injured. To be
sure the vehicle will not move, even when you are
on fairly level ground, always set the parking
brake and move the shift lever to P (Park).
Follow the proper steps to be sure the vehicle will not
move. SeeShifting Into Park on page 2-28.
If parking on a hill and pulling a trailer, seeTowing a
Trailer on page 4-25.

When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK ASSIST OFF will be
displayed on the DIC and a red light will be shown on
the rear URPA display when the shift lever is moved into
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow, ice and
slush. For cleaning instructions, seeWashing Your
Vehicle on page 5-96.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the last
drive cycle, the red light may illuminate in the rear
display. Once the attached object is removed, URPA
will return to normal operation.
A tow bar is attached to the vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled after driving forward at least
15 mph (25 km/h), take the vehicle to your dealer/retailer.

This light comes on briey
when the ignition key is
turned to START, but the
engine is not running, as a
check to show it is working.
If it does not, have the vehicle serviced by your
dealer/retailer.
The light should go out once the engine starts. If it stays
on, or comes on while driving, there could be a problem
with the charging system. A charging system message
in the Driver Information Center (DIC) can also appear.
SeeDIC Warnings and Messages on page 3-56for
more information. This light could indicate that there are
problems with a generator drive belt, or that there is an
electrical problem. Have it checked right away. If the
vehicle must be driven a short distance with the light
on, turn off accessories, such as the radio and air
conditioner.
Brake System Warning Light
The vehicle’s hydraulic brake system is divided into
two parts. If one part is not working, the other part can
still work and stop the vehicle. For good braking both
parts need to be working.
If the warning light comes on, there is a brake problem.
Have the brake system inspected right away.
This light should come on briey when the engine is
started. If it does not come on then, have it xed so it
will be ready to warn if there is a problem.

When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The light
will stay on if the parking brake does not fully release.
If it stays on after the parking brake is fully released,
it means there is a brake problem.
{CAUTION:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the light comes on while driving, pull off the road and
stop carefully. The pedal can be harder to push, or the
pedal could go closer to the oor. It could take longer to
stop. Try turning off and restarting the vehicle one or two
times, if the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 4-23.
Antilock Brake System (ABS)
Warning Light
For vehicles with
the Antilock Brake
System (ABS), this light
comes on briey when
the engine is started.

the indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the
light comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on, or
comes on again while driving, the vehicle needs service.
If the regular brake system warning light is not on, the
vehicle still has brakes, but not antilock brakes. If the
regular brake system warning light is also on, the vehicle
does not have antilock brakes and there is a problem with
the regular brakes. SeeBrake System Warning Light on
page 3-38.
