Leaving the Vehicle With the Engine
Running (Automatic Transmission)
{CAUTION:
It can be dangerous to leave the vehicle with the
engine running. The vehicle could move suddenly if
the shift lever is not fully in P (Park) with the parking
brake rmly set. And, if you leave the vehicle with
the engine running, it could overheat and even
catch re. You or others could be injured. Do not
leave the vehicle with the engine running.
If you have to leave the vehicle with the engine running,
the vehicle must be in P (Park) and the parking brake
set. After shifting into P (Park), try to move the shift lever
out without rst pushing the button on the shift lever.
If you can, the shift lever was not fully locked into
P (Park).
Torque Lock (Automatic Transmission)
Torque lock is when the weight of the vehicle puts too
much force on the parking pawl in the transmission.
This happens when parking on a hill and shifting the
transmission into P (Park) is not done properly and then it
is difficult to shift out of P (Park). To prevent torque lock,
set the parking brake and then shift into P (Park). To nd
out how, see″Shifting Into P (Park)″listed previously.
If torque lock does occur, your vehicle may need to be
pushed uphill by another vehicle to relieve the parking
pawl pressure, so you can shift out of P (Park).
Shifting Out of Park
This vehicle is equipped with 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) with the shift lever button fully
released, for vehicles with key access.
Prevent movement of the shift lever out of P (Park),
unless the ignition is in ON/RUN or
ACC/ACCESSORY and the brake pedal is applied.
The shift lock release is always functional except in the
case of 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.

{CAUTION:
Engine exhaust contains Carbon Monoxide (CO)
which cannot be seen or smelled. Exposure to
CO can cause unconsciousness and even death.

or damage.
The vehicle’s exhaust system has been
modi ed, damaged or improperly repaired.
There are holes or openings in the vehicle
body from damage or after-market

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, see
Washing Your Vehicle on page 5-110.
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.
