The system can be disabled through
the Driver Information Center (DIC).
See “Park Assist” under DIC
Operation and Displays on
page 3-41 for more information.
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 may
occur under the following
conditions:
The driver disables the system.
The parking brake pedal is
depressed.
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 5-86 .
A trailer was attached to the
vehicle, or a bicycle or an
object was hanging out of the
liftgate 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.
