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 REVERSE (R). This occurs
under the following conditions:

The driver disables the system. See

DIC

Controls and Displays on page 212

.

The parking brake pedal is pressed.

A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.

The ultrasonic sensors are not kept clean. So,
be sure to keep your vehicle’s rear bumper free
of mud, dirt, snow, ice, and slush. For cleaning
instructions, see

Washing Your Vehicle on

page 422

. If the DIC still displays the PARK

ASSIST OFF message after cleaning the
bumper and driving forward at a speed of at
least 15 mph (25 km/h), see your dealer.

Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.

When URPA is disabled without driver action
and the driver attempts to turn URPA back on
using the Driver Information Center (DIC), the
PARK ASSIST ON option will not be selectable
if the necessary conditions stated above for
normal system operation are not met.

As always, drivers should use care when backing
up a vehicle. Always look behind you, being sure to
check for other vehicles, obstructions and blind
spots.
