Ultrasonic Rear Parking Assist (URPA) comes on
automatically when the shift lever is moved into
R (Reverse). The rear display will then briefly illuminate
to let you know the system is working.
The following describes what will occur with the rear
display as you get closer to an object detected in the
rear of your vehicle:
Description Metric English
amber light 2.5 m 8 ft.
amber/amber lights 1.0 m 40 in.
amber/amber/red lights and
continuous beeping for
five seconds
0.6 m 23 in.
amber/amber/red lights
flashing and continuous
beeping for five seconds
0.3 m 1 ft.
The system can be disabled through the Driver
Information Center (DIC). See “Parking Assist” under
DIC Operation and Displays
on page 4‑60
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 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 6‑98.
.
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 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 25 km/h (15 mph), take the vehicle to your dealer.
