9-46 Driving and Operating
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in), the beeping is
continuous for five seconds.
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below trunk level. Objects must also
be within 2.5 m (8 ft) from the rear
bumper. The distance objects can
be detected may be less during
warmer or humid weather.
PARK ASSIST OFF displays on
the Driver Information Center (DIC)
to indicate that URPA is off.
The message disappears after
a short period of time.
See Object Detection System
Messages on page 5 39 for URPA
messages.
Turning the System On and Off
The URPA system can be turned
on and off using the infotainment
system controls. See Vehicle
Personalization on page 5 43
for more information.
URPA defaults to the on setting
each time the vehicle is started.

When the System Does Not
Seem to Work Properly
If the URPA system does not

This can occur under the following
conditions:
The driver has disabled the
system.
The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning

The park assist sensors are
covered by frost or ice, which
can occur after washing the
vehicle in cold weather. Keep
