Warning (Continued)
damage, even with URPA, always
check the area around the vehicle
and check all mirrors before
backing.
How the System Works
URPA comes on automatically when
the shift lever is moved into
R (Reverse).
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
40 cm (16 in) the beeping is a
continuous tone for five seconds.
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below liftgate 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.
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 5-28 for
more information.
When the System Does Not
Seem to Work Properly
This light may come on for the
following reasons:
The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10-76.
Driving and Operating
The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The light may not clear
until the frost or ice has melted.
A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
object is removed, URPA will
return to normal operation.
A tow bar is attached to the
vehicle.
The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
