How the System Works
RPA comes on automatically when
the shift lever is moved into
R (Reverse).
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.
Turning the System On and Off
The RPA system can be turned on
and off using the infotainment
system controls. See Vehicle
Personalization 0 114.
When the System Does Not
Seem to Work Properly
This light may come on for the
following reasons:
The sensors are not clean. Keep
the vehicle's rear bumper free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
Exterior Care 0 298.
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.
An object was hanging out of the
liftgate during the last drive
cycle. Once the object is
removed, RPA will return to
normal operation.
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.
Driving and Operating
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
