Mexico-7707484) - 2015 - CRC - 5/8/14

Driving and Operating
RPA operates only at speeds less
than 8 km/h (5 mph).
A detected 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.
Turning the System On and Off
The RPA system can be turned on
and off using the infotainment
system controls. See
for
more information.
The On with Tow Bar Attached
setting allows for the parking assist
to work properly with a small item
attached to the trailer hitch.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
RPA defaults to the on setting each
time the vehicle is started.
Turn RPA off when towing a trailer.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST:
If
this message occurs, check the
following conditions:
.
The sensors are not clean. Keep
the vehicle's rear bumper free of
mud, dirt, snow, ice, and slush.
For cleaning instructions, see
.
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 message may not
clear until the frost or ice has
melted.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
PARK ASSIST OFF:
If the RPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
.
The driver has disabled the
system.
.
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, RPA 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.
