mirrors before moving forward or
backing.
How the System Works
The instrument cluster may have a
Park Assist display with bars that
show distance to object, driving
direction, and object location
information for the Park Assist
system. As the object gets closer, more
bars light up and the bars change
color from yellow to amber to red.
When an object is very close to the
vehicle rear (<0.6m (2 ft)), five beeps
will sound from the rear followed by a
continuous beep from the rear,
or both sides of the Safety Alert Seat
will pulse five times. When an object
is very close to the vehicle front
(<0.3m (1 ft)), a continuous beep will
sound from the front, or both sides of
the Safety Alert Seat will pulse five
times. Beeps for FPA are higher
pitched than for RPA.
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 Exterior
Care 0 348.
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.
DRIVING AND OPERATING
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system.
PARK ASSIST OFF : If the PA system
does not activate due to a temporary
condition, the appropriate message
displays on the DIC. PA OFF message
is displayed when disabled by the
driver. Front/Rear PA OFF message is
displayed when an attached object is
detected in the front or rear
respectively. PA Temporarily
Unavailable message is displayed for
system failures. This can occur under
the following conditions:
The driver has disabled the system.
An object was hanging out of the
trunk 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.
