Park Assist
The vehicle may be equipped
with the Rear Park Assist
(RPA) or Front and Rear Park
Assist (FRPA). The Park Assist
system may provide
assistance to driver when
backing up and parking. Park
Assist uses ultrasonic sensors
in the bumpers to measure the
distance between the vehicle
and objects. The system
calculates the distance
between vehicle and object via
measuring the time it takes for
the ultrasonic waves to
bounce back from the object. Park Assist works only at
speeds up to about 11 Km/h
(7 mph). An illuminated LED in
the parking assist button
indicates that the system is
ready to operate. The sensors
on the bumpers may detect
objects up to 1.8m (6 ft) behind
and 1.25m (4 ft) in front of the
vehicle within a zone 25 cm
(10 in) high off the ground and
below bumper level. These
detection distances may be
shorter during warmer or
humid weather. Blocked
sensors will not detect objects
and can also cause false
detections. Keep the sensors
clean of mud, dirt, snow, ice,
and slush; and clean sensors
after a car wash in freezing
temperatures.
{Warning
The Park Assist System is
no substitute for careful and
attentive driving. The Park
Assist system does not
(Continued)
Warning (Continued)
detect children, pedestrians,
bicyclists, animals, or objects
located below the bumper or
that are too close or too far
from the vehicle. It is not
available at speeds greater
than 11 km/h (7 mph). To
prevent injury, death,
or vehicle damage, even with
Park Assist, always check
the area around the vehicle
and check all 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.
Beeps sound to warn the
driver of certain objects that
are detected around the
vehicle. The frequency of
beeps increases as the vehicle
gets closer to the object.
When the object is very close
to the vehicle, the beeps are
continuous. Beeps for the
front are higher pitched than
beeps for the rear. If equipped
with Safety Alert seat, both
sides of the seat will pulse
alongside the beeps. 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 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
