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 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.

Driving and Operating
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 Exterior Care 0 353.
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.
