232 Driving and Operating
system is turned off, a system off message
is shown on the display. This message
disappears after a short period of time.
If the vehicle has a trailer hitch attached,
select ON - ATTACHED using the
infotainment system menus to allow Park
Assist to function properly. Park Assist is
able to compensate for a trailer hitch up to
0.3 m (1 ft) in length and width. Park Assist
may not function properly with larger trailer
hitches and provide inaccurate information
of objects in the rear.
Turn off Park Assist when towing a trailer to
prevent unwanted beeps and when a bike
rack is attached to ensure proper operation.
The Park Assist System can also be turned
on or off using the infotainment system.
SeeVehicle Personalization 0110.
When the System Does Not Seem to Work
Properly
If a service message displays, check the
following conditions:
.The sensors may not be clean. Keep the
vehicle's front and rear bumpers free of
mud, dirt, snow, ice, and slush. For
cleaning instructions, see Exterior Care
0 311.
.The Park Assist sensors may be 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 a service message displays and the above
conditions do not exist, take the vehicle to
your dealer for repairs.
If the Park Assist System does not activate
due to a temporary condition, a system off
message is shown on the display. This can
occur under the following conditions:
.The driver has disabled the system.
.An object is currently blocking the rear
sensors (for example, bike rack, tailgate,
trailer hitch, etc.). Once the object is
removed, Park Assist will return to normal
operation.
.The bumper is damaged. Take the vehicle
to your dealer for repairs.
.Other conditions, such as vibrations from
a jackhammer or the compression of air
brakes on a very large truck, are affecting
system performance.
Automatic Parking Assist (APA)
Enhanced Automatic Parking Assist (APA)
If equipped, under certain conditions
Enhanced Automatic Parking Assist (APA) can
use sensors based on sonar technology
along the vehicle’s front, rear and sides to
detect a parking spot and automatically park
the vehicle. The vehicle will automatically
maneuver into a detected spot moving at or
near idle speed. It does this by
automatically steering, braking, accelerating,
and gear shifting. The driver must always be
prepared to apply braking if necessary. A
display and beeps help to guide the parking
maneuvers.
{Warning
APA may not always detect objects in the
parking space, objects that are not rigid
(e.g. shrubs and chain-link fences), objects
below the bumper, objects high off the
ground (e.g. flatbed trucks), hanging
objects, objects below ground level such
(e.g. large potholes), or moving objects
(e.g. pedestrians, cyclists, vehicles).
Always verify that the parking space is
appropriate for parking a vehicle. APA (Continued)
