i
s
very close to the vehicle, the beeps are
continuous. The beeps may be muted by
pressing the on screen mute button.
Turning the System On and Off
To view available settings for this feature,
touch the Settings icon on the infotainment
home page. Select “Vehicle” to display the
list of available options and select “Collision/
Detection Systems”.
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, as it can cause the system
to 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.
When the System Does Not Seem to
Work Properly
If aservice message displays, check the
following conditions:
•
Th
e sensors may not be clean. Keep
the vehicle's rear bumpers free of mud,
dirt, snow, ice, and slush. For cleaning
instructions, see Exterior Care 3278.
•
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.
•
Ot
her conditions, such as vibrations from
ajackhammer or the compression of air
brakes on avery large truck, are affecting
system performance.
