DRIVING AND OPERATING
245
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.
Turning the System On and Off
The Park Assist System can be turned
on or off using the infotainment
system. See
.
The
X
button is used to turn on or
off the Park Assist, which also turns
the Reversing Warning and Reverse
Automatic Braking (RAB) on or off at
the same time. When the system is
turned off, a system off message is
shown on the display. This message
disappears after a short period
of time.
Turn off Park Assist when towing a
trailer and when a bike rack is
attached to prevent unwanted beeps
and to ensure proper operation.
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
.
.
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.
