308 DRIVING AND OPERATING
When the System Does Not Seem to
Work Properly
The following messages may be shown
on the display:
SERVICE PARK ASSIST
If this 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 Care0432.
.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 this message displays and the above
conditions do not exist, take the
vehicle to your dealer for repair. PARK ASSIST OFF
If the Park Assist System does not
activate due to a temporary condition,
this 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.
Backing Warning and Reverse
Automatic Braking (RAB)
Vehicles with Adaptive Cruise Control
(ACC) have the Backing Warning
System and Reverse Automatic
Braking (RAB) system. When in
R (Reverse), Backing Warning alerts of
rear objects at vehicle speeds greaterthan 8 km/h (5 mph), and RAB may
automatically brake hard at speeds
between 1–32 km/h (0.5–20 mph).
RAB may activate unintendedly if
there is an object attached to vehicle.
To disable RAB, press the
Xbutton.
The Backing Warning System will
beep once from the rear when an
object is first detected, or pulse twice
on both sides of the Safety Alert Seat.
When the system detects a potential
crash, beeps will be heard from the
rear, or five pulses will be felt on both
sides of the Safety Alert Seat. There
may also be a brief, sharp application
of the brakes.
