8-40 Driving and Operating
Turning the System On and Off
The UFRPA system can be turned
on and off by pressing the park
assist button located next to the
shift lever.
The park assist button lights up
when the system is on and turns off
when it has been disabled.
When the System Does Not
Seem to Work Properly
If UFRPA does not turn on due to a
temporary condition, the message
PARK ASSIST OFF displays on the
DIC, and the light on the park assist
button turns off. This can occur
under the following conditions:
.
The ultrasonic sensors are not
clean. Keep the vehicle's
bumpers free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 9‑109
.
.
A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
attached object is removed,
UFRPA will return to normal
operation.
.
If an object is attached to the
front of the vehicle.
.
A tow bar is attached to the
vehicle.
.
The vehicle's bumper is
damaged. Take the vehicle to
your dealer/retailer to repair the
system.
.
Other conditions may affect
system performance, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck.
If the system is still disabled, after
driving forward at least 25 km/h
(15 mph), take the vehicle to your
dealer/retailer.
