Buick 2013 Encore Owner's Manual page 223

High-toned beeps from the front
speakers are for objects detected
near the front bumper. Low-toned
beeps from the rear speakers are
for objects detected near the rear
bumper. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds.
Objects Detected by Both the
Front and Rear Sensors
In general, if objects are detected at
the same time near both the front
and rear bumpers while backing up,
the beeps only sound to indicate
that objects are close to the rear
bumper.
However, if an object comes within
0.3 m (1 ft) of the front bumper while
the vehicle is backing up and at the
same time there is another object
further than 0.3 m (1 ft) from the rear
bumper, then the beeps only sound
to indicate the front object.
Turning the System On and Off
The UFRPA system can be turned
on and off by pressing the park
assist button on the center stack.
The indicator on the park assist
button lights up when the system is
on and turns off when it has been
disabled.
When the system is off, PARK
ASSIST OFF briefly displays on the
Driver Information Center (DIC).
UFRPA defaults to the on setting
each time the vehicle is started.
Driving and Operating
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARKING ASSIST: If
this message occurs, take the
vehicle to your dealer to repair the
system.
PARK ASSIST OFF: If the UFRPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
The driver has disabled the
system.
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

The park assist sensors are
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
