9-38 Driving and Operating
WARNING (Continued)
damage, even with URPA, always
check the area around the vehicle
and check all mirrors before
reversing.
How the System Works
URPA comes on automatically when
the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. 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.
To be detected, objects must be at
least 25 cm (10 in) off the ground
and below boot or tailgate level.
Objects must also be within 2.5 m
(8 ft) of the rear bumper. This
distance may be less during warmer
or humid weather.
Turning the System On and Off
The system can be disabled through
the Driver Information Centre (DIC).
See "Parking Assist" under Driver
Information Centre (DIC) on
page 5 28 for more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
PARKING ASSIST OFF: This
message occurs if the driver
disables the system or if vehicle is
driven above 8 km/h (5 mph) in
R (Reverse).
SERVICE PARKING ASSIST: If
this message occurs, take the
vehicle to your dealer to repair the
system.
PARK ASSIST BLOCKED SEE
OWNER'S MANUAL: If the URPA
system does not activate due to a
temporary condition, this message
displays on the DIC. This can occur
under the following conditions:
The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice and slush. For cleaning
instructions, see Exterior Care
on page 10 99.
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
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
A trailer was attached to the
vehicle, or an object was
hanging out of the boot or
tailgate during the last drive
