Cadillac CTS/CTS-V Owner Manual - 2011
9-44 Driving and Operating
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.
Objects must be at least 25.4 cm
(10 in) off the ground and below
trunk level, and within 2.4 m (8 ft)
from the rear bumper to be
detected. The distance may be
less during warmer or humid
weather.
A single beep sounds the
first time an object is detected
between 1.0 m (40 in) and 2.4 m
(8 ft) away. Beeping occurs
continuously when the vehicle is
0.3 m (12 in) or closer to an object.
The system can be disabled through
the Driver Information Center (DIC).
See “Parking Assist” under Driver
Information Center (DIC) on
page 5‑27 for more information.
When the System Does Not
Seem to Work Properly
If the URPA system will not activate
due to a temporary condition, the
message PARK ASSIST OFF will be
displayed on the DIC when the shift
lever is moved into R (Reverse).
This occurs under the following
conditions:
.
The driver disables the system.
.
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 10‑113.
.
A trailer was attached to the
vehicle, or a bicycle or an object
was hanging out of the trunk
during the last drive cycle. Once
the attached object is removed,
URPA will return to normal
operation.
.
A tow bar is attached to the
vehicle.
.
The vehicle's bumper is
damaged. Take the vehicle to
your dealer 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.
Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera system. Read this entire
section before using it.
The rear vision camera system is
designed to help the driver when
backing up by displaying a view of
the area behind the vehicle.
