Buick 2010 Lucerne Automobile User Manual


 
How the System Works
URPA comes on automatically when the shift lever
is moved into R (Reverse). The rear display briefly
illuminates to indicate the system is working.
URPA operates only at speeds less than 8 km/h
(5 mph). If the vehicle is above this speed, the red
light on the rear display will flash.
To be detected, objects must be at least 25 cm (10 in)
off the ground and below trunk level. Objects must
also be within 2.5 m (8 ft) from the rear bumper. This
distance may be less during warmer or humid weather.
A single beep will sound the first time an object is
detected between 1 m (40 in) and 2.5 m (8 ft) away.
Beeping will occur continuously when the vehicle is
at 0.6 m (23 in) or closer to an object.
The following describes what will occur with the URPA
display as the vehicle gets closer to a detected object:

The system can be disabled through the Driver
Information Center (DIC). See “Park Assist” under
DIC Operation and Displays on page 4-47 for more
