Buick LaCrosse: 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 20 cm (8 in) off the ground and below trunk level. Objects must also be within 2.5 m (8 ft) from the rear bumper. The distance at which objects can be detected may be less during warmer or humid weather.

Parking Assist (URPA) system

avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph).
