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 trunk or liftgate level.
Objects must also be within 2.5m (8 ft) of the rear bumper.
This distance may be less during warmer or humid weather.
