Buick Regal: Ultrasonic Parking Assist
For vehicles with the Ultrasonic Rear Parking Assist (URPA) system, it assists the driver with parking and avoiding objects while in R (Reverse). URPA operates at speeds less than 8 km/h (5 mph), and the sensors on the rear bumper detect objects up to 1.5 m (5 ft) behind the vehicle, and at least 25 cm (10 in) off the ground.
The Ultrasonic Rear Parking Assist (URPA) system does not replace driver vision. It cannot detect:
If you do not use proper care before and while backing up, vehicle damage, injury, or death could occur. Even with URPA, always check behind the vehicle before backing up. While backing up, be sure to look for objects and check the vehicle's mirrors.
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 beeps are continuous.
To be detected, objects must be at least 25 cm (10 in) off the ground and below trunk level. Objects must also be within 1.5 m (5 ft) from the rear bumper. The distance at which objects can be detected may be less during warmer or humid weather.
PARK ASSIST OFF displays on the Driver Information Center (DIC) to indicate that URPA is off. The message disappears after a short period of time.
Turning the System On and Off
The URPA system can be turned on and off using the park assist button located next to the radio.
The park assist button lights up when the system is on or in standby and turns off when it has been disabled.
URPA defaults to the on setting each time the vehicle is started.
When the System Does Not Seem to Work Properly
SERVICE PARK ASSIST: If this message occurs, take the vehicle to your dealer to repair the system.
PARK ASSIST OFF: If the URPA system does not activate due to a temporary condition, the message displays on the DIC. See Driver Information Center (DIC) for more information.
This can occur under the following conditions:► The driver has disabled 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 . ► An object was hanging out of the trunk during the last drive cycle.
Once the object is removed and URPA detects no objects of interest, the URPA will return to normal operation.► The vehicle's bumper is damaged. Take the vehicle to your dealer to repair the system. ► Other conditions, such as vibrations from a jackhammer or the compression of air brakes on a very large truck, are affecting system performance.
If the system is still disabled after checking all conditions listed above and driving forward at least 40 km/h (25 mph), take the vehicle to your dealer.
