Side Blind Zone Alert (Sbza) - Buick 2009 Lucerne Owner's Manual

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 and a red light will be shown on
the rear URPA display 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
Washing Your Vehicle on page 5-92.
•
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the trunk during the
last drive cycle, the red light may illuminate in
the rear display. Once the attached object is
removed, URPA will return to normal operation.
•
A tow bar is attached to the vehicle.
2-40
•
The vehicle's bumper is damaged. Take the vehicle
to your dealer/retailer 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.
If the system is still disabled after driving forward at least
15 mph (25 km/h), take the vehicle to your dealer/retailer.
