Side Blind Zone; Alert (Sbza) - GMC Acadia Owner's Manual

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
continuous for five seconds.

The system can be disabled through
the Driver Information Center (DIC).

following conditions:
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

the last drive cycle. Once the
object is removed, URPA will
return to normal operation.
