Buick LaCrosse: SBZA Error Messages
The following messages may appear on the infotainment display:
SIDE BLIND ZONE ALERT SYSTEM OFF: This message indicates that the driver has turned the system off.
SIDE BLIND ZONE SYS.
UNAVAILABLE: This message indicates that the SBZA system is disabled because the sensor is blocked and cannot detect vehicles in the blind zone. The sensor may be blocked by mud, dirt, snow, ice, or slush. This message may also activate during heavy rain or due to road spray. The vehicle does not need service. For cleaning, see Exterior Care.
SERVICE BLIND ZONE ALERT SYSTEM: If this message appears, both SBZA displays will remain on indicating there is a problem with the SBZA system. If these displays remain on after continued driving, the system needs service. Take the vehicle to your dealer.
