Missed alerts can occur under normal circumstances and will increase in wet conditions. The system does not need to be serviced. SBZA is designed to ignore stationary objects; however, the system may occasionally light up due to guard rails, signs, trees, shrubs, and other stationary objects. This is normal system operation, the vehicle does not need service.

If the SBZA displays do not light up when the system is on and vehicles are in the blind zone, the system may need service. Take the vehicle to your dealer.

SBZA does not operate when the SBZA sensors in the left or right corners of the rear bumper are covered with mud, dirt, snow, ice, slush, or in heavy rainstorms. For cleaning instructions, see “Washing the Vehicle” under Exterior Care  . If the DIC still displays the SIDE BLIND ZONE SYSTEM UNAVAILABLE message after cleaning the bumper, see your dealer.

The SBZA displays may remain on if a trailer is attached to the vehicle, or a bicycle or object is extending out to either side of the vehicle.

When SBZA is disabled for any reason other than the driver turning it off, it cannot be turned back on. The SIDE BLIND ZONE ALERT ON option will not be selectable if the conditions for normal system operation are not met.
