Side Blind Zone Alert (SBZA)

For vehicles with this feature, it may alert you to vehicles located in your side blind zone. When the system detects a vehicle in the side blind zone, an SBZA display will light up in the corresponding outside side mirror indicating that it may not be safe to change lanes.

The system is enabled at every vehicle startup. It can be disabled through the Driver Information Center (DIC).

If the message SIDE BLIND ZONE SYS. UNAVAILABLE appears on the DIC, the system has been disabled because the sensor is blocked and cannot detect vehicles in the blind zone. The sensors, located behind the rear quarter panels, may be blocked by mud, dirt, snow, ice, slush, or even heavy rainstorms. The vehicle does not need service.

See Side Blind Zone Alert (SBZA) for more information.
