9-64 Driving and Operating SIDE BLIND ZONE SYS. UNAVAILABLE: This message indicates that the SBZA system is disabled either because the sensor is blocked and cannot detect vehicles in your blind zone, or the vehicle is passing through an open field of view area, such as the desert, where there is insufficient data for operation. The sensor may be blocked by mud, dirt, snow, ice, slush, or even heavy rainstorms. This message may also activate during heavy rain or due to road spray. The vehicle does not need service. For cleaning, see "Washing the Vehicle" under Exterior Care on page 10‑98. SERVICE SIDE 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. 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, the driver will not be able to turn SBZA back on using the DIC. The SIDE BLIND ZONE ALERT ON option will not be selectable if the conditions for normal system operation are not met. Until normal operating conditions for SBZA are met, you should not rely upon SBZA while driving.
