How the System Works
When the vehicle is started, both outside mirror displays will briefly come on to indicate that the system is operating. While driving forward, the left or right side mirror SBZA display will light up if a vehicle is detected in that blind zone. If you activate a turn signal and a vehicle has been detected on the same side, the SBZA display will flash to give you extra warning not to change lanes.
SBZA displays do not come on while the vehicle is approaching or passing other vehicles. At speeds greater than 32 km/h (20 mph), SBZA displays may come on when a vehicle you have passed remains in or drops back into the detection zone.
SBZA can be disabled through vehicle personalization. See Vehicle Personalization for more information. If the SBZA is disabled by the driver, the SBZA mirror displays will not light up during normal driving.
