Circuit/System Description

When the system detects a vehicle in the side blind zone while driving the Left or Right Side Object Sensor will send a signal via serial data to the appropriate Door Lock/Window Switch. The Door Lock/Window switch supplies power and ground to the outside rearview mirror. When commanded via serial data, the Door Lock/window switch will provide power to the outside rear view mirror. The amber warning symbol will light up in the appropriate outside mirror. This indicates that it may be unsafe to change lanes. If the driver then activates the turn signal, the amber warning symbol starts flashing as an extra warning not to change lanes. An audible alert will also sound.

Side blind zone alert is active when the vehicle is out of park or the parking brake is off on manual transmission vehicles and from speeds of 10 km/h (6.2 MPH) up to 140 km/h (87 MPH). Driving faster deactivates the system, indicated by dimly lighting the warning symbols in the mirrors. Driving under this speed again will turn off the warning symbols. If then a vehicle is detected in the blind zone, the warning symbols will turn on normally on the appropriate side. When the vehicle is started, both outside mirror displays will briefly come on to indicate that the system is operating.
