SBZA Detection Zones
The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, 3.5 m (11 ft).
This zone starts at each side mirror and goes back approximately 5 m (16 ft). The height of the zone is approximately between 0.5 m (1.5 ft) and 2.0 m (6 ft) off the ground.
The SBZA detection zones do not change if the vehicle is towing a trailer. So be extra careful when changing lanes while towing a trailer.
