SBZA Detection Zones
The SBZA sensor covers a zone of approximately one lane over from both sides of the vehicle, or 3.5m(11 ft). This zone starts at each side mirror and goes back approximately 5.0 m(16 ft). The height of the zone is approximately between 0.5 m(1.5 ft) and 2.0m(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.
