Driving Your Mazda Starting and Driving Blind Spot Monitoring (BSM) System í The Blind Spot Monitoring (BSM) system is designed to assist the driver by monitoring blind spots on both sides of the vehicle to the rear in certain situations such as when changing lanes on roads and freeways. The BSM system monitors the detection areas on both sides of the vehicle to the rear when the vehicle speed is about 32 km/h (20 mph) or more, and notifies the driver of vehicles in the detection area by illuminating the BSM warning light. If the turn signal lever is operated in the direction the BSM warning light is illuminated, the system warns the driver of the vehicle in the detection area with a beep sound. Detection areas WARNING Do not rely completely on the BSM system and be sure to look over your shoulder before changing lanes: The BSM system can assist the driver in confirming the safety of the surroundings but is not a complete substitute. The driver is responsible for assuring lane changes and other maneuvers. Always pay attention to the direction in which the vehicle is traveling and the vehicle's surroundings. NOTE l l l l The BSM system does not operate when the vehicle speed is lower than about 32 km/h (20 mph). The radar sensors are equipped inside the rear bumper. (page 5-36) The system may not operate normally when towing a trailer. Turn off the system by operating the BSM OFF switch when towing a trailer. The radar sensors do not detect human, animal, or static objects such as fences. In addition, the system pauses when the selector lever is shifted to the R position. (The system resumes automatically when the selector lever is shifted from the R position.) í Some models. 5-33
