Driving Your Mazda Starting and Driving l l l l l l l l l The detectability of the radar sensors has its limitations. The BSM system may not operate properly under the following conditions: Ice, snow, or soil adheres to the rear bumper surface around the radar sensors. During adverse weather conditions such as rain or snow, or under conditions where water is sprayed. The rear bumper area around the radar sensors is blocked by foreign material (such as stickers or a bicycle carrier). The radar sensors may not detect all types of vehicles around your vehicle, especially the following types of vehicles: Motorcycles Vehicles with body shapes that radar may not reflect such as a flatbed trailer with no cargo. Vehicles with lower body height such as sports cars. Have the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied to the rear bumper, even in a minor accident. If the vehicle is driven with a damaged radar sensor, the system may not operate properly resulting in an accident. For repairs or paintwork around the radar sensors, or replacement of the bumper, consult an Authorized Mazda Dealer. The radar sensors of the BSM system may be regulated under the radio wave related laws of the country where the vehicle is driven. The sensors in this system are approved for use in the U.S.A. (including territories), Canada, and Mexico. If a vehicle with a BSM system is driven in a country other than the U.S.A., Canada, or Mexico, the system has to be turned off using the BSM OFF switch. The detection area of the system has been determined based on the lane width of general freeways. Therefore on a road with a narrower lane width, the system may detect vehicles on a lane next to the adjacent lane and operate the warning light/beep. On a road with wider lane width, the system may not detect vehicles on the adjacent lane and may not operate the warning light/beep. Operation of the warning light/beep may be delayed or the system may not operate the warning light/beep under the following conditions: The vehicle accelerates from a standing-start with a vehicle alongside. A vehicle moves from a lane two lanes over to the adjacent lane. The difference in vehicle speed between your vehicle and another vehicle is larger when passing or being passed, and the vehicle passes the detection area within a short period of time. On a steep incline, or when there is a difference in height between lanes. Immediately after the system has been activated by pressing the BSM OFF switch again after it has been turned off (BSM OFF indicator light in instrument panel illuminates) by pressing the switch. Although the system may detect objects on the road side such as parked vehicles or guardrails and operate the warning light/beep, it does not indicate a malfunction. If the vehicle is driven on a road with less traffic and few vehicles that the radar sensors can detect, the system may pause (The BSM OFF indicator light in the instrument panel flashes). However, it does not indicate a malfunction. l l l l l l l l l l l 5-34
