ness of the ambient light. A chime sounds if the radar sensors have already detected vehicles when the driver activates the turn signal. If a vehicle comes into the detection zone after the driver activates the turn signal, then only the BSW indicator light flashes and no chime sounds. (See "BSW driving situations" (P.5-20).) The BSW system is automatically turned on when the engine is started and the BSW ON 1 illuminates on the switch. You indicator light * can turn the BSW system off by pushing the BSW switch on the instrumental panel. NOTE: If you continue to push the BSW switch from off to on for over 4 seconds, a chime will sound. This will change the default status of the BSW system to OFF so that this system will not automatically turn on when the engine is started. If this procedure is repeated, the default status will return to ON. . Excessive noise (for example, audio system volume, open vehicle window) will interfere with the chime sound, and it may not be heard. The radar sensors may not be able to detect and activate BSW when certain objects are present such as: - Pedestrians, bicycles, animals - Several types of vehicles such as motorcycles - Oncoming vehicles - Vehicles remaining in the detection zone when you accelerate from a stop (See "BSW driving situations" (P.5-20).) - A vehicle merging into an adjacent lane at a speed approximately the same as your vehicle (See "BSW driving situations" (P.5-20).) - A vehicle approaching rapidly from behind. (See "BSW driving situations" (P.520).) - A vehicle which your vehicle overtakes rapidly. (See "BSW driving situations" (P.5-20).) Severe weather or road spray conditions may reduce the ability of the radar to detect other vehicles. . . . The radar sensors detection zone is designed based on a standard lane width. When driving in a wider lane, the radar sensors may not detect vehicles in an adjacent lane. When driving in a narrow lane, the radar sensors may detect vehicles driving two lanes away. The radar sensors are designed to ignore most stationary objects, however objects such as guardrails, walls, foliage and parked vehicles may occasionally be detected. This is a normal operating condition. WARNING . Do not use the BSW system when towing a trailer because the system may not function properly. . Starting and driving 5-19
