Safety and security Driving safety systems G Warning! BAS Plus is a convenience system designed to assist the driver during vehicle operation. The responsibility for the vehicle speed and the distance to the vehicle ahead, including most importantly brake operation to assure safe stopping distance, always remains with the driver. Always pay attention to traffic conditions even while BAS Plus is switched on. Otherwise, you may not be able to recognize dangerous situations until it is too late and could cause an accident resulting in personal or fatal injury to you or others. i This device has been approved by the FCC as a "Vehicular Radar System". The radar sensor is intended for use in an automotive radar system only. Removal, tampering, or altering of the device will void any warranties, and is not permitted by the FCC. Do not tamper with, alter, or use in any non-approved way. Any unauthorized modification to this device could void the user's authority to operate the equipment. BAS Plus detects obstacles that are in your driving path for a sufficient period of time to permit the system to recognize these obstacles. If you approach the detected obstacle quickly, BAS Plus calculates the level of brake power boost appropriate for the circumstance to supply when the driver applies the brakes. When you step quickly on the brake pedal in an emergency braking situation, BAS Plus automatically regulates the brake power boost to a level that is suitable for the traffic situation. If BAS Plus requires a particularly high brake power boost, PRE-SAFE® is activated at the same time. X Keep constant pressure on the brake pedal until the emergency braking situation is over. During this process, the ABS prevents the wheels from locking up. The brakes will resume normal operation after Rthe Rno BAS Plus can react to stationary obstacles such as standing or parked vehicles at road speeds of up to approximately 40 mph (70 km/h). BAS Plus can only assist you when the radar sensors are switched on and functional. You can check whether the sensors are active by switching on DISTRONIC Plus (Y page 350) or using the Radar sensors function (Y page 247) in the instrument cluster control system. brake pedal is released obstacles are detected in your path Rthe system no longer senses a risk of a collision BAS Plus is then deactivated. G Warning! BAS Plus will only respond with brake assistance if it has clearly detected an object. Detection can be impeded by Rdirty or covered sensors Rsnowfall or heavy rain Rdisturbance from other radar sources Rstrong radar reflection such as in parking garages BAS Plus uses radar signals that are not reflected well by narrow objects and absorptive materials. For this reason BAS Plus will not react to persons, animals, and approaching traffic or cross-traffic. BAS Plus may not detect narrow vehicles driving in front of you, such as motorcycles Z 67
