60 Driving safety systems BAS G Observe Safety notes, see page 59. The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS provides full brake boost automatically, thereby potentially reducing the braking distance. X Apply continuous full braking pressure until the emergency braking situation is over. The ABS will prevent the wheels from locking. When you release the brake pedal, the brakes function again as normal. The BAS is then deactivated. G Warning! If the BAS malfunctions, the brake system still functions, but without the additional brake boost available that the BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase. G Warning! Safety and security 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. Personal or fatal injury to you or others may be the result. BAS PLUS The Brake Assist System PLUS (BAS PLUS) operates in emergency braking situations and uses radar sensors to assess the traffic situation. BAS PLUS assists you in braking at speeds above approximately 20 mph (30 km/h). When traveling in Canada in a vehicle not registered in Canada, you must switch off the radar sensor system (Y page 126). Canadian law does not permit the use of the radar sensor system for vehicles from outside of Canada. When you switch off the radar system, the following functions are deactivated: RBAS PLUS Brake (Y page 63) PLUS (Y page 130) RPRE-SAFE® RDISTRONIC 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.
