Safety and Security Driving safety systems BAS Warning! The Brake Assist System (BAS) operates in emergency situations. If you apply the brakes very quickly, the BAS automatically provides full brake boost, thereby potentially reducing the braking distance. 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. Warning! When you step quickly on the brake pedal in an emergency braking situation, BAS Plus automatically regulates the brake pressure to a level that is suitable for the traffic situation. If BAS Plus requires a particularly high brake pressure, PRE-SAFE® is activated at the same time. Step on the brake pedal until the emergency braking situation is over. During this process, ABS prevents the wheels from locking up. Once you take your foot off the brake pedal or when there is no longer a risk of collision, the brake pedal functions again as usual. BAS Plus is deactivated. EBP The Electronic Brake Proportioning (EBP) enhances braking effectiveness by allowing the rear brakes to supply a greater proportion of the braking effort in straight line breaking without a loss of vehicle stability. G The BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. The BAS cannot prevent accidents, including those resulting from excessive speed in turns, following another vehicle too closely, or hydroplaning. Only a safe, attentive, and skillful driver can prevent accidents. The capabilities of a BAS equipped vehicle must never be exploited in a reckless or dangerous manner which could jeopardize the user's safety or the safety of others. G When the BAS is malfunctioning, the brake system is still functioning normally, but without the additional brake boost available that BAS would normally provide in an emergency braking maneuver. Therefore, the braking distance may increase. For more information, see "Practical hints" section ( page 544). BAS Plus* BAS Plus operates in emergency braking situations and uses radar sensors to assess the traffic situation. 71
