G WARNING The distance warning function cannot always clearly identify objects and complex traffic situations. may: R give an unnecessary warning R not give a warning There is a risk of an accident. uation and do not rely solely on the distance warning function. X Brake immediately in order to increase the distance from the vehicle in front. or X Take evasive action, provided it is safe to do so. Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause the system to display a warning. Autonomous braking function If the driver does not react to the distance warn- ing signal in a critical situation, COLLISION PRE- VENTION ASSIST PLUS can assist with the autonomous braking function. The autonomous braking function: R gives the driver more time to react to critical driving situations R can help the driver to avoid an accident or R reduces the effects of an accident The autonomous braking function is available in the following speed ranges: R from 4 mph (7 km/h) to approx. 65 mph (105 km/h) for moving objects R from 4 mph (7 km/h) to approx. 31 mph (50 km/h) for stationary objects Due to the nature of the system, particularly complicated but non-critical driving conditions may also cause the Autonomous Braking Func- tion to intervene. If the autonomous braking function requires a particularly high braking force, preventative passenger protection measures (PRE-SAFE ® ) are activated simultaneously ( Y page 59). Adaptive Brake Assist General information i Observe the "Important safety notes" sec- tion ( Y page 68). With the help of adaptive Brake Assist, the dis- tance warning signal can detect obstacles that are in the path of your vehicle for an extended period of time. If adaptive Brake Assist detects a risk of colli- sion with the vehicle in front, it calculates the braking force necessary to avoid a collision. If you apply the brakes forcefully, adaptive Brake Assist will automatically increase the braking force to a level suitable for the traffic conditions. Adaptive Brake Assist provides braking assis- tance in hazardous situations at speeds above 4 mph (7 km/h). It uses radar sensor technology to assess the traffic situation. Up to a speed of approximately 155 mph (250 km/h), Adaptive Brake Assist is capable of reacting to moving objects that have already been detected as such at least once over the period of observation. Up to a speed of approximately 44 mph (70 km/h), Adaptive Brake Assist reacts to sta- tionary obstacles. If adaptive Brake Assist demands particularly high braking force, preventative passenger pro- tection measures (PRE-SAFE ® ) are activated simultaneously ( Y page 59). X Keep the brake pedal depressed until the emergency braking situation is over. ABS prevents the wheels from locking. The brakes will work normally again if: R you release the brake pedal. R there is no longer any danger of a collision. R no obstacle is detected in front of your vehi- cle. Adaptive Brake Assist is then deactivated.
