Driving systems The DISTRONIC PLUS has not yet detected the vehicle changing lanes. There will be insufficient distance to the lane-changing vehicle. Narrow vehicles Cross-traffic 341 Because of their narrow profile, the vehicles traveling near the outer edges of the lane have not yet been detected by the DISTRONIC PLUS. There will be insufficient distance to the preceding vehicles. Obstacles and stationary vehicles The DISTRONIC PLUS may inadvertently detect crossing vehicles. If you switch on the DISTRONIC PLUS, for example, at a traffic light with cross traffic, the vehicle may suddenly start to drive off. Hill-start assist system On uphill grades, the hill-start assist system maintains the pressure in the brake system for approximately 1 second after you have released the brake pedal. Therefore, you can start off smoothly without the vehicle moving immediately after releasing the brake pedal. G Warning! The DISTRONIC PLUS does not brake for obstacles or stationary vehicles. If, for example, the vehicle detected in front of you changes lanes to bypass an obstacle or stationary vehicle in front of it, the DISTRONIC PLUS will not brake for the obstacle or stationary vehicle.
