First read and observe the introductory information
and safety warnings
The downhill driving assistant in vehicles with an automatic gearbox helps when braking and travelling downhill . The downhill driving assistant uses the braking power of the engine.
The automatic gearbox selects the best gear for the circumstances by taking the steepness of the hill and the current speed into consideration. To do this the selector lever must be in position D or S. The downhill driving assistant is not active in Tiptronic mode.
As the downhill driving assistant can only shift down as far as the 3rd gear, it may be necessary to activate the Tiptronic mode when driving down particularly steep inclines. When in Tiptronic mode, select the 2nd or 1st gear manually in order to make use of the braking effect of the engine and to relieve the brakes.
