Hill Descent Assistant
Read and observe
and
The hill descent assistant (hereinafter referred to as assistant), with its auto-
matic braking action on all wheels, ensures a constant speed on a steep slope
when driving forwards and reversing.
During an intervention of the Assistants, the warning light
strument cluster.
The assistant is automatically engaged under the following conditions.
The engine is running.
For vehicles with Manual transmission the shift lever is in the neutral po-
sition and or the 1st, 2nd, 3rd gear, or reverse gear is engaged.
On vehicles with an automatic transmission, the selector lever is in the R,
N, D, S position or in the Tiptronic position.
The downhill gradient is at least 10 % (when driving over sleepers, the lim-
it can briefly drop to 8 %).
Neither the accelerator nor the brake pedal is operated.
Driving speed
Initiate the downhill decent at a reasonable speed up to 30 km / h the hill de-
scent assist maintains this speed when driving downhill constant.
The assistant can maintain constant speed of about 2 - 30 km / h.
If a forwards or reverse gear is engaged for vehicles with Manual transmis-
sion, the speed must be high enough to avoid stalling the engine.
By pressing the accelerator or brake pedal, the speed can be increased or re-
duced. This is true even if the shift lever is in the neutral position and the se-
lector lever in the N position. The engagement of the assistant is resumed af-
ter the pedal is released.
WARNING
For the correct operation of the assistant the road surface must be suffi-
ciently adherent. The assistant cannot properly fulfil its function on slushy
soil due to physical reasons (e.g. ice or mud). - there is a risk of an accident!
