So that an engagement of the OFF ROAD mode can take place, the following
conditions must be met.
The OFF ROAD mode is enabled.
The vehicle is moving at a speed of less than 30 km/h. The warning light
illuminates in the instrument cluster.
The following functions are integrated in the OFF ROAD mode.
▶ Downhill Drive Support » page 130.
▶ TCS OFF ROAD » page 130.
▶ EDL OFF ROAD » page 130.
▶ ABS OFF ROAD » page 130.
▶ Start-Off Assistant » page 131.
Note
If the engine stalls while driving and is started again within 30 seconds, then
OFF ROAD mode will be automatically activated.
Hill Descent Assistant
Read and observe
and on page 129 first.
The hill descent assistant (hereinafter referred to as assistant), with its auto-
matic braking action on all wheels, ensures a constant speed is maintained on
a steep slope when driving forwards and reversing.
During an intervention of the Assistants, the warning light flashes in the in-
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.WARNINGFor 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!
Note
During an active intervention of the assistant, the brake lights do not light up.
TCSOFF ROAD
Read and observe
and on page 129 first.
The ASR OFF ROAD makes starting and driving on an unpaved surface easier
as it partially allows wheel-spin.
Note
When disabled, the TCS » Fig. 140 on page 127 OFF ROAD mode works without
the support of the TCS OFF ROAD.
EDS OFF ROAD
Read and observe
and on page 129 first.
The EDS supports OFF ROAD vehicle traction when driving on a surface withdifferent grip under the drive wheels or when driving over bumps.
A spinning wheel or wheels are braked earlier and with more force than with
the intervention of the standard EDS system.
ABS OFF ROAD
Read and observe
and on page 129 first.
The ABS OFF ROAD supports the driver when braking on an unpaved surface
such as gravel, snow, etc.
