Starting-off and driving
124
The automatic transmission performs automatic gear changes.
The modes of the automatic transmission can be adjusted by the driver by
means of the selector lever.
WARNING■ No throttle when it is set before starting the mode for moving forward
with the selector lever - there is a risk of accident!■
Never move the selector lever to mode R or P when driving – risk of an
accident!
■
If the vehicle is in the mode selected D, S , R or Tiptronic and the engine
stops when at idle speed, then the brake pedal must be pressed. Even
when the engine is idling, the power transmission is never completely in-
terrupted – the vehicle creeps.
■
When leaving the vehicle, the selector lever is always to put in the P
mode. Otherwise, the vehicle could be set in motion - risk of accident!
CAUTION
■ If the selector lever is moved to mode N while driving, the accelerator pedal
must be released and you will need to wait until the engine has reached its
idling speed before moving the selector lever to a forward driving mode again.■
When the outdoor temperature is below -10 ° C, the selector lever when
starting must always be in P mode.
■
When stopping on a slope, never try to hold the vehicle using the accelerator
pedal – this may lead to gear damage.
Note
After the ignition is switched off, the ignition key can only be withdrawn if the
selector lever is in the position P.Modes and use of selector leverFig. 136
Selector lever/display
Read and observe and on page 122 first.
When the ignition is switched on, the gearbox mode and the currently selected
gear are indicated in the display » Fig. 136.
The following modes can be selected with the selector lever » Fig. 136.
P
– Parking mode
The driven wheels are locked mechanically in this mode.
The parking mode must only be selected when the vehicle is stationary.
R
- Reverse gear
Reverse gear can only be engaged when the vehicle is stationary and the en-
gine is at idling speed.
N
- Neutral
The power transmission to the drive wheels is interrupted in this mode.
D
- Mode for forwards travel (normal programme)
In mode D, the forward gears are automatically changed according to the en-
gine load, accelerator pedal actuation and driving speed.
S
- Mode for forwards travel (sports programme)
In mode S , the forward gears are shifted automatically up and down at high-
er engine speeds than in mode D.
Before changing to mode S from mode D, press the lock button in the direction

Fault in the automatic gearbox
A fault in the automatic gearbox can, for example, be noticeable by the follow-
ing.
▶ Only certain gears are selected.
▶ The reverse gear R cannot be used.
▶ Shifting gears in Tiptronic mode is not possible.
CAUTION
If an error occurs on the automatic transmission the help of a specialist firm
should be sought immediately - there is a risk of damaging the vehicle.
Selector lever lock
Fig. 137
Shift lock button
Read and observe and on page 122 first.
The selector lever is locked in mode P and N to prevent that the forward driv-
ing is selected accidentally, thereby setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light
.
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.
Releasing selector lever from mode P or N (selector lever lock)
›
Press the brake pedal and the lock button at the same time in the direction
of
1
» Fig. 137 .
Just depress the brake pedal, if you would like to change from the mode N to
D .
Defective selector lever lock
If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be unlocked specially » page 195.
Note
If you want to move the selector lever from mode P to mode D or vice versa,
move the selector lever quickly. This prevents that you accidentally select
mode R or N.
Manual shifting of gears (Tiptronic)
Fig. 138
Selector lever
Read and observe and on page 122 first.
Tiptronic mode makes it possible to manually shift gears on the selector lever.
This mode can be selected both while stopping and while driving.
The currently selected gear is indicated in the display » Fig. 136 on page 122 .
The gearshift indicator should be observed when changing gear » page 40.

123Starting-off and Driving

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.
