Reverse gear
Only engage reverse gear when the vehicle
is stationary and the engine is at idling
speed.

Drive position
The automatic transmission shifts all six
forward gears automatically. The drive posi-
tion will provide optimal driving characteris-
tics in almost all operating circumstances.

Drive programs
The automatic transmission offers the Econ-
omy and Power drive programs. The drive
programs support your desired driving style.
The Economy standard drive program is
designed for a comfortable, economic driving
style and makes driving on slippery road surfa-
ces easier.
The Power drive program is for travelling at
higher engine speeds and for greater perform-
ance requirements. Only choose the Power
drive program when necessary, and then only
for a short period. Otherwise, the fuel con-
sumption is increased.
After starting the engine, the standard drive
program Economy is always active.
You can switch between the drive programs at
any time:

If the transmission oil temperature falls
below 23 ‡ (−5 †) the automatic transmis-
sion has cooled down. The transmission
electronics then only engage the reverse
gear or second forward gear. If the trans-
mission oil temperature exceeds 23 ‡
(−5 †) the transmission electronics will
shift to all gears once again.
Stopping
!
Only let the vehicle coast briefly in neutral
position. Extended coasting of the wheels
results in transmission damage, e.g. when
towing away.
If the continuous brake (engine brake/
retarder) is activated, the engine speed for
downshifting is higher than when the contin-
uous brake is deactivated.
When stopping briefly, e.g. at traffic lights:
X
Maintain the gear position and stop the
vehicle with the service brake.
When stopping for a longer period with the
engine running:
X
Shift the transmission to neutral position.
