To pull away from the neutral position, you can
only shift into 1st or 2nd reverse gear.
When shifting into reverse gear, the manual drive
program is activated. You can switch to the auto‐
matic shift program.

position:
#
depress the brake pedal or apply the parking
brake.
#

Overview of touch-key gearshift and gear dis‐
play
* NOTE Damage to the gearbox due to roll‐
ing in neutral position
In neutral position, avoid allowing the vehicle
to roll for a relatively long distance.
If the continuous brake (engine brake/
retarder) is switched on, the engine speed for
a downshift is higher than when the continu‐
ous brake is switched off.
Allowing the wheels to roll for a relatively long
distance, e.g. during towing, causes transmis‐
sion damage.
#
Only allow the vehicle to roll in the neu‐
tral position of the transmission for a
short time.
Observe the event messages of the on-board
computer which indicate special operating sta‐
tuses and help to avoid damage to the automatic
transmission.
The automatic transmission is equipped with a
touch-key gearshift. The touch-key gearshift is
next to the driver's seat on the engine tunnel.
The individual gears are selected automatically
depending on the following parameters:
R
Shift range
R
Speed
R
accelerator pedal position
R
drive program
R
engine brake and/or retarder
You can limit or extend the shift range at any
time.
