ANeutral
Do not shift the transmission toi
while driving. Otherwise, the auto-
matic transmission could be dam-
aged.
No power is transmitted from the
engine to the drive wheels.
Releasing the brake pedal will allow
you to move the vehicle freely, e.g. to
push it or tow it.
If ESP
®is deactivated or faulty: shift
the transmission to position iif the
vehicle is in danger of skidding, e.g.
on icy roads.
If you switch the engine off with the
transmission in position korh,
the automatic transmission shifts to
i automatically.
!Coasting in neutral imay
cause damage to the drive train.
7Drive
The automatic transmission changes
gear automatically. All forward gears
are available.
Driving tips
Changing gear
The automatic transmission shifts through the
individual gears automatically when it is in trans-
mission position h. This automatic gear shift-
ing behavior is determined by:
Rthe selected drive program
Rthe position of the accelerator pedal
Rthe road speed
Accelerator pedal position
Your style of driving influences how the auto-
matic transmission shifts gear:
Rlittle throttle: early upshifts
Rmore throttle: late upshifts
Double-clutch function
When shifting down, the double-clutch function
is active regardless of the currently selected
drive program. The double-clutch function reduces load change reactions and is conducive
to a sporty driving style. The sound generated by
the double-clutch function depends on the drive
program selected.
Kickdown
Use kickdown for maximum acceleration.
XDepress the accelerator pedal beyond the
pressure point.
The automatic transmission shifts to a lower
gear depending on the engine speed.
XEase off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Gliding mode
Gliding mode is available depending on equip-
ment.
Gliding mode is characterized by the following:
RThe combustion engine is disconnected from
the drive train.
RThe engine speed corresponds to the idling
speed.
RThe multifunction display hides the gear indi-
cator and displays transmission position h
in green (
