The automatic transmission changes
gear automatically in the automatic
drive programs (Y page 122). 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 005B. This automatic gear shift-
ing behavior is determined by:
R the selected drive program (Y page 116)
R the position of the accelerator pedal
R the road speed
Accelerator pedal position Your style of driving influences how the auto-
matic transmission shifts gear:
R little throttle: early upshifts
R more throttle: late upshifts
A dynamic driving style with high longitudinal
and lateral acceleration delays the shift points
to higher engine speeds. 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:
X In the automatic drive programs, depress the
accelerator pedal beyond the pressure point.
Depending on the engine speed and the selec- ted drive program, the automatic transmis-
sion shifts to the lowest gear permissible to
give optimal acceleration.
X Ease off the accelerator pedal once the
desired speed is reached.
The automatic transmission shifts back up.
Kickdown is not available in manual mode M.
Rocking the vehicle free Rocking the vehicle free may help to free the
vehicle if it has become stuck in slush or snow. To do so, shift back and forth repeatedly
between transmission positions 005Band 005E.
The vehicle's transmission management
restricts shifting between transmission posi-
tions 005Band 005Eto speeds up to a maximum of
5 mph (9 km/h).
To shift back and forth between transmission
positions 005Band 005E, move the E-SELECT lever
up and down beyond the pressure point.

Shifting gears
If you pull on the left-hand or right-hand steering
wheel paddle shifter, the automatic transmis-
sion switches to temporary manual drive pro-
gram for a limited amount of time. Depending on
which steering wheel paddle shifter is pulled,
the automatic transmission immediately shifts
into the next gear down or up, if permitted.
X To shift up: pull the right-hand steering wheel
paddle shifter (Y page 121).
The automatic transmission shifts up to the
next gear.
If the maximum engine speed in the currently
engaged gear is reached and you continue to
accelerate, the automatic transmission auto-
matically shifts up in order to prevent engine
damage.
The automatic transmission will not shift up to the next gear when the engine speed is very
low.
X To shift down: pull on the left-hand steering
wheel paddle shifter (Y page 121).
The automatic transmission shifts down to
the next gear.
If the engine were to exceed the maximum
engine speed when shifting down, the auto-
matic transmission protects against engine
damage by not shifting down.
Automatic down shifting occurs when coast-
ing.
When using kickdown, the automatic trans-
mission automatically shifts to a lower gear.
Deactivating If you have activated temporary manual drive
program, it will remain active for a certain
amount of time. Under certain conditions, the
minimum amount of time is extended, e.g. in the
case of lateral acceleration, during overrun
