Automatic transmission
For more information on driving with an
automatic transmission, see “Automatic
transmission” (
page 53).
Your vehicle’s transmission adapts its gear
shifting process to your individual driving
style by continually adjusting the shift
points up or down. These shift point adjust-
ments are performed based on current
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.

The gear selector lever is located on the
lower part of the center console.

iDuring the brief warm-up, transmission
upshifting is delayed. This allows the catalytic
converter to heat up more quickly to operating
temperature.
Warning!G
Make sure that absolutely no objects are
obstructing the pedals’ range of movement.
Keep the driver’s footwell clear of all obsta-
cles. If there are any floormats or carpets in
the footwell, make sure that the pedals still
have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.

Setting the following distance in
Distronic
You can set the specified following dis-
tance for Distronic by varying the time set-
ting between 1.0 and 2.0 seconds. Using
this time setting and the current speed of
your vehicle, Distronic calculates and sets
the required following distance to the
preceding vehicle. The set distance will
appear in the right multifunction display
(
page 222).
The distance setting thumbwheel for the
time setting is located on the lower section
of the center console.1Thumbwheel for setting following
distanceIncreasing distance
Increasing the distance setting tells
Distronic to maintain a greater following
distance to the preceding vehicle.
Turn thumbwheel1 towards ¯.
Decreasing distance
Decreasing the distance setting tells
Distronic to maintain a shorter following
distance to the preceding vehicle.
Turn thumbwheel1 towards ®.
!Moving the gear selector lever to positionN
while driving cancels the Distronic. However, the
gear selector lever should not be moved to
positionN while driving except to coast when
the vehicle is in danger of skidding (e.g. on icy
roads).
iDepressing the accelerator pedal does not
deactivate the Distronic. After brief acceleration
(e.g. for passing), the Distronic will resume the
last speed set.
Warning!G
It is up to the driver to exercise discretion to
select the appropriate setting given road
conditions, traffic, driver’s preferred driving
style and applicable laws and driving recom-
mendations for safe following distance.

As your vehicle approaches an object, one
or more distance segments will illuminate,
depending on the distance. When the
eighth distance segment illuminates, you
have reached the minimum distance.

Front area: An intermittent acoustic
warning will sound as the first red
distance segment illuminates and a
constant acoustic warning lasting a
maximum of 2 seconds will sound for
the second distance segment.
The signal is canceled when the gear
selector lever is placed in position P or
the parking brake is set.

Rear area: An intermittent acoustic
warning will sound when the first dis-
tance segment illuminates. This signal
quickens with each additional distance
segment lit. When the eighth distance
segment illuminates, the acoustic
warning becomes a constant signal.
The signal is canceled when the gear
selector lever is placed in positionD
