̄ Automatic transmission
For more information on driving with an au-
tomatic transmission, see the “Getting
started” section (
୴ page 43).
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 op-
erating and driving conditions.
If the operating conditions change, the au-
tomatic transmission reacts by adjusting
its gear shift program.
The automatic transmission selects indi-
vidual gears automatically, depending on:
ț the gear selector lever position D with
gear ranges (
୴ page 166)
ț the selected shift program (C/S)
(
୴ page 170)
or
(C/S/M) (S 55 AMG only)
(
୴ page 171)
ț the position of the accelerator pedal
(

ț the vehicle speed
The current gear selector lever position
and shift program (
C
/
S
) or (
C
/
S
/
M
) appear
in the tachometer display (
୴ page 22).
When the gear selector lever is in
position D, you can influence transmission
shifting by:
ț limiting the gear range
ț changing gears manually

During the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning! G
It is dangerous to shift the gear selector
lever out of P or N if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickly forward or reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.
