164 Controls in detailAutomatic transmission
Automatic transmissionFor more information on driving with an au-
tomatic transmission, see the “Getting
started” section (
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:


the gear selector lever positionD with
gear ranges (
page 166)


the selected shift program (C/S)
(page 170)
or
(C/S/M) (S 55 AMG only)
(page 171)


the position of the accelerator pedal
(page 170)


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


limiting the gear range


changing gears manually
iDuring 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.

165 Controls in detail
Automatic transmission
One-touch gearshifting
Even with an automatic transmission you
can change the gears manually when the
gear selector lever is in positionD.
Downshifting
Briefly press the gear selector lever to
the left in the D-direction.
The transmission will shift from the current
gear to the next lower gear. This action
simultaneously limits the gear range of the
transmission (
page 166).Upshifting

Briefly press the gear selector lever to
the right in the D+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simulta-
neously extends the gear range of the
transmission.Canceling gear range limit

Press and hold the gear selector lever
in the D+ direction until
D reappears in
the tachometer display field.
The transmission will shift from the current
gear range directly to gear rangeD.
Shifting into optimal gear range

Press and hold the gear selector lever
in the D-direction.
The transmission will automatically select
the gear range suited for optimal accelera-
tion and deceleration. This will involve
shifting down one or more gears.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced
vehicle control. Your vehicle’s ABS will not
prevent this type of loss of control.
iTo avoid overrevving the engine when
the gear selector lever is moved to the
D-direction, the transmission will not
shift to a lower gear if the engine's
max. speed would be exceeded.

168 Controls in detailAutomatic transmission
Steering wheel gearshift control (Speedshift) S 55 AMG
You can change the gears manually on the
steering wheel or by using the gear
selector lever (
page 165).
Allow engine to warm up under low load
use. Do not place full load on the engine
until the operating temperature has been
reached. Shift into reverse gear only when
the vehicle is stopped.
!Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, positionP alone is not in-
tended to or capable of preventing your ve-
hicle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 45).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch, take the
SmartKey with KEYLESS-GO* with you and
lock your vehicle. Do not leave children un-
attended in the vehicle, or with access to an
unlocked vehicle. Children could move the
gear selector lever from positionP, which
could result in an accident and/or serious
personal injury.
!Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
is not covered by the Mercedes-Benz
Limited Warranty.

mode, only second gear and reverse gear
can be activated.
Stop the vehicle.

Move gear selector lever toP.

Turn off the engine.

Wait at least ten seconds before re-
starting.

Restart the engine.

Move gear selector lever to positionD
(for second gear) orR.

Have the transmission checked at an
authorized Mercedes-Benz Center as
soon as possible.
