Automatic transmission
Automatic transmission
Information on driving with an automatic
transmission is found in the “Getting start-
ed” section (
page 43).
Your transmission adapts its gear shifting
process to your individual driving style by
continually adjusting the shift points up or
down. These shift point adjustments are
performed based on current operating 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 selector lever positionD with gear
ranges4, 3, 2, 1 (
page 145)
the selected shift program (C/S)
(page 147)
the position of the accelerator pedal
(page 148)
the vehicle speed
The current selector lever position and
shift program (
C/S) appear in the tachom-
eter display (
page 22). When the selector lever is in positionD,
you can influence transmission shifting by:
limiting the gear range
changing gears manually
iDuring the brief warm-up the transmis-
sion upshifting is delayed. This allows
the catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
It is dangerous to shift the 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 en-
gine is idling normally and when your right
foot is firmly on the brake pedal.
144 Controls in detailAutomatic transmissionOne-touch gearshifting
Even with an automatic transmission you
can change the gears manually when the
selector lever is in positionD.
Downshifting
Briefly press the selector lever to the
left in the D–direction.
The transmission will shift from the current
gear to the next lower gear. This action si-
multaneously limits the gear range of the
transmission (
page 145).Upshifting
Briefly press the 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 selector lever in the
D+direction until
D reappears in the ta-
chometer display.
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 vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.
iTo avoid overrevving the engine when
the 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.

Automatic transmission
Steering wheel gearshift control
(Speedshift) and manual shift program CL 55 AMG
The CL 55 AMG can be driven in both the
automatic and manual shift program
modes. In the manual shift program mode
you can change the gears manually on the
steering wheel or by using the selector le-
ver.
1Right button: upshift
2Left button: downshiftTo do so, you must first select the manual
shift program M on the program mode se-
lector switch.
3Program mode selector switch
S Sport For standard driving
C Comfort For comfort driving
M Manual For manual gear shiftingActivating steering wheel gearshift
control
Press the program mode selector
switch repeatedly until the
M for manual
shift program appears in the tachome-
ter display.
Automatic gear shifting is activated.
!Never change the program mode when
the selector lever is out of positionP. It
could result in a change of driving char-
acteristics for which you may not be
prepared.
350 Technical termsMON
(M

The Motor Octane Number for gasoline
as determined by a standardized meth-
od. It is an indication of a gasoline's
ability to resist undesired detonation
(knocking). The average of both the
MON (Motor Octane Number) and
->RON (Research Octane Number) is
posted at the pump, also known as AN-
TI-KNOCK INDEX.

Display field in the speedometer used
to present information provided by the
control system.
Multifunction steering wheel
Steering wheel with buttons for operat-
ing the control system.

Engine speeds within the red marking
of the tachometer dial. Avoid this en-
gine speed range, as it may result in se-
rious engine damage that is not
covered by the Mercedes-Benz Limited

signals to assist the driver during park-
ing maneuvers.
