Automatic transmission
Automatic transmission
For more information on driving with an au-
tomatic transmission, see the “Getting
started” section (
page 45).
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
automatic transmission reacts by adjust-
ing its gear shift program.The automatic transmission selects indi-
vidual gears automatically, depending on:
the gear selector lever positionD with
gear ranges (
page 159)
the selected shift program (C/S)
(page 163)
or
(C/S/M) (CL 55 AMG only)
(page 164)
the position of the accelerator pedal
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 le-
ver out of P or N if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate 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.

158 Controls in detailAutomatic transmissionOne-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 si-
multaneously limits the gear range of the
transmission (
page 159).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.
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 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.

Gear ranges
With the gear selector lever in positionD,
you can limit the transmission’s gear range
by pressing the gear selector lever to the
left (D-), and reverse the gear range limit
by pressing the gear selector lever to the
right (D+).
The selected gear range will appear in the
tachometer display. If you press on the
accelerator when the engine has reached
its rpm limit, the transmission will upshift
beyond any gear range limit selected.
Effect
ï
The transmission shifts through
sixth gear only (applies only to
vehicles with 7-speed automatic
transmission).
î
The transmission shifts through
fifth gear only (applies only to ve-
hicles with 7-speed automatic
transmission).
é
The transmission shifts through
fourth gear only.
è
The transmission shifts through
third gear only.
With this selection you can use

ing power when driving

ditions
æ
The transmission operates in
first gear only.
For maximum use of engine’s

S Sport For standard driving
C Comfort For comfort driving
Press program mode selector
switch1 repeatedly until the letter of
the desired shift program appears in
the tachometer display (
page 22).
SelectCfor comfort driving:
The vehicle starts out in second
gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.
Traction and driving stability are
improved on icy roads.
Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.
The power transmission ratio for
gear selector lever positionR
changes depending on the program
mode selected (SorC).
Accelerator position
Your driving style influences the
transmission’s shifting behavior:
Less throttle Earlier upshifting
More throttle Later upshifting
Kickdown
Use kickdown when you want maximum
acceleration.
Press the accelerator past the point of
resistance.
The transmission shifts into a lower
gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.
!Never change the program mode when
the gear selector lever is out of
positionP. This could result in a
change of driving characteristics for
which you may not be prepared.
