2011 MERCEDES-BENZ SLK55AMG transmission

The current program mode appears in the
multifunction display.
:
Program mode indicator
You should only change the program mode
when the automatic transmission is in park
position P.
Automatic program mode S will not be stored.
When the engine is turned off with the
automatic program mode S selected, the
automatic transmission will go to the
automatic program mode C when the engine
is restarted.
X Press the program mode selector switch
repeatedly until the letter of the desired
program mode appears in the multifunction
display.
Selecting program mode C means:
R The vehicle starts out more gentle, both
forward and reverse, except when driving
off with full throttle.
R Traction and driving stability are improved
on icy roads.
R Upshifts occur earlier even when you give
more gas. The engine then operates at
lower revolutions and the wheels are less
likely to spin.
Selecting program mode S means that
upshifts occur later. One-touch gearshifting
With the automatic transmission in drive
position D and driving in automatic program mode
C or S, you can limit or extend the gear
range using the gear selector lever or the
steering wheel gearshift control.

You cannot shift with the steering wheel
gearshift control when the automatic
transmission is in park position P, neutral
position N, or reverse gear R.

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.

To avoid overrevving the engine when
downshifting, the automatic transmission
will not shift into a lower gear if the engine’s
maximum speed would be exceeded.
Extending gear range X
Briefly press the gear selector lever to the
right in the D+ direction.
or

The automatic transmission will shift into
the next higher gear as permitted by the
shift program. This action simultaneously
extends the gear range of the automatic
transmission.
i If you press on the accelerator pedal
when the engine has reached the
revolution limit of the current gear range,
the automatic transmission will upshift
beyond any gear range limit selected.
Canceling gear range limit X
Press and hold the gear selector lever to
the right in the D+ direction until D
reappears in the multifunction display.
or
X Pull and hold right gearshift control ; until
D reappears in the multifunction display.
The automatic transmission will shift from

position D.
Shifting into optimal gear range X
Press and hold the gear selector lever to
the left in the D- direction.
or
X Pull and hold left gearshift control :.
The automatic transmission will select the
gear range suited for optimal acceleration
and deceleration automatically. This will
involve shifting down one or more gears. Manual shift program
The manual shift program is available on
vehicles with AMG Sport Package and on
SLK 55 AMG only.
Manual program mode M differs with regard
to spontaneity, response time, and shifting
smoothness from automatic program mode
S.
In manual program mode M, system-
controlled automatic gearshifting is switched
off. You need to change the gears by manually
upshifting or downshifting using the gear
selector lever or the steering wheel gearshift
control. Program mode selector switch on vehicles with

Upshifting !
In manual program mode M, the
automatic transmission will not upshift,
even if the engine has reached its
overrevving range. Shift up into the next
gear before the engine has reached its
overrevving range. Make absolutely certain
that the engine speed does not reach the
red marking on the tachometer. Otherwise
the engine could be damaged which is not
covered by the Mercedes-Benz Limited
Warranty.

symbol ^ may appear instead of manual
program mode symbol M in the multifunction
display. Thus you can drive at the maximum
engine speed for each gear without
overrevving the engine.
X Shift the automatic transmission from
current gear : into the next higher gear.
The fuel supply will otherwise be
interrupted to prevent the engine from
overrevving.
Downshifting G
