multifunction display.
1Current program mode

Press the program mode selector
switch repeatedly until the letter of the
desired program mode appears in the
multifunction display.
SelectC for comfort driving (S 63 AMG
and S 65 AMG: standard 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.SelectS for standard driving
(S 63 AMG and S 65 AMG: sporty driv-
ing):


The vehicle starts out in first gear.


Upshifts occur later.
!
Never change the program mode when the
automatic transmission is out of park positionP.
This could result in a change of driving character-
istics for which you may not be prepared.
i
The last selected program mode (CorS) is
switched on when the engine is restarted.

438 Controls in detailAutomatic transmissionSteering wheel gearshift control
With drive positionD selected and driving
in program modeC orS, you can limit or
extend the gear range.
If your vehicle is equipped with manual
shift program M, you can use the steering
wheel gearshift control to manually shift
the gears.

Allow engine to warm up under low load use.
Do not place full load on the engine until the op-
erating temperature has been reached.
Shift into reverse gearR or park positionP only
when the vehicle is stopped.
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.

Automatic transmission
Limiting gear range
Briefly press left shift button1 or pull
left shift paddle1.
The transmission will shift to the next
lower gear as permitted by the shift
program. This action simultaneously
limits the gear range of the transmis-
sion (
page 435).Extending gear range

Briefly press right shift button2 or
pull right shift paddle2.
The transmission will shift to the next
higher gear as permitted by the shift
program. This action simultaneously
extends the gear range of the transmis-
sion.Canceling gear range limit

Press and hold right shift button2 or
pull and hold right shift paddle2 until
the indicator for the current gear range
disappears from the multifunction dis-
play (
page 435).
The transmission will shift from the
current gear range directly to gear
rangeD.
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.i
To avoid overrevving the engine when down-
shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be ex-
ceeded.
i
If you press on the accelerator when the en-
gine has reached its rpm limit, the transmission
will upshift beyond any gear range limit selected.

440 Controls in detailAutomatic transmissionShifting into optimal gear range
Press and hold left shift button1 or
pull and hold left shift paddle1.
The transmission will automatically
select the gear range suited for optimal
acceleration and deceleration. This will
involve shifting down one or more
gears.Manual shift program (S 63 AMG and
S65AMGonly)
In addition to the automatic shift
programC orS, your vehicle is equipped
with the manual shift programM.
Manual shift programM differs with regard
to spontaneity, response time, and shifting
smoothness from automatic shift
programS.
In the manual program modeM,
system-controlled automatic gearshifting
is switched off and you need to change the
gears by manually upshifting or downshift-
ing using the steering wheel gearshift con-
trol paddles to the left and right of the
steering wheel (
page 438).

reached its overrevving range. Shift up to the
next gear before the engine has reached its over-
revving range. Make absolutely certain that the
engine speed does not reach the red marking on
the tachometer (
page 28). Otherwise the en-
gine could be damaged which is not covered by
the Mercedes-Benz Limited Warranty.


442 Controls in detailAutomatic transmissionIf you are driving in the manual program
modeM, upshift indicator2 in the multi-
function display advises you to upshift be-
fore the engine reaches the overspeed
