Press program mode selector switch
repeatedly until the letter of the
desired program mode appears in the
multifunction display.
SelectCfor comfort driving
(R 63 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.
SelectSfor standard driving
(R 63 AMG: sporty driving):

The vehicle starts out in first gear.

Upshifts occur later.
Steering wheel gearshift control
With drive positionD selected and driving
in program modeC or S, you can limit or
extend the gear range.
If your vehicle is equipped with manual
shift programM, you can use the steering
wheel gearshift control to manually shift
the gears.
1Left shift button: limiting gear range or
downshift (in program modeM)
2Right shift button: extending gear
range or upshift (in program modeM)
The following instructions describe opera-
tion of the steering wheel gearshift control
when driving in program modeC or S.
iR63AMG:
For information on using the steering wheel gear-
shift control in program modeM, see “Manual
shift program (R 63 AMG only)” (
page 209).
!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 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.iYou cannot shift with the steering wheel
gearshift control buttons when the transmission
in positionP,N orR.

Automatic transmission
Limiting gear range
Briefly press left shift button1.
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 205).Extending gear range
Briefly press right shift button2.
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 limitPress and hold right shift button2
until the cipher for the current gear
range disappears from the multifunc-
tion display (
page 205).
The transmission will shift from the
current gear range directly to gear
rangeD.
Shifting into optimal gear range
Press and hold left shift button1.
The transmission will automatically
select the gear range suited for optimal
acceleration 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 down-
shifting, the transmission will not shift to a lower
gear if the engine’s max. speed would be
exceeded.
iIf you press on the accelerator when the en-
gine has reached its rpm limit, the transmission
will upshift beyond any gear range limit selected.

Upshifting
Briefly press right shift button2
(
page 207).
The transmission shifts to the next
higher gear.If you have selected the AMG menu in the
control system (
page 168) and you are
driving in the manual program modeM,
upshift indicator2 in the multifunction
display advises you to upshift before the
engine reaches the overspeed range. Thus
you can drive at the maximum engine
speed for each gear without overrevving
the engine.

2Upshift indicator
Shift to the next higher gear.
The fuel supply will otherwise be inter-
rupted to prevent the engine from over-
revving.Downshifting
Briefly press left shift button1
(
page 207).
The transmission shifts to the next
lower gear.
!In the manual program modeM, the trans-
mission will not upshift, even if the engine has
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 157). Otherwise the
engine could be damaged which is not covered
by the Mercedes-Benz Limited Warranty.
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.
iWhen you brake or stop, the transmission
shifts down to a gear from which you can easily
accelerate or drive off.
