Automatic transmission
Shifting procedure
The automatic transmission selects indi-
vidual gears automatically, depending on:

the gear selector lever drive position D
(
page 171) with gear ranges
(
page 174)

the selected shift program
(C/MAN/S)(
page 175)

the position of the accelerator pedal
(
page 173)

the vehicle speed
The current gear selector lever position
(
P/R/N/D), the gear range (1/2/3/4) and
the shift program (
C/M/S) are shown in the
standard display (
page 117).When the gear selector lever is in drive
positionD, you can influence transmission
shifting by:

limiting the gear range

changing gears manually
Warning!G
It is dangerous to shift the gear selector
lever out of park positionP or neutralN 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 engine is idling
normally and when your right foot is firmly
on the brake pedal.
!Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached
(
page 307).
Shift into park position P or reverse gearR 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.

Driving tips
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.
Depending on the engine speed the
transmission shifts into a lower gear.
Ease on the accelerator when you have
reached the desired speed.
The transmission shifts up again.Stopping
When you stop briefly, e.g. at traffic lights:
Leave the transmission in gear.
Hold the vehicle with the brake.
When you stop longer with the engine
idling and/or on a hill:
Set the parking brake.
Move the gear selector lever to park
positionP.Maneuvering
When you maneuver in tight areas,
e.g. when pulling into a parking space:
Control the vehicle speed by gradually
releasing the brakes.
Accelerate gently.
Never abruptly step on the accelerator.
Working on the vehicle
iKickdown in manual shift program MAN is
not possible.
In kickdown operation, it is not possible to
change gear with the steering wheel gear shift
buttons.
Warning!G
When working on the vehicle, set the
parking brake and move gear selector lever
to positionP. Otherwise the vehicle could
roll away.

Turn the program mode selector switch
to the desired setting.
The letter of the desired shift program
appears in the right multifunction

Select C for comfort driving:

The vehicle starts out in second
gear 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.Gear selector lever one-touch
gearshifting
With the gear selector lever in drive posi-
tion D and driving in shift programC orS,
you can limit or extend the gear range.
With the MAN shift program activated, you
can use the gear selector lever to manually
shift the gears.
The following instructions describe opera-
tion of the gear selector lever when driving
in the shift programC orS.
!Never change the program when the gear
selector lever is out of park positionP. This could
result in a change of driving characteristics for
which you may not be prepared.
iFor information on using the gear selector
lever in shift program MAN, see “Manual shift
program” (
page 179).
!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

Manual shift program
In addition to the shift programC orS,
your vehicle is equipped with the
MANshift program.
In the manual shift programMAN,
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 but-
tons/paddles (
page 177) or the gear
selector lever (
page 175).Activating manual shift program
Turn program mode selector switch1
(
page 175) to the MAN setting.
The transmission switches to the
manual program modeM. The letter
M
appears in the right multifunction dis-
play and the lamp in program mode se-
lector switch3 (
page 179) comes
on. Automatic shifting is switched off.
The gear range is not limited.
You can change the gears manually when
the gear selector lever is in drive
positionD. You can upshift or downshift
through the gears in succession.Selecting manual shift program mode

desired setting (I, II or III).
Downshifting
Briefly press left shift button1 or pull
the left shift paddle1 (
page 177).
or
Briefly press the gear selector lever to
the left in theD-direction.

higher gear.If the red gearshift indicator lamp>
comes on in the speedometer display
(
page 29), shift to the next higher gear.
The fuel supply will otherwise be interrupt-
ed to prevent the engine from overrevving.
Mercedes-Benz SLR McLaren 722 Edition:
If you have selected the 722 Edition menu
(
page 123) and up appears in the right
multifunction display in addition to the red
gearshift indicator lamp>, shift to the
next higher gear. The fuel supply will other-
wise be interrupted to prevent the engine
from overrevving.
Deactivating manual gearshift program
Turn program mode selector switch1
(
page 175) to the shift programC
orS.
The selected gearshift program ap-
pears in the right multifunction display.
iThe currently selected manual shift program
(I, II or III) does not appear in the right multifunc-
tion display. The current setting is indicated only
on the program mode selector switch 3.
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 take off.
!In the manual program modeM, the trans-
mission will not upshift, even if the engine has
reached its overrevving range. Shift up to the
n ext g ear bef ore t he en gi ne has reac hed i ts 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.
