For more information, see the “Controls in
detail” section (
page 173).Starting with the SmartKey

Make sure the gear selector lever is set
toP.

Do not depress accelerator.

Turn the SmartKey in the starter switch
to position3 and hold until the engine
starts (
page 34).

Depress the brake pedal.
The gear selector lever lock is released.
For information on turning off the engine
with the SmartKey, see “Turning off with
the SmartKey” (
page 57).
Warning!
G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas
(such as a garage) which are not properly
ventilated. If you think that exhaust gas
fumes are entering the vehicle while driving,
have the cause determined and corrected
immediately. If you must drive under these
conditions, drive with at least one window
fully open.
iYou can also use the “touch-start”
function. Turn the SmartKey to
position3 and release it again immedi-
ately. The engine then starts automati-
cally.

Automatic transmission
For more information on driving with an
automatic transmission, see “Automatic
transmission” (
page 46).
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
operating and driving conditions.
If the operating conditions change, the
automatic transmission reacts by
adjusting its shift program.
Gearshift pattern for automatic
transmission
The automatic transmission selects indi-
vidual gears automatically, depending on:

the gear selector lever
positionD(
page 177) with
gear ranges (page 176)


the selected program mode:
(C/S) (
page 179)
or
(M/C/S) (S 55 AMG only)
(
page 183)


the position of the accelerator pedal
(page 180)


the vehicle speed
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.

174 Controls in detailAutomatic transmission1Current gear range/gear selector lever
position
2Current program mode
The current gear range/gear selector lever
position and program mode (
C/S)
or (
M/C/S) appear in the tachometer
display.When the gear selector lever is in
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 ofP orN 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.
Shift into reverse gearR or parking
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.

175 Controls in detail
Automatic transmission
One-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 theD-direction.
The transmission will shift from the current
gear to the next lower gear as permitted by
the shift program. This action simulta-
neously limits the gear range of the
transmission (
page 176).Upshifting

Briefly press the gear selector lever to
the right in theD+direction.
The transmission will shift from the current
gear to the next higher gear as permitted
by the shift program. This action simul-
taneously extends the gear range of the
transmission.Canceling gear range limit

Press and hold the gear selector lever
in theD+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 theD-direction.
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
the gear selector lever is moved to
theD-direction, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.

176 Controls in detailAutomatic transmissionGear 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 appears in the
tachometer display (
page 174). 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 to
vehicles with 7-speed automatic
transmission only).
î
The transmission shifts through
fifth gear only (applies to
vehicles with 7-speed automatic
transmission only).
é
The transmission shifts through
fourth gear only.
è
The transmission shifts through
third gear only.
With this selection you can use
the braking effect of the engine.
Effect
ç
The transmission shifts through
second gear only.
Allows the use of engine’s
braking power when driving:

on steep downgrades


in mountainous regions


under extreme operating
conditions
æ
The transmission operates in
first gear only.
For maximum use of engine’s
braking effect on very steep or
lengthy downgrades.
