Automatic transmission
Automatic transmission
For information on driving with an auto-
matic transmission, see the “Getting
started” section (
page 48).
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 gear shift program.
Gearshift patternThe automatic transmission selects indi-
vidual gears automatically, depending on:

the gear selector lever position D with
gear ranges 4, 3, 2 and 1 (
page 170)


the selected shift program mode
(C/MAN/S)(
page 173)


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
right multifunction display (
page 117).
iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
!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 301).
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.

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 right multifunction 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.

170 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
right multifunction display (
page 117). If
you press on the accelerator when the en-
gine has reached its rpm limit, the trans-
mission will upshift beyond any gear range
limit selected.
iIf, when driving in shift program mode
C and S the maximum engine speed for
the gear range has been reached, the
transmission shifts up automatically,
even if the gear range is restricted. In
shift program MAN the transmission
will not shift up automatically.
Effect
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 con-
ditions
æ
The transmission operates in the
first gear only.
For maximum use of engine’s
braking effect on very steep or
lengthy downgrades.

authorized Mercedes-Benz Center as
soon as possible.
!In the manual program modeM, the
transmission will not upshift, even if
the engine has reached its overrevving
range. Shift up to 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
(page 28). Otherwise the engine
could be damaged which is not covered
by the Mercedes-Benz Limited
Warranty.
