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.

168 Controls in detailAutomatic transmissionAn additional indication of the current gear
selector lever position can be found on the
cover of the shifting-gate.When the gear selector lever is in
positionD, you can influence transmission
shifting by


limiting the shift range


changing gears manually
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 cur-
rent gear to the next lower gear. This
action simultaneously limits the gear
range of the transmission
(page 170).
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.

169 Controls in detail
Automatic transmission
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.
