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
simultaneously limits the gear range of the
transmission (
page 188).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 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 may
involve shifting down one or more gears.Steering wheel gearshift control
one-touch gearshifting E 55 AMG
The steering wheel gearshift control pro-
vides an alternative method for changing
the gears manually and limiting or extend-
ing the gear range for automatic shifting
with the gear selector lever in positionD
and driving in the automatic program
modeC orS.
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.
iFor information on using the steering
wheel gearshift control in manual pro-
gram modeM (E 55 AMG only), see
“Manual shift program” (
page 193).

!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

The transmission shifts to the next
higher gear.
If, instead of the manual program mode
symbolM, thep symbol appears in the
multifunction display (
page 184), shift to
the next higher gear. The fuel supply will
otherwise be interrupted to prevent the
engine from overrevving.
iThe manual program modeM will not
be stored. When the engine is turned
off with the manual program modeM
selected, the transmission will go to
the automatic program mode (CorS)
when the engine is restarted.
!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 24). Otherwise the engine
could be damaged which is not covered
by the Mercedes-Benz Limited
