Downshifting
Briefly press the gear selector lever to
the left in theD-direction
(page 154).
or
Press button1 on the left side of the
steering wheel (
page 162).
The transmission shifts to the next
lower gear.Upshifting

higher gear.
If, instead of the manual program mode
symbol
M, thep symbol appears in the
multifunction display (
page 153), shift to
the next higher gear. The fuel supply will
otherwise be interrupted to prevent the
engine from overrevving.
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 transmis-
sion shifts down to a gear from which
you can easily accelerate or take off.
!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
Warranty.
