Upshifting
̈ Briefly press right shift button 2
(
page 207).
The transmission shifts to the next
higher gear.
If you have selected the AMG menu in the
control system (
page 168) and you are
driving in the manual program mode M,
upshift indicator 2 in the multifunction
display advises you to upshift before the
engine reaches the overspeed range. Thus
you can drive at the maximum engine
speed for each gear without overrevving
the engine.
1 Gear indicator
2 Upshift indicator
̈ Shift to the next higher gear.
The fuel supply will otherwise be inter-
rupted to prevent the engine from over-
revving.
Downshifting
̈ Briefly press left shift button 1
(
page 207).
The transmission shifts to the next
lower gear.
!
In the manual program mode M, the trans-
mission will not upshift, even if the engine has
reached its overrevving range. Shift up to the
next gear before the engine has reached its over-
revving range. Make absolutely certain that the
engine speed does not reach the red marking on
the tachometer (
page 157). Otherwise the
engine could be damaged which is not covered
by the Mercedes-Benz Limited Warranty.
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.
i
When you brake or stop, the transmission
shifts down to a gear from which you can easily
accelerate or drive off.
