shift to the next higher gear. The fuel
supply will otherwise be interrupted to
prevent the engine from overrevving.
iThe MANUAL program mode will not
be stored. When the engine is turned
off with the MANUAL program mode
selected, the transmission will go to
the automatic program mode (CorS)
when the engine is restarted.
!In the MANUAL program mode, 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.

(Limp Home Mode)
If vehicle acceleration worsens or the
transmission no longer shifts, the trans-
mission is most likely operating in limp
home (emergency operation) mode. In this
mode only second gear and reverse gear
can be activated.
Stop the vehicle in a safe location.

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.
