or up.
i When manual drive program M is activa-
ted via the steering wheel gearshift pad-
dles, the temporarily active manual drive
program
M will be deactivated automati-
cally after a limited time, if the driving sit-
uation permits. The automatic transmis-

matic transmission automatically shifts up:
R
if the maximum engine speed on the cur-
rently engaged gear is reached and
R
you depress the accelerator pedal.
AMG vehicles:
! In manual gearshift program M, the auto-
matic transmission does not shift up auto-
matically even when the engine limiting
speed for the current gear is reached.
When the engine limiting speed is reached,
the fuel supply is cut to prevent the engine
from overrevving. You must make sure that
the engine speed does not reach the red
area of the rev counter. Otherwise, there is
a risk of engine damage.
