Manual drive program
In manual drive program M, you need to
change gearyourself using the steering wheel
gearshift paddles (Y page 228). At low engine
speeds, the transmission shifts down auto-
matically.
!
In manual drive program M, the transmis-
sion does not shift up automatically even
when the engine limiting speed for the cur-
rent gear is reached. When the engine lim-
iting speed is reached, the fuel supply is cut
to prevent the engine from overrevving.
Always make sure that the engine speed
does not reach the red area of the rev coun-
ter and observe the upshift indicator. There
is otherwise a risk of engine damage.

Upshift indicator
The upshift indicator is a four-stage display
designed to assist you in sporty driving.
The upshift indicator allows you to recognise
the ideal shift point for dynamic acceleration.
White segments : and yellow segment ;
light up in succession from left to right.
When red segments = light up and the "up"
message appears in the multifunction dis-
play, the ideal shift point has been reached:
X
Shift up using the right-hand steering wheel
gearshift paddle (UP) as quickly as possi-
ble.
The vehicle shifts up to the next gear.
i
If you continue to increase the engine
speed without shifting up in time, the fuel
supply is shut off to protectthe engine. This
results in abruptly reduced acceleration.
Instrument cluster

Risk of accident
No further messages can be displayed if the
instrument cluster or the multifunction dis-
play fails.
This means that you will not see information
about the driving situation, such as the speed,
outside temperature, warning/indicator
lamps, display messages or system failures.
The vehicle's handling characteristics may be
affected. Adapt your driving style and speed
accordingly.
Immediately consult a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required. Mercedes-Benzrecommends that
you use a Mercedes-Benz Service Centre for
this purpose. In particular, work relevant to
safety or on safety-related systems must be
carried out at a qualified specialist workshop.
Engine oil temperature display
The engine oil temperature gauge is in the
instrument cluster on the right-hand side.
Under normal operating conditions, the tem-
perature may rise to 140 † .
