gear (both forward and reverse) for
gentler starts. This does not apply if
full throttle is applied or gear
range1 is selected.


Traction and driving stability are
improved on icy roads.


Upshifts occur earlier even when
you give more gas. The engine then
operates at lower rpms and the
wheels are less likely to spin.
SelectSfor sporty driving:


The vehicle starts out in first gear.


Upshifts occur later.Manual shift program
In the manual program mode M,
system-controlled automatic gearshifting
is switched off and you need to change the

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 button1
(page 194).
The transmission shifts to the next
lower gear.
i
The manual program modeM will not be
stored. When the engine is turned off with the
manual program modeM selected, the transmis-
sion will go to the automatic program mode
(CorS) when the engine is restarted.
!
In the manual program modeM, the trans-
mission will not upshift, even if the engine has
reached its overrewing range. Shift up to the
next gear before the engine has reached its over-
rewing range. Make absolutely certain that the
engine speed does not reach the red marking on
the tachometer (
page 28). Otherwise the en-
gine 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.

Warning!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.i
Severe conditions (e.g. strong air pollution)
may require replacement of the filter before its
scheduled interval. A clogged filter will reduce
the air volume to the interior.
If the vehicle interior is hot, ventilate the interior
before driving off, see “Summer opening fea-
ture” (page 239). The automatic climate con-
trol will then adjust the interior temperature to
the set value much faster.
Keep the air intake grille in front of the wind-
shield free of snow and debris.
Warning!
G
When the automatic climate control system
is switched off, the outside air supply and
circulation are also switched off. Only
choose this settings for a short time. Other-
wise the windows could fog up, impairing
visibility and endangering you and others.
