!
Coasting the vehicle, or driving for any
other reason with gear selector lever
inN can result in transmission damage
that is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
G
Getting out of your vehicle with the gear
selector lever not fully engaged in positionP
is dangerous. Also, positionP alone is not
intended to or capable of preventing your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (
page 57).
When parked on an incline, turn the front
wheels towards the road curb.
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could move the
gear selector lever from positionP, which
could result in an accident and/or serious
personal injury.

The current gear selector lever position
and the selected program mode (
C/S) are
indicated in the right multifunction display
(
page 165).

Press program mode selector
switch1 repeatedly until the letter of
the desired program mode appears in
the right multifunction display.
SelectCfor comfort driving:

The vehicle starts out in second
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.
!Never change the program mode when
the gear selector lever is out of
positionP. This could result in a
change of driving characteristics for
which you may not be prepared.iThe last selected program
mode (CorS) is switched on when the
engine is restarted.

iTo avoid overrevving the engine when
downshifting with steering wheel
gearshift buttons, the transmission will
not shift to a lower gear if the engine’s
max. speed would be exceeded.
!Allow engine to warm up under low
load use. Do not place full load on the
engine until the operating temperature
has been reached.
Shift into reverse gearR or parking
positionP only when the vehicle is
stopped.
Avoid spinning of a drive wheel for an
extended period when driving off on
slippery road surfaces. This may cause
serious damage to the drivetrain which
