Getting out of your vehicle with the gear se-
lector lever* not fully engaged in positionP
(manual transmission: first or reverse gear)
is dangerous. Also, when parked on an in-
cline, positionP (manual transmission: first

or objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, also turn the
front wheels towards the road curb.

move the gear selector lever* from
positionP (manual transmission: into
Neutral), either of which could result in an
accident and/or serious personal injury.

Manual transmission
Manual transmission is standard equip-
ment on select models and not available
on all models.
For information on driving with a manual
transmission, see “Driving off”
(
page 53).
Warning!G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in first or
reverse gear and the parking brake not
engaged is dangerous.
Also, when parked on an incline, an engaged
first or reverse gear alone may not prevent
your vehicle from moving, possibly hitting
people or objects.
Always set the parking brake in addition to
engaging first or reverse gear (
page 59).
W h e n p a r k e d o n a n i n c line, turn front wheels
towards the road curb.
Do not park this vehicle in areas where com-
bustible 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 from the starter switch, take it
with you, and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could move the gearshift lever, which could
result in an accident and/or serious
personal injury.
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.

cover of the shifting gate showing the
current gear selector lever position.
The indicators come on when you insert
the SmartKey into the starter switch, and
go out when you remove the SmartKey
from the starter switch.
Shifting procedure
The automatic transmission selects indi-
vidual gears automatically, depending on:
gear selector lever positionD
(
page 157) with gear ranges
(
page 160)
the selected program mode:
(C/S)(
page 161)
or
(M/C/S)* (
page 165)
the position of the accelerator pedal
(
page 159)
the vehicle speedWhen the gear selector lever is in drive
positionD, you can influence transmission
shifting by:
limiting the gear range
changing gears manually
Warning!G
It is dangerous to shift the gear selector
lever out of park positionP or neutral
positionN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.
!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 park 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 is not covered by the
Mercedes-Benz Limited Warranty.
