Effect
P
Park position
Selector position when the vehicle is
parked. Only place selector lever in
positionP when vehicle is stopped.
The park position is not intended to
serve as a brake when the vehicle is
parked. Rather, the driver should al-
ways set the parking brake in addi-
tion to placing the selector lever in
positionP to secure the vehicle.
The key can only be removed from
the starter switch with the selector
lever in positionP. With the key re-
moved the selector lever is locked in
positionP.
Effect
R
Reverse gear
Place selector lever in positionR only
when vehicle is stopped.
N
Neutral
No power is transmitted from the en-
gine to the drive axle. When the
brakes are released, the vehicle can
be moved freely (pushed or towed).
To avoid damage to the transmission,
never engageN while driving.
If ESP is deactivated or malfunction-
ing:
Only move selector lever toN if the
vehicle is in danger of skidding (e.g.
on icy roads).
D
Drive
The transmission shifts automatical-
ly. All five forward gears are avail-
able.
!Coasting the vehicle, or driving for any
other reason with 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 selector
lever not fully engaged in positionP is dan-
gerous. Also, positionP alone is not intend-
ed to or capable of preventing your vehicle
from moving, possibly hitting people or ob-
jects.
Always set the parking brake in addition to
shifting to positionP (
page 51).
When parked on an incline, turn the front
wheels towards the road curb.

S Standard For regular driving
W Winter For winter driving

Press the program mode selector
switch repeatedly until the letter of the
desired shift program appears in the
multifunction display (
page 107).
Select
Wfor winter 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 im-
proved 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.


The power transmission ratio for se-
lector lever positionR changes de-
pending on the program mode
selected (
W or
S).
Warning!
G
When leaving the vehicle, always remove the
key from the starter switch, and lock the ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Children could move the selector le-
ver from positionP, which could result in an
accident and/or serious personal injury.
!Never change the program mode when
the selector lever is out of positionP. It
could result in a change of driving char-
acteristics for which you may not be
prepared.
