Warning!
G
A driver’s attention to the road must always
be his/her primary focus when driving. For
your safety and the safety of others, we rec-
o m m e n d t h a t y o u p u l l o v e r t o a s a f e l o c a t i o n
and stop before placing or taking a tele-
phone call. If you choose to use the tele-
phone while driving, please use the
hands-free device and only use the tele-
phone when weather, road and traffic condi-
tions permit.
Some jurisdictions prohibit the driver from
using a cellular telephone while driving a ve-
hicle.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.

130 Controls in detailManual transmission
Manual transmissionInformation for driving with a manual
transmission is found in the “Getting start-
ed” section (
page 41).
Gearshift leverDo not exceed the maximum speed in the
individual gears. Refer to tachometer
(page 22) for engine speeds.
Warning!
G
For vehicles equipped with a manual trans-
mission, getting out of your vehicle with the
gearshift lever not engaged in 1st or reverse
gear and parking brake engaged is danger-
ous. Also, when parked on an incline, an en-
gaged 1st 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 1st or reverse gear (
page 51).
When parked on an incline, turn the front
wheel towards the road curb.
Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.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 gearshift
lever, which could result in an accident
and/or serious injury.

Controls in detail
Automatic transmission*
Gear selector lever position
Effect
P
Park position

Selector position when the vehicle is
parked. Only place selector lever in
position P 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
position P to secure the vehicle.
The key can only be removed from
the starter switch with the selector
lever in position P. With the key re-
moved the selector lever is locked in
position P.
R
Reverse gear
Place selector lever in position R only
when vehicle is stopped.
Effect
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 engage N while driving.
If ESP is deactivated or malfunction-
ing:
Only move selector lever to N 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 in N
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 position P is dan-
gerous. Also, position P 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 position P (
page 51).
When parked on an incline, turn the front
wheels towards the road curb.

gentler starts. This does not apply if
full throttle is applied or gear
range 1 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 position R 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 position P, which could result in an
accident and/or serious personal injury.
!Never change the program mode when
the selector lever is out of position P. It
could result in a change of driving char-
acteristics for which you may not be
prepared.
