0The electronic key can be withdrawn in this position
only. The steering is locked when the electronic key
is removed from the starter switch. If necessary,
move steering wheel slightly to allow the locking
mechanism to engage.
In vehicles with automatic transmission, the
electronic key can be removed only with the selector
lever in position “P”. After removing the electronic key or with the electronic key in starter switch
position 0 or 1 the selector lever is locked in
position “P”.
1Most electrical consumers can be operated. For
detailed information see respective subjects.

Gear selector lever is unlocked.
To move the selector lever out of position “P” firmly
depress the service brake pedal.

When leaving the vehicle always remove the
electronic key from the starter switch, and lock the
vehicle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehicle.
Unsupervised use of vehicle equipment may cause
serious personal injury.

If the electronic key is left in the starter switch
position 0 for a extended period of time, it can no longer
be turned in the lock. In this case, remove electronic key
from starter switch and reinsert.
Caution!
To prevent accelerated battery discharge and a possible
dead battery, always remove the electronic key from the
starter switch. Do not leave the electronic key in starter
switch position 0.Notes:
A warning sounds when the driver’s door is opened
with the electronic key is in starter switch position 1
or 0.
If the electronic key cannot be turned in the starter
switch, the vehicle battery may not be sufficiently
charged. See battery on page 336 or jump starting on
page 338.
With the engine at idle speed, the charging rate of the
alternator (output) is limited.
It is therefore recommended that you turn off
unnecessary electrical consumers while driving in stop-
and-go traffic. This precaution helps to avoid draining of
the battery.
Unnecessary strain on the battery and charging system
may be minimized by turning off the following power
consumers, for example:
Heated seats, rear window defroster. In addition, the
automatic climate air volume control should be set to
the lowest position.

Due to the installed starter non-repeat feature, the
electronic key must be turned completely to the left
before attempting to start the engine again.
In areas where temperatures frequently drop below -4
°F
(-20
°C) we recommend that an engine block heater be
installed. Your authorized Mercedes-Benz Center will
advise you on this subject, see page 265.Turning off
Turn the electronic key in the starter switch to
position 0 to stop the engine.
Vehicles with automatic transmission:
The electronic key can only be removed with the
selector lever in position “P”.

Manual transmission
See illustration for gearshift lever positions
corresponding to the individual gears.Stop the vehicle completely before shifting into reverse;
to shift into reverse, pull the gearshift lever up.
Do not exceed the maximum engine speed in the
individual gears. Refer to tachometer (see page 101) for
engine speeds.
Important!
Downshifting gears leading to overrevving the engine
can result in transmission damage that is not covered
by the Mercedes-Benz Limited Warranty.
Do not exceed engine speed limits, see page 101.

Wa r n i n g !
For vehicles equipped with a manual transmission,
getting out of your vehicle with the gearshift lever
not engaged in 1st or reverse gear and parking
brake engaged is dangerous.
Also, when parked on an incline, an engaged 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, see page 256 for
parking brake. When parked on an incline, also turn front wheel
towards the road curb.When leaving the vehicle always remove the key
from the steering lock, 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 or serious injury.
Wa r n i n g !
On slippery road surfaces as well as high engine
speeds, 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.

Stopping
For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.
When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.
Maneuvering
To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.
To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
slight partial throttle.Rocking a vehicle free in this manner may cause the
ABS or traction system malfunction indicator lamp to
come on. Turn off and restart the engine to clear the
malfunction indication.
Wa r n i n g !
Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, when parked on an incline, position “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.Always set the parking brake in addition to shifting
to position “P”, see page 256 for parking brake. When parked on an incline, also turn front wheel
towards the road curb.When leaving the vehicle always remove the key
from the steering lock, and lock the vehicle. Do not
leave children unattended in the vehicle, or with
access to an unlocked vehicle. Children could move
the selector lever from position“P”, which could
result in an accident or serious injury.

Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Note:
The electronic key can only be removed from the
starter switch with the selector lever in
position “P”. With the electronic key removed, the
selector lever is locked in position “P”.
Reverse gear
Shift to reverse gear only with the vehicle
stopped.
Dependent on the program mode selector switch
position “S” or “W” the maximum speed in the
reverse gear is different. However, it is not
possible to change the program mode while in
reverse.Neutral
No power is transmitted from the engine to the
drive axle. When the brakes are released, the
vehicle can be moved freely (pushed or towed). Do
not engage “N” while driving except to coast
when the vehicle is in danger of skidding (e.g. on
icy roads, see page 264 for winter driving
instructions).
Important!
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.
The transmission automatically upshifts through
5th gear. Position “D” provides optimum driving
characteristics under all normal operating
conditions.
