Before Starting
Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”.
Starting
Important!
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 251.
Starting the engine with electronic key:
Do not depress accelerator.
Turn electronic key in starter switch to position 2.
Briefly turn electronic key in starter switch clockwise to
the stop and release. The starter will engage until the
engine is running.
If engine will not run, and the starting procedure stops,
turn electronic key completely to the left and repeat
starting the engine.After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz
Center.
Important!
Due to the installed starter non-repeat feature, the
electronic key must be turned completely to the left

and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index 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 242 for parking brake. When parked on an incline, also turn front wheel
against curb.Wa r n i n g !
When leaving the vehicle always remove the
electronic key from the starter switch, take the
KEYLESS-GO-card (if so equipped) 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 gear selector lever
from position “P”, which could result in an
accident or serious injury.

Press switch on symbol “W”. The vehicle starts
out in 2nd gear, except with selector lever in 1st
gear, or with accelerator pedal in kick-down
position.
The “W” mode helps to improve traction and
driving stability of the vehicle.
The gear shifting process occurs at lower vehicle
and engine speeds than in the “S” program mode.
Caution!
Never change the program mode when the selector lever
is out of position “P”. It could result in a change of
driving characteristics for which you may not be
prepared.
Important!
Always be certain of the program mode selected since
the vehicle driving characteristics change with the
selection of the program mode.
Dependent on the program mode selector switch
position “S” or “W” and the gear selector lever in
position “R”, the ratio of power transmission changes.Emergency operation
(Limp home mode)
If vehicle acceleration worsens or the transmission no
longer shifts, the transmission is most likely operating
in Limp Home Mode which engages when there is a
malfunction of the transmission. This condition may be
accompanied by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster coming on.
In this mode only the 2nd gear or reverse gear can be
activated.
To engage 2nd gear or reverse:
1. Sto p t h e v e h i c l e .
2. Move selector lever to position “P”.
3. Turn off the engine.
4. Wait approximately 10 seconds.
5. Restart the engine.
6. Move selector lever to position “D” (for 2nd gear), or
move selector lever to position “R” (for reverse gear).
Have the transmission checked at your authorized
Mercedes-Benz Center as soon as possible.

Power assistance
BrakesThe condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.
If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake fluid
level in the reservoir is too low.
Brake pad wear or a leak in the system may be the
reason for low brake f luid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
After driving in heavy rain for some time without
applying the brakes or through water deep enough
to wet brake components, the first braking action
may be somewhat reduced and increased pedal
pressure may be necessary to obtain expected
braking effect. Be sure to maintain a safe distance
from vehicles in front.Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.
Wa r n i n g !
If other than recommended brake pads are
installed, or other than recommended brake fluid
is used, the braking properties of the vehicle can be
degraded to an extent that safe braking is
substantially impaired. This could result in an
accident.

247 Driving instructions
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Tires
Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately
1/16 in (1.5 mm), at which point the tire is
considered worn and should be replaced.
The tread wear indicator appears as a solid band across
the tread.
Wa r n i n g !
If you feel a sudden significant vibration or ride
disturbance, or you suspect that possible damage to
your vehicle has occurred, you should turn on the
hazard warning f lashers, carefully slow down, and
drive with caution to an area which is a safe
distance from the roadway.Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Center or
tire dealer for repairs.
Wa r n i n g !
Do not allow your tires to wear down too far. As
tread depth approaches
1/16 in (1.5 mm), the
adhesion properties on a wet road are sharply
reduced.
Depending upon the weather and / or road surface
(conditions), the tire traction varies widely.

3Canceling
To cancel the cruise control, briefly push lever to
position 3.
When you step on the brake pedal or the vehicle
speed drops below approximately 25 mph (40 km /
h), for example when driving upgrade, the cruise
control will be canceled.
If the cruise control cancels by itself and remains
inoperative until the engine is restarted, have the
system checked at your authorized Mercedes-Benz
Center as soon as possible.4Resume
If the lever is briefly pushed to position 4 when
driving at a speed exceeding approximately 25 mph
(40 km / h), the vehicle resumes the speed which
was set prior to the cancellation of the cruise
control.
The selected speed is shown for approximately
5 seconds in the multifunction display, and the
corresponding speedometer segments from the
selected speed to the vehicle maximum speed are
illuminated.
The last memorized speed is canceled when the
electronic key in the starter switch is turned to
position 1 or 0.
Important!
Moving gear selector lever to position “N” switches the
cruise control off.
