cluster displayPractical hints Car care Index The first 1 000 miles (1 500 km)
The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.
During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.
Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).
After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.Maintenance
Approximately 30 days or 2000 miles (2000 km) prior to
the next recommended service, the remaining distance
or days are displayed in the main odometer field. See
Flexible service system on page 80.
We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Center, in
accordance with the Service Booklet at the times called
for by the FSS.
Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times/
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.

cluster displayPractical hints Car care Index Starting and turning off the engine
Before starting
Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”. Turn key in steering lock
to position 2.
Starting
Do not depress accelerator. Briefly turn key in steering
lock 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 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 nonrepeat feature, the 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.
Turning off
Turn the key in the steering lock to position 0 to stop the
engine.
Vehicles with automatic transmission:
The key can only be removed with your foot off the
brake pedal and the selector lever in position “P”.

168 Automatic transmission
Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index
Automatic transmission
The automatic transmission selects individual gears
automatically, dependent upon
•Selector lever position
• Program mode selector
• Accelerator position
• Vehicle speed
The gear shifting process is continuously adapted,
dependent on the driving style, the driving situation
and the road characteristics.
Important!
When parking the car or before working on the vehicle
with the engine running, firmly engage the parking
brake and shift the selector lever into “P”.
Driving
The selector lever is automatically locked while in
position “P”. To move the selector lever out of position
“P”, the service brake pedal must be firmly depressed
before the shift lock will release.Shift selector lever to the desired position only when the
engine is idling normally and the service brake is
applied. Do not release the brake until ready to drive.
The vehicle may otherwise start creeping when the
selector lever is in drive or reverse position.
Important!
After selecting any driving position from “N” or “P”,
wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.
Wa r n i n g !
It is dangerous to shift the selector lever out of “P”
or “N” 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 in
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.

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 key can be removed from the steering lock
only with the foot off the brake pedal and the
selector lever in position “P”. With the key
removed, the selector lever is locked in
position “P”.
Reverse gear
Shift to reverse gear only with the vehicle
sto pp ed.
Depending 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 182).
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.
Upshift through 4th gear only. Suitable for
performance driving. To shift from position “D”
to “4”, push selector lever to the left.
Upshift through 3rd gear only. Suitable for
moderately steep hills. Since the transmission
does not shift higher than 3rd gear, this gear
selection will allow use of the engine’s braking
power downhill.

171 Automatic transmission
Te ch n ica l
data Instruments
and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Upshift through 2nd gear only. For driving in
mountainous regions or under extreme operating
conditions. This gear selection will allow use of
the engine’s braking power when descending
steep grades.
Use this position, which makes maximum use of
the engine’s braking effect, while descending
very steep or lengthy downgrades and only at
speeds below 40 mph (60 km/h).
Important!
With selector lever in position “D”, “4” or “3”, upshifting
from 1st to 2nd to 3rd gear is delayed depending on
vehicle speed and engine temperature. This allows the
catalytic converter to heat up more q uickly to operating
temperatures.
During the brief warm-up period this delayed upshift
and increased engine noise might be perceived as a
malfunction. However, neither the engine nor
transmission are negatively affected by this mode of
operation.
The delayed upshift is effective with vehicle speeds
below 31 mph (50 km/h) at partial throttle and engine
temperatures below 95°F (35°C).To avoid overrevving the engine when the selector lever
is moved to a lower driving range, the transmission will
not shift to a lower gear, if the engine’s speed limit
would be exceeded. In this case there will be no
downshift, even when the vehicle speed reaches the
engine’s speed limit of that gear, e.g. by applying the
service brakes. Continue driving in the usual manner.
The transmission will then shift down automatically.
To prevent the engine from laboring at low RPM when
driving uphill gradients or with your vehicle heavily
loaded, the automatic transmission will downshift when
necessary to maintain engine RPM within the best
torque range.
Wa r n i n 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.

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
only slight partial throttle.
Rocking a vehicle free in this manner may cause the
ABS malfunction indicator lamp to come on. Turn off
and restart the engine to clear the malfunction
indication.
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.
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”.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.
