cluster displayPractical hints Car care Index
Tele Aid system could not initiate an Information call
(e.g. the relevant cellular phone network is not
available). The message “INFO – CALL FAILED” appears
in the multifunction display.
Information calls can be terminated using the
ìbutton on the multifunction steering wheel.
Important!
If the indicator lamps do not start flashing after
pressing one of the buttons or remain illuminated (in
red) at any time, the Tele Aid system has detected a fault
or the service is not currently active, and may not
initiate a call. Visit your Mercedes-Benz Center and
have the system checked or contact the Response Center
at 1-800-756-9018 (in the USA) or 1-888-923-8367 (in
Canada) as soon as possible.Upgrade Signals
Tele Aid system processes calls using the following
priority.
•Automatic emergency – First priority
•Manual emergency – Second priority
•Roadside assistance – Third priority
•Information – Fourth priority
Should a higher priority call be initiated while you are
connected, an upgrade (alternating) tone will be heard,
and the appropriate indicator lamp will flash. If certain
information such as vehicle identification number or
client information is not available, the operator may
need to retransmit. During this time you will hear a
chirp and voice contact will be interrupted. Voice
contact will resume once the retransmission is
completed. Once a call is concluded, a chirp will be
heard and the appropriate indicator lamp will stop
flashing. The COMAND system operation will resume
(only vehicles with COMAND).

cluster displayPractical hints Car care Index Automatic transmissionThe 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 vehicle or before working on the
vehicle with the engine running, firmly depress the
parking brake pedal 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.
Accelerator position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full
throttle) = downshifting to a lower gear = maximum
acceleration. Once the desired speed is attained, ease up
on the accelerator – the transmission shifts up again.
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.

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 200 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 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 gear selector lever from
position “P”, which could result in an accident or
serious personal injury.

Selector lever position
The current selector lever position is indicated in the
gear range indicator display. The automatic gear
shifting process can be adapted to specific operating
conditions using the selector lever.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
steering lock with the selector lever in
position “P”. With the electronic key removed, the
selector lever is locked in position “P”.
With a malfunction in the vehicle’s electrical
system the selector lever could remain locked in
position “P”. To unlock the selector lever
manually, see page 272.

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 winter driving instructions on
page 207).
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.Gear selection for special circumstances
The transmission gear ranges for special circumstances
can be selected by pressing the selector lever to the
right or the left with the selector lever in position “D”.
The gear range currently selected is indicated in the
instrument cluster display.
Briefly press selector lever in the çdirection:
The transmission downshifts, one gear at a time, in the
order “4”, “3”, “2”, “1”.
Press and hold selector lever in the çdirection:
The selector lever position display will switch to the
gear range currently selected by the automatic
transmission.
The transmission will only shift down one gear if the
gear range currently selected has already shifted to its
highest possible gear.
Briefly press selector lever in the ædirection:
The transmission will shift from the current gear range
to the next higher gear range. If the transmission is
already in gear range “D”, an additional upshift of one
gear is possible.

Press and hold selector lever in the ædirection:
The transmission will shift from the current gear
directly to gear range “D”.
Important!
With transmission in gear range “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
quickly 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 gear range, the transmission will not
shift to a lower gear, if the engine’s revolutions per
minute limit would be exceeded. In this case there will
be no downshift, even when the vehicle speed reaches
the engine’s RPM limit of that gear, e.g. by applying the
service brakes.
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.
