Roadside Assistance button 
Located below the center armrest cover is the Roadside
Assistance button. Pressing and holding the
button (for longer than 2 seconds) will initiate a call to a
Mercedes-Benz Roadside Assistance dispatcher. The
button will flash while the call is in progress. The
message “ROADSIDE ASSISTANCE – CONNECTING
CALL” will appear in the multifunction display. When
the connection is established, the message “ROADSIDE
ASSISTANCE – CALL CONNECTED” appears in the
multifunction display. The Tele Aid system will transmit
data generating the vehicle identification number,
model, color and location (subject to availability of
cellular and GPS signals).A voice connection between the Roadside Assistance
dispatcher and the occupants of the vehicle will be
established. When a voice connection is established the
audio system mutes and the message “TELE AID –
ROADSIDE ASSISTANCE CALL ACTIVE” appears in the
multifunction display. The nature of the need for
assistance can then be described. The Mercedes-Benz
Roadside assistance dispatcher will either dispatch a
qualified Mercedes-Benz technician or arrange to tow
your vehicle to the nearest Mercedes-Benz Center.
For services such as labor and/or towing charges may
apply. Refer to the Roadside Assistance manual for more
information.
These programs are only available in the USA:
•S ign an d Drive s erv ices : Ser vices such as jump start,
a few gallons of fuel or the replacement of a flat tire
with the vehicle spare tire are obtainable,
•Remote Vehicle Diagnostics: This function permits
the Mercedes-Benz Roadside Assistance dispatcher
to download malfunction codes and actual vehicle
data.
Wa r n i n g !
If you feel at any way in jeopardy when in the
vehicle (e.g. smoke or fire in the vehicle, vehicle in
a dangerous road location), please do not wait for
voice contact after you have pressed the emergency
button. Carefully leave the vehicle and move to a
safe location. The Response Center will
automatically contact local emergency officials
with the vehicle’s approximate location if they
rec eive a n a utom at ic “SO S” si gna l a nd ca nn ot ma ke
voice contact with the vehicle occupants.

cluster displayPractical hints Car care Index Important!
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 330 or jump starting on
page 332.
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 traf fic. 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.

Battery
Important!
Battery replacement information:
The maintenance-free battery is located in the engine
compartment on the right hand side.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.
Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.
Always disconnect the battery negative lead first and
connect last.
When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in starter switch position 0. The
battery, its filler caps, the vent tube and the opposite
plug must always be securely installed when the vehicle
is in operation.
While t he en gin e is run ning t he batter y te rm in al clamp s
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.
Wa r n i n g !
Failure to follow these instructions can result in
severe injury or death.Never lean over batteries while connecting, you
might get injured.Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc.

Jump startingImportant!
A discharged battery can freeze at approximately +14
°F
(–10
°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in it exploding, causing
personal injury.
Jumper cable specifications:
•Minimum cable cross-section of 25 mm
2 or
approximately 2 AWG
•Maximum length of 11.5 ft. (3.5 m).
If the battery is discharged, the engine should be started
with jumper cables and the (12 V) battery of another
vehicle.
Only use 12 V battery to jump start your vehicle. Jump
starting with more powerful battery could damage the
vehicle’s electrical systems, which will not be covered
by the Mercedes-Benz Limited Warranty.
The battery is located in the engine compartment on the
right hand side.

5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.Note:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter.
