must not leak acid when upside down for at least 15
minutes. Your authorized Mercedes-Benz Center can
provide such a special battery.
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 steering lock position 0. The battery,
its filler caps, the vent tube and the opposite plug must
always be securely installed when the vehicle in operation. During removal and installation always
protect the disconnected battery positive (+) terminal
with the cover attached to the battery.
While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.
Note:
After reconnecting the battery also resynchronize the
front seat head restraints, the express feature of the
power windows, and the electronic stability program
(ESP), see pages 48, 156 and 221.
Battery recycling
Batteries contain material that can harm the
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.

Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.
2. On both vehicles:
•Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.
•Apply parking brake and shift selector lever to
position “P”.
Important!
3. Lift cover (1) and clamp one end of the first jumper
cable to the positive (+) under hood terminal (2) of
the discharged battery and the other end to the
positive (+) terminal of the charged battery. Make
sure the cable clamps do not touch any other metal
parts.

Replacing bulbsNotes:
To prevent a possible electrical short circuit, switch off
lamp prior to replacing a bulb.
When replacing bulbs, install only 12 volt bulbs with
the specified watt rating.
When replacing halogen bulbs do not touch glass
portion of bulb with bare hands. Use plain paper or a
clean cloth.
Wa r n i n g !
Bulbs and bulb holder can be very hot. Allow the
lamp to cool down before changing a bulb.
Halogen lamps contain pressurized gas. A bulb can
explode if you:
• touch or move it when hot,
•drop the bulb,
• scratch the bulb.Wear eye and hand protection.
Wa r n i n g !
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the lamp
and its components. We recommend that you have
such work done by a qualified technician.
