charging the battery as well as whenjump-
starting.
Always makesure that neither you northe
battery is electrostatically charged.Abuild-
up of electrostaticcharge can be caused, for
example:
Rby wearing clothing made from synthetic
fibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the
carpet or other synthetic materials
Rif you wipe the battery withacloth
GWARNING
During the charging process,abattery
produces hydrogen gas. Ifashort circuit
occurs or sparks are created, the hydrogen
gas can ignite. There isarisk of an explosion.
RMake sure that the positive terminal of a

HEnvironmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries toaqualified
specialist workshop or a
special collection point for
used batteries.
!Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the
MaintenanceBooklet or contactaqualified
specialist workshop for more information.

battery carried out ataqualified specialist
workshop. In theexceptional casethatitis
necessaryfor you to disconnect thebattery
yourself, makesure that:
Ryou switch off theengineand remove the
SmartKey. On vehicles withKEYLESS-
GO, ensure that theignition is switched
off.Check that all the indicator lamps in
the instrumentcluster are off.Otherwise,
electroniccomponents, such as the
alternator,may be damaged.
Ryou first remove the negative terminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic
system may be damaged.
Rthe transmission is locked in positionP
after disconnectingthe battery. The

The battery and the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precautions and take
protective measures when handling
batteries.
Risk of explosion.
Fire, open flames and smokingare
prohibited when handling the
battery. Avoid creatingsparks.
Battery acid is caustic. Avoid
contact with skin, eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and
faceguard.
Rinse any acid spills immediately
with clear water. Contact a
physician if necessary.
Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benz
recommends that you only use batteries
which have been tested and approved for
your vehicle by Mercedes-Benz.These
batteries provide increased impact
protection to prevent vehicle occupants from
suffering acid burns should the battery be
damaged in the event of an accident.
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the battery
disconnected ataqualified specialist
workshop. You can also charge the battery
withacharger recommended by Mercedes-
Benz.Contactaqualified specialist workshop
for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standingidle
foralengthy period. Consultaqualified
specialist workshop if you wish to leave your
vehicle parked foralong period of time.
iRemove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conserving battery
power.
iIf the power supply has been interrupted,
e.g. if you reconnect the battery, you will
have to:
Rset the clock.Information on setting the
clock can be found in the separate
operating instructions.
On vehicles with COMAND and a
navigation system, the clock is set
automatically.
Rreset the function for folding the exterior
mirrors in/out automatically, by folding
the mirrors out once (Ypage 110).

There isarisk of an explosion.
Allow the frozen battery to thaw out before
charging it or jump-starting.
!Only use battery chargers with a
maximum charging voltage of 14.8 V.
!Only charge the battery using the jump-
startingconnection point.
The jump-starting connection point is in the
engine compartment(Ypage 326).
XOpen the hood (Ypage 306).
XConnect the battery charger to the positive
terminal and ground point in the same
order as when connecting the donor
battery in the jump-starting procedure
(Ypage 326).
If, at low temperatures, the indicator lamps/
warning lamps in the instrumentcluster do
not light up, it is highly likely that the
discharged battery has frozen.Inthis case,
you may neither charge the battery nor jump-
start the vehicle. The service life ofathawed-
out battery may be shorter. The starting
characteristics may be impaired, especiallyat
low temperatures. Have the thawed-out
battery checked ataqualified specialist
