WARNING
Electrostatic build-up can lead to the creation of sparks, which could ignit ethe highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handlin gthe battery, touc hthe vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the bat-
ter yise lectrostatically charged. Electrostatic
charge is created, for example:
R by wearing synthetic fibre clothing
R by friction betwee nclothing and the seat
R when you pull or push the battery acros scar-
pet or other synthetic materials
R when you rub the battery with acloth G
WARNING
Durin gthe charging process, abattery produ-
ces hydrogen gas. If ashor tcircuit occurs or
spark sare created, the hydrogen gas can
ignite. There is arisk of an explosion. R
Make sure that the positive terminal of a
connected battery does not com eintoc on-
tac twith vehicle parts.
R Never place metal object sortools on abat-
tery.
R It is importan tthat you observ ethe descri-
bed order of the battery terminals when
connectin gand disconnecting abattery.
R When jump-starting, make sure that the
battery poles with identical polarit yare
connected.
R It is particularly importan ttoobserv ethe
described order when connectin gand dis-
connectin gthe jump leads.
R Never connec tordisconnect the battery
terminals while the engin eisrunning. G
WARNING
Batter yacid is caustic. There is arisk of injury.
Avoid contac twith the skin ,eyes or clothing.
Do not breathe in any battery gases. Do not
lean over the battery. Keep the batteries out
of the reach of children. Immediately rinse off
battery acid thoroughly with plent yofclean
water and seek medical attention at once.

Environmental note Batteries contain pollutants.
It is illegal to dispose of them
with the household rubbish.
They must be collected sep-
arately and disposed of in anenvironmentally responsible
recycling system. Dispose of batteries in an
environmentally responsible
manner. Take discharged
batteries to
aqualified spe-
cialist workshop or to acol-
lection point for used batter-
ies.
! Have the battery checked regularly at a
qualified specialis tworkshop. 342

Booklet or contact
aqualified specialist work-
shop for more information.
! Alwaysh
ave work on the batteries carried
out at aqualified specialist workshop. Should
it, in exceptional circumstances, be abso-
lutely necessary to disconnect the 12-volt
battery yourself, please observe the follow-
ing:
R secure the vehicle to prevent it from rolling
away.
R switch the ignition off.
R first, disconnect the negative terminal, fol-
lowed by the positive terminal.
Vehicles with automatic transmission: the
transmission is locked in position Pafter dis-
connecting the battery.
After the work has been completed, firmly
reinstall the battery and the cover of the pos-
itive terminal.
Comply with safety precautions and take pro-
tective measures when handling batteries. Risk of explosion
Fire, naked flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks.
Electrolyte or battery acid is corro-
sive. Avoid contact with the skin,
eyes or clothing.
Wear suitablep rotective clothing, in
particular gloves, an apron and a
face mask.
Immediately rinse electrolyte or acid
splashes off with clean water. Con-
sult adoctor if necessary. Wear eye protection.
Keep children away.
Observe this Owner's Manual. For safety reasons, Mercedes-Benz recom-
mends that you only use batteries which have
been tested and approved for your vehicle by
Mercedes-Benz.T
hese 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 suffi-
ciently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the vehicle.In such cases, have the battery disconnected ataq ualified specialist workshop. You can also
charge the battery with acharger recommended
by Mercedes-Benz.F or more information,
please contact aqualified specialist workshop.
Have the battery charge checked more fre-
quently if you use the vehicle mainly for short
trips or if you leave it standing idle for alengthy
period. Consult aqualified specialist workshop
if you wish to leave your vehicle parked up for a
long period of time.
When you park the vehicle, remove the key if you do not require any electrical consumers. The
vehicle will then use very little energy, thus con- serving battery power. Charging the 12
Vbattery
Vehicles with alithium-ion battery:
! Only use battery chargers with
amaximum
charging voltage of 14.4 V.

WARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularlya void fire, naked flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over abattery. G
WARNING

WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not breathe in any battery gases. Do not lean over the battery. Keep the batteries out of the reach of children. Immediately rinse off battery acid
thoroughly with plenty of clean water and seek medical attention at once. G

WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs or sparks
are created, the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
If the indicator/warning lamps do not light up at low temperatures, it is very likely that the dis-
charged battery has frozen.Int his case you may neither jump-start the vehicle nor charge the
battery. The service life of abattery that has been thawed may be reduced. The starting charac-
teristics may be impaired, especially at low temperatures. Have the thawed battery checked at a
qualified specialist workshop.
