(Electronic Stability Program). The operating
safety of your vehicl emay be restricted. You

In the event of
ashort circuit or asimilar inci-
dent, contact aqualifieds pecialist workshop
immediately.Don ot drive any further. You
shouldh ave all work involving the battery car-
ried out at aqualifieds pecialist workshop. G
WARNING
Electrostatic build-up can leadtot he creation
of sparks, which could ignite the highlye xplo-
sive gases of abattery. There is arisk of an
explosion.
Before handling the battery, touch the vehicle body to remove any existing electrostatic
build-up.
The highlyf lammable gas mixture forms when
charging the battery as wellasw hen jump-
starting.
Alwaysm ake sure that neither you nor the
battery is electrostatically charged. Abuild-
up of electrostatic charge can be caused, for
example:
R by wearing clothing made from synthetic
fibers
R due to friction betwee nclothing and seats
R if you push or pullt he battery across the
carpet or other synthetic materials
R if you wipet he battery with acloth G
WARNING
During the charging process, abattery produ-
ces 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 a
connected battery does not come into con- tact with vehicle parts.
R Never place metal objects or tools on abat-
tery.
R It is important that you observe the descri-
bed order of the battery terminals when
connecting and disconnecting abattery.
R When jump-starting, make sure that the
battery polesw ith identical polarity are
connected. R
It is particularly important to observe the
describe dorder when connecting and dis-
connecting the jumper cables.
R Never connect or disconnect the battery
terminals whilet he engine is running. G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing.
Do not inhalea ny battery gases.Don ot lean

Environmental 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 to
aqualifieds pe-
cialist workshop or aspecial
collection point for used bat- teries.
! Have the battery checked regularly at a
qualified specialist workshop.
Observe the service intervals in the Main-
tenance Booklet or contact aqualified spe-
cialist workshop for more information.
! You shouldh
ave all work involving the
battery carried out at aqualified specialist
workshop. In the exceptional case that it is
necessary for you to disconnect the battery yourself, make sure that:
R you switch off the engine and remove the
SmartKey. On vehicle swith KEYLESS-
GO, ensure that the ignition is switched
off. Check that all the indicator lampsin

electronic components, such as the
alternator, may be damaged.
R you first remove the negativ eterminal
clamp and then the positive terminal
clamp. Never swap the terminal clamps.
Otherwise, the vehicle's electronic sys-
tem may be damaged.
R the transmission is locked in position P
after disconnectingt he battery. The vehi-
cle is secured against rolling away. You
can then no longer move the vehicle.
The batter yand the cover of the positive
terminal clamp must be installed securely
during operation.
Comply with safety precaution sand take pro-
tective measures when handling batteries. Risk of explosion.
Fire, open flames and smoking are
prohibited when handling the bat-
tery. Avoid creating sparks. Battery acid is caustic
.Avoid con-
tact with skin ,eyes or clothing.
Wear suitable protective clothing,
especially gloves, apron and face-
guard.
Rinse any acid spills immediately
with clear water. Contac taphysi-
cian if necessary. Wear eye protection.
Keep children away.
Observe this Operator's Manual.
For safety reasons, Mercedes-Benzr ecom-
mends that you only use batteries which have been tested and approved for your vehicle by
Mercedes-Benz. These batteries provide increased impact protection to preven
tvehi-
cle occupants from sufferin gacid burns
should the batter ybedamaged in the event of
an accident.
In order for the batter ytoachieve the maxi-
mum possible servic elife, it must alway sbe
sufficiently charged.
The vehicle battery, like other batteries, can
discharge over time if you do not use the
vehicle. In this case, have the batter ydiscon-
nected at aqualified specialist workshop. You
can also charge the batter ywithacharger
recommended by Mercedes-Benz. Contac ta
qualified specialist worksho pfor further infor-
mation.
Have the batter ycondition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standing idle
for alengthy period. Consult aqualified spe-
cialist worksho pifyou wish to leave your
vehicle parked for along period of time.
i Remove the SmartKey if you park the
vehicle and do not require any electrical
consumers. The vehicle will then use very
little energy, thus conservin gbattery
power.
i If the batter
ypower supply has been inter-
rupted, e.g. if the batter ywas fully dis-
charged, you will need to reset the "exterior
mirror sautomatic folding function", by
