Battery (vehicle)
Important safety notes
Special tools and expert knowledge are required
when working on the battery, e.g. removal and
installation .You should therefore have all work
involvin gthe battery carried out at aqualified
specialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to ashort circuit and
thus damage the vehicle electronics. This can
lead to function restriction sapplying to
safety-relevant systems, e.g the lighting sys-
tem, the ABS (anti-loc kbraking system) or the
ESP
®(Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
Rwhen braking
Rin the event of abrupt steerin gmaneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is arisk of an accident.
In the event of ashort circuit or asimilar inci-
dent, contact aqualified specialist workshop
immediately. Do not drive any further .You
should have all work involvin gthe battery car-
ried out at aqualified specialist workshop.
For further information about ABS and ESP
®,
see (Ypage 55) and (Ypage 58).
GWARNING
Electrostatic build-up can lead to the creation of sparks, which could ignite the highly explo-
sive gases of abattery. There is arisk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existin gelectrostatic
build-up.
The highly flammable gas mixture forms when
charging the battery as well as when jump-start-
ing.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Abuild-up of
electrostatic charge can be caused, for exam-
ple:
Rby wearing clothin gmade from synthetic
fibers
Rdue to friction between clothin gand seats
Rif you push or pull the battery across the car-
pet or other synthetic materials
Rif you wipe the battery with acloth
GWARNING
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.
RMake sure that the positive terminal of a
connected battery does not come into con-
tact with vehicle parts.
RNever place metal object sortools on abat-
tery.
RIt is importan tthat you observe the descri-
bed order of the battery terminals when
connectin gand disconnectin gabattery.
RWhen jump-starting, make sure that the
battery poles with identical polarity are
connected.
RIt is particularly importan ttoobserve the
described order when connectin gand dis-
connectin gthe jumper cables.
RNever connect or disconnect the battery
terminals while the engine is running.
GWARNING
Battery acid is caustic. There is arisk of injury.

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point in the engine com-
partment,consisting of apositive terminal and aground point.
GWARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with skin, eyes or clothing. Do not inhale any battery gases. Do not lean over the
battery. Keep children away from batteries. Wash away battery acid immediately with plenty of
clean water and seek medical attention.
GWARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient ven-
tilation while charging and jump-starting. Do not lean over abattery.
GWARNING
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.
RMake sure that the positive terminal of aconnected battery does not come into contact with
vehicle parts.
RNever place metal objects or tools on abattery.
RIt is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
RWhen jump-starting, make sure that the battery poles with identical polarity are connected.
RIt is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
RNever connect or disconnectt he battery terminals while the engine is running.
GWARNING
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.
!Avoid repeated and lengthy starting attempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
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 charge the battery nor jump-start the
vehicle. The service life of athawed-out battery may be shorter. The starting characteristicsc an be
impaired, particularly at low temperatures. Have the thawed-out battery checked at aqualified
specialist workshop.

not be towed with the rear axle raised. The
vehicle/trailer combination may otherwise
swerve or even roll over.
Transporting the vehicle

Fuses
Important safety notes
GWARNING
If you manipulate or bridge afaulty fuse or if
you replace it with afuse with ahigher amper-
age, the electric cables could be overloaded.
This could result in afire. There is arisk of an
accident and injury.
Alwaysr eplace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of the
same rating, which you can recognize by the
color and value.T he fuse ratings are listed in the
fuse allocation chart.
The fuse allocation chart is located in the vehicle
tool kit in the stowage compartment under the
trunk floor (
Ypage 241).
If an ewly inserted fuse also blows, have the
cause traced and rectified at aqualified special-
ist workshop, e.g. an authorized Mercedes-Benz
Center.
!Only use fuses that have been approved for
Mercedes-Benz vehicles and which have the
correct fuse rating for the system concerned.
Otherwise, componentsors ystems could be
damaged.
!Make sure that no moisture can enter the
fuse box when the cover is open.
!When closing the cover, make sure that it is
lying correctly on the fuse box. Moisture seep-
ing in or dirt could otherwise impair the oper-
ation of the fuses.
The fuses in your vehicle serve to close down
faulty circuits. If afuse blows, all the compo-
nentsont he circuit and their functions stop
operating.
