increased impact protection to prevent vehicle
occupants from suffering aci dburns shoul dthe
battery be damaged in the event of an accident.
In order for the battery to achieve the maximum
possibl eservice life, it must always be suffi-
ciently charged.
Like othe rbatteries, the vehicl ebattery may
discharge ove rtime if yo udonot usethe vehicle.
In thisc ase, have the battery disconnected at a

The vehicle will then use very little energy, thus
conserving battery power.
If the power supply has been interrupted, e.g. ifyou reconnect the battery, you will have to:
Rreset the function for automatically folding
the exterior mirrors in/out by folding the mir-
rors out once (
Ypage 89)
Rset the clock (see the Digital Operator's Man-
ual)
On vehicles with amultimedia system, the

Charging the battery
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a risk of an explosion.
Particularly avoid fire, open flames, creating
sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting.
Do not lean over abattery.
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 batter-
ies. Wash away battery acid immediately with
plenty of clean water and seek medical atten-
tion.
GWARNING
Ad ischarged battery can freeze at tempera-
tures below freezin gpoint. When jump-start-
ing 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.
!Only use battery chargers with amaximum
charging voltage of 14.8 V.
!Only charge the battery using the jump-
starting connection point.
The jump-starting connection point is in the
engine compartment. If the indicator/warning lamps do not light up at
low temperatures, it is very likely that the dis-
charged battery has frozen. In this case, you
may neither charge the battery nor jump-start
the vehicle. The service life of
athawed-out bat-
tery may be shorter .The starting characteristics
can be impaired, particularly at low tempera-
tures. Have the thawed-out battery checked at a
qualified specialist workshop.
Read the battery charger's operating instruc-
tions before charging the battery.
XOpen the hood.
XConnectt he battery charger to the positive
terminal and ground point in the same order
as when connectin gthe donor battery in the
jump-starting procedure (
Ypage 249).

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.

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.
