Battery (vehicle)
12 V battery – important safety notes
Special tools and expert knowledge are requiredwhen working on the battery, e.g. removal andinstallation. You should therefore have all workinvolving the battery carried out at a qualifiedspecialist workshop.
GWARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting sys-
tem, the ABS (anti-lock braking 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 steering maneuvers
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car-
ried out at a qualified specialist workshop.
For further information about ABS and ESP®,see (Ypage 65) and (Ypage 68).
All vehicles except vehicles with a lithium-ion battery:
GWARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
The highly flammable gas mixture forms whencharging the battery as well as when jump-start-ing.
Always make sure that neither you nor the bat-tery is electrostatically charged. A build-up ofelectrostatic charge can be caused, for exam-ple:
Rby wearing clothing made from syntheticfibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the car-pet or other synthetic materials
Rif you rub the battery with a cloth
GWARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.

Mercedes-Benz. These batteries provideincreased impact protection to prevent vehicleoccupants from suffering acid burns should thebattery be damaged in the event of an accident.
In order for the battery to achieve the maximumpossible service life, it must always be suffi-ciently charged.
Like other batteries, the vehicle battery maydischarge over time if you do not use the vehicle.In this case, have the battery disconnected at aqualified specialist workshop. You can alsocharge the battery with a charger recommendedby Mercedes-Benz. Contact a qualified special-ist workshop for further information.
Have the battery charge state checked morefrequently if you use the vehicle mainly for shorttrips or if you leave it standing idle for a lengthyperiod. Consult a qualified specialist workshopif you wish to leave your vehicle parked for a longperiod of time.
Remove the SmartKey if you park the vehicleand do not require any electrical consumers.The vehicle will then use very little energy, thusconserving battery power.
Charging the 12 V battery
Vehicles with a lithium-ion battery:
!Only use battery chargers with a maximumcharging voltage of 14.4 V.
All vehicles except vehicles with a lithium-ion battery:
!Only use battery chargers with a maximumcharging voltage of 14.8 V.
GWARNING
During charging and jump-starting, explosive
gases can escape from the battery. There is a
risk of an explosion.

Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of thesame rating, which you can recognize by thecolor and value. The fuse ratings are listed in thefuse allocation chart.
The fuse allocation chart is on the fuse box in thecargo compartment (Ypage 328).
If a newly inserted fuse also blows, have thecause traced and rectified at a qualified special-ist workshop, e.g. an authorized Mercedes-BenzCenter.
!Only use fuses that have been approved forMercedes-Benz vehicles and which have thecorrect fuse rating for the system concerned.Otherwise, components or systems could bedamaged.
!Make sure that no moisture can enter thefuse box when the cover is open.
!When closing the cover, make sure that it islying 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 downfaulty circuits. If a fuse blows, all the compo-nents on the circuit and their functions stopoperating.
