(page 395).
1Positive terminal cover
2Negative terminalWarning!
G
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof battery only to avoid the risk
of acid burns in the event of an accident.
Warning!
G
Failure to follow these instructions can
result in severe injury or death.
Observe all safety instructions and precau-
tions when handling automotive batteries
(page 291).
Never lean over batteries while connecting,
you might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
skin or clothing. In case it does, immediately
flush affected area with water and seek
medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
!
Depending on vehicle production date, the
battery is a Valve-Regulated Lead Acid (VRLA)
battery, also referred to as “fleece” battery.
Such batteries do not require topping-up of the
electrolyte level. VRLA batteries therefore do not
have cell caps and the battery cover is non-re-
movable. Do not attempt to open the battery as
otherwise the battery will be damaged.
Even though VRLA batteries do not require top-
ping-up of the electrolyte level and cannot be
opened to check the electrolyte level, the bat-
tery condition must be checked periodically by
performing a battery conductance test. Refer to
Maintenance Booklet for battery condition test-
ing intervals.
The factory-equipped VRLA battery is
leak-proofed. Only use a battery as replacement
that has the same security features and is of
identical size, voltage, and capacity as the facto-
ry-equipped battery.

!
As with any other battery, disconnect the
battery if you do not intend to operate your vehi-
cle for an extended period of time to prevent bat-
tery discharge or connect an accessory battery
charge unit expressly approved by
Mercedes-Benz for your vehicle model to main-
tain the battery charge. Contact an authorized
Mercedes-Benz Center for further information.
The battery, the battery ventilation hose and the
lateral plug must always be securely installed
when the vehicle is in operation.
!
Never loosen or detach battery terminal
clamps while the engine is running or the
SmartKey is in the starter switch. Otherwise the
alternator and other electronic components
could be severely damaged.
Have the battery checked regularly by an autho-
rized Mercedes-Benz Center.
Refer to Maintenance Booklet for maintenance
intervals or contact your authorized
Mercedes-Benz Center for further information.
Warning!
G

locked in positionP

422 Practical hintsBatteryCharging and reinstalling the battery

Charge battery in accordance with the
instructions of the battery charger
manufacturer.

Reinstall the charged battery. Follow
the previously described steps in re-
verse order.
Reconnecting the battery
Turn off all electrical consumers.

Install the luggage box (
page 395).Batteries contain materials that can harm
the environment if disposed of improperly.
Large 12 volt storage batteries contain
lead. Recycling of batteries is the preferred
method of disposal. Many states require
sellers of batteries to accept old batteries
for recycling.
Warning!
G
Never charge a battery while still installed in
the vehicle unless the accessory battery
charge unit* approved by Mercedes-Benz is
being used. Gases may escape during charg-
ing and cause explosions that may result in
paint damage, corrosion or personal injury.
An accessory battery charge unit* specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available, permitting the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for infor-
mation and availability. Charge battery in
accordance with the separate instructions
for the accessory battery charger*.
!
The battery, its filler caps and the battery
ventilation tube must always be securely in-
stalled when the vehicle is in operation.
!
Never invert the terminal connections!
i
The following procedures must be carried
out following any interruption of battery power
(e.g. due to reconnection):


Set the clock (
page 159) (see COMAND
operator’s manual).


Resynchronize the side windows
(page 209).


Resynchronize the tilt/sliding sunroof
(page 214).

428 Practical hintsFusesThe electrical fuses in your vehicle serve to
switch off malfunctioning power circuits.
If a fuse is blown, the components and sys-
tems secured by that fuse will stop operat-
ing.If a newly inserted fuse blows again, have
the cause determined and rectified by an
authorized Mercedes-Benz Center.
The following aids are available to help you
replace fuses:


Fuse chart
The fuse chart is located in the fuse box
in the passenger compartment
(page 429). The fuse chart explains
the fuse allocation and fuse amperag-
es.


Spare fuses
Spare fuses are located in the vehicle
tool kit in the trunk (
page 393).


Fuse extractor
The fuse extractor is located in the ve-
hicle tool kit in the trunk (
page 393).The electrical fuses are located in different
fuse boxes:


Main fuse box in passenger compart-
ment (
page 429)


Fuse box in trunk (
page 429)
Before replacing fuses:

Apply the parking brake (
page 59).

Make sure the gear selector lever is set
to position P (
page 171).

Turn off all electrical consumers.

Turn off the engine (
page 60).

Remove the SmartKey from the starter
switch.
Vehicles with KEYLESS-GO*:
Open the driver’s door.
Warning!
G
Only use fuses approved by Mercedes-Benz
with the specified amperage for the system
in question and do not attempt to repair or
bridge a blown fuse. Using other than ap-
proved fuses or using repaired or bridged
fuses may cause an overload leading to a
fire, and/or cause damage to electrical
components and/or systems. Have the
cause determined and remedied by an
authorized Mercedes-Benz Center.i
A blown fuse must be replaced by an appro-
priate spare fuse (recognizable by its color or the
fuse rating given on the fuse) of the amperage
recommended in the fuse chart.
Any Mercedes-Benz Center will be glad to advise
you on this subject.
