Battery
Safety notes
A battery should always be sufficiently
charged in order to achieve its rated service
life. Refer to Maintenance Booklet for battery
maintenance intervals.
If you use your vehicle mostly for short-
distance trips, you will need to have the
battery charge checked more frequently.
When replacing a battery, always use a
battery approved by Mercedes-Benz.
If you do not intend to operate your vehicle
for an extended period of time, contact an
authorized Mercedes-Benz Center about
steps you need to observe. G
Warning!
Observe all safety instructions and
precautions when handling automotive
batteries.Risk of explosion.
Fire, open flames and
smoking are prohibited
when handling batteries.
Avoid creating sparks.
Battery acid is caustic. Do
not allow it to come into
contact with skin, eyes or
clothing.
Wear suitable protective
clothing, especially gloves,
apron and faceguard.
Wear eye protection.
Rinse any acid spills
immediately with clear
water. Contact a physician
if necessary.
Keep children away.
Follow the instructions in
this Operator’s Manual.
A battery contains materials that can harm
the environment if disposed of improperly. A
large 12 V storage battery contains lead.
Recycling of the battery is the preferred
method of disposal. Many states (USA only)
or provinces (Canada only) require sellers of
batteries to accept the old battery for
recycling.
G Warning!
Failure to follow these instructions can result
in severe injury or death.
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.
G Warning!
Do not place metal objects on the battery as
this could result in a short circuit.
Use leak-proof batteries only to avoid the risk
of acid burns in the event of an accident.
Take care that you do not become statically
charged, e.g. by wearing synthetic clothing or
rubbing against textiles. For this reason, you
also should not pull or push the battery over
carpets or other synthetic materials.
Never touch the battery first. First touch the
outside body of the vehicle in order to release
any possible electrostatic charges.

Do not rub the battery with rags or cloths. The
battery could explode if touched due to
electrostatic charge or due to spark
formation.
! 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-removable. Do not
attempt to open the battery as otherwise
the battery will be damaged.
VRLA batteries do not require topping-up of
the electrolyte level. They cannot be
opened to check the electrolyte level.
However, the battery condition must be
checked periodically by performing a
battery conductance test. Refer to
Maintenance Booklet for battery condition
testing intervals.
The factory-equipped battery may only be
replaced with a battery that
R has the same security features
R is of identical size
R is of identical voltage
R is of identical capacity
! As any other battery, the battery may
discharge if you do not operate the vehicle
for an extended period of time. Have the
battery disconnected at a qualified
workshop or an authorized Mercedes-Benz
Center in such a case. You may also
connect an accessory battery charge unit
expressly approved by Mercedes-Benz for
your vehicle model to maintain 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 or
KEYLESS-GO button is in position 1.
Otherwise the alternator and other
electronic components could be severely
damaged.
Have the battery checked regularly at an
authorized Mercedes-Benz Center.
Refer to Maintenance Booklet for
maintenance intervals or contact an
authorized Mercedes-Benz Center for
further information.
i After battery power was interrupted, do
the following:
R Synchronize the power windows
(Y page 95).
R Synchronize the tilt/sliding sunroof
(Y page 154). Charging the battery
G
Warning!
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
charging and could cause an explosion that
may

result in personal injury, paint damage or
corrosion.
An accessory battery charge unit specially
adapted for Mercedes-Benz vehicles and
tested and approved by Mercedes-Benz is
available. It permits the charging of the
battery in its installed position. Contact an
authorized Mercedes-Benz Center for
information and availability.
Charge battery in accordance with the
separate instructions for the accessory
battery charger.
Have the battery charged at an authorized
Mercedes-Benz Center. If you charge the Battery
