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

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.

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. !

can lead to a battery explosion and severe
injury or death.
Never
lean over batteries while connecting or
jump starting. 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.
Attempting to jump start a frozen battery can
result in it exploding, causing personal injury.
Read all instructions before proceeding.
! Do not tow-start the vehicle. You could
otherwise seriously damage the automatic
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
! Jump starting should only be performed
using the jump-start terminals located in
the engine compartment.
Avoid repeated and lengthy starting
attempts.
Do not attempt to start the engine using a
battery quick-charge unit. If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter and may
present a fire risk.
Make sure the jumper cables do not have
loose or missing insulation.
Make sure the cable clamps do not touch
any

other metal part while the other end is
still attached to a battery.
If the battery is discharged, the engine can be
started with jumper cables and the fully
charged battery of another vehicle or an
equivalent starter pack. Observe the
following:
R Access to the battery is not possible on all
vehicles. If you cannot access the battery
of the other vehicle, provide jump start
power by an external battery or starter
pack.
R Jump starting should only be performed
when the engine and catalytic converter
are cold.
R Do not jump start the engine or charge the
battery if the battery is frozen. Let the
battery thaw out first.
R Only jump start from batteries with the
same voltage rating (12 V). Jump starting
with a more powerful battery could damage
the vehicle’s electrical system. Such
damage will not be covered by the
Mercedes-Benz Limited Warranty.
R Only use jumper cables with sufficient
cross-section and insulated terminal
clamps.
R Always make sure the jumper cables are
not on or near pulleys, fans or other parts
