battery MERCEDES-BENZ SL CLASS 2011 Owner's Guide

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.
GWarning!
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.
GWarning!
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.

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.

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
on the starter battery installed 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 starter 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 batteryof 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, which is not
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
that move when an engine is started or
running.
R Should the battery be drained completely,
let the donating power source charge the
vehicle for several minutes before
reattempting the starting process.
Jump starting should only be performed on
the starter battery. The starter battery is
located in the engine compartment on the
passenger side.XMake sure the two vehicles do not touch.XSwitch off all electrical consumers.XEngage the parking brake.XMake sure the automatic transmission is in

warning lamp comes on and warning
messages appear in the multifunction display
while driving. To brake, the driver must then
apply significantly greater brake pedal
pressure and depress the pedal much further
to obtain the expected braking effect. If
necessary, apply full pressure to the brake
pedal. Brakes are only applied to the front
wheels. Stopping distance is increased! For
more information, see “Electro-hydraulic
brake system” in this in this Operator’s
Manual.
If there is a malfunction in the electro-
hydraulic brake system, we recommend that
the vehicle be transported with all wheels off
the ground using flatbed or appropriate wheel
lift/dolly equipment.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
or one axle raised only so far as necessary to
have the vehicle moved to a safe location
where the recommended towing methods
can be employed.XSwitch off the tow-away alarm before
towing the vehicle with all wheels on the
ground or one axle raised ( Y page 64).
!
Before towing the vehicle observe the
following instructions:
R Do not tow-start the vehicle. You could
otherwise seriously damage the
automatic transmission which is not
covered by the Mercedes-Benz Limited
Warranty.
R Do not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
R Towing of the vehicle should only be
done using the properly installed towing
eye bolt. Never attach a tow cable, tow
rope or tow rod to the vehicle chassis,
frame or suspension parts.
GWarning!
With the engine not running, there is no power
assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle. Adapt your driving accordingly.
! Avoid pulling the vehicle abruptly or
diagonally, since it could result in damage
to the chassis alignment.
! Do not use the towing eye bolt for
recovery, as this could damage the vehicle.
If in doubt, recover the vehicle with a crane.
i If the battery is disconnected or
discharged
R the SmartKey will not turn in the starter
switch
R the automatic transmission will remain in
park position P
