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.
GWarning!
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.
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.

Jump startingGWarning!
Failure to follow these directions will cause damage to the electronic components, and 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 transmission which
is not covered by the Mercedes-Benz Limited Warranty.
! 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 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.
The battery is located in the engine compartment on the passenger side.

Towing the vehicle
Safety notes
Mercedes-Benz recommends that the vehicle
be transported with all wheels off the ground
using flatbed or appropriate wheel lift/dolly
equipment. This method is preferable to other
types of towing.
! To prevent damage during transport, do
not tie down vehicle by its chassis or
suspension parts.
If circumstances do not permit the
recommended towing methods, the vehicle
may be towed with all wheels on the ground
or rear axle raised only so far as necessary to
have the vehicle moved to a safe location
where the recommended towing methods
can be employed.
! Before towing the vehicle observe the
following instructions:
RDo not tow-start the vehicle. You could
otherwise seriously damage the
transmission which is not covered by the
Mercedes-Benz Limited Warranty.
RDo not tow with sling-type equipment.
Towing with sling-type equipment over
bumpy roads will damage radiator and
supports.
RTowing 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.
