Contact aMercedes-Benz Service Centr efor
information and availability. Read the battery
charger's operatin ginstructions before charg-
ing the battery.
If the warning and indicator lamps do not light up on the instrument cluster when temperatures
are low, it is probably because the discharged battery has frozen. In this case, you may neither
jump-start the vehicle nor charge the battery.
The servic elife of abattery that has been
thawed may be reduced. The starting charac-
teristics may be impaired, especially at low tem- peratures. Have the thawed battery checked at
aq ualified specialist workshop. Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of apos-
itive terminal and an earth point, in the engine compartment. G
WARNING
Batterya cid is caustic. There is arisk of injury.
Avoid contact with the skin, eyesorc lothing. Do not breathe in any battery gases. Do not leano ver
the battery .Keep the batterie sout of the reach of children. Immediately rinse off battery acid
thoroughly with plenty of clea nwaterand seek medical attention at once. G
WARNING
During charging and jump-starting, explosive gase scan escap efrom the battery .There is arisk
of an explosion.
Particularl yavoidfire, naked flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not leano verabattery. G
WARNING
During the charging process ,abattery produces hydrogen gas. If ashort circui toccurs or sparks
are created ,the hydrogen gas can ignite. There is arisk of an explosion.
R Make sure that the positive terminal of aconnected battery does not come into contact with
vehicl eparts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminal swhen connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery pole swith identical polarity are connected.
R It is particularl yimportant to observe the described order when connecting and disconnecting
the jump leads.
R Never connect or disconnect the battery terminal swhile the engine is running. G
WARNING
Ad ischarged battery can freeze at temperatures below freezing point. When jump-starting the
vehicl eorcharging the battery ,gase scan escap efrom the battery .There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
If the warning and indicator lamp sdonot light up on the instrument cluster when temperatures are
low,itisp robably because the discharged battery has frozen. In this case, you may neither jump-
start the vehicl enor charge the battery .The service life of abattery that has been thawe dmay be Jump-starting

reduced. The starting characteristics may be impaired, especially at low temperatures. Have the
thawe dbattery checked at aqualified specialist workshop.
Do not use arapidc harging device to start the vehicle. If yourv ehicle's battery is discharged, the
engine can be jump-started from another vehicl eorfromasecond battery using jump leads.
Observe the following points:
R The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible, jump-
start the vehicl eusing adonor battery or ajump-starting device.
R Do not start the engine if the battery is frozen. Let the battery thaw first.
R Jump-starting may be performe donly using batterie swithanominal voltag eof12V.
R Use only jump leads that have asufficient cross-section and insulated terminal clamps.
R If the battery is full ydischarged, leave the battery that is being used to jump-start connected for
af ew minutes before attempting to start. This charge sthe empty battery alittle.
R Make sure that the two vehicles do not touch.
Make sure that:
R The jump leads are not damaged.
R Non-insulated parts of the terminal clamp sdonot come into contact with other metal parts while
the jump leads are connected to the battery.
R The jump leads cannot come into contact with parts that can move when the engine is running,
such as the V-belt pulley or the fan.

tsafety notes G
WARNING
Safety-relevant function sare restricted or not
available if:
R the engine is not running.
R the brake system or the power steering is
malfunctioning
R the voltag esupply or the vehicle's electrical
system is malfunctioning.
If yourv ehicleist owed,s ignificantly greater
force may be required to steer the vehicl eor
to brake. There is arisk of an accident.
In such circumstances, use atowing bar.
Make sure that the steering is moving freely
before towing. G
WARNING
If the steering whee llock is engaged, the vehi-
cle can no longer be steered .There is arisk of
an accident.
Always switch on the ignitio nwhen towing
with atow rope or atowing bar. G
WARNING
When towing or tow-starting another vehicle
and its weight is greater than the permissible gross weight of yourv ehicle, the:
R towing eye may be torn off
R car/trailer combination may swerve or
even overturn
There is arisk of an accident.
When towing or tow-starting another vehicle,
its weight should not be greater than the per- missible gross weight of yourv ehicle.
Detail sonthe permissible gross vehicl eweight
of yourv ehiclecan be found on the vehicl eiden-
tification plate (Y page249).
! You may tow the vehicl
efor am aximu mof
50km. Atowing spee dof50km/h must not
be exceeded.
For towing distances over 50 km, the entire
vehicl emust be lifted up and transported.
! Only secure the tow cabl
eortowing bar to
the towing eyes. You coul dotherwise damage
the vehicle.
! Observe the following points when towing
with atow rope:
R Secure the tow rope on the same side on
both vehicles.
R Make sure that the tow rope is not longer
than legally permitted. Mark the tow rope in the middle, e.g. with awhite cloth Towin

The antifreeze/corrosion inhibitor concentra-
tion in the engine cooling system should:
R be at least 50%. This will protec tthe engine
cooling system against freezin gdown to
approximately -37 †.
R not exceed 55% (antifreez eprotection down
to -45 †). Heat will otherwise not be dissipa-
ted as effectively.
Mercedes-Benz recommends an antifreeze/
corrosion inhibitor in accordanc ewith MB Spec-
ifications for Servic eProducts 310.1.
i When the vehicle is first delivered, it is filled
with acoolant mixture that ensures adequate
antifreeze and corrosion protection.
i The coolant is checked at specified intervals
at aq ualified specialist workshop. Windscreen and headlamp cleaning
