For safety reasons ,Mercedes–Benz
recommends tha tyou only use batteries that
have been tested and approved for your
vehicle by Mercedes-Benz. These batteries
have greater impact resistanc eand as aresult
there is no risk of acid burns to occupants
when abattery is damaged in an accident.
In order for the battery to achieve the
maximum possible service life, it must always
be sufficiently charged.
Like other batteries, the vehicle battery may
discharge over time if you do not use the
vehicle. In this case, have the battery
disconnected at aqualified specialist
workshop. You can also charge the battery
with acharger recommended by Mercedes-
Benz.C ontactaqualified specialist workshop
for further information.
Have the battery condition of charge checked
more frequently if you use the vehicle mainly
for short trips or if you leave it standin gidle
for alengthy period. Consult aqualified

Jump-starting
For the jump-starting procedure, use only the jump-starting connection point, consisting of a
positive terminal and an earth point, in the engine compartment. G
WARNING
Battery acid is caustic. There is arisk of injury.
Avoid contact with the skin, eyes or clothing. Do not inhale any battery gases. Do not lean over
the battery. Keep children away from batteries. Wash battery acid immediately with water and
seek medical attention. G
WARNING
During charging and jump-starting, explosive gases can escape from the battery. There is arisk
of an explosion.
Particularly avoid fire, open flames, creating sparks and smoking. Ensure there is sufficient
ventilation while charging and jump-starting. Do not lean over abattery. G
WARNING
During the charging process, abattery produces hydrogen gas. If ashort circuit occurs 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
vehicle parts.
R Never place metal objects or tools on abattery.
R It is important that you observe the described order of the battery terminals when connecting
and disconnecting abattery.
R When jump-starting, make sure that the battery poles with identical polarity are connected.
R It is particularly important to observe the described order when connecting and disconnecting
the jumper cables.
R Never connect or disconnectt he battery terminals while the engine is running.G
WARNING
Ad ischarged battery can freeze at temperatures below freezin gpoint .When jump-starting the
vehicle or charging the battery, gases can escape from the battery. There is arisk of an explosion.
Allow the frozen battery to thaw out before charging it or jump-starting.
! Avoid repeated and lengthy startinga ttempts. Otherwise, the catalytic converter could be
damaged by the non-combusted fuel.
If, at low temperatures, the indicator lamps/warning lamps in the instrumentc luster do not
light up, it is highly likely that the discharged battery has frozen .Inthis case you may neither
jump-start the vehicle nor charge the battery. The service life of athawed-out battery may be
shorter. The startingc haracteristics can be impaired, particularly at low temperatures. Have
the thawed-out battery checked at aqualified specialist workshop. Jump-starting
