gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is ar isk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation. G

environmental influence or by animals can
ignite if in contact with the exhaust system or
parts of the engine that heat up. There is arisk
of fire.
Carry out regular checkstom ake sure that
there are no flammable foreign materials in
the engine compartmentorint he exhaust
system.
! Do not depress the accelerator pedal
when startingt he engine.

tube.
X Wipe off oil dipstick 001A.
X Slowly slide oil dipstick 001Ainto the guide
tube to the stop, and take it out again.
If the level is between MIN mark 0023and

WARNING
Certain components in the engine
compartment, such as the engine, radiator
and parts of the exhaust system, can become
very hot. Working in the engine compartment
poses arisk of injury.
Where possible, let the engine cool down and
touch only the components described in the

components in the engine compartment, it
may ignite. There is arisk of fire and injury.
Make sure that engine oil is not spilled next
to the filler neck.L et the engine cool down
and thoroughly clean the engine oil off the
components before starting the engine. H
Environmental note
When adding oil, take care not to spill any. If
oil enterst he soil or waterways, it is harmful
to the environment.

have been approved for vehicles with a
service system. You can obtain alist of the
engine oils and oil filters tested and
approved in accordanc ewith the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
center.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R replacing engine oil and oil filters after
the interval for replacement specified by
the service system has been exceeded
R using engine oil additives.
! Do not add too much oil. adding too much
engine oil can result in damage to the
engine or to the catalytic converter. Have
excess engine oil siphoned off. 282
Engine compartmentMaintenance and care

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
