Adding engine oil
G WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and
touch only the components described in the
following.
G WARNING
If engine oil comes into contact with hot com-
ponents in the engine compartment, it may
ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine.
H Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful to
the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a ser-
vice system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Engine compartment
Products at any Mercedes-Benz Service
center.

R
not been specifically approved for the
service system
replacing engine oil and oil filters after
R
the interval for replacement specified by
the service system has been exceeded
using engine oil additives.
