Maintenance
General information
G
WARNING
Before carrying out maintenance or repair
work, you must read the relevant sections of
the technical documentation relating to main-
tenance and repair measures, e.g. the Oper-
ating Instructions and workshop information.
In particular, first familiarise yourself with the
legal regulations, e.g. work safety and acci-
dent prevention regulations.
You could otherwise fail to recognise dangers
and injure yourself or others.
Always have maintenance work carried out at
a qualified specialist workshop which has the
necessary specialist knowledge and tools to
carry out the work required.
Mercedes-Benz recommends that you use a
Mercedes-Benz or MTU Service Centre for
this purpose. All work relevant to safety or on
safety-related systems must be carried out at
a qualified specialist workshop.
G
WARNING
Maintenance work that is carried out incor-
rectly or not at all, e.g. not changing the oil
filter or not observing maintenance intervals,
can cause engine damage. Engine damage
can lead to an increased risk of accidents.
Therefore, observe the notes on engine main-
tenance in these Operating Instructions.
H
Environmental note
If circumstances demand that you have to do
some maintenance work yourself, environ-
mental protection requirements must be
observed. When disposing of service prod-
ucts, e.g. engine oil, you must comply with the
legal requirements. This also applies to all
parts, e.g. filters, that have been in contact
with service products. For vehicles run on
FAME (fatty acid methyl ester) fuel, the spe-
cial instructions on disposing of engine oil
must be observed. For more information, visit
a qualified specialist workshop, e.g. a
