Engine oil change, oil filter change
Have a workshop change the oil at the
specified service intervals.
We recommend that you use genuine
engine oil filters.
Diesel fuel filter
On each engine oil change, have the fuel
filter checked for any water residue by a
workshop.
Illumination of A indicates water in the
fuel filter3.
Have fuel filter checked at shorter intervals
if the vehicle is subjected to extreme
operating conditions such as high humidity
(primarily in coastal areas), extremely high
or low outside temperatures and
substantially varying daytime and night-
time temperatures.
Coolant
The glycol-based coolant provides
excellent corrosion protection for
the heating and cooling systems as
well as antifreeze protection down to
around -28 °C. It remains in the cooling
system throughout the year and need
not be changed.
Use of certain antifreezes can lead to
engine damage. We therefore recommend
that you only use antifreezes that have
been approved.
9 Warning
Drained engine oil cans cannot be
disposed of with domestic refuse.
Observe the legal requirements for
disposal of old oil and filters to protect
the environment and your health.
9 Warning
Antifreeze is a danger to health; it must
therefore be kept in the original container
and out of the reach of children.
