Service and maintenance223Dexos is the newest engine oil quality
that provides optimum protection for
diesel engines. If it is unavailable,
engine oils of other listed qualities
must be used.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 226.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 226.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade depending on the minimum ambient
temperature 3 226.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free long life coolant (LLC) antifreeze approved for thevehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C.
This concentration should be
maintained all year round. The use of
additional coolant additives that
intend to give additional corrosionprotection or seal against minor leaks
can cause function problems. Liability for consequences resulting from the
use of additional coolant additives will
be rejected.
Washer fluid
Use only washer fluid approved for
the vehicle to prevent damage of wiper blades, paintwork, plastic and
rubber parts. Consult a workshop.
Brake fluid
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified interval.
AdBlue Only use AdBlue to reduce the
nitrogen oxides in the exhaust
emission 3 143.
