aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fueled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 197.
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
3 197.
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 3 197.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only silicate-free long life coolant
(LLC) antifreeze.
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 corrosion
protection or seal against minor leaks
can cause function problems. Liability
for consequences resulting from the
use of additional coolant additives will be rejected.
Brake and clutch fluid Only use high-performance brake
fluid approved for the vehicle, consult your workshop.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should therefore be replaced at the specified
interval.
