272Service and maintenanceEngine 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 3 275.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
cold regions with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °C. This concentrationshould 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.
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 and clutch fluidOver time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
