196 Service and Maintenance
Use of engine oil with only ACEA
A1/B1 or only A5/B5 quality is
prohibited, since it can cause
longterm engine damage under
certain operating conditions.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature

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.
Multi-grade 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

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. -36 °C.
In northern countries with very low
temperatures the factory filled
coolant provides frost protection
down to approx. -50 °C. This
concentration should be maintained
all year round. The use of additional
coolant additives intended 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
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid
should therefore be replaced at the
specified interval.
