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 3 152.
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 the
vehicle, consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frostprotection 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 fluid Only use DOT4+ brake fluid approved for the vehicle, consult a workshop.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
Brake fluid should be stored in a
sealed container to avoid water
absorption.
Ensure brake fluid does not become contaminated.
