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 3 228.
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 frostprotection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant provides frost protection down to
approx. -37 °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 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.

of the vehicle. This enables the
workshop to offer you efficient
maintenance and repair, tailored to
your individual vehicle, each time you bring it back to the workshop.
The manufacturer will not access
driver's behaviour related information
about a crash event or share it with
others except:
■ with the consent of the vehicle owner or, if the vehicle is leased, of
the lessee
■ in response to an official request of
police or similar government office
■ as part of the manufacturer's defense in case of legal
proceedings
■ as required by lawIn addition, the manufacturer may use the collected or received diagnostic
data:
■ for the manufacturer's research needs
■ to make it available for research needs where appropriate
confidentiality is maintained and
need is shown
■ to share summary data which is not
tied to a specific vehicle with otherorganisations for research
purposesRadio Frequency
Identification (RFID)
RFID technology is used in some
vehicles for functions such as tyre
pressure monitoring and ignition
system security. It is also used in
connection with conveniences such
as radio remote controls for door
locking/unlocking and starting, and in-
vehicle transmitters for garage door
openers. RFID technology in Opel
vehicles does not use or record
personal information or link with any
other Opel system containing
personal information.
