cables conducting ignition voltage, only
carry out engine compartment checks
(e. g. checking brake fluid or engine oil
level) when the igniti on is switched off.

Engine oil In vehicles fitted with engine oil level
monitoring 3, the engine oil level is
checked automatically 386. We
recommend checking the engine oil level
before embarking on long journeys.
Picture no: 18146s.tif
Check with the vehicle on a level surface.
The engine must be at operating
temperature and switched off for at least
5minutes.

Pull out the dipstick, wipe it clean, insert it
to the stop on the handle, pull out and read
the engine oil level.
Push the dipstick in as far as it will go and
twist it by half a turn.
Different dipsticks are used depending on
engine variant.
When the engine oil level has dropped to
the MIN mark, top up engine oil.

244 Opel Service, maintenanceDiesel fuel filter On the event of engine oil change, have
fuel filter checked for possible water
residue by a workshop.
Illumination of A indicates water in the
fuel filter 3.
Have fuel filter checked at shorter intervals
if the vehicle is subjected to extreme
operating conditions such as high humidity
(primarily in coastal areas), extremely high
or low outside temperatures and
substantially varying daytime and
night-time temperatures.
Coolant The coolant provid es anti-freeze
protection down to approx. -28 C. .
Picture no: 18148s.tif
Antifreeze and corrosion protection
Have the concentration of the radiator
contents tested by a workshop before
winter starts. The amount of
antifreezemust provide protection down to
approx. -28 C. A lower antifreeze
concentration will reduce the amount of
protection from fros t and corrosion. Add
antifreeze if necessary.
If coolant loss is topped up with water,
have concentration checked and add
antifreeze if necessary.
Caution
Only use approved anti-freeze.
Coolant additives used to give addi-
tional protection aga inst corrosion and
prevention against small leaks can lead
to functional problems. No liability is
accepted for damage caused by using
coolant additives.
9
Warning
Antifreeze is a danger to health; it must
therefore be kept in the original con-
tainer and out of the reach of children.
