WARNING
Remember that the radiator fan (located at
the front of the engine compartment, behind
the radiator) may start automatically some
after the engine has been switched off.
Always have the engine cleaned by a work-
shop - an authorised Volvo workshop is rec-
ommended. There is a risk of fire if the engine
is hot.
WARNING
The ignition system works at a very high and
hazardous voltage. The car's electrical system
must always be in ignition position 0 when
work is being performed in the engine com-
partment.
Do not touch the spark plugs or ignition coil
when the car's electrical system is in ignition
position II or when the engine is hot.

Engine oil
An approved engine oil must be used in order
that the recommended service intervals can be
applied.
Volvo recommends:
IMPORTANT
In order to fulfil the requirements for the
engine's service intervals all engines are filled
with a specially adapted synthetic engine oil
at the factory. The choice of oil has been
made very carefully with regard to service life,
starting characteristics, fuel consumption and
environmental impact.
An approved engine oil must be used in order
that the recommended service intervals can
be applied. Only use a prescribed grade of oil
for both filling and oil change, otherwise there
is a risk of the service life, starting characte-
ristics, fuel consumption and environmental
impact of the car being affected.
If engine oil of the prescribed grade and vis-
cosity is not used, engine related components
may become damaged. Volvo Car Corporation
disclaims any liability for any such damage.
Volvo recommends that oil changes are car-
ried out at an authorised Volvo workshop.
Volvo uses different systems for warning of low/
high oil level or low oil pressure. Certain engine
variants have an oil pressure sensor, and then the
driver display's warning symbol for low oil pres-
sure
is used. Other variants have an oil
level sensor, when the driver is informed via the
driver display's warning symbol and display
