The appearance of the engine compartment may vary depending on engine model.
WARNING
The cooling fan (located at the front of the engine compartment, behind the radiator) maystart or continue to operate (for up to6 minutes) after the engine has beenswitched off.
WARNING
Before performing any operations in the engine compartment, the ignition should always be completely switched off (in mode 0,
see Ignition modes (p. 80)) and there should be no remote keys in the passenger compart- ment. The gear selector should be in the P
(park) position. If the engine has been run- ning, wait until it has cooled before touchingany components in the engine compartment. The distributor ignition system operates at very high voltages. Special safety precautionsmust be followed to prevent injury. Alwaysturn the ignition off when:
• Replacing distributor ignition componentse.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintended move-ments and body injury.

CAUTION
•If Oil service required is displayed, the
oil level may be too high. Take the vehicle to an authorized Volvo workshop as soonas possible.
• If the oil level sensor indicates that thelevel is too low, using the correct oil, topup with the amount of oil indicated assoon as possible, see oil specifica-tions (p. 375).
WARNING
Do not allow oil to spill onto or come into con- tact with hot exhaust pipe surfaces.
Electronically checking the oil level
The oil level should be checked at regular inter- vals, particularly during the period up to the firstscheduled maintenance service. To check the oil level:1.
Activate ignition mode II, see Ignition modes
(p. 80).
2. Turn the thumb wheel on the left steering wheel lever until
Oil level is displayed.
> The oil level will be displayed.
NOTE
• The system cannot detect changes in the oil level immediately. The vehicle must bedriven approximately 20 miles (30 km) orhave been parked on level ground withthe engine off for 5 minutes before theoil level reading will be correct.
• If the necessary conditions are not metfor checking the oil level electronically(time interval after the engine wasswitched off, if the vehicle is parked on an incline, etc.),
No values available will
be displayed. This does not indicate a
problem with the oil level sensor.
Engine compartment – coolant
Normally, the coolant does not need to be changed. If the system must be drained, consulta trained and qualified Volvo service technician.
