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. 74)) 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.

Fuses – introduction
The fuses help protect the vehicle's electrical components from overloading.
There are relay/fuseboxes located in the engine compartment, the passenger compartment andthe trunk. If an electrical component fails to function, this may be due to a blown fuse. The easiest way tosee if a fuse is blown is to remove it. To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, a special fuse removal tool is
located on the inside of the engine com- partment fusebox cover .
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of thesame color and amperage (written on the fuse). If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvoservice technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the followingpages. Doing so could seriously damage oroverload the vehicle's electrical system.

A decal on the inside of the cover shows the positions of the fuses. • Fuses 1 – 15, 34 and 42 – 44 are relays/ circuit breakers and should only be removedor replaced by a trained and qualified Volvoservice technician.
• Fuses 16 – 33 and 35 – 41 may be changedat any time when necessary.
There is a special fuse removal tool on the under-side of the cover.
