MAINTENANCE AND SERVICE

Battery recycle

Fuses and central electrical units

Engine compartment

A used starter battery or support battery

must be recycled in an environmentally sound

manner.

Consult a workshop in the event of uncertainty

about how this type of waste should be dis-

carded - an authorised Volvo workshop is rec-

ommended.

All electrical functions and components are

protected by a number of fuses in order to

protect the car's electrical system from dam-

age by short circuiting or overloading.

WARNING

Fuses in engine compartment (p. 591)

Never use a foreign object or a fuse with an

amperage higher than that specified when

replacing a fuse. This could cause signifi-

cant damage to the electrical system and

possibly lead to fire.

If an electrical component or function does not

work, it may be because the component's fuse

was temporarily overloaded and failed. If the

same fuse fails repeatedly then there is a fault

in the circuit. Volvo recommends contacting

an authorised Volvo workshop for checking.

Replacing a fuse

•

All electrical functions and components are

protected by a number of fuses in order to

protect the car's electrical system from dam-

age by short circuiting or overloading.

1. Look in the fuse diagram to locate the

fuse.

2. Pull out the fuse and check from the side

to see whether the curved wire has blown.

3. If this is the case, replace it with a new

fuse of the same colour and amperage.

WARNING

Never use a foreign object or a fuse with an

amperage higher than that specified when

replacing a fuse. This could cause signifi-

cant damage to the electrical system and

possibly lead to fire.

WARNING

Contact an authorised Volvo workshop

about the fuses not mentioned in the

owner's manual. If replacing the fuse is not

performed correctly, it can cause serious

damage to the electrical systems.
