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  
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.

MAINTENANCE AND SERVICE  
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.
