If the battery is replaced, make sure you
replace it with a battery with the same
size, cold starting capacity and type as the
original battery (see the decal on the bat-
tery).

Hybrid battery
The car is equipped with a hybrid battery for
electric motor operation - a maintenance-free
rechargeable Lithium-ion type battery.
The car cannot be started if the hybrid bat-
tery is discharged.
If both the starter battery and the hybrid bat-
tery are discharged then both batteries must
be charged. In such a case, charging only the
hybrid battery is not possible. In order for the
hybrid battery to be charged, the starter bat-
tery must have a certain state of charge.
WARNING
The hybrid battery must only be replaced
by a workshop - an authorised Volvo work-
shop is recommended.
The service life and capacity of the
hybrid battery
The capacity of the hybrid battery diminishes
with age and use, which may result in
increased use of the internal combustion
engine and, as a consequence, reduced fuel
economy and reduced range during electric
operation.
Coolant
The hybrid battery's cooling system has a sep-
arate expansion tank.
The hybrid battery's coolant must only be
topped up by a workshop - an authorised
Volvo workshop is recommended.
Specifications for hybrid battery
Type:
Lithium-ion
Total amount of energy:
11.6 kWh.

cling.

Battery recycle
A used starter 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.

Fuses and central electrical units
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.
WARNING
Orange-coloured cables must only be han-
dled by qualified personnel.
WARNING
Several components in the car work with
high-voltage current that could be danger-
ous in the event of incorrect intervention.
Do not touch anything that is not clearly
described in the owner's manual for the
car.
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.
