IMPORTANT

•

Harmful if ingested. May cause organ
(kidney) damage.

•

Use ready-mixed coolant as recom-
mended by Volvo. If concentrated liq-
uid is used, make sure that the ratio is
50 % coolant to 50 % water of an
approved quality.

•

Do not mix different coolants.

•

Only new coolant should be used
when replacing major cooling system
components to ensure the system has
sufficient corrosion protection.

•

The engine must only be run with a
well-filled cooling system. Otherwise,
temperatures that are too high may
occur resulting in the risk of damage
(cracks) in the cylinder head.

•

A high content of chlorine, chlorides
and other salts may cause corrosion in
the cooling system.

Bulb replacement

This car is equipped only with LED

16

 lamps

and therefore no replaceable bulbs. Contact a
workshop

15

 if a fault occurs in the lighting.

If a fault occurs in LED

16

 lamps, the entire

lamp unit usually must be replaced.

NOTE

NOTE

Outside lighting such as headlamps and
rear lamps may temporarily have conden-
sation on the inside of the lens. This is nor-
mal, all exterior lighting is designed to
withstand this. Condensation is normally
vented out of the lamp housing when the
lamp has been switched on for a time.

Starter battery

The electrical system is single-pole and uses
the chassis and engine casing as a conduc-
tor.

The starter battery is used to start up the
electrical system and drive electrical equip-
ment in the car. The hybrid battery is used
when the internal combustion engine is
started.

The starter battery should be replaced by a
workshop

17

.

The starter battery is a 12 V AGM battery
(Absorbed Glass Mat), designed for regenera-
tive charging, and to support the functionality
of the car's different systems.

The service life and function of the starter bat-
tery is influenced by factors such as the num-
ber of starts, discharging, driving style, driving
conditions, climatic conditions etc.

•

Never disconnect the starter battery when
the engine is running.

•

Check that the cables to the starter bat-
tery are correctly connected and properly
tightened.

WARNING

•

The battery can generate oxyhydrogen
gas, which is highly explosive. A spark
can be formed if a jump lead is con-
nected incorrectly, and this can be
enough for the battery to explode.

•

Do not connect the jump leads to any
fuel system component or any moving
part. Be careful of hot engine parts.

•

The battery contains sulphuric acid,
which can cause serious burns.

•

If sulphuric acid comes into contact
with eyes, skin or clothing, flush with
large quantities of water. If acid
splashes into the eyes - seek medical
attention immediately.

•

Never smoke near the battery.

Charging points

When connecting an external starter battery or
battery charger, use the car's charging points
in the engine compartment.

The battery terminals on the car's starter bat-
tery in the luggage/cargo area must 

not

 be

used.

Positive charging point

Negative charging point

IMPORTANT

It is not possible to charge another car's
battery by supplying current through the
charging points. Using the charging points
to charge another car's battery may cause
a fuse to blow, which means that the
charging points will stop working.

17

An authorised Volvo workshop is recommended.

||

MAINTENANCE AND SERVICE

632

IMPORTANT

When charging the starter battery, only use
a modern battery charger with controlled
charging voltage. Fast charging function
must not be used since it may damage the
battery.

NOTE

If both the starter battery and the hybrid
battery are discharged then 

both

 batteries

must be charged. In such a case, charging
only the hybrid battery first is not possible.

In order for the hybrid battery to be
charged the starter battery must have a
certain state of charge.

IMPORTANT

If the following instruction is not observed
then the energy saving function for info-
tainment may be temporarily disengaged,
and/or the message in the driver display
about the starter battery's state of charge
may be temporarily inapplicable, following
the connection of an external starter bat-
tery or battery charger:

•

The negative battery terminal on the
car's starter battery must 

never

 be

used for connecting an external starter
battery or battery charger - only the

car's negative charging point

 may be

used as the grounding point.

NOTE

The life of the battery is shortened if it
becomes discharged repeatedly.

The life of the battery is affected by several
factors, including driving conditions and
climate. Battery starting capacity decrea-
ses gradually with time and therefore
needs to be recharged if the car is not used
for a longer time or when it is only driven
short distances. Extreme cold further limits
starting capacity.

To maintain the battery in good condition,
at least 15 minutes of driving/week is rec-
ommended or that the battery is con-
nected to a battery charger with automatic
trickle charging.

A battery that is kept fully charged has a
maximum service life.

Location

The starter battery is located in the cargo area.

WARNING

If the starter battery is disconnected, the

automatic opening and closing function

must be reset to work properly. A reset

must take place for pinch protection to

work.

IMPORTANT

On certain models, the battery is attached
with a retaining strap. Make sure the
retaining strap is properly tightened.

MAINTENANCE AND SERVICE

Hybrid battery

The car is equipped with a hybrid battery for
electric motor operation - a maintenance-free
rechargeable Lithium-ion type battery.

NOTE

The car cannot be started if the hybrid bat-
tery is discharged.

NOTE

If both the starter battery and the hybrid
battery are discharged then 

both

 batteries

must be charged. In such a case, charging
only the hybrid battery first is not possible.

In order for the hybrid battery to be
charged the starter battery 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.

Coolant

The hybrid battery's cooling system has a sep-
arate expansion tank.

IMPORTANT

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.

NOTE

The capacity of the hybrid battery dimin-
ishes 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.

Battery recycle

A used starter battery should be recycled in
an environmentally sound manner – it con-
tains lead.

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.

Location of central electrical units

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.
