The wiper blades also exit service position if:
•
Windscreen wiping is activated.
•
Windscreen washing is activated.
•
Rain sensor activated.
•
The car is driven away.
If the wiper arms in service position have
been folded up from the windscreen, they
must be folded back down onto the wind-
screen before the activation of wiping, wash-
ing or the rain sensor, as well as before driv-
ing. This is to avoid scraping the paint on the
bonnet.

Replacing a wiper blade
The wiper blades sweep water away from the
windscreen and rear window. Together with the
washer fluid they clean the windows and ensure
visibility for driving. Windscreen and rear window
wiper blades can be replaced.
Replacing a windscreen wiper blade
Fold up the wiper arm when it is in service
position. Press the button located on the
wiper blade mounting and pull straight out
parallel with the wiper arm.
Slide in the new wiper blade until a "click" is
heard.
Check that the blade is firmly installed.
4. Fold the wiper arm back towards the wind-
screen.

The wiper blades are different lengths.
The wiper blades are different lengths. The
blade on the driver's side is longer than on
the passenger side.
Replacing the wiper blade, rear window
1. Fold out the wiper arm.
2. Grip the inner section of the blade (by the
arrow).
3. Turn anticlockwise to use the blade's end
position against the wiper arm as a lever to
detach the blade more easily.
4. Press the new wiper blade into place. You
should hear a click. Check that it is firmly
installed.
5. Lower the wiper arm.
Check the blades regularly. Neglected main-
tenance shortens the service life of the wiper
blades.

Filling washer fluid
Washer fluid is used for cleaning the headlamps
as well as the windscreen and rear window.
Washer fluid with antifreeze must be used when
the temperature is under the freezing point.
Filling of washer fluid takes place in the reservoir
with a blue cap. The reservoir is used for wind-
screen washer, rear window washer and head-
lamp washers
*
When approx. 1 litre of washer fluid remains
in the reservoir the message
Washer fluid
Level low, refill
is shown in the driver display
together with the symbol
.
Prescribed grade: Washer fluid recommended
by Volvo - with frost protection during cold
weather and below freezing point.
Use Volvo genuine washer fluid or equivalent
with a recommended pH of between 6 and 8,
in working dilution (e.g. 1:1 with neutral
water).
Use washer fluid with antifreeze when the
temperature is below freezing to avoid freez-
ing in the pump, reservoir and hoses.
Volume:
•
Cars with headlamp washing: 5.5 litres.
•
Cars without headlamp washing: 3.5 litres.

Starter battery
The electrical system is single-pole and uses the
chassis and engine casing as a conductor.
The starter battery is used to start up the electri-
cal system and drive electrical equipment in the
car. The hybrid battery is used when the internal
combustion engine is started.
The starter battery should be replaced by a
workshop
11
.
The starter battery is a 12 V AGM battery
(Absorbed Glass Mat), designed for the carbon
dioxide reducing functions Start/Stop and regen-
erative charging, and to support the functionality
of the car's different systems.
The service life and function of the starter battery
is influenced by factors such as the number of
starts, discharging, driving style, driving condi-
tions, climatic conditions etc.
•
Never disconnect the starter battery when
the engine is running.
•
Check that the cables to the starter battery
are correctly connected and properly tight-
ened.
11
An authorised Volvo workshop is recommended.
||
MAINTENANCE AND SERVICE
570
WARNING
•
The battery can generate oxyhydrogen
gas, which is highly explosive. A spark can
be formed if a jump lead is connected
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 imme-
diately.
•
Never smoke near the battery.
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 battery in the cargo area must
not be used.
It is not possible to charge another car’s bat-
tery by means of 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.
Positive charging point
Negative charging point
When charging the starter battery, only use a
modern battery charger with controlled charg-
ing voltage. Fast charging function must not
be used since it may damage the battery.
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 first is not possible.
In order for the hybrid battery to be charged
the starter battery must have a certain state
of charge.
If the following instruction is not observed
then the energy saving function for infotain-
ment may be temporarily disengaged, and/or
the message in the driver display about the
starter battery's state of charge may be tem-
porarily inapplicable, following the connection
of an external starter battery 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.
MAINTENANCE AND SERVICE

571
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 cli-
mate. Battery starting capacity decreases
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 recom-
mended or that the battery is connected to a
battery charger with automatic trickle charg-
ing.
A battery that is kept fully charged has a
maximum service life.
The starter battery is located in the cargo area.
The following table shows specifications for the
starter battery.

Volvo recommends entrusting battery replace-
ment to an authorised Volvo workshop.
When replacing the starter battery, a battery
of AGM
12
type must be fitted.
If the starter battery is replaced, make sure
you replace it with a battery with the same
cold starting capacity and type as the original
battery (see the label on the battery).
The starter battery's container size must be
consistent with the dimensions for the origi-
nal battery.

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 battery
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 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 workshop is
recommended.
Coolant
The hybrid battery's cooling system has a sepa-
rate expansion tank.
The hybrid battery's coolant must only be top-
ped up by a workshop - an authorised Volvo
workshop is recommended.

Fuses
All electrical functions and components are pro-
tected by a number of fuses in order to protect
the car's electrical system from damage 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 significant
damage to the electrical system and possibly
lead to fire.
WARNING
Orange-coloured cables must only be handled
by qualified personnel.
WARNING
Several components in the car work with
high-voltage current that could be dangerous
in the event of incorrect intervention.
Do not touch anything that is not clearly
described in this owner's manual.
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.
