• Long-term storage of vehicles with hybrid
batteries (p. 421) Charging current
Charging current is used to charge the hybrid
battery and precondition the vehicle. Charging is
performed by connecting a charging cable
between the vehicle's charging socket and a
120/240 V electrical socket (alternating cur-
rent).
When the charging cable is activated, a message
will be displayed in the instrument panel and an
indicator light in the vehicle's charging socket will
illuminate. Charging current is primarily used for
battery charging, but is also used for precondi-
tioning. The vehicle's start battery is charged
along with the hybrid battery.
CAUTION
Never detach the charging cable from the
120/240 V outlet (AC, alternating current)
while charging is in progress – the
120/240 V outlet could be damaged in such
circumstances. Always interrupt charging first
and then disconnect the charging cable – first
from the vehicle's charging socket and then
from the 120/240 V outlet.
NOTE •
In extremely cold or hot weather, part of
the charging current is used to heat/cool
the hybrid battery and the passenger
compartment, resulting in a longer charg-
ing time.
• The charging time is longer if precondi-
tioning has been selected. The time
required depends primarily on the ambi-
ent temperature. There are normally several 120/240 V power
consumers in one fuse circuit, which means that
more than one power consumer (e.g. lighting,
vacuum cleaner, electric drill, etc.) may use the
same fuse.

Battery drain
The electrical functions in the vehicle drain the
battery to varying degrees. Avoid using ignition
mode II when the engine is switched off. Use
ignition mode I instead, as this uses less electri-
cal current.
Note that certain accessories may also drain
power from the electrical system. Do not use
functions that use a lot of electrical current when
the engine is turned off. Examples of such func-
tions are: • blower
• headlights
• windshield wipers
• audio system (especially at high volume).
If the starter battery voltage is low, a message is
shown in the driver display. The vehicle's energy-
saving function will then turn off or reduce certain
functions, such as the blower and/or the audio
system.
– Charge the battery by starting the engine
and let it run for at least 15 minutes (driving
charges the battery faster than letting the
engine idle).

• Ignition modes (p. 427) Jump starting using another battery
If the start battery is discharged, current from
another battery can be used to start the vehicle. Jumper cable connecting points.
CAUTION
The charging point of the vehicle is only
intended for jump starting the vehicle in ques-
tion. The charging point is not intended for
jump-starting another vehicle. Using the
charging point to start another vehicle could
cause a fuse to blow, which would cause the
charging point to stop working.
If a fuse has blown, 12 V Battery Fuse failure
Service required will be displayed in the instru-
ment panel. Volvo recommends contacting an
authorized Volvo workshop. To avoid short circuits or other damage, the fol-
lowing steps are recommended when jump star-
ting the battery:

Engine compartment overview
This overview shows some service-related com-
ponents. Some of the components included in the vehi-
cle's electric drive system are located in the
engine compartment. Exercise caution when
accessing the engine compartment and only
touch what is required for normal maintenance.
WARNING Orange wiring may only be handled by quali-
fied personnel.
WARNING
Several components in the vehicle work with
high voltage that can be hazardous in case of
an incorrect procedure.
• Do not touch anything that is not clearly
described in this Owner's Manual.
• Be careful when checking/filling fluids in
the engine compartment. The layout of the engine compartment may vary depend-
ing on model and engine variant.
Coolant expansion tank
Brake fluid reservoir (located on the driver's
side)
Washer fluid filler pipe
11 Fusebox
Air filter
Engine oil filler pipe
WARNING Bear in mind that the cooling fan (located at
the front of the engine compartment behind
the radiator) may start or continue running
automatically up to about 6 minutes after the
engine is turned off.
Always entrust engine washing to a workshop
– an authorized Volvo workshop is recom-
mended. If the engine is hot, there is a risk of
fire.
WARNING
The ignition system works with extremely high
and dangerous voltages. The vehicle electrical
system should always be in ignition mode 0
when work in being performed in the engine
compartment.
Do not touch any spark plugs or ignition coils
when the vehicle electrical system is in igni-
tion mode II or when the engine is warm.

Start battery
The vehicle has a single-pole electrical system
that uses the chassis and engine mount as con-
ductors.
The start battery is used to start the electrical
system and power electrical equipment in the
vehicle. The hybrid battery is used to start the
combustion engine.
The start battery should only be replaced by a
workshop 15
.
The start battery is a 12 V AGM (Absorbed Glass
Mat) battery, dimensioned for regenerative charg-
ing and to support the function of the vehicle's
various systems.
The service life and performance of the start bat-
tery are affected by factors such as driving style,
driving conditions, climate, battery discharges,
number of starts, etc.
• Never disconnect the start battery while the
engine is running.
• Make sure the cables to the start battery are
correctly connected and the clamps are
securely tightened.
WARNING •
Batteries generate hydrogen gas, which
is flammable and explosive.
• Do not connect the jumper cable to any
part of the fuel system or to any moving
parts. Avoid touching hot manifolds.
• Battery fluid contains sulfuric acid. Do not
allow battery fluid to contact eyes, skin,
fabrics or painted surfaces.
• If contact occurs, flush the affected area
immediately with water. Obtain medical
help immediately if eyes are affected.
• Never expose the battery to open flame
or electric spark. Do not smoke near the
battery. Failure to follow the instructions
for jump starting can lead to injury.
Connection points
WARNING PROPOSITION 65 WARNING
Battery posts, terminals, and related accesso-
ries contain lead and lead compounds, chemi-
cals known to the state of California to cause
cancer and reproductive harm. Wash hands
after handling.Use the vehicle's connection points in the engine
compartment to connect an external start battery
or battery charger.
The battery terminals on the car's starter battery
in the luggage/cargo area must not be used.
Positive connection point
Negative connection point
CAUTION
It is not possible to charge another vehicle's
battery by means of current through the
charging points. Using the charging points to
charge another vehicle's battery could cause
a fuse to blow, which would cause the charg-
ing points to stop working.

An authorized Volvo workshop is recommended.

MAINTENANCE AND SERVICE
620Battery symbols
There are warning symbols and information on
the batteries. Wear protective goggles.
See the Owner's Manual for
additional information. Keep batteries away from
children. Batteries contain corrosive
acid. Avoid smoking, open
flames, and/or sparks. Risk of explosion.
Recycle properly.
NOTE
A used start battery contains lead and must
be recycled in an environmentally responsible
manner.

• Hybrid battery (p. 619) Fuses and fuseboxes
All electrical functions and components are pro-
tected by a number of fuses in order to protect
the vehicle's electrical system from damage by
short circuiting or overloading.
WARNING Never use a foreign object or a fuse with a
higher amperage than that specified to
replace a fuse. This could cause significant
damage to the electrical system and possibly
lead to a fire.
WARNING
Orange wiring may only be handled by quali-
fied personnel.
WARNING
Several components in the vehicle work with
high voltage that can be hazardous in case of
an incorrect procedure.
Do not touch anything that is not clearly
described in this Owner's Manual.
If any electrical component or function is not
responding, the component may have blown a
fuse due to temporary overload. If the same fuse
blows repeatedly, there may be a problem with
the component. Volvo recommends contacting an
authorized Volvo workshop to have the compo-
nent checked.
