Factors the driver can control
The driver should be aware that the following fac-
tors help conserve energy and improve driving
range: • charging the battery regularly
• preconditioning
• Pure drive mode
• climate control settings
• speed and acceleration
• the
Hold function
• tires and tire pressure.
The following table shows the approximate rela-
tionship between constant speed and driving
range. Driving at a lower constant speed helps
increase the electric motor's driving range. Constant speed
100 km/h (62 mph)
50 %
80 km/h (50 mph) 70 %
60 km/h (37 mph) 90 %
50 km/h (31 mph) 100 %
NOTE •
The figures shown in the tables pertain to
a new vehicle.
• None of the figures are absolute and are
affected by e.g. driving style, environment
and other conditions.

In certain situations, it can be useful to control
the hybrid battery's charge level while driving.
This is possible with the Hold and Charge func-
tions, which are available in all drive modes.
Function buttons for Hold and ChargeThe functions can be activated in the center dis-
play's Function view.
Hold
Battery level sustained for
later use.
This function retains the charge
in the hybrid battery for the
electric motor and saves availa-
ble electrical current for use at
a later time, such as when driving in an urban
area or residential neighborhood. Hold is availa-
ble regardless of the hybrid battery's charge level.
The vehicle will function as in normal hybrid driv-
ing with a discharged battery - in addition to
reusing energy from e.g. regenerative braking, the
combustion engine will be used more frequently
to maintain the charge in the battery.

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).

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:

||STARTING AND DRIVING
470
1.
Put the ignition in mode 0.
2. Make sure the auxiliary battery (the battery used to jump start the discharged battery)
has a voltage of 12 volts.
3. If the auxiliary battery is in another vehicle, turn off that vehicle's engine and make sure
that the vehicles are not touching each other.
4. Clamp the red jumper cable onto the auxiliary battery's positive (+) terminal (1).
CAUTION Connect the jump cable carefully to prevent
short circuits with other components in the
engine compartment.
5. Fold back the cover over your vehicle's posi-
tive (+) jump start terminal (2).
6.

Clamp the other end of the red jumper cable
to your vehicle's positive (+) jump start termi-
nal (2).
7. Clamp the black jumper cable onto the auxili- ary battery's negative (-) terminal (3).
8. Clamp the other end of the black jumper cable to your vehicle's negative (-) ground
point (4).
9. Make sure the jumper cables are securely attached to help prevent sparks while jump
starting. 10. Start the engine of the assisting vehicle and
let it run for a few minutes at a higher idling
speed than normal, about 1500 rpm.
11. Start your vehicle's engine. If the engine does not start, allow an additional 10
minutes of charging time and then try to start
the engine again.
NOTE When the engine is started under normal
conditions, the vehicle's electrical drive motor
is prioritized – the gasoline engine remains
off. This means that the electric motor has
"started" and the vehicle is ready to be driven
once the start knob has been turned clock-
wise. Start of the electric motor is indicated
by the indicator lights on the instrument panel
going out and its preselected theme illuminat-
ing.
CAUTION
Do not touch the connections between the
cable and the vehicle during the start attempt.
Risk of sparking. 12. Remove the jumper cables in the reverse
order ‒ first the black cables and then the
red cables.
Make sure that none of the clamps of the
black jumper cables come into contact with
either vehicle's positive (+) jump start termi-
nals or either of the red jumper cable's con-
nected clamps.

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.
15
An authorized Volvo workshop is recommended.

||MAINTENANCE AND SERVICE
616
CAUTION
Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery. The rapid charging function
should not be used as this could damage the
battery.
NOTE
If both the starter battery and the hybrid bat-
tery are discharged, both batteries must be
charged. In such cases, it is not possible to
charge only the hybrid battery first.
The starter battery must have a certain level
of charge for it to be possible to charge the
hybrid battery.
CAUTION Failure to observe the following could cause
the infotainment energy save mode to tempo-
rarily stop working and/or a message in the
driver's display regarding the state of charge
of the starter battery may be temporarily
incorrect after an external starter battery or
battery charger has been connected:
• The negative battery terminal of the vehi-
cle's starter battery must never be used
to connect an external starter battery or
battery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.NOTE If the starter battery becomes discharged too
many times, it will shorten its service life.
The service life of the starter battery is affec-
ted by several factors, such as driving condi-
tions and climate. The starting capacity of the
battery reduces gradually over time. The bat-
tery must therefore be recharged if the vehi-
cle is not used or a long period of time or if it
is only driven short distances. Severe cold fur-
ther limits the starting capacity.
To keep the starter battery in a good condi-
tion, the vehicle should be driven at least
15 minutes per week or the battery should be
connected to a battery charger with automatic
trickle charging.
A starter battery that is always kept fully
charged has the maximum service life.

MAINTENANCE AND SERVICE
619
Hybrid battery
The vehicle's electric motor is powered by a
rechargeable, maintenance-free, lithium-ion
hybrid battery.
NOTE The vehicle cannot be started if the hybrid
battery is discharged.
NOTE
If both the starter battery and the hybrid bat-
tery are discharged, both batteries must be
charged. In such cases, it is not possible to
charge only the hybrid battery first.
The starter battery must have a certain level
of charge for it to be possible to charge the
hybrid battery.
WARNING
Hybrid battery replacement may only be per-
formed by a workshop – an authorized Volvo
workshop is recommended.
CoolantThe hybrid battery's cooling system has its own
expansion tank.
CAUTION Filling the hybrid battery coolant should only
be performed by a workshop – an authorized
Volvo workshop is recommended.
SpecificationsType: Lithium-ion
Power reserve: 10.4 kWh.
NOTE
The capacity of the hybrid battery decreases
with age and use, which could result in
increased use of the combustion engine,
leading to higher fuel consumption and
reduced electric motor range.
