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 the starter motor and other
electrical equipment in the vehicle.
The start battery should only be replaced by a
workshop
17
.
The vehicle has a voltage-regulated alternating
current generator.
The starter battery is a 12 V battery, designed for
the carbon dioxide reducing functions Start/Stop
and regenerative charging, and to support the
functionality of the car's different 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.
If the start battery is being charged, the support
battery will also be charged.
Negative connection point
Positive connection point
Only a modern battery charger with controlled
charge voltage should be used to charge the
starter battery and support battery. The rapid
charging function should not be used as this
could damage the battery.

MAINTENANCE AND SERVICE
560
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.
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.
Location
The start battery is located in the engine compartment.
WARNING
If the starter battery is disconnected, the func-
tion for automatic opening and closing must
be reset to function correctly. A reset is
required in order for the pinch protection to
work.
On certain models, the battery is secured with
a tensioning strap. Make sure that the ten-
sioning strap is always securely tightened.

Volvo recommends that batteries are replaced by
an authorized Volvo workshop.
When replacing the starter battery or support
battery, a battery of the same type as the pre-
vious battery must be installed.
If replacing the starter battery, make sure you
replace it with a battery with the same cold
start capacity and type as the original battery
(see the decal on the battery).
The size of the starter battery should conform
to the dimensions of the original battery.

Support battery
In addition to the start battery, vehicles equipped
with the Start/Stop function also have a support
battery.
Vehicles with the Start/Stop function are equip-
ped with two 12-volt batteries
‒ a heavy-duty
start battery and a support battery that provides
extra current during the Start/Stop function's
start sequence.
The support battery is located in the engine compart-
ment. The start battery is also shown here (top).
•
The higher the current consumption in
the vehicle, the more the alternator has to
work and the batteries have to be
charged = increased fuel consumption.
•
When the starter battery capacity has
dropped below the lowest permissible
level, the Start/Stop function is disen-
gaged.
When the Start/Stop function is temporarily
reduced due to high current consumption:
•
The engine will auto-start, even if the driver
does not lift their foot from the brake pedal.
The support battery does not normally require
more service than the start battery. If you have
any questions or concerns, consult a workshop
‒
an authorized Volvo workshop is recommended.
If the following is not observed, the Start/
Stop function may temporarily stop working
after connection of an external starter battery
or battery charger:
•
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.
MAINTENANCE AND SERVICE
}}
563
If the starter battery is discharged to the
extent that the vehicle does not have normal
electrical functions and the engine must then
be jump-started with an external battery or a
battery charger, the Start/Stop function may
remain activated. If the Start/Stop function
shortly thereafter auto-stops the engine, there
is a huge risk that auto-start of the engine will
fail due to insufficient battery capacity since
the battery had not had time to recharge.
If the vehicle has been jump-started or if
there has not been enough time for the bat-
tery to be charged with a battery charger, it is
advisable to temporarily deactivate the
Start/Stop function until the battery has been
recharged by the vehicle. At an ambient tem-
perature of about +15°C (about 60°F), the
battery must be charged by the vehicle for at
least one hour. At lower ambient tempera-
tures, the charging time can increase to
3-4 hours. It is advisable to charge the battery
with an external battery charger.

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.
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.
