Starter battery - general
The starter battery is used to drive the starter
motor and other electrical equipment in the
car.
The starter battery is a traditional 12 V bat-
tery.
The service life and function of the starter
battery is influenced by factors such as the
number 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.

in cars
with manual gearbox and AGM
13
in cars
with automatic gearbox.
If the starter battery is replaced, make sure
you replace it with a battery with the same
cold starting capacity and type as the orig-
inal battery (see the label on the battery).
•
The starter battery's container size
should be consistent with the original
battery's dimensions.
•
The starter battery's height is different
depending on size.

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.
•
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.
When charging the starter battery or the
support battery (p. 382), only use a mod-
ern battery charger with controlled charg-
ing voltage. Fast charging function must
not be used since it may damage the bat-
tery.
If the following instruction is not observed
then the energy saving function for info-
tainment system may be temporarily dis-
engaged, and/or the message in the com-
bined instrument panel's information dis-
play about the starter battery's state of
charge may be temporarily 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 chassis may be used as the
grounding point.
See Jump starting with battery (p. 270) for
a description of how the cable clamps
must be attached.
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 fur-
ther 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.

Starter battery - replacement
The starter battery in the car can be replaced
without the help of a workshop.
The starter battery is a traditional 12 V bat-
tery.
Removal
First of all: Take the remote control key from
the ignition switch and wait at least 5 minutes
before any electrical connections are touched
- this is because the car's electrical system
needs to store the necessary information to
control modules.

Battery - Start/Stop
Cars with the Start/Stop function are equip-
ped with a support battery in addition to the
starter battery.
Cars with the Start/Stop function are equip-
ped with two 12 V batteries - one extra pow-
erful starter battery for starting and one sup-
port battery that helps during the Start/Stop
function's starting sequence.
For more information on the Start/Stop func-
tion, see Start/Stop* (p. 281).
For more information on the car's starter bat-
tery, see Jump starting with battery (p. 270).

The higher the current take-off in the
car, the more the alternator must be
working and the batteries charging =
Increased fuel consumption.
•
When the capacity of the starter bat-
tery has fallen below the lowest per-
missible level then the Start/Stop func-
tion is disengaged.
Temporarily reduced Start/Stop function due
to high current take-off means:
•
The engine starts automatically
16
without
the driver depressing the clutch pedal
(manual gearbox).
•
The engine starts automatically without
the driver lifting his/her foot off the foot
brake pedal (automatic gearbox).
Location of the batteries
A: Left-hand drive car. B: Right-hand drive car.
(1) Starter battery

(2) Support battery.
The support battery normally requires no
more service than the normal starter battery.
A workshop should be contacted in the event
of questions or problems - an authorised
Volvo workshop is recommended.
If the following instruction is not observed
then the Start/Stop function may tempo-
rarily cease to work after the connection of
an external battery or battery charger:
•
The negative battery terminal on the
car's starter battery must never be
used for connecting an external bat-
tery or battery charger - only the car
chassis may be used as the ground-
ing point.
See Jump starting with battery (p. 270) for
a description of how the cable clamps
must be attached.

If the battery has become so discharged
that everything is "black" and in principle
the car does not have all the normal elec-
trical functions and the engine is subse-
quently started using an external battery or
battery charger, then the Start/Stop func-
tion will be activated. It will then be possi-
ble for the engine to be auto-stopped but
in the event of an auto-stop the Start/Stop
function may fail to auto-start the engine
due to inadequate capacity in the battery.
The battery must first be charged in order
to ensure a successful auto-start after an
auto-stop. At an outside temperature of
+15 °C the battery needs to be charged for
at least 1 hour. At a lower outside tem-
perature a charging time of 3-4 hours is
recommended. The recommendation is
that the battery is charged using an exter-
nal battery charger.
If this is not possible then the recommen-
dation is to temporarily deactivate the
Start/Stop function until the battery has
been adequately recharged.
For more information on charging the
starter battery, see Starter battery - gen-
Related information

Electrical system
The electrical system is single-pole and uses
the chassis and engine casing as a conductor.
The car has a voltage-regulated AC alterna-
tor.
The size, type and performance of the starter
battery depend on the car's equipment and
function.
If the starter battery is replaced, make sure
you replace it with a battery with the same
cold starting capacity and type as the orig-
inal battery (see the label on the battery).

Fuses - general
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.
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 that
you visit an authorised Volvo workshop for
checking.
Changing
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
significant damage to the electrical system
and possibly lead to fire.
