NOTE
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 star-
ting 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
charging.
A battery that is kept fully charged has a
maximum service life.
Changing
Removal
Switch off the ignition and wait for 5 minutes.
Open the clips on the front cover and
remove the cover.
Release the rubber moulding so that the
rear cover is free.
Remove the rear cover by screwing one
quarter turn and lifting it away.

WARNING
Connect and disconnect the positive and
negative cables in the correct sequence.
Detach the black negative cable
Detach the red positive cable
Detach the ventilation hose from the bat-
tery
Loosen the screw holding the battery
clamp.
Move the battery to the side and lift it up.
Installation
1. Lower the battery into the battery box.2. Move the battery inward and to the side
until it reaches the rear edge of the box.
3. Secure the battery using the battery clamp.
4. Connect the ventilation hose.
5. Connect the red positive cable.
6. Connect the black negative cable.
7. Press in the rear cover. (See Removal).
8. Reinstall the rubber moulding. (See
Removal).
9. Reinstall the front cover and secure it with
the clips. (See Removal).
Eco Start/Stop DRIVe*
The car is equipped with two 12 V batteries -
an extra heavy-duty battery for starting and a
support battery which assists the
Eco Start/Stop DRIVe function's starting
sequence.

NOTE
•The higher the current take-off in the car
(extra cooling/heating, etc.) the more
the batteries must be charged =
increased fuel consumption.
•When the capacity of the battery has
fallen below the lowest permissible level
then the Start/Stop function is disen-
gaged.
Temporarily reduced Start/Stop function due
to high current take-off means:
•The engine auto-starts1 without the driver
depressing the clutch pedal.
1Auto-start can only take place if the gear lever is in neutral position.

Battery for starting2 2. Support battery.
The support battery normally requires no more
service than the normal battery that is used for
starting.
IMPORTANT
If the following instruction is not observed
then the Start/Stop function may cease to
work after the temporary connection of an
external battery or battery charger:
•The negative battery terminal on the
car's battery must never be used for
connecting an external battery or bat-
tery charger - only the car chassis may
be used as the grounding point.
See the section "Start assistance" in "Star-
ting and driving" - where there is a descrip-
tion of how the cable clamps must be fitted.
NOTE
If the battery has become so discharged
that everything is "black" and in principle
the car does not have all the normal electri-
cal functions and the engine is subsequently
started using an external battery or battery
charger, then the Start/Stop function will be
activated. It will then be possible 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 inade-
quate 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 temperature a
charging time of 3-4 hours is recom-
mended. The recommendation is that the
battery is charged using an external battery
charger.
If this is not possible then the recommen-
dation is to temporarily deactivate the func-
tion until the battery has been adequately
recharged.
For more information about recharging the
battery, see the section "Battery" in the
chapter "Maintenance and service".

Fuses

325 General
All electrical functions and components are
protected by a number of fuses in order to pro-
tect the car's electrical system from damage 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.
Changing1. 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 signifi-
cant damage to the electrical system and
possibly lead to fire.

under (A).
•Fuses 1-7 and 42-44 are of the "Midi Fuse"
type and must only be replaced by a work-
shop
1.
•Fuses 8-15 and 34 are of the "JCASE" type
and should be replaced by a workshop1.
•Fuses 16-33 and 35-41 are of the "Mini
