Largest possible size.

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-starts

without the driver

depressing the clutch pedal.

Location of the batteries

1. Battery

2. Standby battery.

The standby battery normally requires no more
service than the normal battery that is used for
starting. A workshop should be contacted in
the event of questions or problems - an author-
ised Volvo workshop is recommended.

IMPORTANT

If the following instruction is not observed
then the Start/Stop function may temporar-
ily cease to work after the connection of an
external battery or battery charger:

•

The negative battery terminal on the
car's main battery must never be used
for connecting an external battery or
battery charger - only the car chassis
may be used as the grounding point.

See the section "Start assistance" - for a
description of how the cable clamps must
be attached.

Auto-start can only take place if the gear lever is in neutral position.

The battery is described in detail on page 230.

09 Maintenance and service

Battery

233

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
Start/Stop function until the battery has
been adequately recharged.

For more information about recharging the
battery, see the section "Battery" in the
chapter "Maintenance and service".

09 Maintenance and service

Replacing bulbs

234

General

All bulb specifications are given on page 301.

The following list contains locations of bulbs
and other light sources that are specialised or
unsuitable for changing except at a workshop:

•

Active Xenon headlamps - ABL (Xenon
lamps)

•

Xenon headlamps (Xenon lamps)

•

Daytime running lights (DRL) in the spoiler

•

Direction indicators, door mirror and
approach lighting

•

Reading lamps, courtesy lighting and glo-
vebox lighting

•

General interior lighting in the roof

•

Brake light

WARNING

On cars with Xenon headlamps, the
replacement of Xenon lamps must be car-
ried out at a workshop - an authorised Volvo
workshop is recommended. Working with
Xenon lamps demands extreme caution
because the headlamp is equipped with a
high voltage unit.

IMPORTANT

Never touch the glass part of the bulbs with
your fingers. Grease and oil from your fin-
gers are vaporised by the heat, coating the
reflector and then causing damage.

Changing front bulbs

G019599

All front bulbs (except for fog lamps) are
changed by first removing the lamp housing
from the engine compartment.

Removing the lamp housing

IMPORTANT

Do not pull the electrical cable, only the con-
nector.

forward.

Unplug the connector by pressing down
the clip with a thumb while moving out the
connector with the other hand.

09 Maintenance and service

Fuses

241

General

All electrical functions and components are
fused to protect the car's electrical system
from damage by short circuiting and overload-
ing.

The fuses are in two different locations in the
car:

•

Relay/Fuse box in the engine compart-
ment.

•

Relay/Fuse box in the passenger compart-
ment.

Changing

If an electrical component or function does not
work, it may be because the component's fuse
was temporarily overloaded and blew.

Look in the fuse diagram to locate the fuse.

Pull out the fuse and check from the side
to see whether the curved wire has blown.

If this is the case, replace it with a new fuse
of the same colour and amperage.

Each fuse box has space for several spare
fuses. If the same fuse fails repeatedly then
there is a fault in the component. In which case,
Volvo recommends that you visit an authorised
Volvo workshop for this to be checked.

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.

09 Maintenance and service

Fuses

242

Relay/fuse box in the engine compartment

G007446

The fuse box has 36 fuse positions. Be sure to
replace a blown fuse with a new fuse of the
same colour and amperage.

•

Fuses 19-36 are of the "Mini Fuse" type.

•

Fuses 7-18 are of the "JCASE" type and
should be replaced by a workshop.

•

Fuses 1-6 are of the "Midi Fuse" type and
must only be replaced by a workshop.

On the inside of the cover there are tweezers
that facilitate the procedure for the removal
and fitting of fuses.

An authorised Volvo workshop is recommended.

Relay/Fuse box in the passenger compartment

G020601

The fuse box has 50 fuse positions. The fuses
are located under the glovebox. The box also
provides space for several spare fuses. Tools
for fuse replacement are located in the relay/
fuse box in the engine compartment, see
page 242.

Replacing fuses

Remove the trim concealing the fuse box
by pressing in the pin in the centre of the
clips (1) about one cm and then withdraw-
ing the clips.

Turn the two wing screws (that secure the
fuse box) (2) anticlockwise and remove
them.

Lower the fuse box (3) half way. Pull it
towards the seat until it stops. Lower it

completely. The fuse box can be fully
unhooked.

Close the fuse box in the reverse order.

Remove the pins from the centre of the
clips. Fit the trim and the clips. Reinsert the
pins into the clips. This expands the clips
and secures the trim.
