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 remove the positive and neg-
ative cables in the correct order.
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.
Cross-stay on the R-Design*
Cross-stay and plenum chamber cover.
Cars with R-Design have a cross-stay that
must be removed before the main battery can
be replaced.
1. Remove the plenum chamber covers on
the right and left-hand sides. Prize carefully
with a plastic knife or similar.
2. Loosen and remove the screws (one on the
right and one on the left-hand side) that
hold the cross-stay.
3. Remove the cross-stay.
> Now the main battery can be removed
in accordance with the previous section.
•Fitting the cross-stay takes place in the
reverse order.

NOTE
Tighten the screws to 30 Nm. Check the
torque with a torque wrench.
Fitting
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. Tighten the clamp that holds the battery.
4. Connect the ventilation hose.
> Check that it is correctly connected to
both battery and outlet in the body.
5. Connect the red positive cable.
6. Connect the black negative cable.
7. Press in the rear cover. (See Removal.)8. Fit the rubber moulding. (See Removal.)
9. Align the front cover and secure it with the
clips. (See removal.)

- see page 391.
Eco Start/Stop DRIVe*
Cars with the Start/Stop function are equipped
with two 12 V batteries - one extra powerful
battery for starting and one support battery
that helps during the Eco Start/Stop DRIVe
function's starting sequence.
For more information on Start/Stop - see
page 127.
For more information on the car's main battery
- see page 120 and 391.

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 starts automatically2 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

Battery for starting3 2. Support battery.
The support 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.
2Automatic starting can only take place if the gear lever is in neutral position.3The battery for starting is described in detail on page 345.

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
Fuses 09
350
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.
