225 Battery maintenance
The battery in your vehicle is located under the
floor of the cargo compartment.
Driving habits and conditions, climate, the
number of starts, etc. all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
•Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•If necessary, add distilled water. The level
should never be above the indicator.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
•Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.

WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California

Wash hands after handling.
WARNING
•Never expose the battery to open flame
or electric spark.
•Do not smoke near the battery.
•Battery fluid contains sulfuric acid. Do
not allow battery fluid to contact eyes,
skin, fabrics or painted surfaces. If con-
tact occurs, flush the affected area
immediately with water. Obtain medical
help immediately if eyes are affected.

10. Reinstall the cover and retaining bracket
and screw it securely in place.
NOTE
After the battery has been disconnected or
replaced, lock and unlock the vehicle with
the central locking system's remote key to
reactivate such features as the power win-
dows, moonroof, courtesy lighting, etc.
WARNING
•The battery generates hydrogen gas,
which is flammable and explosive. The
battery is fitted with a ventilation hose
which vents hydrogen gas out of the
battery compartment through a ventila-
tion opening in the bottom of this com-
partment. If the battery must be
replaced, it is essential that the ventila-
tion hose is properly connected to the
battery and that it is routed through the
ventilation opening provided (see illus-
tration).
•Be sure the ventilation hose is free of
debris.
•Only use replacement batteries equip-
ped with a ventilation hose. Consult a
trained and qualified Volvo service tech-
nician.

Replacing bulbs 09
228* Option/accessory, for more information, see Introduction.
When replacing bulbs, keep the following
points in mind:
•Never touch the glass of bulbs with your
fingers. Grease and oils from your fingers
vaporize in the heat and will leave a deposit
on the reflector, which will damage it.
•The optional Active Bending Light bulbs
contain trace amounts of mercury. These
bulbs should always be disposed of by an
authorized Volvo retailer.
The following bulbs should only be replaced by
a trained and qualified Volvo service techni-
cian:
•Active Bending Lights (ABL)
•Daytime running lights (DRL) under the
front bumper
•Turn signals and courtesy lights in the side
door mirrors
•Reading lights and glove compartment
light
•Courtesy (dome) lighting
•Rear parking lights
•Brake lights
•High-mounted brake lights
If a problem occurs with the daytime running
lights (DRL) under the front bumper, the entire
lamp housing will have to be replaced.If a problem occurs with the rear parking lights
or the brake lights, the entire taillight housing
will have to be replaced.
See page 234 for a list of bulb specifications.

WARNING
•The engine should not be running when
changing bulbs.
•If the engine has been running just prior
to replacing bulbs in the headlight hous-
ing, please keep in mind that compo-
nents in the engine compartment will be
hot.
WARNING
Active Bending Lights* - due to the high
voltage used by these headlights, these
bulbs should only be replaced by a trained
and qualified Volvo service technician.

Additional fuses in cargo compartment
(XC90 Executive*)If an electrical component fails to function, it is
possible that a fuse has blown.
The fuse boxes are located in four different
places, see the illustration above.
A label on the inside of each cover indicates the
amperage and the electrical components that
are connected to each fuse.
The easiest way to see if a fuse is blown is to
remove it. Pull the fuse straight out. If a fuse is
difficult to remove, you will find a special fuse
removal tool (and several extra fuses) in the
passenger compartment fuse box on the driv-er's end of dashboard. From the side, examine
the curved metal wire (see the illustration) to
see if it is broken. If so, put in a new fuse of the
same color and amperage (written on the
fuse). Spare fuses are stored in the fuse box in
the engine compartment and the passenger
compartment. If fuses burn out repeatedly,
have the electrical system inspected by a
trained and qualified Volvo service technician.
