Replacing bulbs
06``225
CAUTION
Never touch the glass of bulbs with your fin-
gers. Grease and oils from your fingers
vaporize in the heat and will leave a deposit
on the reflector, which will damage it.
NOTE
•
Always switch off the ignition before
starting to replace a bulb.
•
The optional active Bi-XenonŸ head-
light bulbs contain trace amounts of
mercury. These bulbs should always be
disposed of by a trained and qualified
Volvo service technician.

Battery
06``233 Warning symbols on the battery
Wear protective goggles.Keep away from children.Avoid smoking, open flames,
and/or sparks.See the owner's manual.Contains corrosive acid.Risk of explosion
NOTE
A used battery should be disposed of in an
environmentally responsible manner. Con-
sult your Volvo retailer or take the battery to
a recycling station.Handling•
Check that the battery cables are correctly
connected and tightened.
•
Never disconnect the battery when the
engine is running (for example, when
replacing the battery).
The service life and function of the battery is
influenced by factors such as the number of
starts, discharging, driving style, driving con-
ditions, climatic conditions etc.
Never use a quick charger to charge the bat-
tery.
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.NOTE
The life of the battery is shortened if it
becomes discharged repeatedly.Maintenance•
Regularly check that the electrolyte level is
correct and never fill above the level mark.
•
Check all cells. Use a large screwdriver or
a coin to remove the cell caps. Each cell
has its own maximum and minimum level
mark.
•
If necessary, top up with distilled water to
the battery's maximum mark.
•
Tighten the cell caps thoroughly.

06 Maintenance and specificationsFuses
06236
Replacing fusesThere are relay/fuse boxes located in the
engine compartment, the passenger compart-
ment, and the cargo area.
If an electrical component fails to function, this
may be due to a blown fuse. The easiest way
to see if a fuse is blown is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult
to remove, special fuse removal tools are
located on the inside of the fuse box cov-
ers.
2. From the side, examine the curved metal
wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of the
same color and amperage (written on the fuse).
If fuses burn out repeatedly, have the electrical
system inspected by a trained and qualified
Volvo service technician.
WARNING
Never use metal objects or fuses with higher
amperage than those stated on the follow-
ing pages. Doing so could seriously damage
or overload the vehicle's electrical system.

06 Maintenance and specificationsWheels and tires
06258
Accessing the tire sealing systemThe tire sealing system is stowed under the
floor of the cargo area. To access it:
1. Fold up or remove any protective floor cov-
ering or carpet.
2. Open the floor hatch.
3. Remove the retaining screws.
4. Lift out the foam plastic block holding the
jack and lug wrench.
5. Lift out the tire sealing system.
NOTE
•
The tire sealing system is only intended
to seal holes on the tire’s tread area, not
the sidewall.
•
Tires with large holes or tears cannot be
repaired with the tire sealing system.
WARNING
•
After using the tire sealing system, the
vehicle should not be driven farther than
approximately 120 miles (200 km).
•
Have the tire inspected by a trained and
qualified Volvo service technician as
soon as possible to determine if it can
be permanently repaired or must be
replaced.
•
The vehicle should not be driven faster
than 50 mph (80 km/h) while using a tire
that has been temporarily repaired with
the tire sealing system.
•
After using the tire sealing system, drive
carefully and avoid abrupt steering
maneuvers and sudden stops.
Inflating tiresThe tire sealing system can be used to inflate
the tires. To do so:
1. Park the car in a safe place.
2. The compressor should be switched off.
Ensure that the on/off switch is in position
0 (the 0 side of the switch should be
pressed down).
3. Take out the electrical wire and hose.4. Remove the valve cap from the tire’s infla-
tion valve and screw the hose connector
onto the valve as tightly as possible by
hand.
5. Connect the electrical wire to the nearest
12-volt socket in the vehicle.
6. Start the vehicle’s engine.
WARNING
•The vehicle’s engine should be running
when the tire sealing system is used to
avoid battery drain. Therefore, be sure
the vehicle is parked in a well ventilated
place, or outdoors, before using the sys-
tem.•Children should never be left unattended
in the vehicle when the engine is running.
7. Check the tire’s inflation pressure on the
gauge. Switch off the compressor briefly to
get a clear reading from the pressure
gauge.
8. Refer to the tire inflation tables for the cor-
rect inflation pressure. If the tire needs to
be inflated, start the tire sealing system’s
compressor (press the on/off switch to
position I). If necessary, release air from the
tire by turning the air release knob coun-
terclockwise.

06 Maintenance and specifications
Vehicle care
06``261 Washing the car
WARNING
Be sure that the compressor is not con-
nected to a 12-volt socket while replacing
the container.The following points should be kept in mind
when washing and cleaning the car:•
The car should be washed at regular inter-
vals since dirt, dust, insects and tar spots
adhere to the paint and may cause dam-
age. To help prevent corrosion, it is partic-
ularly important to wash the car frequently
in the wintertime.
•
Avoid washing your car in direct sunlight.
Doing so may cause detergents and wax
to dry out and become abrasive. To avoid
scratching, use lukewarm water to soften
the dirt before you wash with a soft
sponge, and plenty of sudsy water.
•
Bird droppings: Remove from paintwork
as soon as possible. Otherwise the finish
may be permanently damaged.
•
A detergent can be used to facilitate the
softening of dirt and oil.
•
A water-soluble grease solvent may be
used in cases of sticky dirt. However, use
a wash place equipped with a drainage
separator.
•
Dry the car with a clean chamois and
remember to clean the drain holes in the
doors and rocker panels.
•
Tar spots can be removed with kerosene
or tar remover after the car has been
washed.
•
A stiff-bristle brush and lukewarm soapy
water can be used to clean the wiper
blades. Frequent cleaning of the wind-
shield and wiper blades improves visibility
considerably and also helps prolong the
service life of the wiper blades.
•
Wash off the dirt from the underside (wheel
housings, fenders, etc).
•
In areas of high industrial fallout, more fre-
quent washing is recommended.
•
After cleaning the engine, the spark plug
wells should be inspected for water and
blown dry if necessary.NOTE
When washing the car, remember to remove
dirt from the drain holes in the doors and
sills.
CAUTION
•
During high pressure washing, the
spray mouthpiece must never be closer
to the vehicle than 13" (30 cm). Do not
spray into the locks.
•
Dirt, snow, etc., on the headlights can
reduce lighting capacity considerably.
Clean the headlights regularly, for
example when refueling.
•
When washing or steam cleaning the
engine, avoid spraying water or steam
directly on the electrical components or
toward the rear side of the engine. Spe-
cial moonroof cautions:
•
Always close the moonroof and sun
shade before washing your vehicle.
•
Never use abrasive cleaning agents on
the moonroof.
•
Never use wax on the rubber seals
around the moonroof.
Exterior componentsVolvo recommends the use of special cleaning
products, available at your Volvo retailer, for
cleaning colored plastic, rubber, or ornamental
components such as chromed strips on the
exterior of your vehicle. The instructions for
using these products should be followed care-
