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).
•If the battery is fully discharged a number
of times, this may shorten 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.
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
•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.

CAUTION
•Avoid waxing or polishing plastic or rub-
ber components
•Polishing chromed strips can wear
away or damage the surface
•Polishes containing abrasive sub-
stances should not be used
Automatic car wash
•We do NOT recommend washing your car
in an automatic wash during the first few
months (because the paint will not have
hardened sufficiently).
•An automatic wash is a simple and quick
way to clean your car, but it is worth
remembering that it may not be as thor-
ough as when you yourself go over the car
with sponge and water. Keeping the under-
body clean is most important, especially in
the winter. Some automatic washers do
not have facilities for washing the under-
body.
CAUTION
•Before driving into an automatic car
wash, turn off the optional rain sensor to
avoid damaging the windshield wipers.
•Make sure that side view mirrors, auxil-
iary lamps, etc, are secure, and that any
antenna(s) are retracted or removed.
Otherwise there is risk of the machine
dislodging them.
•Chromed wheels: Clean chrome-
plated wheels using the same deter-
gents used for the body of the vehicle.
Aggressive wheel-cleaning agents can
permanently stain chrome-plated
wheels.
WARNING
•When the vehicle is driven immediately
after being washed, apply the brakes,
including the parking brake, several
times in order to remove any moisture
from the brake linings.
•Engine cleaning agents should not be
used when the engine is warm. This
constitutes a fire risk.
Exterior lightingCondensation may form temporarily on the
inside of the lenses of exterior lights such as
headlights, fog lights, or taillights. This is nor-mal and the lights are designed to withstand
moisture. Normally, condensation will dissi-
pate after the lights have been on for a short
time.
Polishing and waxing
•Normally, polishing is not required during
the first year after delivery, however, wax-
ing may be beneficial.
•Before applying polish or wax the vehicle
must be washed and dried. Tar spots can
be removed with kerosene or tar remover.
Difficult spots may require a fine rubbing
compound.
•After polishing use liquid or paste wax.
•Several commercially available products
contain both polish and wax.
•Waxing alone does not substitute for pol-
ishing a dull surface.
•A wide range of polymer-based waxes can
be purchased today. These waxes are easy
to use and produce a long-lasting, high-
gloss finish that protects the bodywork
against oxidation, road dirt and fading.
•Do not polish or wax your vehicle in direct
sunlight (the surface of the vehicle should
not be warmer than 113 °F (45 °C).
