08 Maintenance and specifications
Wiper blades and washer fluid
08

321 Wiper blades
The windshield wiper blades are different
lengths. The blade on the driver’s side is longer
than the one on the passenger side.
Service position
Wiper blades in service position
The wiper blades must be in the vertical (serv-
ice) position for replacement, washing or to lift
them away from the windshield when e.g.,
removing ice or snow. To put them in this posi-
tion:
1.
Switch off the ignition (ignition mode 0, see
page 80) and keep the remote key in the
ignition slot
1.2. Move the right steering wheel lever up and
hold it for at least 1 second. The wipers will
then move to the vertical position on the
windshield.
The wipers can be returned to the normal posi-
tion by briefly switching on the ignition (or by
starting the engine).
Replacing the windshield wiper blades
With the wipers in the service position, fold
out the wiper arm from the windshield.
Press the button on the wiper blade attach-
ment and pull the wiper blade straight out,
parallel with the wiper arm.
Slide in the new wiper blade until it clicks
into place.
Check that the blade is securely in place.
CleaningKeeping the windshield and wiper blades clean
helps improve visibility and prolongs the serv-
ice life of the wiper blades. Clean the wiper
blades with a stiff-bristle brush and lukewarm
soap solution or car washing detergent.

08 Maintenance and specifications
Battery

324
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.
•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 15
minutes 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.
CAUTION
•Always use distilled or deionized water
(battery water).
•Never fill above the level mark in the cell.

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).
CAUTION
Volvo does not recommend the use of long-
life or durable paint protection coatings,
some of which may claim to prevent pitting,
fading, oxidation, etc. These coatings have
not been tested by Volvo for compatibility
with your vehicle's clear coat. Some of them
may cause the clear coat to soften, crack,
or cloud. Damage caused by application of
paint protection coatings may not be cov-
ered under your vehicle's paint warranty.
Cleaning the interior
Only use cleaning agents and car care prod-
ucts recommended by Volvo. Clean regularly
and follow the instructions included with the
car care product.
Upholstery care
Fabric
Clean with soapy water or a detergent. For
more difficult spots caused by oil, ice cream,
shoe polish, grease, etc., use a clothing/fabric
stain remover. Consult your Volvo retailer.
AlcanteraTM suede-like materialSuede-like upholstery can be cleaned with a
soft cloth and mild soap solution.
