331 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 82) 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.
1Does not apply to vehicles with the optional keyless drive.

Location of the washer fluid reservoir
The windshield and headlight washers share a
common reservoir.
The washer fluid reservoir is located on the
driver's side of the engine compartment. Dur-
ing cold weather, the reservoir should be filled
with windshield washer solvent containing
antifreeze. For capacities, see page 359.

333 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
Recycle properly
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 the number of starts, driv-
ing conditions and climate. Extreme coldmay 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
battery.
CAUTION
The infotainment system's energy-saving
feature may not function correctly or at all,
and/or a message may be displayed if a
battery charger or jumper cables are not
connected properly.
•The negative terminal on the battery
must never be used to connect a
jumper cable or a battery charger. Only
the ground point on the chassis may be
used.
See page 113 for an illustration and addi-
tional information.

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.

08 Maintenance and specifications
Fuses

336
Replacing fuses
There 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, a special fuse removal tool is
located on the inside of the engine com-
partment fuse box cover.
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.
