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).
•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.

06 Maintenance and specifications
Fuses

* Option/accessory, for more information, see Introduction.235 Replacing fuses
There are relay/fuse boxes located in the
engine compartment, the passenger compart-
ment, and the trunk.
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.
