Start battery
The vehicle's electrical system is single pole and
uses the body and engine block as conductors.
The start (main) battery is used to power the
starter motor and other electrical components
and systems.
The start battery should only be replaced by a
trained and qualified Volvo service technician.
The vehicle has an alternating current generator.
The start battery is an Absorbed Glass Mat
(AGM) 12-volt battery that is dimensioned for
use in vehicles with carbon dioxide-reducing
functions such as Start/Stop and to support the
vehicle's various electrical systems and functions.
The service life of a battery is affected by factors
such as driving conditions/style, the number of
starts, climate, etc. Extreme cold may also further
decrease the battery’s starting capacity.
•
Never disconnect the start battery while the
engine is running.
•
Check that the start battery is correctly con-
nected and that the clamps on its terminals
are properly tightened.
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 contact
occurs, flush the affected area immedi-
ately with water. Obtain medical help
immediately if eyes are affected.
