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 electri- cal components and systems. However, thehybrid battery is used to start the gasolineengine. The start battery should only be replaced by a trained and qualified Volvo service technician.
The start battery is an Absorbed Glass Mat (AGM) 12-volt battery that is dimensioned foruse in vehicles to support electrical systems andfunctions. The service life of a battery is affected by factors such as driving conditions/style, the number ofstarts, climate, etc. Extreme cold may also furtherdecrease the battery

Negative connection point
Only modern battery chargers should be used to charge the start battery. Quick charge functions should not be used and could damage the bat-
tery. If both the start and hybrid batteries are fully dis- charged, both will have to be charged. Onlycharging the hybrid battery in this situation is notpossible. Before the hybrid battery can becharged, the start battery must be charged to acertain level.
CAUTION
• The infotainment system's energy-saving feature may not function correctly or atall, and/or a message may be displayed ifa battery charger or jumper cables arenot 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.
NOTE
• The service life of the start battery is shortened if it becomes dischargedrepeatedly.
• The service life of the start battery isaffected by factors such as driving condi-tions and climate. Extreme cold may alsofurther decrease the battery's startcapacity.

Fuses The fuses help protect the vehicle's electrical components from overloading or short circuits.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the lists offuses. Doing so could seriously damage oroverload the vehicle's electrical system. Orange wires may only be handled by trained and authorized Volvo service technicians orlicensed electricians. A number of component in the vehicle used high voltage electrical current and can be verydangerous to touch. Do not touch any components that are not clearly described in this owner's information.
If an electrical component fails to function, this may be due to a blown fuse. If the same fuseblows repeatedly, this indicates a problem withthe component, which should be inspected by atrained and qualified Volvo service technician.

Replacing fuses The fuses help protect the vehicle's electrical components from overloading or short circuits.
Fuse replacement1. See the list of fuse boxes for their locations.
2. Pull the fuse straight out and examine it from
the side to see if the curved metal wire in the fuse is intact.
3. If the wire is broken, insert a new fuse of the same color and amperage (written on thefuse).
WARNING
Never use metal objects or fuses with higher amperage than those stated on the followingpages. Doing so could seriously damage oroverload the vehicle's electrical system.
