MAINTENANCE AND SERVICE
539
NOTE
If the starter battery has been discharged so
much that the car has no normal electrical
functions and the engine is then jump-started
with an external battery or a battery charger,
the Start/Stop function will continue to be
activated. If the Start/Stop function then
auto-stops the engine shortly after, there is a
great risk that engine auto-start will fail due
to insufficient battery capacity, because the
battery has not had the opportunity to
recharge.
If the car has been jump-started, or if there is
insufficient time to charge the battery with a
battery charger, the recommendation is to
temporarily deactivate the Start/Stop function
until the battery has been recharged by the
car. In an outside temperature of +15 °C, the
battery needs to be charged for at least
1 hour by the car. In a lower outside tempera-
ture, the charging time may increase to
3-4 hours. The recommendation is to charge
the battery using an external battery charger.

Fuses
All electrical functions and components are pro-
tected by a number of fuses in order to protect
the car's electrical system from damage by short
circuiting or overloading.
If an electrical component or function does not
work, it may be because the component's fuse
was temporarily overloaded and failed. If the
same fuse fails repeatedly then there is a fault in
the circuit. Volvo recommends contacting an
authorised Volvo workshop for checking.
