MAINTENANCE AND SERVICING
520
CAUTION
When connecting an external start battery or
a battery charger, the Start/Stop function may
be temporarily disabled if the negative termi-
nal on the vehicle's start battery is used to
connect an external start battery or a battery
charger. Only the
negative connection point
in the engine compartment may be used as a
ground point.
NOTE
If the start battery is completely discharged
and the vehicle has no normal electrical func-
tions, and the engine is then started using an
auxiliary battery or battery charger, the
Start/Stop function will be activated. The
engine can then be auto-stopped but may not
auto-start again due to an insufficient charge
level in the start battery.
To help ensure auto-start, the start battery
should be charged first. At a temperature of
approx. 60 °F (15 °C), the battery should be
charged for at least 1 hour, preferably using
an external battery charger. At lower tempera-
tures, the battery should be charged for
3–4 hours.
If a charger is not available, it is advisable to
disable the Start/Stop function until the bat-
tery is sufficiently recharged.

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 of
fuses. Doing so could seriously damage or
overload the vehicle's electrical system.
If an electrical component fails to function, this
may be due to a blown fuse. If the same fuse
blows repeatedly, this indicates a problem with
the component, which should be inspected by a
trained and qualified Volvo service technician.
