When replacing the start battery or support
battery in a vehicle with Start/Stop, an
Absorbed Glass Mat (AGM) must be used.

The greater the current consumption in the
vehicle, the more the generator has to oper-
ate and the battery is charged. This increases
fuel consumption.

The engine will auto-start, even if the brake
pedal is depressed.
The support battery does not normally required
more service than the start battery. If questions
arise, consult a Volvo retailer or trained and quali-
fied Volvo service technician.
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.
