Support battery In addition to the start battery, vehicles equipped with the Start/Stop function also have a supportbattery.
Vehicles with the Start/Stop function are equip- ped with two 12-volt batteries ‒ a heavy-duty
start battery and a support battery that provides extra current during the Start/Stop function'sstart sequence.
The support battery is located in a box next to the spring strut in the engine compartment.
NOTE
• The higher the current consumption in the vehicle, the more the alternator has towork and the batteries have to becharged = increased fuel consumption.
• When the starter battery capacity hasdropped below the lowest permissiblelevel, the Start/Stop function is disen-gaged.
When the Start/Stop function is temporarily reduced due to high current consumption:
• The engine will auto-start, even if the driverdoes not lift their foot from the brake pedal.
The support battery does not normally requiremore service than the start battery. If you have any questions or concerns, consult a workshop ‒
an authorized Volvo workshop is recommended.
CAUTION
If the following is not observed, the Start/ Stop function may temporarily stop workingafter connection of an external starter batteryor battery charger: • The negative battery terminal of the vehi- cle's starter battery must
never be used
to connect an external starter battery orbattery charger – only the vehicle's neg-
ative charging point should be used as
a grounding point.
