Hilfsbatterie
Vehicles with the Start/Stop function are equipped with two batteries – a more powerful 12 V start battery and a support battery that provides stronger current during the function's start sequence.

The 12 V support battery is located in a box next to the spring strut in the engine compartment.

If the vehicle is instead equipped with a 48 V support battery, it is located under the cargo compartment. The box over the 48 V support battery may only be removed by an authorized workshop.
- Verwenden Sie niemals eine 48-V-Hilfsbatterie, um das Fahrzeug zu starten.
- External electrical equipment may not under any circumstance be connected to the 48 V battery.
- Only a workshop may replace or perform service on the 48 V battery – an authorized Volvo workshop is recommended.
- The higher the current consumption in the vehicle, the more the alternator has to work and the batteries have to be charged = increased fuel consumption.
- When the starter battery capacity has dropped below the lowest permissible level, the Start/Stop function is disengaged.
Wenn die Start/Stopp-Funktion aufgrund hohen Stromverbrauchs vorübergehend eingeschränkt wird:
- The engine will auto-start, even if the driver does not lift their foot from the brake pedal.
Die Hilfsbatterie erfordert in der Regel nicht mehr Wartung als die Starterbatterie. Bei Fragen oder Bedenken wenden Sie sich an eine Werkstatt – eine autorisierte Volvo-Werkstatt wird empfohlen.
