If you hold down the ON CALL button in the roof for at least 2 seconds, verbal contact will be established between the Volvo On Call service centre and the driver. The aim of this is to agree on what assistance is required.
You can also phone the Volvo On Call service centre, but the car has to be online for the operator to be able to view the car's status and position.
The ON CALL - and SOS buttons can be deactivated when the car's electrical system is in ignition position I, II or if the engine is running:
Select SOS/On Call button lock to deactivate.
A separate subscription may need to be taken out for the roadside assistance service.
