Volvo XC90: Maintenance and service / Battery symbols
There are warning symbols and information on the batteries.


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...
Start batteries and support batteries must be recycled in an environmentally
sound manner at the end of their service life.
Consult a workshop if you are uncertain of how to dispose of this type of waste
‒ an authorized Volvo workshop is recommended...
Other information:

helps prevent the vehicle from rolling backward when starting on an uphill gradient.
When backing up a hill, HSA helps prevent the vehicle from rolling forward.
The function retains pressure from the brake pedal in the brake system for several
seconds after the brake pedal has been released...
