I downloaded the PDF owner's manual https://www.volvocars.com/us/own/owner- ... rs-manuals for the car and it explained the headlight functions as follows:
Headlights, parking lights
O All lights off
Models with daytime running lights: Low beam headlights will automatically come on if the ignition key is in position II. Front and rear parking lights and license plate lights will also be on.
Volvo recommends the use of daytime running lights. If, however, you would prefer to have these lights turned off (USA only), please consult your Volvo retailer. Please note that the use of daytime running lights is mandatory in Canada.
Parking lights on
Headlights, parking lights, license plate lights and instrument panel illumination are on if the ignition key is in position II. If the headlight switch is in position all lights will go out when the ignition is switched off.
The headlight switch must be in this position before the high beams will function.
Switch from high to low beams and vice versa by pulling the turn signal switch lever on the left side of steering column toward you.
