Volvo is doing some cool things.
They have an option to give you your tire pressures on your dash display.
They have an optional to cycle through all your lights as you do your walk around.
Last month I got a SHORT IN RIGHT BREAK LIGHT message. The bulb had failed,the brake light filament was touching the tail light filament.
It was mid-trip and may have saved me a ticket as it was fine on the pre-trip.
