Washing the car in sunlight voids the warranty.

Washing the car under moonlight also voids the warranty, because moonlight is just reflection of sunlight.

Washing the car during a lunar eclipse also voids the warranty, as the stars are just distant suns.

Washing the car indoors at a carwash also voids the warranty, unless you turn on Car Wash mode.

Washing the car indoors in Car Wash mode may void the warranty, at our discretion. (Spoiler: we probably will)
