Avensis verso 2005

hmm, ok, some vehicles i.e.mine ,has a courtesy light cancelling bitton swith on the dashboard on the lft end or drivers side, I guess it's so a person(s) can enter or exit the vehicle in a stealth mode.. It's not the dash light dimmer although that switch also controls the interior lights, what drove me crazy was whether or not the lights had been turned off individually when a door was open. If thats possible at all. Won't hur to ck. If you still have the owners book it should say somrthing. It more than likely is something that simple. good luck
