Headlight Dimmer & Turn Signal Switch
WARNING: This page is about a different car, the 2003 Lexus RX 300 and 2002 Lexus RX 300. However, it is still accessible from the selected car via links, so may be relevant.
For high beam, push the lever forward. Pull it back for low beam. For the headlight flasher, pull it further back.
For signaling turns, move the lever up or down in the conventional manner. The ignition key must be in the ON position. The turn signal is self-cancelling after a turn, but after a lane change, you may have to cancel it by hand.
