High Beam
WARNING: This page is about a different car, the 2003 Lexus ES 300 and 2002 Lexus ES 300. However, it is still accessible from the selected car via links, so may be relevant.
For high beam, push the lever forward. Pull lever back for low beam. For the headlight flasher, pull lever further back. A Blue light in the instrument cluster indicates high beam or headlight flasher is on. The headlight flasher works even when the headlight switch is off.
