Headlight Dimmer And Turn Signal Switch; Automatic Headlight Leveling System - Lexus GS300 1998 Owner's Manual

Automatic headlight leveling system (Vehicles
with discharge headlight only)
12G012
As the headlight beam level is always maintained
automatically at the proper level in all loading conditions,
your headlights do not dazzle other road users.
If this system fails, the warning light in the instrument cluster
comes on. If this occurs, have your vehicle checked by Lexus
dealer.
