Automatic headlight leveling system
(vehicles with discharge headlight only)
Vehicle position changes according to loading condition,
passengers getting on and off, vehicle acceleration and
deceleration, etc. However, as the headlight beam level is
always maintained automatically by the system at the proper
level, 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 your
Lexus dealer.
If you replace the rear suspension and/or the vehicle height
changes, contact your Lexus dealer to check the automatic
headlight leveling system and headlight beam level.
