the vehicle enters a dark place such as a tunnel or parking
lot according to lighting conditions. In this case, we
recommend you to twist the knob manually to the second
clickstop to turn on the headlights immediately.
When the headlight switch is turned to the first or second

closed with the ignition switch turned to the “ACC” or “LOCK”\
position.* To turn them on again, turn the ignition switch to the
“ON” position, or turn the headlight switch off and then twist the
knob until the first or second clickstop. If you are going to park
for over one week, make sure the headlight switch is off.
When the headlight switch is on with all the doors locked and

Automatic headlight leveling system
The headlight beam level is always maintained automatically
at the proper level in all loading conditions so that your
headlights do not dazzle other road users.
If the system fails, the “AFS OFF” indicator light in the
instrument cluster will flash. If this occurs, have your vehicle
checked by your Lexus dealer.
Adaptive Front Lighting System (AFS)
Adaptive Front Lighting System (AFS) provides the proper
headlight beam level according to the current driving
conditions. This system moves the headlight beam left or right
according to the turning angle of the steering wheel. The
synergy of this system and the automatic headlight leveling
system improves visibility at the intersections and curves.
The system operates when the vehicle speed increases above
10 km/h (6 mph), and stops when the vehicle speed drops
below 10 km/h (6 mph).
The system can operate within the limited range of the steering
wheel turning angle.
