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 there is a problem somewhere in this system, the message
“CHECK HEADLIGHT” appears on the multi−information
display. At this time, the master warning light comes on and a
warning tone sounds. If the warning message appears, have
your vehicle checked by your Lexus dealer as soon as
possible.
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 tires. 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 tires
turning angle.If you do not want to activate the system, you can cancel
the system.
Adaptive Front Lighting System cancel switch is located in the
switch box.
G12017
Push the button to use the switch box. To cancel the
system, push the “AFS” switch. To turn it on, push it
again.
When the system is canceled, the “AFS OFF” indicator lights
up in the instrument cluster.
If the system fails, the indicator light in the instrument cluster
will flash. If this occurs, have your vehicle checked by your
Lexus dealer.
After operation, be sure to close the switch box to its original
position.

G12005
For signaling turns, move the lever up or down in the
conventional manner.
The engine switch must be selected in “IG−ON” mode.
The turn signal is self−cancelling after a turn, but after a lane
change, you may have to cancel it by hand. You can also signal
a lane change by moving the turn signal lever partway and
holding it there.
If the green light in the instrument cluster flashes faster than
normal, it indicates that the front or rear turn signal bulb has
burned out. If this indicator light does not come on, the fuse
or the indicator light itself has probably failed.
