THEFT DETERRENT SYSTEM
17L013
To deter theft of the vehicle, this system is designed to
sound an alarm if any of the doors, trunk or hood is
forcibly unlocked or opened or the battery terminal is
disconnected and then reconnected while the vehicle is
locked.
The alarm blows the horn intermittently, flashes the headlights,
tail lights, turn signal lights and other exterior lights. When the
interior light switch is in the “DOOR” position, the interior lights
also turn on.
After the alarm is activated, when you unlock any door or the
trunk using an ignition key or wireless remote control or smart
key system, the tail lights turn on for about 2 seconds to inform
you that the system was activated.

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.
