To make your vehicle more visible to other drivers, the parking lights turn on automati-
cally whenever the engine is started and th

■Automatic headlight leveling system
The level of the headlights is automatically ad justed according to the number of passen-

■If the automatic headlight leveling system warning light flashes
It may indicate a malfunction in the system. Contact your Lexus dealer.
■Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features P. 5 7 8 )
The sensor may not function properly if an
object is placed on the sensor, or anything that
blocks the sensor is affixed to the windshield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
