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 sys-
tem to malfunction.
Air conditioning operation may also be interrupted.

■Conditions in which the light distribution control of the headlights
changes automatically
●When all of the following conditions are met, the high beams will be turned
on automatically and the system will operate:
• The vehicle speed is approximately 15 km/h (9 mph) or more.
*
• There are no vehicles ahead with headlights or tail lights turned on.
• The area ahead of the vehicle is dark.
*: If the vehicle speed is approximately 30 km/h (19 mph) or more, the area in
the direction that the vehicle is turning will be illuminated more brightly than
other areas while driving on a curve.
●When all of the following conditions are met, the variable high beams will
turn on and the distance that the low beams are projected will be adjusted
automatically, depending on the location of vehicles ahead:
• The vehicle speed is approximately 15 km/h (9 mph) or more.
• There are vehicles ahead with headlights or tail lights turned on.
• The area ahead of the vehicle is dark.
●If any of the following conditions is met, the high beams or variable high
beams will be changed to the low beams automatically:
• The vehicle speed is below approximately 15 km/h (9 mph).
• The area ahead of the vehicle is not dark.
• There are many vehicles ahead.
• Vehicles ahead are moving quickly and the high beams may blind the
drivers of the other vehicles.

• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road
dividers or roadside trees
