2-3. Operating the lights and windshield wipers
AFS (vehicles with discharge headlights)AFS (Adaptive Front Lighting System) im proves visibility at intersections
and on curves by automatically adjusting the level of the headlights
according to vehicle speed and the degree of the tire angle that are con-
trolled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■ Deactivating AFS
How to switch: P. 214
The indicator turns on when the AFS is deactivated.
■Daytime running light system
To make your vehicle more visible to other drivers, the headlights turn on automati-
cally (at a reduced intensity) whenever the engine is started and the parking brake
is released. Daytime running lights are not designed for use at night.
■Headlight control sensor
■Automatic light off system
The headlights and tail lights turn off 30 seconds after a door is opened or closed if
the engine switch has been switched to ACC or turned OFF while the headlights
are turned on. (The light turns off i mmediately if the button on the key is
pressed after all doors are locked.)
To turn the lights on again, switch to IG-ON mode, or turn the light switch OFF
once and then back to the or position.
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the wind-
shield.
Doing so interferes with the sensor detecting
the level of ambient light and may cause the
automatic headlight system to malfunction.
