AFS (vehicle with discharge headlights)
AFS (Adaptive Front Lighting System) improves visibility at intersections
and on curves by automatically adjusting the direction of light axis of the
headlights according to vehicle speed and the degree of the tire angle
that are controlled by steering input.
Operates at speeds of 6 mph (10 km/h) or higher.
■Deactivating AFS
Turn the switch OFF to deactivate
AFS.
OFF
ON
■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
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 control system to mal-
function.

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.
■Automatic headlight leveling system (vehicles with discharge headlights)
The level of the headlights is automatically adjusted according to the number of
passengers and the loading condition of the vehicle to ensure that the headlights do
not interfere with other road users.
