When driving
Daytime running light system
The headlights turn on automatically (at a reduced intensity) whenever the
engine is started and the parking brake is released to make your vehicle
more visible to other drivers. Dayt ime running lights are not designed for
use at night.
■Headlight control sensor
■Automatic light off system
The headlights turn off automatically if the engine is stopped and the driver’s door is
opened wh

ile the headlights are turned on.
To turn the headlights on again, turn the key to ON, or turn the light switch off once
and then
back to or position.
■Automatic headlight leveling system
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 other road users.
■Customization
The time it takes for the headlights to automatically turn on or off can be changed.
(  P.384 )
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 detect-
ing the level of ambient light and may cause
the automatic headlight system malfunc-
tion.
