■Daytime running light system (if equipped)
To make your vehicle more visible to other drivers, the headlights turn on
automatically (at a reduced intensity) whenever the hybrid system is started
and the parking brake is released. Daytime running lights are not designed
for use at night.
■ Headlight control sensor (if equipped)
The sensor may not function properly if
an object is placed on the sensor, or any-
thing 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 con-
trol system to malfunction.
