■Daytime running light system
●To make your vehicle more visible to other drivers, the parking light turn on
automatically (at a increased intensity) whenever the engine is started and the
parking brake is released. Daytime running lights are not designed for use at
night.
●Compared to turning on the headlights, the daytime running light system offers
greater durability and consumes less electricity, so it can help improve fuel
economy.
■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 system to malfunction.
