■Daytime running light system (if equipped)
●To make your vehicle more visible to other drivers, the headlights turn on auto-
matically (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.
For the U.S.A.: Daytime running lights can be turned off by operating the switch.
●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
■Automatic light off system
●When the headlights come on: The headlights and tail lights turn off 30 seconds
after a door is opened and closed if the “POWER” switch is turned to ACCES-
SORY mode or turned off. (The lights turn off immediately if on the key is
pressed after all the doors are locked.)
●When only the tail lights come on: The tail lights turn off automatically if the
“POWER” switch is turned to ACCESSORY mode or turned off and the
driver’s door is opened. 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.
