used to drive the vehicle.
This mode allows you to drive in res-
idential areas early in the morning
and late at night, or in indoor park-
ing lots, etc., without concern for
noises and gas emissions.
However, when the vehicle proxim-
ity notification system is active, the

●To make your vehicle more visible to
other drivers during daytime driving, the
daytime running lights turn on automati-
cally when all of the following conditions
are met. (The daytime running lights are
not designed for use at night.)
• The hybrid system is started
• The parking brake is released
• The headlight switch is in the (Can-
ada only), or (when the sur-
roundings are bright) position

●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 detect-
ing the level of ambien t light and may cause
the automatic headlight system to malfunc-
tion.
