Driving
■AUTO mode can be used when

●Compared to turning on the headlights,
the daytime running light system offers
greater durability and consumes less
electricity, so it can help improve fuel
●If a turn signal light is in use, the daytime
running light, on the same side, is turned
off. For emergency flashers, both are
turned off.
■Headlight control sensor
The sensor may not function properly if an
object is placed on th e sensor, or anything
that blocks the sensor is affixed to the wind-
shield.

porarily is recommended in preventing
dirty air from entering the vehicle interior
and helping to cool the vehicle when the

matically switch depending on the tem-
perature setting or the inside
temperature.
