Turning on the high beam headlightsWith the headlights on, push the
lever forward to turn on the high
beams.
Pull the lever back to the center
position to turn the high beams off.
Pull the lever toward you to turn
on the high beams.
Release to turn them off. You can
flash the high beams with the head-

■Daytime running light system
●Vehicles with halogen headlights: to make your vehicle more visible to other
drivers, the headlights turn on automatically (at a reduced intensity) whenever
the engine is started and the parking brake is released. Daytime running lights
are not designed for use at night.
Vehicles with discharge headlights: to make your vehicle more visible to other
drivers, the parking lights turn on automatically (at a increased intensity) when-
ever 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 sensorThe 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.
