Driving
■Daytime running light system (if equipped)
●Bulb type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight switch
off or in the “AUTO” position. (illuminate dimmer than the headlights) Day-
time running lights are not designed for use at night.
For the U.S.A.: Daytime running lights can be turned off by operating the
headlight switch.
LED type: To make your vehicle more visible to other drivers during daytime
driving, the daytime running lights turn on automatically whenever the
engine is started and the parking brake is released with the headlight
switch off. 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
headlight 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
The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.
