■Daytime running light system (if equipped)
●Bulb type: The daytime running lights illuminate using the same lights as the
headlights and illuminate dimmer than the headlights.
● LED type: The daytime running lights illuminate using the same lights as the
parking lights and illuminate brighter than the parking lights.
● To make your vehicle more visible to other drivers during dayti me driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designe d for use at
night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the (Canada only), or “AUTO”

position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the parking
brake is set again.
● For the U.S.A.: Daytime running lights can be turned off by ope rating the
headlight switch.
● Compared to turning on the headlights, the daytime running ligh t 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.
