■Daytime running light system
●Vehicles with a headlight high beam/daytime running lights: The daytime
running lights illuminate using the same lights as the headligh t high beam
and illuminate dimmer than the headlight high beam.
● 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 , (type A only),
* (type B
and C) position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, eve n if the park-
ing brake is set again.
Type A and B: Daytime running lights can be turned off by opera ting the
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 (if equipped)
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.

• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.

ically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■ Camera sensor detection information
●The high beams may not be automatically turned off in the follo wing situa-
tions:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be detected due to repeated curves, road dividers or roadside trees
• When vehicles ahead appear in a faraway lane on a wide road
• When the lights of vehicles ahead are not on
● The high beams may be turned off if a vehicle ahead that is usi ng fog lights
without its headlights turned on is detected.
● House lights, street lights, traffic signals, and illuminated billboards or signs
and other reflective objects may cause the high beams to change to the low
beams, or the low beams to remain on.
● The following factors may affect the amount of time taken for t he high
beams to turn on or off:
• The brightness of the headlights, fog lights, and tail lights of vehicles
ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the r oad surface,
etc.)
• The number of passengers and amount of luggage in the vehicle
● The high beams may turn on or off unexpectedly.
● Bicycles or similar vehicles may not be detected.
● In the following situations the system may not be able to correctly detect the
surrounding brightness level. This may cause the low beams to r emain on
or the high beams to flash or dazzle pedestrians or vehicles ah ead. In such
a case, it is necessary to manually switch between the high and low beams.
