You can flash the high beams with the headlights on or off.
■Daytime running light system
●Vehicles with halogen headlights: The daytime running lights illuminate
using the same lights as the high beam lights and illuminate dimmer than
the high beam lights.
● Vehicles with LED headlights: The daytime running lights illuminate using
the same lights as the headlights and illuminate dimmer than the headlights.
● To make your vehicle more visible to other drivers during daytime driving,
the daytime running lights turn on automatically when all of the following
conditions are met. (The daytime running lights are not designed for use at
night.)
• The hybrid system is operating
• The parking brake is released
• The headlight switch is in the , or “AUTO”
* position
*: When the surroundings are bright
The daytime running lights remain on after they illuminate, even if the park-
ing brake is set again.
● 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.

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.
Air conditioning operation may also be
interrupted.

Driving
●In the situations below, the system may not be able to correctly detect the
surrounding brightness levels, and may flash or expose nearby pedestrians
to the high beam. Therefore, you s hould consider turning the high beams on
or off manually rather than relying on the Automatic High Beam system.
• In bad weather (rain, snow, fog, sandstorms etc.)
• The windshield is obscured by fog, mist, ice, dirt etc.
• The windshield is cracked or damaged.
• The camera sensor is deformed or dirty.
• The camera sensor temperature is extremely high.
• Surrounding brightness levels are equal to those of headlights, tail lights or fog lights.
• Vehicles ahead have headlights that are either switched off, dirty, are
changing color, or have are not aimed properly.
• When driving through an area of intermittently changing brightness and darkness.
• When frequently and repeatedly driving ascending/descending roads, or roads with rough, bumpy or uneven surfaces (such as stone-paved
roads, gravel tracks etc.).
• When frequently and repeatedly taking curves or driving on a winding road.
• There is a highly reflective object ahead of the vehicle, such as a sign or
a mirror.
• The back of a vehicle ahead is highly reflective, such as a container on a truck.
• The vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The high beam and low beam are repeatedly being switched between in
an abnormal manner.
• The driver believes that the high beam may be causing problems or dis- tress to other drivers or pedestrians nearby.
