The Automatic High Beam can be operated when
The power switch is in ON mode.
Camera sensor detection information
High beam may not be automatically turned off in the following situations:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When oncoming or preceding vehicles are hidden from sight due to repeated
curves, road dividers or roadside trees
High beam may be turned off if an oncoming vehicle that is using fog lights
without using the headlights is detected.
House lights, street lights, red traffic signals, and illuminated billboards or signs
may cause the high beam to turn off.
The following factors may affect the amount of time taken to turn high beam on
or off:
• The brightness of headlights, fog lights, and tail lights of oncoming and pre-
ceding vehicles
• The movement and direction of oncoming and preceding vehicles
• When an oncoming or preceding vehicle only has operational lights on one
side
• When an oncoming or preceding vehicle is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface etc.)
• The number of passengers and amount of luggage
High beam may be turned on or off when unexpected by the driver.
Small vehicles, such as bicycles, may not be detected.
In the situations below, the system may not be able to correctly detect the sur-
rounding brightness levels, and may flash or expose nearby pedestrians to the
high beam. Therefore, you should 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.
• Surrounding brightness levels are equal to those of headlights, tail lights or
fog lights.
• Vehicles ahead have headlights or tail lights that are either switched off,
dirty, changing color, or have improperly adjusted aim.
• 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 vehicle’s headlights are damaged or dirty.
• The vehicle is listing or titling, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or distress
to other drivers or pedestrians nearby.

2324-3. Operating the lights and wipers
IS300h_EE(OM53B95E)• The vehicle is used in a territory in which vehicles travel on the opposite side
of the road of the country for which the vehicle is approved, for example
using a vehicle designed for right-hand traffic in a left-hand traffic territory,
or vice versa.
CAUTION
Limitations of the Automatic High Beam
Do not rely on the Automatic High Beam. Always drive safely, taking care to
observe your surroundings and turning high beam on or off manually if neces-
sary.
NOTICE
Notes when using the Automatic High Beam system
Do not touch the camera sensor.
Do not subject the camera sensor to a strong impact.

Do not spill liquid onto the camera sensor.
Do not apply window tinting or stickers to the camera sensor or the area of

lights of other vehicles, etc.
Do not install a parking tag or any other accessories near or around the cam-
era sensor.
Do not overload the vehicle.
