■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
• When oncoming or preceding vehicles are hidden from sight due to
repeated curves, road dividers or roadside trees
• When oncoming vehicles appear from the faraway lane on wide road
• When oncoming or preceding vehicles have no lights
●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
preceding vehicles
• The movement and direction of oncoming and preceding vehicles
• When a oncoming or preceding vehicle only has operational lights on one
side
• When a 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.

● 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 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.
• 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.
WARNING
■ Limitations of the Automatic High Beam

WARNING
■Caution regarding the use of windshield wipers in AUTO mode (vehi-
cles with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in AUTO mode. Take care that your fin-
gers etc. do not become caught in the windshield wipers.
■ Caution regarding the use of washer fluid
When it is cold, do not use the washer fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
■ When the windshield is dry
Do not use the wipers, as they may damage the windshield.
■ When the washer fluid tank is empty
Do not operate the switch continually as the washer fluid pump may over-
heat.
■ When a nozzle becomes blocked
In this case, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
■ To prevent 12-volt battery discharge
Do not leave the wipers on longer than necessary when the hybrid system
