Automatic headlight leveling system (vehicles with discharge head-
lights)
The level of the headlights is automatically adjusted according to the number
of passengers and the loading condition of the vehicle to ensure that the
headlights do not interfere with other road users.
If the “AFS OFF” indicator flashes (if equipped)
It may indicate a malfunction in the system. Contact any authorized Toyota
dealer or repairer, or another duly qualified and equipped professional.
Customization
Settings (e.g. light sensor sensitivity) can be changed.
(Customizable features: P. 719)
NOTICE
To prevent 12-volt battery discharge
Do not leave the lights on longer than necessary when the engine is not
running.

Automatic High Beam
: If equipped
The Automatic High Beam uses an in-vehicle camera sensor to
assess the brightness of streetlights, the lights of oncoming and
preceding vehicles, etc., and automatically turns high beam on
or off as necessary.

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
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.
Turning the high beam on/off manually

3084-3. Operating the lights and wipers
UK_AURIS/AURIS_HV_EE (OM12E33E)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 inside rear view mirror or camera sensor is deformed or dirty.
• 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 vehicle’s headlights are damaged or dirty.
• The vehicle is listing or tilting, due to a flat tire, a trailer being towed etc.
• The driver believes that the high beam may be causing problems or dis-
tress to other drivers or pedestrians nearby.

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 nec-
essary.
NOTICE
Notes when using the Automatic High Beam system
Do not touch the camera sensor.
Do not subject the inside rear view mirror or the camera sensor to a strong
impact.
Do not disassemble the camera sensor.
Do not spill liquid onto the inside rear view mirror or the camera sensor.
Do not apply window tinting or stickers to the camera sensor or the area of
windshield near the camera sensor.
Do not place items on the dashboard. There is a possibility that the cam-
era sensor will mistake items reflected in the windshield for streetlights,
the headlights of other vehicles, etc.
Do not install a parking tag or any other accessories near or around the
inside rear view mirror and the camera sensor.
Do not overload the vehicle.
Do not modify the vehicle.
Do not replace windshield with non-genuine windshield.

the lever is pulled and held, the
headlight cleaners will operate
once. After this, the headlight
cleaners will operate every 5th
time the lever is pulled.
Rain-sensing windshield wipers
When “AUTO” is selected, the wipers will operate automatically when
the sensor detects falling rain. The system automatically adjusts wiper
timing in accordance with rain volume and vehicle speed.

Hybrid model:
The power switch is in ON mode.
Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Even when the wipers are not in “AUTO” mode, wiper operation varies
depending on vehicle speed when the washer is being used (delay until drip
prevention wiper sweep occurs).
Raindrop sensor (vehicles with rain-sensing windshield wipers)
Except hybrid model: If the wiper switch is turned to the “AUTO” position
while the engine switch is in IGNITION ON mode, the wiper will operate
once to show that “AUTO” mode is activated.

The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from the
rising or setting of the sun intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

If the temperature of the raindrop sensor is 90C (194F) or higher, or -15C
(5F) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than “AUTO”.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
windshield washer fluid reservoir.
CAUTION
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.
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
fingers etc. do not become caught in the windshield wipers.
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled
toward you and held continually.
When a nozzle becomes blocked
In this case, contact any authorized Toyota dealer or repairer, or another
duly qualified and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
