Automatic High Beam
Push the lever away from you
with the headlight switch in
or position.
Press the Automatic High
Beam switch.
The Automatic High Beam indica-
tor will come on when the head-
lights are turned on automatically
to indicate that the system is
active.
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.

■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 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.
WARNING
■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.

The pre-collision system is equipped with a sophisticated computer
that will record certain data, such as:• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance and relative speed between your vehicle and the vehicle ahead or other objects)
• Images from the camera sensor (available only when the pre-colli-
sion braking function or the pre-collision brake assist function was
operating)
The pre-collision system does not record conversations, sounds or
images of the inside of the vehicle.
● Data usage
Toyota may use the data recorded in this computer to diagnose
malfunctions, conduct research and development, and improve
quality.
Toyota will not disclose the recorded data to a third party except:
• With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
● Recorded images can be erased using a specialized device.
The image recording function can be disabled. However, if the func-
tion is disabled, data from when the pre-collision system operates
will not be available.

WARNING
■To avoid malfunction of the camera sensor
Observe the following precautions.
Otherwise, the camera sensor may not operate properly, possibly leading to
an accident resulting in death or serious injury.
● Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets,
snow, etc., clear the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces- sary to use the windshield wipers to remove water droplets, etc. from
the area of the windshield in front of the camera sensor.
• If the inner side of the windshield where the camera sensor is installed is dirty, contact your Toyota dealer.
● If the part of the windshield in front of the camera sensor is fogged up or
covered with condensation or ice, use the windshield defogger to remove
the fog, condensation or ice. ( P. 362)
● If water droplets cannot be properly removed from the area of the wind-
shield in front of the camera sensor by the windshield wipers, replace the
wiper insert or wiper blade.
• To replace the wiper insert: P. 4 4 7
• If the wiper blades need to be replaced, contact your Toyota dealer.
● Do not attach window tinting to the windshield.
● Replace the windshield if it is damaged or cracked.
If the windshield needs to be replaced, contact your Toyota dealer.
● Do not get the camera sensor wet.
● Do not allow bright lights to shine into the camera sensor.
●Do not attach objects, such as stickers,
transparent stickers, etc., and so forth,
to the outer side of the windshield in
front of the camera sensor (shaded
area in the illustration).
A: From the top of the windshield to
approximately 0.4 in. (1 cm) below the
bottom of the camera sensor
B: Approximately 7.9 in. (20 cm)
(Approximately 4.0 in. (10 cm) to the
right and left from the center of the
camera sensor)

PCS (Pre-Collision System)
◆Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian is high, a warning operates to
urge the driver to take evasive action and the potential brake
pressure is increased to help the driver avoid the collision. If the
system determines that the possibility of a frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically applied to help avoid the collision or help reduce the
impact of the collision.The pre-collision system can be disabled/enabled and the warning
timing can be changed. ( P. 209)
