■High beam automatic turning on or off conditions
●When all of the following conditions are fulfilled, the high beam will be auto-
matically turned on (after approximately 1 second):
• Vehicle speed is above approximately 21 mph (34 km/h).
• The area ahead of the vehicle is dark.
• There are no vehicles ahead with headlights or tail lights turned on.
• There are few streetlights on the road ahead.
● If any of the following conditions are fulfilled, the high beam will be automat-
ically turned off:
• Vehicle speed drops below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have headlights or tail lights turned on.
• There are many streetlights on the road ahead.
■ Camera sensor detection information
●The high beam may not be automatically turned off in the following situa-
tions:
• When oncoming vehicles suddenly appear from a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead are hidden from sight due to repeated curves, road
dividers or roadside trees
• When vehicles ahead appear from the faraway lane on wide road
• When vehicles ahead vehicles have no lights
● The high beam may be turned off if a vehicle ahead that is using fog lights
without using the headlights is detected.
● House lights, street lights, traffic signals, and illuminated billboards or signs
may cause the high beam to switch to the low beams, or the low beams to
remain on.
● The following factors may affect the amount of time taken to turn the high
beam on or off:
• The brightness of headlights, fog lights, and tail lights of vehicles ahead
• The movement and direction of vehicles ahead
• When a vehicle ahead only has operational lights on one side
• When a vehicle ahead is a two-wheeled vehicle
• The condition of the road (gradient, curve, condition of the road surface
etc.)

4-3. Operating the lights and wipers
■The windshield wipers and washer can be operated when
The power switch is in ON mode.
■ Dripping prevention wiper sweep (vehicles with rain-sensing windshield
wipers)
After washing and wiping operation several times, the wipers operate one
more time after a short delay to prevent dripping. However, this function will
not operate while driving.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Vehicle speed affects the Intermittent wiper interval.
■ Raindrop sensor (vehicles with ra in-sensing windshield wipers)
● If the wiper switch is turned to the “AUTO” position while the power switch is
in ON mode, the wipers will operate once to show that AUTO mode is acti-
vated.
● If the wiper sensitivity is adjusted to higher, the wiper may operate once to
indicate the change of sensitivity.
● If the temperature of the raindrop sensor is 185 F (85 C) or higher, or 14 F
(-10 C) or lower, automatic operation may not occur. In this case, operate
the wipers in any mode other than AUTO mode.
■ If no windshield washer fluid sprays
Check that the washer nozzles are not blocked, if there is washer fluid in the
washer fluid tank.
■ Customization
Settings of AUTO mode operation can be changed.
(Customizable features: P. 757)
●
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.

WARNING
●Do not dirty or damage the camera sensor.
When cleaning the inside of the windshield, do not allow glass cleaner to
contact the lens. Also, do not touch the lens.
If the lens is dirty or damaged, contact your Toyota dealer.
● Do not subject the camera sensor to a strong impact.
● Do not change the installation position or direction of the camera sensor or
remove it.
● Do not disassemble the camera sensor.
● Do not install an electronic device or device that emits strong electric
waves near the camera sensor.
● Do not modify any components of the vehicle around the camera sensor
(inside rear view mirror, etc.) or ceiling.
● Do not attach any accessories that may obstruct the camera sensor to the
hood, front grille or front bumper. Contact your Toyota dealer for details.

WARNING
■Limitations of the pre-collision system
●The driver is solely responsible for safe driving. Always drive safely, taking
care to observe your surroundings.
Do not use the pre-collision system instead of normal braking operations
under any circumstances. This system will not prevent collisions or lessen
collision damage or injury in every situation. Do not overly rely on this sys-
tem. Failure to do so may lead to an accident, resulting in death or serious
injury.
● Although this system is designed to help avoid a collision or help reduce
the impact of the collision, its effectiveness may change according to vari-
ous conditions, therefore the system may not always be able to achieve
the same level of performance.
Read the following conditions carefully. Do not overly rely on this system
and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 283
• Conditions under which the system may not operate properly: P. 285
● Do not attempt to test the operation of the pre-collision system yourself, as
the system may not operate properly, possibly leading to an accident.
■ Pre-collision braking
●The pre-collision braking function may not operate if certain operations are
performed by the driver. If the accelerator pedal is being depressed
strongly or the steering wheel is being turned, the system may determine
that the driver is taking evasive action and possibly prevent the pre-colli-
sion braking function from operating.
● In some situations, while the pre-collision braking function is operating,
operation of the function may be canceled if the accelerator pedal is
depressed strongly or the steering wheel is turned and the system deter-
mines that the driver is taking evasive action.
● A large amount of braking force is applied while the pre-collision braking
function is operating. As the pre-collision braking function will be canceled
after the vehicle has been stopped for approximately 2 seconds, the driver
should depress the brake pedal as necessary.
● If the brake pedal is being depressed, the system may determine that the
driver is taking evasive action and possibly delay the operation timing of
the pre-collision braking function.
