Beam indicator will illuminate.
■Conditions to turn the high
beams on/off automatically
●When all of the following condi-
tions are met, the high beams will
be turned on automatically (after
approximately 1 second):
• The vehicle speed is approxi- mately 21 mph (34 km/h) or more.
• 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 met, the high beams will turn
off automatically:
• The vehicle speed is below approximately 17 mph (27 km/h).
• The area ahead of the vehicle is not dark.
• Vehicles ahead have their head- lights or tail lights turned on.
• There are many streetlights on the road ahead.
■Camera sensor detection infor-
mation
●The high beams may not be auto-
matically turned of f in the following situations:
• When a vehicle suddenly appears from around a curve
• When the vehicle is cut in front of by another vehicle
• When vehicles ahead cannot be
detected due to repeated curves,
road dividers or roadside trees
• When vehicles ahead appear in a
faraway lane on a wide road
• When the lights of vehicles ahead are not on
●The high beams may be turned off
if a vehicle ahead that is using fog
lights without its headlights turned
on is detected.
●House lights, stre etlights, traffic
signals, and illuminated billboards
or signs and other reflective
objects may cause the high
beams to change to the low
beams, or the low beams to
remain on.
●The following factors may affect
the amount of time taken for the
high beams to turn on or off:
• The brightness of the headlights,
fog lights, and tail lights of vehi-
cles 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 (gradi-
ent, curve, condition of the road
surface, etc.)
• The number of passengers and
amount of luggage in the vehicle
●The high beams may turn on or off
unexpectedly.
●Bicycles or similar vehicles may
not be detected.
●In the following situations the sys-
tem may not be able to correctly
detect the surrounding brightness
level. This may cause the low
beams to remain on or the high
beams to flash or dazzle pedestri-
ans or vehicles ahead. In such a
case, it is necessary to manually

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in
the system.
●In the following situations, perform the actions specified in the table. When
the normal operating cond itions are detected, the message will disappear
and the system will be come operational.
If the message does not disappear, contact your Toyota dealer.
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the sy stem will become opera-
tional.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter. ( P.411, 419).
When the temperature around the
front camera is outside of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker,
etc. to clear the obstruction.
When “Pre-Collision System
Unavailable” is displayed.
Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

1944-5. Using the driving support systems
If the message does not disappear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-tional range, such as when the vehicle is in the sun or in an extremely cold
environment
• When the front camera cannot detect objects in front of the vehicle, such as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera
• Depending on the conditions in the vicinity of the vehicle, the radar may judge the surrounding environment can not be properly recognized. In that
case, “Pre-Collision System Unavailable” is displayed.

The system can detect the fol-
lowing:
Vehicles
 Bicyclists
 Pedestrians
■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.
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.198) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object 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 possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. ( P.197)
Detectable objects

trical noise may be present
■Situations in which the system
may not operate properly
●In some situations such as the fol-
lowing, an object may not be
detected by the radar sensor and
front camera, preventing the sys-
tem from operating properly:
• When a detectable object is approaching your vehicle
• When your vehicle or a detectable object is wobbling
• If a detectable object makes an abrupt maneuver (such as sudden

2024-5. Using the driving support systems
• When driving through steam or smoke
• When the surrounding area is dim,
such as at dawn or dusk, or while
at night or in a tunnel, making a
detectable object appear to be
nearly the same color as its sur-
roundings
• When driving in a place where the
surrounding brightness changes
suddenly, such as at the entrance
or exit of a tunnel
• After the engine has started the vehicle has not been driven for a
certain amount of time
• While making a left/right turn and for a few seconds after making a
left/right turn
• While driving on a curve and for a few seconds after driving on a
curve
• If your vehicle is skidding
• If the front of the vehicle is raised or lowered
• If the wheels are misaligned
• If a wiper blade is blocking the front camera
• The vehicle is being driven at extremely high speeds
• When driving on a hill
• If the radar sensor or front camera is misaligned
●In some situations such as the fol-
lowing, sufficient braking force
may not be obtained, preventing
the system from performing prop-
erly:
• If the braking functions cannot operate to their full extent, such as
when the brake parts are
extremely cold, extremely hot, or
wet
• If the vehicle is not properly main- tained (brakes or tires are exces- sively worn, improper tire inflation
pressure, etc.)
• When the vehicle is being driven
on a gravel road or other slippery
surface

■Hands off steering wheel warn-
ing
In the following si tuations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illustration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the system determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardle ss of warnings.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
system is operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned
and the function is temporarily can-
celed. This warning also operates in
the same way when the driver con-
tinuously operates the steering
wheel only a small amount.
●When the system determines that
the vehicle may deviate from the
lane while driving around a curve
while the lane centering function is
operating.
Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curve, warnings will
occur earlier than during
straight-lane driving.
●When the system determines that
the driver is driving without hold-
ing the steering wheel while the
steering wheel assist of the steer-
ing assist function is operating. If the driver continues to keep their
hands off of the steering wheel and
the steering wheel assist is operat-
ing, the buzzer sounds and the
driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
■Vehicle sway warning function
