WARNING
■Front camera installation area on the windshield
If the system determines that the windshield may be fogged up, it will automatically operate the heater to
defog the part of the windshield around the front camera. When clean-ing, etc., be careful not to touch the
area around the front camera until the windshield has cooled sufficiently, as touching it may cause burns.
■Precautions for the driver moni-tor camera (if equipped)
Observe the following precautions. Failure to do so may lead to malfunc-tion of the driver monitor camera and
the systems not operating properly, possibly leading to an accident result-ing in death or serious injury.
●Do not subject the driver monitor camera or its surrounding area to
strong impact.
If subjected to a strong impact, the
driver monitor camera may move out
of alignment and the driver may no
longer be detected correctly. In this
case, have the vehicle inspected by
any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
●Do not disassemble or modify the driver monitor camera.
●Do not attach accessories, stickers (including transparent stickers), etc. to the driver monitor camera or its
surrounding area.
●Do not allow the driver monitor
camera or its surrounding area to get wet.
●Do not cover the driver monitor camera or place anything in front of it.
●Keep the lens of the driver monitor camera free from damage.
●Do not touch the lens of the driver monitor camera or allow it to become dirty.
When there is dirt or fingerprints on
the camera lens, clean it with a dry,
soft cloth so as to not mark or dam-
age it.
●When cleaning the lens, do not use
detergents or organic solvents that may damage plastic.

■Certification
P. 6 3 5
*: If equipped
During controlled driving, the driver
monitor camera detects the position
and direction the driver is facing,
and whether their eyes are opened
or closed. Through this, the system
determines if the driver is checking
their surroundings and if the driver
can perform driving operations.
■Warning function
In situations such as the following,
a buzzer will sound and a message
will be displayed to warn the driver.
When the system determines that
the driver is not paying attention to
the road or their eyes are closed.
When the driver’s face cannot be
detected or the system determines
that the driver has poor driving pos-
ture.

tion, driver monitor system is a

WARNING
■For safe use
●The driver monitor is not designed to prevent the driver from driving carelessly or having a poor driving
posture. Pay careful attention to the sur-rounding conditions in order to
ensure safe driving.
●The driver monitor cannot reduce
drowsiness. If you feel unable to concentrate or drowsy, take a break and sleep as necessary in order to
ensure safe driving.

PCS (Pre-Collision Sys-
tem)
The pre-collision system uses
sensors to detect objects
( P.284) in the path of the
vehicle. When the system
determines that the possibility
of a frontal collision with a
detectable obj ect is high, a
warning operates to urge the
driver to take evasive action
and the potential brake pres-
sure is increased to help the
driver avoid the collision. If the
system determines that the
possibility of a collision is
extremely high, the brakes are
automatically applied to help
avoid the collision or help
reduce the impact of the colli-
sion.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.
( P.293)
WARNING
■For safe use
●Driving safely is solely the responsi-
bility of the driver. Pay careful atten- tion to the surrounding conditions in order to ensure safe driving. Never
use the pre-collision system in place of normal braking operations. This system cannot help avoid or
reduce the impact of a collision in every situation. Over-reliance on this system to drive the vehicle
safely may lead to an accident resulting in death or serious injury.

able objects differ depending on the
function.)

*: Detected as a detectable object only
when being ridden.
■Pre-collision warning
When the system determines that
the possibility of a collision is high,
a buzzer will sound and an icon and
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
If the detectable object is a vehicle,
moderate braking will be performed
with the warning.
“Pre-Collision System”
If the system determines that the
accelerator pedal is strongly
depressed, the following icon and
message will be displayed on the
multi-information display.
“Accelerator Pedal is Pressed”
■Pre-collision brake assist
If the system determines that the
possibility of a collision is high and
the brake operation by the driver is
insufficient, the braking power will
be increased.

WARNING
●Although the pre-collision system is designed to help avoid or help
reduce the impact of a collision, its effectiveness may change accord-ing to various conditions. Therefore,
it may not always be able to achieve the same level of perfor-mance. Read the following items
carefully. Do not overly rely on this system and always drive carefully.

high, the brakes are automatically
applied to help avoid the collision or
reduce the impact of the collision.
■Emergency steering assist
If the system determines that the
following conditions are met, assis-
tance will be provided to help
enhance vehicle stability and pre-
vent lane departure. During assis-
tance, in addition to the pre-
collision warning, the following icon
will be displayed on the multi-infor-
mation display.

There is sufficient space within
the lane to perform evasive
steering maneuvers
The driver is operating the steer-
ing wheel
During assistance, the pre-collision
warning will operate and a mes-
sage will be displayed to warn the
driver.
■Intersection collision avoid-
ance support (left/right turn)
In situations such as the following,
if the system determines that the
possibility of a collision is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.
When turning left/right at an
intersection and crossing the
path of an oncoming vehicle
When turning left/right and an
oncoming pedestrian or bicycle
is detected
■Intersection collision avoid-
ance support (crossing vehi-
cles)
At an intersection, etc., if the sys-
tem determines that the possibility
of a collision with an approaching
vehicle or motorcycle is high, the
pre-collision warning and pre-colli-
sion braking will operate. Depend-
ing on the intersection, assistance
may not operate correctly.

■Acceleration Suppression at
Low Speed
When driving at a low speed, if the
accelerator pedal is strongly
depressed and the system deter-
mines that there is a possibility of a
collision, EV system output will be
restrained or the brakes will be
applied weakly to restrict accelera-
tion. During operation, a buzzer will
sound and a warning indicator and
message will be displayed on the
multi-information display.
“Accelerator Pedal is Pressed”
WARNING
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force will be
applied.
●Pre-collision braking function is not intended for remain stopped. If the vehicle is stopped by pre-collision
braking function, the driver should operate the brakes as necessary.
●The pre-collision braking function may not operate if certain opera-tions 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 tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision brake control.
■Acceleration Suppression at Low Speed
If the steering wheel is being turned,
the system may determine that the driver is taking evasive action and possibly prevent the Acceleration
Suppression at Low Speed function from operating.
■Emergency steering assist
●The emergency steering assist will be canceled when the system
determines that lane departure pre- vention control has completed.
●Depending on operations per-formed by the driver, emergency steering assist may not operate or
operation may be canceled.
• If the accelerator pedal is
depressed strongly, the steering wheel is turned heavily, the brake pedal is depressed, or the turn sig-
nal lever is operated, the system may determine that the driver is tak-ing evasive action and the emer-
gency steering assist may not operate.
