●When the driver’s eyes are blocked by
the frame of eyeglasses, sunglasses, hair, etc.
●When there is a device inside the vehicle that radiates near infrared rays, such as a non-genuine driver
monitoring system.
■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.

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.

The system can detect the follow-
ing as detectable objects. (Detect-
able objects differ depending on the
function.)
 Vehicles
 Bicycles*
Pedestrians
 Motorcycles*
*: 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.

■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.

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.

■Operating conditions of each function of the pre-collision system
The pre-collision system is enabled and the system determines t hat the possibility of a frontal collision with a detected object is high.
However, the system will not operate in the following situation s:
●When the vehicle has not been driven a certain amount after a terminal of the 12-
volt battery has been disconnected and reconnected
●When the shift position is in R
●When the VSC OFF indicator is illuminated (only the pre-collisi on warning function will be operational)

■Detection of detectable objects
Objects are detected based on their size, shape, and movement.Depending
on the ambient brightness, movement, posture and direction of a detectable object, it may not be detected and the
system may not operate properly. The system detects shapes, such as the fol-lowing, as detectable objects.
