*: If equipped
Various sensors are used to
obtain the necessary informa-
tion for system operation.
WARNING
●When using an automatic car
wash
●When a sensor is misaligned or
deformed due to a strong
impact being applied to the sen-
sor or the area around the sen-
sor
●When accessories which
obstruct a sensor or light are
temporarily installed to the vehi-
cle
●When a compact spare tire or
tire chains are installed to the
vehicle or an emergency tire
puncture repair kit has been
used
●When the tires are excessively
worn or the inflation pressure of
the tires is low
●When tires other than the manu-
facturer specified size are
installed
●When the vehicle cannot be
driven stably, due to a collision,
malfunction, etc.

Driving
■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.
■Pre-collision brake control
If the system determines that
the possibility of a collision is
extremely 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,
assistance will be provided to
help enhance vehicle stability
and prevent lane departure.
During assistance, in addition to
the pre-collision warning, the fol-
lowing icon will be displayed on
the multi-information display.
 The possibility of a collision is
high
 There is sufficient space
within the lane to perform
evasive steering maneuvers
 The driver is operating the steering wheel
Vehicles with active steering
function: The brakes and steer-
ing are controlled to help avoid a
collision or reduce the impact of
a collision, regardless of the
evasive steering maneuvers
performed by the driver.
During assistance, the pre-colli-
sion warning will operate and a
message will be displayed to
warn the driver.
■Intersection collision avoid-
ance support (left/right
turn)
In situations such as the follow-
ing, if the system determines
that the possibility of a collision
is high, the pre-collision warning
and pre-collision braking will
operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
 When turning left/right at an
intersection and crossing the
path of an oncoming vehicle

■Operating conditions of func-
tion
This function is operable when all of
the following conditions are met:
●The LTA system detects lane lines
or the path of preceding or sur-
rounding vehicles.
●The dynamic radar cruise control
is operating.
●The lane width is approximately
10 to 13 ft. (3 to 4 m).
●The turn signal lever is not being
operated.
●The vehicle is not being driven
around a sharp curve.
●The vehicle is not accelerating or
decelerating more than a certain
amount.
●The steering wheel is not being
turned with a large force.
●The hands off steering wheel
warning ( P.307) is not operat-
ing.
●The vehicle is being driven in the
center of a lane.
■Temporary cancelation of func-
tions
●When the operating conditions are
no longer met, a function may be
temporarily canceled. However,
when the operation conditions are
met again, operation of the func-
tion will automatically be restored.
(  P.307)
●If the operating conditions of a
function are no longer met while
the function is operating, a buzzer
may sound to indicate that the
function has been temporarily
canceled.
●The steering assist operation of
the function can be overridden by
the steering wheel operation of
the driver.
■Lane departure warning func-
tion when the LTA is operating
●Even if the LDA warning method is
changed to vibration of the steer-
ing wheel, if the vehicle deviates
from the lane while the LTA is
operating, the warning buzzer will
sound to alert the driver.
●If steering wheel operation equiv-
alent to that necessary for a lane
change is detected, the system
will determine the vehicle is not
deviating from the lane and the
warning will not operate.
■Hands off steering wheel warn-
ing operation
●When the system determines the
driver is not holding the steering
wheel, a message urging the
driver to grip the steering wheel
and the icon show n in the illustra-
tion will be displayed on the multi-
information display to warn the
driver. If the system detects that
the steering wheel is held, the
warning will be canceled. When
using the system, make sure to
grip the steering wheel firmly,
regardless of whether the warn-
ing is operating or not.
●If no operations are detected for a
certain amount of time, the warn-
ing will operate an d the function
will be temporarily canceled. This
warning may also operate if the
driver only operates steering
wheel a small amount continu-
ously.
■Situations in which the hands
off steering wheel warning may
not operate properly
●Depending on the condition of the

Driving
The LDA system warns the
driver if the vehicle may deviate
from the current lane or course
*,
and also can slightly operate the
steering wheel to help avoid
deviation from the lane or
course
*.
The front camera is used to
detect lane lines or a course
*.
*: Boundary between the asphalt and grass, soil, et c., or structures,
such as a curb, guardrail, etc.
■Lane departure alert func-
tion
When the system determines
that the vehicle might depart
from its lane or course
*, a warn-
ing is displayed on a display,
and either a warning buzzer will
sound or the steering wheel will
vibrate to alert the driver.
Check the area around your vehicle
and carefully operate the steering
wheel to move the vehicle back to
the center of the lane or course
*.
Vehicles with BSM: If the system
determines that the vehicle may
collide with a vehicle in an adjacent
lane, the lane de parture alert will
operate even if the turn signals are
operating.
*: Boundary between the asphalt and grass, soil, et c., or structures, such as a curb, guardrail, etc.
■Lane departure prevention
function
If the system determines that
the vehicle is likely to depart
from its lane or course
*, it pro-
vides assistance through steer-
ing wheel operations to help
avoid deviation from the lane or
course.
If the system determines that the
steering wheel has not been oper-
ated for a certain amount of time or
the steering wheel is not being
firmly gripped, a warning message
may be displayed and a warning
buzzer may sound to alert the
driver.
Vehicles with BSM: If the system
determines that the vehicle may
collide with a vehicle in an adjacent
lane, the lane departure prevention
function will operate even if the turn
signals are operating.
