■Operating conditions of function
This function is operable when all of the following conditions are met:
●The LTA system detects lane lines or
the path of preceding or surrounding
vehicles (except when the preceding vehicle is small, such as a motorcy-cle).
●The dynamic radar cruise control is operating.
●The lane width is approximately 3 to 4 m (10 to 13 ft.).
●The turn signal lever is not being oper-ated.
●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.296) is not operating.
●The vehicle is being driven in the
center of a lane.
■Temporary cancelation of functions
●When the operating conditions are no
longer met, a function may be tempo- rarily canceled. However, when the operation conditions are met again,
operation of the function will automati- cally be restored. ( P.295)
●If the operating conditions of a func- tion are no longer met while the func-tion 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 function
when the LTA is operating
●Even if the LDA warning method is
changed to vibration of the steering 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 equivalent to that necessary for a lane change is
WARNING
■Before using the LTA system
●Do not overly rely on the LTA sys-tem. The LTA system is not a sys-
tem which provides automated assistance in driving and it is not a system which reduces the amount
of attention necessary for safe driv- ing. The driver is solely responsible for paying attention to their sur-
roundings and operating the steer- ing wheel as necessary to ensure safety. Also, the driver is responsi-
ble for taking adequate breaks when fatigued, such as when driv-ing for a long time.
●Failure to perform appropriate driv-ing operations and pay careful
attention may lead to an accident.
●When not using the LTA system,
turn it off using the LTA switch.

detected, the system will determine
the vehicle is not deviating from the lane and the warning will not operate.
■Hands off steering wheel warning operation
In the following situations, a message urging the driver to grip the steering wheel and the icon shown in the illustra-
tion will be displayed on the multi-infor- mation 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 warning is operating or not.
●When the system determines the driver is not holding the steering wheel while the function is operating
If no operations are detected for a cer- tain amount of time, a buzzer will sound, the warning will operate, and the func-
tion will be temporarily canceled. This warning may also operate if the driver only operates steering wheel a small
amount continuously.
Depending on the condition of the vehi- cle, handle control condition and road
surface, the warning function may not operate.
The LTA will change between
enabled/disabled each time the LTA
switch is pressed.
When the LTA is enabled, the LTA indi-
cator will illuminate.

tem
WARNING
■Situations in which the func- tions may not operate properly
In the following situations, the func- tions may not operate properly and the vehicle may depart from its lane.
Do not overly rely on these functions. The driver is solely responsible for paying attention to their surroundings
and operating the steering wheel as necessary to ensure safety.
●When a preceding or surrounding vehicle changes lanes (Your vehicle may follow the preceding or sur-
rounding vehicle and also change lanes)
●When a preceding or surrounding vehicle is swaying (Your vehicle may sway accordingly and depart
from the lane)

WARNING
●When a preceding or surrounding vehicle departs from a lane (Your
vehicle may follow the preceding or surrounding vehicle and also depart from the lane)
●When a preceding or surrounding vehicle is being driven extremely
close to the left/right lane line (Your vehicle may follow the preceding or surrounding vehicle accordingly
and depart from the lane)
●When there are moving objects or
structures in the surrounding area (Depending on the position of the moving object or structure relative
to your vehicle, your vehicle may sway)
●When the vehicle is struck by a crosswind or the turbulence of other nearby vehicles

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, etc., or structures, such
as a curb, guardrail, etc.
■Lane departure alert function
When the system determines that
the vehicle might depart from its
lane or course*, a warning is dis-
played 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*.
If the system determines that the vehi-
cle may collide with a vehicle in an
adjacent lane, the lane departure alert
will operate even if the turn signals are
operating.
*: Boundary between the asphalt and
grass, soil, etc., 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 provides assis-
tance through steering wheel oper-
ations to help avoid deviation from
the lane or course.
If the system determines that the steer-
ing wheel has not been operated 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.
If the system determines that the vehi-
cle may collide with a vehicle in an
adjacent lane, the lane departure pre-
vention function will operate even if the
turn signals are operating.
*: Boundary between the asphalt and
grass, soil, etc., or structures, such
as a curb, guardrail, etc.

●Break suggestion function
This function is operable when all of the
following conditions are met:
• The vehicle speed is approximately 50 km/h (32 mph) or more.• The lane width is approximately 3 m
(9.8 ft.) or more.
■Temporary cancelation of functions
When the operating conditions are no longer met, a function may be temporar-

restored. ( P.300)
■Operation of the lane departure alert function/lane departure pre-vention function
●Depending on the vehicle speed, road conditions, lane departure angle, etc.,
operation of the lane departure pre- vention function may not be felt or the function may not operate.
●Depending on the conditions, the warning buzzer may operate even if
vibration is selected through a cus- tomize setting.
●If a course* is not clear or straight, the
lane departure alert function or lane
departure prevention function may not operate.
●The lane departure alert function or lane departure prevention function may not operate if the system judges
that the vehicle is intentionally being steered to avoid a pedestrian or parked vehicle.
●It may not be possible for the system to judge if there is danger of a collision
with a vehicle in an adjacent lane.
●The steering assist operation of the
lane departure prevention function can be overridden by the steering
wheel operation of the driver.*: Boundary between the asphalt and
grass, soil, etc., or structures, such as
a curb, guardrail, etc.
■Hands off steering wheel warning
operation
In the following situations, a message urging the driver to operate the steering
wheel and an icon will be displayed and a buzzer will sound to warn the driver. When using the system, make sure to
grip the steering wheel firmly, regardless of whether the warning is operating or not.
●When the system determines that the driver is not securely holding the
steering wheel, or the steering wheel is not being operated when the steer-ing assist operation of the lane depar-
ture prevention function is operating
The length of time that the warning buzzer operates will become longer as
the frequency of the steering assist operating increases. Even if the system judges that the steering wheel has been
operated, the warning buzzer will sound for a certain amount of time.
