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

WARNING
■Before using the LDA system
●Do not overly rely on the LDA sys-
tem. The LDA system is a system which provides automated assis-tance in driving. However, as it is
not a system which reduces the amount of attention necessary for safe driving. The driver is solely
responsible for paying attention to their surroundings and operating the steering wheel as necessary to
ensure safety. Also, the driver is responsible for taking adequate breaks when fatigued, such as
when driving for a long time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident.

■Situations in which the curve speed reduction function may not operate
In situations such as the following, the curve speed reduction function may not operate:
●When the vehicle is being driven around a gentle curve
●When the accelerator pedal is being depressed
●When the vehicle is being driven around an extremely short curve
If a detected vehicle in the passing
lane is traveling slower than your
vehicle, overtaking will be sup-
pressed.
The overtaking prevention function will
not operate if the passing lane is con-
gested or vehicles are traveling at low
speeds.
This function is not available for vehi-
cles without a DCM.
If your vehicle is being driven at
approximately 80 km/h (50 mph) or
more and a lane change to the
passing lane is performed, when
the turn signal lever is operated and
the lane is changed, the vehicle will
accelerate up to the set speed to
assist in overtaking.
For vehicles with a DCM: The system’s
recognition of which lane is the passing
lane is determined by location informa-
tion and the driving condition of sur-
rounding vehicles. The support for lane
change function and overtaking preven-
tion function may not operate if it is diffi-
cult to obtain location information or
there are few surrounding vehicles.
For vehicles without a DCM: The sys-
tem’s recognition of which lane is the
passing lane may be based solely on
the location of the steering wheel in the
vehicle (left-hand drive/right-hand
drive). If the vehicle is driven in a loca-
tion where the passing lane is on the
opposite side of that where the vehicle
was originally sold, the vehicle may
accelerate when the turn signal lever is
operated away from the passing lane.
(e.g. The vehicle was manufactured for
a right-hand traffic location, but is being
driven in a left-hand traffic location. The
vehicle may accelerate when the turn
signal lever is operated to the right.)
If your vehicle is being driven at approx-
imately 80 km/h (50 mph) or more and
the lane is changed to that with a vehi-
cle traveling slower than your vehicle,
when the turn signal lever is operated
the vehicle will gradually decelerate to
assist in changing lanes.

In the following situations, the set speed
may not change to the detected speed limit by pressing and holding the “+” switch or “-” switch:
●When the detected speed limit is the same as the set speed
●When the detected speed limit is out-side of the speed range which the
speed limiter system can operate
Emergency Driving Stop
System
The emergency driving stop
system is a system which
automatically decelerates and
stops the vehicle within its
lane if the driver becomes
unable to continue driving the
vehicle, such as if they have
suffered a medical emergency,
etc.
During LTA (Lane Tracing
Assist) control, if the system
does not detect driving opera-
tions, such as if the driver is
not holding the steering wheel,
and determines the driver is
not responsive, the vehicle will
be decelerated and stopped
within its current lane to help
avoid a collision or reduce the
impact of a collision.
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. The
emergency driving stop system is designed to provide support in an emergency where it is difficult for
the driver to continue driving, such as if they have had a medical emer-gency. It is not designed to support
driving while drowsy or in poor physical health, or inattentive driv-ing.
