WARNING
●If the brake pedal is being
depressed, the system may
determine that the driver is tak-
ing evasive 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 syste m 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 sys-
tem determines that lane depar-
ture prevention control has
completed.
●Depending on operations per-
formed by the driver, emer-
gency 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 signal lever is operated, the
system may determine that the
driver is taking evasive action
and the emergency steering
assist may not operate.
• While the emergency steering assist is operating, if the accel-
erator pedal is depressed
strongly, the st eering wheel is
turned heavily, or the brake
pedal is depressed, the system
may determine that the driver is
taking evasive action and emer-
gency steering assist operation
may be canceled.
• While the emergency steering assist is operating, if the steer-
ing wheel is held or turned in the
opposite direction of system
operation, emergency steering
assist operation will be can-
celed.

■Detection of detectable objects
Objects are detected based on their
size, shape, and move-
ment.Depending on the ambient
brightness, movement, posture and
direction of a det ectable object, it
may not be detected and the system
may not operate properly. The sys-
tem detects shapes, such as the fol-
lowing, as detectable objects.
■Situations in which the system
may operate even though the
possibility of a co llision is not
high
●In certain situations, such as the
following, the sys tem may deter-
mine that the possibility of a colli-
sion is high and operate:
• When passing a detectable object
• When changing lanes while over-
taking a detectable object • When suddenly approaching a
detectable object
• When approaching a detectable
object or other ob ject on the road-
side, such as guardrails, utility
poles, trees, walls, etc.
• When there is a d etectable object
or other object by the roadside at
the entrance of a curve
• When there are patterns or a painting ahead of the vehicle that
may be mistaken for a detectable
object
• When passing a detectable object that is changing lanes or turning
left/right

warning ( P.278) 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.277)
●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 aler
t 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
In the following si tuations, a mes-
sage urging the driver to grip the
steering wheel and the icon shown
in the illustration will be displayed on
the multi-information display to warn
the driver. If the system detects that
the steering wheel is held, the warn-
ing will be canceled. When using the
system, make sure to grip the steer-
ing wheel firmly, regardless of
whether the warning is operating or
not.
●When the system determines the
driver is not hold ing the steering
wheel while the function is operat-
ing
If no operations are detected for a
certain amount of time, a buzzer will
sound, the warning will operate, and
the function will be temporarily can-
celed. This warnin g may also oper-
ate if the driver only operates

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 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, 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 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

customize 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 func-
tion may not operate if the system
judges that the vehicle is inten-
tionally being ste ered to avoid a
pedestrian or parked vehicle.
●Vehicles with BSM: It may not be
possible for the sys tem 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.

■Hands off steering wheel warn-
ing operation
In the following si tuations, a mes-
sage 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 sys-
tem, make sure to grip the steering
wheel firmly, rega rdless of whether
the warning is operating or not.

 When the accelerator pedal is
depressed
When a curve is detected, the
vehicle speed will begin being
reduced. When the curve ends,
the vehicle speed reduction will
end.
Depending on the situation, the
vehicle speed will then return to the
set vehicle speed.
In situations where vehicle-to-vehi-
cle distance control needs to oper-
ate, such as whe n a preceding
vehicle cuts in front of your vehicle,
the curve speed r eduction function
will be canceled.
■Situations in which the curve
speed reduction function may
not operate
In situations such as the following,
the curve speed r eduction 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 your vehicle is being driven at
approximately 50 mph (80 km/h)
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 accel-
erate up to the set speed to
assist in overtaking.
The system’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-ha nd drive). If the
vehicle is driven in a location where
the passing lane i s 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 traf-
fic location, but is being driven in a
left-hand traffic location. The vehi-
cle may accelera te when the turn
signal lever is operated to the right.)
If your vehicle is being driven at
approximately 50 mph (80 km/h) or
more and the lane is changed to
that with a vehicle traveling slower
than your vehicle, when the turn
signal lever is operated the vehicle
will gradually decelerate to assist in
changing lanes.
