When the function is operat-
ing, if the vehicl e is likely to
depart from its lane, the driver

WARNING
■Before using the LTA system
●Do not overly rely on the LTA
system. The LTA system is not a
system which provides auto-
mated assistance in driving and
it is not a system which reduces
the amount of attention neces-
sary for safe drivi ng. 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
driving operations and pay care-
ful attention may lead to an
accident.
●When not using the LTA system,
turn it off using the LTA switch.

1794-5. Using the driving support systems

Driving
the following conditions are met:
●The LTA system detects lane lines
or the path of preceding or sur-
rounding vehicles (except when
the preceding vehicle is small,
such as a motorcycle).
●The dynamic radar cruise control
is operating.
●The lane width is approximately
10 to 13 ft. (3 to 4 m).
●The turn signal le ver 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.179) 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.178)
●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
steering wheel a small amount con-
tinuously.
Depending on the condition of the
vehicle, handle control condition
and road surface, t he warning func-
tion may not operate.

1804-5. Using the driving support systems
The LTA will change between
enabled/disabled each time the
LTA switch is pressed.
When the LTA is enabled, the LTA
indicator will illuminate.

WARNING
■Situations in which the func-
tions may not operate prop-
erly
In the following situations, the
functions may not operate prop-
erly 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 surround-
ing vehicle changes lanes (Your
vehicle may follow the preced-
ing or surrounding vehicle and
also change lanes)
●When a preceding or surround-
ing vehicle is swaying (Your
vehicle may sway accordingly
and depart from the lane)
●When a preceding or surround-
ing vehicle departs from a lane
(Your vehicle may follow the
preceding or surrounding vehi-
cle and also depart from the
lane)
●When a preceding or surround-
ing vehicle is being driven
extremely close to the left/right
lane line (Your vehicle may fol-
low the preceding or surround-
ing 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
●Situations in which the sensors
may not operate properly:

PDA (Proactive driv-
ing assist)
When a detectable object
(P.188) is detected, the
proactive driving assist
operates the brakes and
steering wheel to help pre-
vent the vehicle from
approaching too close to
the object.
WARNING
■For safe use
Driving safely is solely the respon-
sibility of the driver.
●The proactive driving assist is
designed to provide some
assistance for regular braking
and steering operations, as well
as helping to prevent the vehicle
from approaching too close to a
detectable object. However, the
scope of this assistance is lim-
ited.
The driver should perform brake
and steering operations as neces-
sary. Read the following items
carefully. Do not overly rely on the
proactive driving assist and
always drive carefully.( P.189)
●The proactive driving assist is
not a system which reduces the
amount of attention necessary
for safe driving. Even if the sys-
tem is operating correctly, the
surrounding conditions as rec-
ognized by the driver and
detected by the system may dif-
fer. It is necessary for the driver
to pay attention, assess risks,
and ensure safety. Over-reli-
ance on this system to drive the
vehicle safely may lead to an
accident resulting in death or
serious injury.
●Proactive driving assist is not a
system which allows for inatten-
tive driving and is not a system
which assists in poor visibility
conditions. The driver is solely
responsible for paying attention
to their surroundings and driving
safely.

ing assist off
