LTA functions  
When driving on a road with  
clear lane lines with the  
dynamic radar cruise control  
operating, lane lines and pre-  
ceding and surrounding vehi-  
cles are detected using the  
front camera and radar sen-  
sor, and the steering wheel is  
operated to maintain the vehi-  
cle’s lane position.  
When "Later" is selected, the  
emergency steering assist  
(excluding the active steering  
function) will not operate in  
most cases.  
When the dynamic radar  
cruise control is operating, the

operate at the “Earlier” timing,  
regardless of the user setting.  
If the dynamic radar cruise control  
is not operating, the function will not  
operate.  
In situations where the lane lines  
are difficult to see or are not visible,  
such as when in a traffic jam, sup-  
port will be provided using the path  
of preceding and surrounding vehi-  
cles.  
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, the driver will be  
alerted via a display and this func-  
tion will be temporarily canceled.  
If the steering wheel is firmly  
gripped, the function will begin  
operating again.

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 driving. The driver  
is solely responsible for paying  
attention to their surroundings  
and operating the steering  
When the buzzer sounds, check  
the area around the vehicle and  
carefully operate the steering wheel  
to move the vehicle back to the  
center of the lane.  
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.  
Operating conditions of func-  
tion

4-5. Using the driving support systems  
the following conditions are met: from the lane while the LTA is  
operating, the warning buzzer will  
sound to alert the driver.  
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).  
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.  
The dynamic radar cruise control

operated.  
In the following situations, a mes-  
sage urging the driver to grip the  
steering wheel and the icon shown

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.  
The vehicle is not being driven  
around a sharp curve.  
The vehicle is not accelerating or

Temporary cancelation of func-

met again, operation of the func-  
tion will automatically be restored.  
(P.202)  
When the system determines the  
driver is not holding the steering  
wheel while the function is operat-  
ing  
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.  
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 warning may also oper-  
ate if the driver only operates  
steering wheel a small amount con-  
tinuously.  
The steering assist operation of  
the function can be overridden by  
the steering wheel operation of  
the driver.  
Depending on the condition of the  
vehicle, handle control condition  
and road surface, the warning func-  
tion may not operate.
