to the vehicle • When there is insufficient space to perform evasive steering maneuvers
or an obstruction exists in the evasion direction• When there is an oncoming vehicle
 The pre-collision system can be
enabled/disabled through a cus-
tomize setting. ( P.568)
The system is enabled each time the
power switch is turned to ON.
 When the system is disabled, the
PCS warning light will illuminate
and a message will be displayed
on the multi-information display.
“Pre-Collision System OFF”
 The pre-collision setting can be
changed on the customize set-
tings. ( P.568)
 When the pre-collision warning
timing is changed, the emer-
gency steering assist (excluding
the active steering function) tim-
ing will also be changed. When
“Later” is selected, the emer-
gency steering assist (excluding
the active steering function) will
not operate in most cases.
 Vehicles with a driver monitor
camera: When the system deter-
mines that the driver is not facing
forward, the pre-collision warning
and emergency steering assist
will operate at the “Earlier” tim-
ing, regardless of the user set-
ting.
 When the dynamic radar cruise
control is operating, the pre-colli-
sion warning will operate at the
“Earlier” timing, regardless of the
user setting.

5-4. Using the driving support systems
When driving on a road with
clear lane lines with the dynamic
radar cruise control operating,
lane lines and preceding and
surrounding vehicles are
detected using the front camera
and radar sensor, and the steer-
ing wheel is operated to maintain
the vehicle’s lane position.
Use the this function only on highways
and expressways.
If the dynamic radar cruise control is
not operating, the function will not oper-
ate.
In situations where the lane lines are
difficult to see or are not visible, such as
when in a traffic jam, support will be
provided using the path of preceding
and surrounding vehicles.
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, the
driver will be alerted via a display and
this function will be temporarily can-
celed.
If the steering wheel is firmly gripped,
the function will begin operating again.
 When the function is operating, if
the vehicle is likely to depart from
its lane, the driver will be alerted
via a display and buzzer.
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.

■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.

Dynamic radar cruise
control
This dynamic radar cruise con-
trol detects the presence of
vehicles ahead, determines the
current vehicle-to -vehicle dis-
tance, and operates to main-
tain a suitable distance from
the vehicle ahead. The desired
vehicle-to-vehicle distance can
be set by operating the vehi-
cle-to-vehicle distance switch.
Use the dynamic radar cruise
control only on highways and
expressways.
WARNING
■For safe use
●Driving safely is solely the responsi- bility of the driver. Do not overly rely
on this system, and pay careful attention to the surrounding condi-tions in order to ensure safe driving.
●The dynamic radar cruise control provides driving assistance to
reduce the driver’s burden. How- ever, there are limitations to the assistance provided. Read the fol-
lowing items carefully. Do not overly rely on this system and always drive carefully.
Conditions under which the system may not operate correctly: P.313
●Set the speed appropriately accord- ing to the speed limit, traffic flow,
road conditions, weather condi- tions, etc. The driver is responsible for confirming the set speed.

5-4. Using the driving support systems
WARNING
●Even if the system is operating cor- rectly, the condition of a preceding
vehicle as recognized by the driver and detected by the system may differ. Therefore, 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 acci- dent resulting in death or serious injury.
■Precautions for the driving assist systems
Observe the following precautions, as there are limitations to the assistance provided by the system. Over-reliance
on this system may lead to an acci- dent resulting in death or serious injury.
●Details of support provided for the driver’s vision The dynamic radar
cruise control is only intended to help the driver in determining the distance between the driver’s own
vehicle and a designated preceding vehicle. It is not a system which allows for careless or inattentive
driving, and is not a system which assists in poor visibility conditions. The driver must pay attention to
their surroundings, even when the vehicle stops.
●Details of support provided for the driver’s judgement The dynamic radar cruise control determines
whether the distance between the driver’s own vehicle and a desig-nated preceding vehicle is within a
set range. It is not capable of mak- ing any other type of judgement. Therefore, it is absolutely neces-
sary for the driver to remain vigilant and to determine whether or not there is a possibility of danger.
●Details of support provided for the driver’s operation The dynamic radar cruise control does not
include functions which will prevent or avoid collisions with vehicles ahead of your vehicle. Therefore, if
there is ever any possibility of dan- ger, the driver must take immediate and direct control of the vehicle and
act appropriately in order to ensure safety.
■Situations in which the dynamic radar cruise control should not be used
Do not use the dynamic radar cruise control in the following situations. As the system will not be able to provide
appropriate control, using it may lead to an accident resulting in death or serious injury.
●Roads where there are pedestrians, cyclists, etc.
●When driving on a highway or expressway entrance or exit
●When the approach warning sounds frequently
●Situations in which the sensors may not operate properly: P.279
●Situations in which the lane may not be detected: P. 2 8 1
