■Situations in which the system may
not operate properly
●In certain situations, such as the fol-
lowing, a detectable object may not be detected by the front sensors, and the system may not operate properly:
• When a detectable object is approaching your vehicle• When your vehicle or a detectable
object is wandering • When a detectable object makes an abrupt maneuver (such as sudden
swerving, acceleration or decelera- tion)• When suddenly approaching a detect-
able object • When the detectable object is near a wall, fence, guardrail, manhole cover,
steel plate on the road surface, or another vehicle• When there is a structure above a
detectable object • When part of a detectable object is hidden by another object (large lug-
gage, umbrella, guardrail, etc.) • When multiple detectable objects are overlapping
• When a bright light, such as the sun, is reflecting off of a detectable object• When a detectable object is white and
looks extremely bright • When the color or brightness of a detectable object causes it to blend in
with its surroundings • When a detectable object cuts in front of or suddenly emerges in front of
your vehicle • When approaching a vehicle which is diagonal
• If a vehicle ahead is a child sized bicy- cle, is carrying a large load, is carrying an extra passenger, or has an unusual
shape (bicycles equipped with a child seat, tandem bicycles, etc.)• If a pedestrian or bicycle is shorter
than approximately 1 m (3.2 ft.) or taller than approximately 2 m (6.5 ft.).• When the silhouette of a pedestrian or
bicycle is unclear (such as when they are wearing a raincoat, long skirt, etc.)• When a pedestrian or bicycle is bend-
ing forward or squatting
• When a pedestrian or bicycle is mov- ing at high speed• When a pedestrian is pushing a
stroller, wheelchair, bicycle or other vehicle• When a detectable object blends in
with the surrounding area, such as when it is dim (at dawn or dusk) or dark (at night or in a tunnel)
• When the vehicle has not been driven for a certain amount of time after the EV system was started
• While turning left/right or a few sec- onds after turning left/right• While driving around a curve and a
few seconds after driving around a curve• When turning left/right and an oncom-
ing vehicle is driving in a lane 3 or more lanes from the vehicle• When turning left/right and the direc-
tion of the vehicle differs greatly from the direction traffic flows in the oncoming lane
• When turning left/right and approach- ing a pedestrian which was traveling
in the same direction as the vehicle and continues straight
●In addition to the preceding, in certain situations, such as the following, the emergency steering assist may not
operate properly:

 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.

detected, the system will determine
the vehicle is not deviating from the lane and the warning will not operate.
■Hands off steering wheel warning operation
In the following situations, a message urging the driver to grip the steering wheel and the icon shown in the illustra-
tion will be displayed on the multi-infor- mation display to warn the driver. If the system detects that the steering wheel
is held, the warning will be canceled. When using the system, make sure to grip the steering wheel firmly, regardless
of whether the warning is operating or not.
●When the system determines the driver is not holding the steering wheel while the function is operating
If no operations are detected for a cer- tain amount of time, a buzzer will sound, the warning will operate, and the func-
tion will be temporarily canceled. This warning may also operate if the driver only operates steering wheel a small
amount continuously.
Depending on the condition of the vehi- cle, handle control condition and road
surface, the warning function may not operate.
The LTA will change between
enabled/disabled each time the LTA
switch is pressed.
When the LTA is enabled, the LTA indi-
cator will illuminate.
