WARNING
●Although this system is designed to he l p a vo id a c ol li s io n o r he lp r ed u ce
the impact of the collision, its effec- tiveness may change according to various conditions, therefore the
system may not always be able to achieve the same level of perfor-mance.
Read the following conditions care- fully. Do not overly rely on this sys-tem and always drive carefully.
• Conditions under which the system may operate even if there is no pos-
sibility of a collision: P. 1 6 7
• Conditions under which the system
may not operate properly: P. 1 6 9
●Do not attempt to test the operation
of the pre-collision system yourself. Depending on the objects used for testing (dummies, cardboard
objects imitating detectable objects, etc.), the system may not operate properly, possibly leading to an
accident.
■Pre-collision braking
●When the pre-collision braking function is operating, a large amount of braking force will be
applied.
●If the vehicle is stopped by the
operation of the pre-collision brak- ing function, the pre-collision brak-ing function operation will be
canceled after approximately 2 sec- onds. Depress the brake pedal as necessary.
●The pre-collision braking function may not operate if certain opera-tions are performed by the driver. If
the accelerator pedal is being depressed strongly or the steering wheel is being turned, the system
may determine that the driver is tak- ing evasive action and possibly pre-vent the pre-collision braking
function from operating.
●In some situations, while the pre-
collision braking function is operat- ing, operation of the function may be canceled if the accelerator pedal
is depressed strongly or the steer- ing wheel is turned and the system determines that the driver is taking
evasive action.
●If the brake pedal is being
depressed, the system may deter- mine that the driver is taking eva-sive action and possibly delay the
operation timing of the pre-collision braking function.
■Emergency steering assist
●As emergency steering assist oper-ation will be canceled when the sys-
tem determines that lane departure prevention function has been com-pleted.
●Emergency steering assist may not operate or may be cancel in the fol-
lowing cases as the system may determine the driver is taking actions.
• If the accelerator pedal is being depressed strongly, the steering
wheel is being operated sharply, the brake pedal is being depressed or the turn signal lever is being
operated. In this case, the system may determine that the driver is tak-ing evasive action and the emer-
gency steering assist may not operate.

●Pre-collision warning
While the pre-collision warning function is operating, if the s teering wheel is operated heavily or suddenly, the pre-collision warning may be canceled.
●Pre-collision brake assist
●Pre-collision braking
If either of the following occur while the pre-collision brakin g function is operating, it
will be canceled:
• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
●Emergency steering assist
When the turn signal lights are flashing, emergency steering as sist will not operate in
case of an emergency.
If any of the following occur while the emergency steering assi st function is operat- ing, it will be canceled:

• The accelerator pedal is depressed strongly.
• The steering wheel is turned sharply or abruptly.
• The brake pedal is depressed.
●Intersection right/left turn assistance (pre-collision warning)
When the turn signal lights are not flashing, support for turni ng left or right at an inter-
section which targets oncoming vehicles does not work.
●Intersection right/left turn assistance (pre-collision braking)
When the turn signal lights are not flashing, support for turni ng left or right at an inter-
section which targets oncoming vehicles does not work.
■Object detection function
The system detects objects based on their size, profile, motion, etc. However, an object may not be detected depend-
ing on the surrounding brightness and the motion, posture, and angle of the detected object, preventing the system
from operating properly. ( P.169) The illustration shows an image of detectable objects.
■Conditions under which the system
may operate even if there is no pos- sibility of a collision
●In some situations such as the follow-ing, the system may determine that there is a possibility of a frontal colli-
sion and operate. • When passing a detectable object, etc.
• When changing lanes while overtak- ing a detectable object, etc.• When approaching a detectable
object in an adjacent lane or on the roadside, such as when changing the course of travel or driving on a wind-
ing road

operate. • When the white (yellow) lane lines are difficult to see, such as when they are
faint, diverging/merging, or a shadow is cast upon them• When the lane is wider or narrower
than normal • When there is a light and dark pattern on the road surface, such as due to
road repairs • When a pedestrian is detected near the centerline of the vehicle
• When the target is too close • When there is insufficient safe or unobstructed space for the vehicle to
be steered into • If oncoming vehicle is present• If VSC function is operating
●In some situations such as the follow-ing, sufficient braking force or steering
force may not be obtained, preventing the system from performing properly:• If the braking functions cannot operate
to their full extent, such as when the brake parts are extremely cold, extremely hot, or wet
• If the vehicle is not properly main-
tained (brakes or tires are excessively
worn, improper tire inflation pressure, etc.)• When the vehicle is being driven on a
gravel road or other slippery surface • When the road surface has deep wheel tracks
• When driving on a hill road • When driving on a road that has inclines to the left or right
■If VSC is disabled
●If VSC is disabled ( P.212), the pre- collision brake assist and pre-collision
braking functions are also disabled.

4-5. Using the driving support systems
While driving on a road with clear
white (yellow) lane lines, the LTA
system warns the driver if the vehi-
cle 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*. Also, while the
dynamic radar cruise control is
operating, this system will operate
the steering wheel to maintain the
vehicle’s lane position.
The LTA system recognizes white
(yellow) lane lines or a course*
using the front camera. Additionally,
it detects preceding vehicles using
the front camera and radar.
*: Boundary between asphalt and the
side of the road, such as grass, soil,
or a curb
LTA (Lane Tracing
Assist)
Summary of functions
WARNING
■Before using LTA system
●Do not rely solely upon the LTA sys-
tem. The LTA system does not automatically drive the vehicle or reduce the amount of attention that
must be paid to the area in front of the vehicle. The driver must always assume full responsibility for driving
safely by paying careful attention to the surrounding conditions and operating the steering wheel to cor-
rect the path of the vehicle. Also, the driver must take adequate breaks when fatigued, such as from
driving for a long period of time.
●Failure to perform appropriate driv-
ing operations and pay careful attention may lead to an accident, resulting in death or serious injury.
■Situations unsuitable for LTA system
In the following situations, use the LTA switch to turn the system off. Fail-ure to do so may lead to an accident,
resulting in death or serious injury.
●Vehicle is driven on a road surface
which is slippery due to rainy weather, fallen snow, freezing, etc.
●Vehicle is driven on a snow-cov-ered road.
●White (yellow) lines are difficult to see due to rain, snow, fog, dust, etc.
●Vehicle is driven in a temporary lane or restricted lane due to con-
struction work.
●Vehicle is driven in a construction
zone.
●A spare tire, tire chains, etc., are
equipped.
●When the tires have been exces-
sively worn, or when the tire infla- tion pressure is low.
