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-

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

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.

This mode employs a radar to detect the presence of vehicles up to approx-
imately 100 m (328 ft.) ahead, d etermines the current vehicle-to-vehicle fol-
lowing distance, and operates to maintain a suitable following distance from
the vehicle ahead. The desired vehicle-to-vehicle distance can also be set
by operating the vehicle-to-vehicle distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distanc e may become
shorter.
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed appe ars
When a vehicle is detected running ahead of you, the system automatically deceler-
ates your vehicle. When a greater reduction in vehicle speed is necessary, the sys-
tem applies the brakes (the stop lights will come on at this ti me). The system will
respond to changes in the speed of the vehicle ahead in order t o maintain the vehi-
cle-to-vehicle distance set by the driver. Approach warning war ns you when the sys-
tem cannot decelerate sufficiently to prevent your vehicle from closing in on the
vehicle ahead.
When the turn signal lever is operated and your vehicle moves t o an overtaking lane
while driving at 80 km/h (50 mph) or more, the vehicle will acc elerate to help to over-
take a passing vehicle.
The system’s identification of what is an overtaking lane may b e determined solely
based on the location of the steering wheel in the vehicle (lef t side driver position
