4-5. Using the driving support systems
*: If equipped
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.

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.
