LTA (Lane Tracing
Assist)
When driving on highways
and freeways with white
(yellow) lane lines, this
function alerts the driver
when the vehicle might
depart from its lane or
course
*
and provides assis-
tance by operating the
steering wheel to keep the
vehicle in its lane or
course
*
. Furthermore, the
system provides steering
assistance when dynamic
radar cruise control with
full-speed range is operat-
ing to keep the vehicle in its
lane.
The LTA system recognizes
white (yellow) lane lines or a
course
*
using the front cam-
era. 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
WARNING
■ Before using LTA system
● Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle 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 atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct 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
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
● When not using the LTA system,
use the LTA switch to turn the
system off.
■ Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
● Vehicle is driven on a road sur-
face 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
construction work.
