LTA (Lane Tracing Assist)

: If equipped
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
assistance by operating the steer-
ing 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 operating
to keep the vehicle in its lane.
The LTA system recognizes white
