LTA (Lane Tracing Assist)
*
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 with
full-speed range (P.248) is oper-
ating, this system will operate the
steering wheel to maintain the vehi-
cle’s lane position.
The LTA system recognizes white

ally, it detects preceding vehicles
using the front camera and radar.
