ations, such as the following, the
emergency steering assist may not
operate.
• When the white (yellow) lane lines are
difficult to see, such as when they are
faint, diverging/merging, or a shadow
is cast upon them
• When the lane is wider or narrower
than normal
• When there is a light and dark pattern
on the road surface, such as due to
road repairs
• When the target is too close
• When there is insufficient safe or
unobstructed space for the vehicle to
be steered into
• If oncoming vehicle is present
• If VSC function is operating
● In some situations such as the follow-
ing, sufficient braking force or steering
force may not be obtained, preventing
the system from performing properly:
• If the braking functions cannot operate
to their full extent, such as when the
brake parts are extremely cold,
extremely hot, or wet
• If the vehicle is not properly main-
tained (brakes or tires are excessively
worn, improper tire inflation pressure,
etc.)
• When the vehicle is being driven on a
gravel road or other slippery surface
• When the road surface has deep
wheel tracks
• When driving on a hill road
• When driving on a road that has
inclines to the left or right
■ If VSC is disabled
● If VSC is disabled (P.417), the pre-
collision brake assist and pre-collision
braking functions are also disabled.

LTA (Lane Tracing
Assist)
*
While driving on a road with
clear white (yellow) lane lines,
the LTA system warns the
driver if the vehicle may devi-
ate 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.368)
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 cam-
era. Additionally, it detects pre-
ceding vehicles using the front
camera and radar.
