2384-5. Using the driving support systems
■If the PCS warning light illuminates and
a message is displayed on the
multi-information display
The system may be temporarily unavailable
or may be malfunctioning.
While driving on a road with clear
white (yellow) lane lines, the LTA sys-
tem warns the driver if the vehicle may
deviate from the current lane or
course
*, and also can slightly operate
the steering wheel to help avoid devia-
tion from the lane or course
*. Also,
while the dynamic radar cruise control
with full-speed range is operating, this
system will operate the steering wheel
to maintain the vehicle’s lane position
and when changing lanes (vehicles
with Lexus Safety System + A).
The LTA system recognizes white (yel-
low) lane lines or a course
* using the
front camera. Additionally, it detects
preceding and surrounding vehicles
(vehicles with Lexus Safety System +
A) using the front camera and radar.
*: Boundary between asphalt and the side of the road, such as grass, soil, or a curb

Driving
■Lane centering function
This function is linked with dynamic
radar cruise control with full-speed
range and provides the required assis-
tance by operating the steering wheel
to keep the vehicle in its current lane.
When dynamic radar cruise control with
full-speed range is not operating, the lane
centering function does not operate.
In situations where the white (yellow) lane
lines are difficult to see or are not visible,
such as when in a traffic jam, this function
will operate to help follow a preceding
vehicle by monitoring the position of the
preceding vehicle.
If the system detect s that the steering
wheel has not been operated for a fixed
amount of time or the steering wheel is not
being firmly gripped, a warning is displayed
on the multi-information display and the
function is temporarily canceled.
■Lane change assist function (vehi-
cles with Lexus Safety System + A)
This function is linked to the dynamic
radar cruise control with full-speed
range and provides assistance for per-
forming lane changes by operating the
steering wheel when you hold the turn
signal lever partway (lane change posi-
tion). ( P.185)
When lane change assist function is
operating, the acceleration and decel-
eration of the vehicle is controlled
while the preceding vehicle and vehi-
cles driven in the lane toward which the
turn signal is oper ated are monitored.
Use lane change assist function on
freeways and highways.
When the lane center ing function is not
operating, the lane change assist function
will not operate.
The lane change assist function should not
be operated when ch anging lanes on a
road that is diverging or merging.
