LKA (Lane-Keeping Assist)
When driving on highways and
freeways with white or yellow lines,
this function alerts the driver when
the vehicle might depart from its
lane and provides assistance by
operating the steering wheel to
keep the vehicle in its lane. Further-
more, the system also provides
steering assistance when dynamic
radar cruise control with full-speed
range is operating to keep the vehi-
cle in its lane.
The LKA system recognizes visible
white or yellow lines with the front
camera on the upper portion of the
front windshield.
Functions included in LKA sys-
tem
Lane departure alert function
■
When the system determines that the
vehicle might depart from its lane, a
warning is displayed on the multi-infor-
mation display, and either the warning
buzzer sounds to alert the driver.
When the warning buzzer sounds, check
the surrounding road situation and care-
fully operate the steering wheel to move
the vehicle back to the center of the lane.
Steering assist function
■
When the system determines that the
vehicle might depart from its lane, the
system provides assistance as neces-
sary by operating the steering wheel in
small amounts for a short period of
time to keep the vehicle in its lane.
If the system detects 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 dis-
played on the multi-information display
and the warning buzzer sounds.
