LKA (Lane-Keeping Assist) (If Equipped)
Lane departure warning function
If the system judges that the vehicle may deviate from its lane, it alerts the driver using
rapid beeping, indications on the multi-information display, and a sensory warning given
via the steering wheel.
Lane keeping assist function
This function will be active when the vehicle-to-vehicle distance control mode of the
cruise control is set with vehicle speed above approx. 45 mph (approx. 72 km/h) and
while the lane departure warning function is active. When the lane keeping assist func-
tion is active, a slight steering torque will be applied, to help the driver maintain the vehi-
cle inside the lane.
■Turning the LKA system on
The lane departure warning function and lane keeping assist function will be activated
depending on the recognition condition of lane markers, vehicle speed and the setting of
radar cruise control (vehicle-to-vehicle distance control mode).
Press the “LKA” switch to activate the sys-
tem.
“LKA” indicator will come on.
Press the switch again to turn the LKA
system off.
While driving on a freeway or motor highway that has lane markers, this system recog-
nizes the lanes using a camera as a sensor to assist the driver with staying in the lane. The
LKA system has two functions.
