LKA (Lane-Keeping Assist) (if equipped)
While driving on a freeway or motor highway that has lane markers and no sharp curves,
the system recognizes the lanes using a camera located above the inside rear view mir-
ror as a sensor to assist the driver with staying in the lane. The LKA system has two func-
tions.

rapid beeping, indications on the multi-information display, and a sensory warning
given via the steering wheel.
