This Preliminary Information communication provides information to the technician with additional information on the functionality of Lane Keep Assist. Starting with 2016 model year Lane Keep Assist Regular Production Option Code \(UHX\) replaced Lane Departure Warning Regular Production Option Code \(UFL\).
