Door Warning Reflectors Located in Regal's door panel, these reflectors help alert oncoming drivers to an open door. Anti-Lockout Feature Regal's power door locks will not work if the key is left in the ignition, the ignition is turned to OFF and the driver's door is open. The feature can be overridden if the power door lock switch is held for more than three seconds Electrochromic Heated Power Sideview Mirrors In addition to being fully adjustable from the driver's seat, Regal's sideview mirrors are heated to help keep snow and ice from blocking the driver's vision to the rear. Also available on Regal is an electrochromic-automatic driver's side rearview mirror, which dims to reduce glare from the headlights of cars approaching from behind.
