ON THREE OCCAISIONS, THE DRIVER SAFETY ASSIST SYSTEM SHUT OFF. EACH TIME THERE WERE NO OBSTRUCTION IN RADAR AND THE DAY WAS NOT A HOT DAY. THE AUTO ASSIT CRUISE CONTROL SHUT DOWN TO. SHUTTING THE CAR OFF SEEMED TO RESET. I WAS UNAWARE BY PRESSING THE MAIN SWITH ON STEERING WHEEL WILL RESET THE SYSTEM. BUT AS I SAID TURNING OFF THE VEHILCE SEEMS TO RESET. I CHECKED LANE DEPARTURE BUT IT AFFECTED ALL SAFE DRIVING SYSTEMS. YOUR SYSTEM WOULD ONLY ALLOW ME TO CHECK ONE BOX IT WOULD NOT LET ME CHECK.
