No matter what I do I cannot get the passenger seat to remember a setting. I put car in Neutral with foot on the brake pedal, press and hold the "Set" button for a couple of seconds then press and hold the #1 memory setting button. The #1 button does not issue a confirming chime. What am I doing wrong? I have tried this procedure with a person in driver's seat and reaching over, people in both seats and just a person in passenger seat (so, no, there is no foot on brake pedal.
