Before you start the car, depress the SAT and the CD track forward button and hold them. Turn the key on but do not start the car. Depress the gas pedal 5 times and then the brake pedal twice. Keeping your fingers on the buttons, reach back and open your passenger door. Turn the key off. Turn the key back on. Your panel should read "hello" and then flash a message for about .02 seconds. Write that message down. Go to
www.mazda.com and enter that message in a search field. Mazda USA will send a signal to your car unlocking the PSI gauge located in the information panel on the dash. (ricer)
