How do you reset the low tire pressure indicator on the dash after the tires are up to the correct pressure?

set the tire pressures.turn the key to the on position without starting it and push the tpm button in and hold it.it should initialize and light will go out.turn key off and then on again and start it.This vehicle is a Z-3?im not sure that z3s were availible with tire pressure monitoring.i could be wrong or aftermarket.let me know if that works.some monitor tire pressure by the actual wheel speed and some have pressure sensors and may require to be driven for a few miles to intialize
