Hi wanda2,
Thank you for the donation.
The S mode is operated by a small switch on the gear shift lever, just below the push button for movinhg in and out of Park or Reverse. If you had accidentally pushed on the button, pushing it another time would turn it off.
If the mini button is not responsive, the wires for the circuit could possibly be shorted.
If the light is blinking while driving, which would not allow you to operate the switch, an error has been detected in the control system and you have to retrieve the trouble code to find out what is wrong.
The S mode is applicable for normal driving as well and the only difference would be a longer time frame for it to upshift if aceleration is brisk. Under normal driving conditions, you would not find much difference.
