The easiest way to see if your car has mag ride is to go into the infotainment system —> under settings —> drive mode and suspensions option should be present. Another way is to find out is to look under the front or rear and you should see the ride height sensor (Red circle in the picture).
Also, here’s a really good article about magnetic ride control from GM Authority. They do a pretty good job explaining everything about MRC!
