My TPMS light came on this morning. The light on the dash is under the "D" for drive. Does that mean it's a certain tire e.g. front driver, rear driver? Or do I need to check them all to find the low tire. Thanks, Tom
If yours doesn't show displays for individual psi readouts then you need to find the one(s) that are causing the warning. Cold weather will make tire pressure go down and if yours was on the edge of being too low then the overnight cold could trip it.
Do check them all to include the spare. Best bet is to adjust your psi in the morning. Adjust pressures before you drive and when outside temp is cooler/cold. Be sure to use an accurate tire pressure gauge!
