If you replace a flat tire with the spare tire, the low tire pressure/TPMS indicator comes on while you are driving. After driving for a few miles (kilometers), the indicator will start blinking for a short time and then stay on. Tire Pressures Low appears on the driver information interface*, but this is normal.
Calibrate the TPMS when you replace the tire with a specified regular tire.
The system cannot monitor the pressure of the spare tire. Manually check the spare tire pressure to be sure that it is correct.
