TPMS with Tire Fill Assist and the Compact Spare Tire
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 Pressure
Monitor Problem appears on the driver information interface, but this is normal.
If you replace the tire with a specified regular tire, the warning message on the
driver information interface and the low tire pressure/TPMS indicator will go off after
a few miles (kilometers).

The system cannot monitor the pressure of the spare
tire. Manually check the spare tire pressure to be sure
that it is correct.
Use the TPMS specific wheels. Each is equipped with
a tire pressure sensor mounted inside the tire behind
the valve stem.
