TPMS 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 or 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.
2 TPMS Calibration P. 469
The system cannot monitor the pressure of the spare tire. Manually check the spare
tire pressure to be sure that it is correct.
