Vehicles with a tire pressure monitoring
system: If an emergency spare wheel is
installed, the tire pressure monitoring sys‐
tem cannot function reliably. For a few
minutes after an emergency spare wheel is
installed, the system may still display the tire
pressure of the removed wheel. Only restart
the system again when the emergency spare
wheel has been replaced with a new wheel.
