Vehicles with a tyre pressure monitoring sys-
tem: if an emergency spare wheel is fitted, the
tyre pressure monitoring system cannot func-
tion reliably. For a few minutes after an emer-
gency spare wheel is fitted, the system may
still display the tyre pressure of the removed
wheel. Only restart the system again when the
emergency spare wheel has been replaced
with a new wheel.
