If you are driving with the emergency spare
wheel fitted, the tyre pressure loss warning
system or the tyre pressure monitor cannot
function reliably. Only restart the tyre pres-
sure loss warning system or tyre pressure
monitor when the defective wheel has been
replaced with a new wheel.
Vehicles with tyre pressure monitor: after
fitting an emergency spare wheel, the system may still display the tyre pressure of the
removed wheel for a few minutes. The value
displayed for the position where the emer-
gency spare wheel is fitted is not the same as
the current tyre pressure of the emergency
spare wheel. Removing the emergency spare wheel
