However, thought I should share the following:
In the event you need to pump up an affected tyre, and assuming you are not on a garage forecourt, you’ll need to plug in a 12v mobile pump (see Halfords or similar) and….
Clip the driver’s seatbelt into position even though nobody in the seat. Leave the keys static in the car, and then press the starter button on the steering wheel column so that the 12v socket becomes live. The display unit being active, despite no seat occupant, confirms your success.
Alternatively, buy a foot pump
Hope it helps, especially for any occasional drivers who might be on their own when/if happens.
