switching off tyre pressure monitor

[dartissimus]

I've just fitted winter tyres & rims.
The tyre pressure monitor on the dash informs me every time I start the car that it's not working.

Is it possible to switch this alert off, and then back on in the spring? (Without going to the dealer?)

Finally sorted this problem, bought a set of monitors from the Wheel Shop on Ebay.
I spoke to Carl, explained which model, he said his monitors would set themselves up within 20 miles. In fact it took only two.
Cost £140, but now all working, legal and no dealer prices paid.
The car is happy and so am I.
