While parked up engine off...Is it possible to open the windows without starting up the engine.

Yes. You can turn on the 'ignition' without starting the engine by pressing the start button for a few seconds without your foot on the clutch. Open window then press again to turn off.

...or without depressing the brake (if automatic...) ...

Be true to yourself. That way happiness lies...

Hi,

Or if key fob is not docked, hold down the unlock button for more than 3 secs. All windows will open. Kola is the big solid black German Shepherd, Dobbie is.......a breed you've never heard of......yet;)

...

or use a Birmingham Screwdriver...

Be true to yourself. That way happiness lies...

Thanks all - fresh air

Now and again, the unlock button on my key fob has been activated while in my pocket and I have come back to the car with all the windows wide open.  garioch43
