The 'S' bit  or winter mode is also designed to work in such situations where, say, you get stuck in mud or whilst launching your boat on a seaweed heavy slip in the south of France at the height of summer. Not just for snow or ice, but that one is more easily portrayed in the icon on the button.

That would be one cool looking button though wouldn't it?  ;)

I'm thinking along the lines of a nice yacht outline, rather than a snowflake.....

It's like the alarm button, showing the intruder running away.

A true representation should actually show your neighbours closing their windows.  ;D

......I'm sure that on my old P Reg, it only worked in low temperatures. Perhaps they changed it, or perhaps I'm wrong about that too.
Probably!   ;)  My even older G reg Senator worked the same.  ::) (different cutting out speed though.)

I thought the "S" button made it change up later and the "Snowflake" made it change up sooner. Is it possible to use both together? Must try that.[smiley=undecided.gif]

Not quite, Snow makes it lock out 1st and 2nd so that car is more controllable in slippery conditions. Switch off when you go above 50mph (coz obviously not slippery any more, as you wouldn't be going faster in those sorts of conditions ;)), or by pressing snowflake again...

Only once, and that ended sideways into a ditch.   [smiley=shocked.gif] [smiley=cry.gif]

According to the handbook it switches off at 80 KPH, which, I think, is about 50 MPH.

Snow button works fine until you get caught in heavy snow in Cornwall in November, then after about 1/2 hour of backlaning to avoid traffic it all gets so hot and bothered that it stops working, leaving you to start off in first!! LOL.  Eventually came back on again after things cooled down.

Snow in the pollen filter doesn't do it much good either.

Snow mode will put extra strain of g/b as there will obviously be much more slip on the gearbox. And due to speed (very slow), the autobox radiator is not going to cool it down much.

If you've had this happen, its probably burned the g/b fluid, so you'll need to change it...

I've been watching this thread with interest.

My 2.2 does not 'hold' in the gears when cold, it changes normally.

The only problem I ever had with the auto box holding in gear was when the engine was hot and I started off on a down hill slope, it would not change out of 1st until around 3,500 rpm.

The auto ECU was changed under warranty, never had any problems since.

I wouldnt worry about it too much AA.....but it should really.
Mine does, pull away from cold (and its still on petrol at this point) and it revs to about 3-3.5k before changing.....even constant speed or slowing down it will hold the revs high for the 1st 1/2mile or so.

Just had a thought AA.....

Does your sports mode work ok?......coz i think gearbox just goes into sports mode for a short while when cold (ie holding the gears and letting it rev higher)
