Low Outside Temperature Warning
« on: 06 October 2008, 09:20 »
Hi guys, tried to find out about this in the manual to no avail.

When you get the snowflake symbol on the dashboard display indicating it is less than 3°C what functions are automatically started on the car?

I'm specifically interested in whether wing mirror heating is turned on?

TIA

I'm sure its 4 deg when the Snowflake symbol lights up?
Nothing else is activated, the mirrors are heated by turning the mirror adjuster knob to the heating position (turn it towards front of car)

I was under the impression no functions are switched on, it's just a warning to yourself that the roads may be icy.

Ah right, my BMW used to turn the mirror, windscreen and rear window heating on when the outside temperature dropped below 3°C. Thought it was a neat feature.

On my old Leon, what REALLY P1ssed me off....

When it had the cold temp warning on the dash a "safety feature" would turn off the air con compressor...so no air con and I probably use my air con more in the winter to turbo de-mist the windscreen than in the summer (esp with this weather!)

dunno if the mk5 does this.

No, don't think so.

Sure it does, might not show a symbol thats its off but it will be - you want it to anyway otherwise it could freeze up and you would knacker it up.

You're saying that if the snowflake symbol is on the air-con turns off and doesn't deliver any heat to the cabin?

Absolutely none.  The snowflake is just a visual warning to indicate that there may be ice, and/or black ice on the roads - and that you "should adapt your driving style accordingly".  :nerd:

Nope, as others have said, door mirror heating is ONLY activated by rotating the knob on the drivers door to the correct position.  However, be WARNED, the mirror heating is one of the first things to be over-rided and automatically turned off when the ECU senses a too high an electrical demand.
