Mazda RX8 - Radiator warning light

[nike 5]

Hi
I am on holiday, in Switzerland with a RX8
When driving the radiator warning light periodically comes on.
To clear this I have pressed the clutch, and let the revs drop. This seems to clear the problem for 20 minutes or so.

There does not appear to be a type of driving that causes the light to come on (gentle motorway/town/backroad driving).

The user manual (that came with car) explains all the warning lights on dash, says I should check water level (checked and ok)
Engine temp shows normal.
No other symptoms.

User manual says that i will need to take car to a dealer.
What could be wrong with it?
Guessing that it is not a bad connection, as to solve it I just need to depress clutch and let revs drop. Also the user manual mentions it, so it sounds as if it is a known warning indicator.
Could I be damaging car?

Any help/suggestions would be appreciated.

Thanks

Thanks for your replies, I shall not worry about it, and fix it when I get home.

I am with you, in not understanding how depressing the clutch and letting revs drop, would help to clear warning the warning light. But on this car it clears it within seconds.

Thanks again.

Hi back in the UK now.
Incident free, the car continued as before, performing well and keeping a steady temperature, and not losing water.
Will look into getting a new header tank shortly.

We shared the driving, and I really enjoyed driving my friend's RX8.

Would recommend anyone to drive the alpine passes, even if everything is expensive.
I look forward to going back next year in my car, even if that is without air conditioning.

Thanks again for all your help.
