Help- coolant system failure!

First time post, do hope this is okay. 
I picked up my 2012 911.1 S yesterday. At last!. But on the drive home the Coolant system failure message came up in yellow. I kept an eye on engine temperatures the rest of the journey. water stayed at a constant 90 degrees. No loss of power - I think. 

i have a good RAC warranty but how long should I drive with this? I’m hoping it’s a sensor etc. Should I just get my local Porsche dealer to reset and see if it happens again? I’ve just got the car and I don’t really want to drive it straight to a garage? 
any help/ thoughts appreciated.
but looove the car.

    Check the coolant level first in the clear tank located in engine compartment.

    Welcome Joe.  I've moved this to the 991 forum which may be more relevant.

    I'm speeding because I have to get there before I forget where I'm going.

    That's very disappointing for you Joe, having just taken delivery of the car. Personally, I think you should take the car back to the supplying dealer ASAP to get the problem resolved - they shouldn't have given you the car with a known fault.
    As Geoff says, the first port of call should be to check the coolant level in the expansion tank as well as checking for signs of leakage under the car when it's been standing. Loss of coolant from the tank cap itself is a possibility - make sure that the surfaces are clean and that it's tightened properly.
    Just be aware that as with many modern cars the coolant temperature reading is just an indication and not necessarily a "true" reading and you need to pay particular attention if it starts climbing rapidly and/or if you get a warning light (check your Driver's Manual for full details).

    Welcome Joe. Hopefully this is just a teething problem and that your 991 will eventually be the great Porsche that we all enjoy. 
    There has been very good advice above: just to add that a leaking/disconnected vacuum hose can also give this fault. 
    Good luck and do please let us know the outcome.

    Many thanks for all your helpful and kind comments. An update. After spirited drive this afternoon, just before Dennis hits us, the fault has failed to re appear. hopefully this indicates it not too serious and may even have been a teething problem. I will however look at the expansion tank suggestion. 
    many thanks - does anyone not drive in sport ??🤣
