Default red & blue dash lights on?

Upon cold start up, my girlfriends '00 NB can get a red, red flashing, or blue light, she thinks it might be the same light turning colors. They will go off after a few minutes. It can be freezing in the AM here. Is this a temp idiot light?

We don't have an owners manual yet, just a service.
Any pics here of the dash lights explaining what they are?

Thanks

Check your coolant level. I think the proper colour on startup is blue.

The coolant temperature light can come on either blue or red. It should be blue upon start up and then go out when the car reaches operating temp. If it beeps and flashes red its telling you the car is low on coolant. Occasionally I have seen the red coolant light flash and there is coolant and just the sensor in the expansion tank needs to be cleaned. Just be careful on the NB as there is no temperature gauge and when the red coolant light flashes you need to pull over immediately and check it.

It only displays upon cold start up.
I'll check the coolant/sensor.

Thanks.

Yup I will also say, I myself having a Beetle, that the blue color is saying that the car is cold and you should keep your revs low if you like your turbo in one piece for the long haul etc. flashing red and beeping means low coolant and I think that it does something else to indicate over heating condition.
