[Warp Ten]

Baffling. Your question intrigued me so I looked through my 540xi owner's manual and could not find this symbol. Googled BMW warning lights and got a list of 68 from BMW of Escondido but it did not show your symbol. They did say the following:

BMW Warning Lights
Presented by BMW of Escondido
Some of these warning lights will appear when you first
start the car, along with how many miles you have until
your next scheduled service.
• Red warning lights are associated with danger, and
there is a serious situation which must be checked
out before continuing.
• Orange and yellow warning lights are less critical, but
something is wrong and should be resolved as soon
as possible.
• Green or blue warning lights indicate that your vehicle has a technological feature enabled.

I also went further and Googled "BMW 530e warning lights" and got lots of responses with lists and pictures of lots of warning lights, including one that had 308 on it. I did not see your "car with a thermometer" symbol however. If I had to guess it may have something that has to do with interior car temperature, perhaps suggesting some ventilation feature is active? I suggest checking in with your dealer service guys and let us know the answer. Good luck.--Bob
