Air pressure sensor. Look in your owners manual.

The yellow triangle with an exclamation mark will typically be accompanied by a message explaining what's gone wrong. Hopefully it will be self-explanatory - such as a low reservoir for the windscreen washer system.

I'm guessing(bad charger?) Try another charger.

It means "something is wrong". You need to check the messages to find out.

There's an error.

I suggest that you close your facebook or browser and open it again. It just needs a refresh.

I hope this helps!

If it looks like a deflating tire with an exclamation mark inside, its the check your tire pressure light.

If its a triangle with exclamation mark inside its the check engine light.

1. You can try to disconnect the battery from car terminals, waiting for 30 minutes and connect again the cables in order to reset the ESP Electronic Control Unit (ECU).
2. If this procedure does not work you must use a diagnostic equipment connected to the Data Link Connector (DLC) of the car. The ESP ECU fault memory can only be accessed and erased using diagnostic equipment connected to the DLC.
Note: ESP function includes ABS (Antilock Braking System) function!

I have IE7 and I was getting the same error with the yellow triangle with an exclamation point inside. I added this to my TRUSTED sites and it works perfect know.

This happens when you lose your connection, refresh the page and you should be able to continue chatting.

If this doesn't work, then facebook might be doing some maintenance work on their chat module.
