Your brake pads need to be replaced. There is actually a sensor wire that breaks when the pad is ground down too far, interrupting a circuit to warn you of imminent pad failure.
On older models of Volkswagen this symbol was for the ESP and ASR systems, Electronic Stability Control or Anti-Slip Regulation. If it is on solid it typically represents a fault unless the function has been turned off. This is done with a button on the dash that says ESP or ASR. If it is for a fault it is normally a fault with either the ESP/ASR or sometimes with the ABS. Normally with an ABS fault you would have an ABS warning. The brake pad warning is two paranthesis with an exclamation point in between them.
It is the traction control warning light
low tire warning
The warning light in the bottom area of your tachometer that looks like a circle ( gear ) with an exclamation mark in the middle is your " check transaxle " ( transmission ) warning light . If the light stays on take your vehicle in for servicing
One of your headlights have burned out.
The red exclamation point in a circle is the parking brake indicator.
In the Chevy Aveo, the exclamation point warning light in a circle, means that the air pressure is low in one or more of the tires. This is per the owners manual.
Also a3 red triangle with a circle around it
Your parking brake is probably on.
I believe this is a warning for the brake pads.
low tire pressure
the red exclamation mean the system updates fail and yellow exclamation means clint needed patches
the blue caution triangle with an exclamation mark, next to the persons name means that there were messages that did not send and to get rid of the blue triangle you can either send the messages or delete them. the messages that did not send should have a red circle with an exclamation mark next to it.
