EXCLAMATION mark on dash is lit

[rjchoops]

My wife just called me and said the exclamation point is lit up on the dash and the manual is in the car. Does anyone know what that light signifies?

If it's this symbol, it is low tire pressure:



Usually appears if the weather is cold and one or more of your tires are low. Inspect all four tires for leaks and measure the tire pressure, add if necessary.

Like jmbones said, it's just low tire pressure. Just fill up the tires with air and drive the car for a few minutes at (I believe) 25mph and the light should go off.

I called her and described the picture / symbol you posted and sure enough that's it. I'll check the tires when she gets home. Thanks.

You can also look in the glossary at the top of the page and read some threads about this, there is an FAQ describing the system and a thread of people having problems which might be a good idea to skim if you have the time.

if you install winter tires with new wheels and no TPMS then it will cause that to come on at all times too.
