Some cars have tire pressure sensors that can cause an indicator with an exclamation point to appear on the instrument panel.

Check the pressure in all of your tires.

Your car manual (probably crammed into your glove box somewhere) will have a diagram of all the instrument panel lights and a brief description of what they all mean.

That is the hand brake. it is on.

double posted, backup one. and read.

Google the kind of car and it's year. Add the word ...dash symbols.

thats tire pressure its a sensor that reads your pressure and once you get low it light the dash indicator (yellow exclamation point) and if you check the pressure yourself with a tire gauge and it reads fine then you have a bad sensor.

The waring kight with the triangle and exclamation mark is waring you that the brake pads are close to tuoching the disc's the waring sensor on the brake pad has shorted. It's so you do not scrap the disc's.

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.

That exclamation light on the dash board indicates low tire pressure. Check the air in all your tires and make sure they are all filled to proper levels and it should turn off.
