I have a exclamation ! light on in my car,what that mean?

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.

Look in your owners manual

Can also find those symbols on the internet

it is the tire pressure monitor. It means one of your tires has low air pressure.

The exclamation point does not mean anything , I assume your engine light is on,then that means you have a problem with the engine /emissions .you need to it diagnosed with a code reader.

my exclamation light turned on in my 05 nissan pathfinder what does this mean

This means you have a light buld not working some where in the front or rear lights.When you fix the problem the light will automaticy go out hope this helps.

Alright, so if this light is red with an exclamation mark (!) in it, that would mean that your emergency brake is engaged

Transmission warning light :)

thats your TPMS light, Tire Pressure Monitoring System. The light means that one of your tires is low on air, so check them all and fill them to the specified amount, which will be located on the drivers side door jamb.
