I have a 2008 Dodge Avenger. Recently a red exclamation point light comes on in the dash for just a few seconds, particularly on a wide curve, like a freeway exit. I know the yellow light means air pressure in the tires is low, but I can't find anything in the manual about a red exclamation point. The yellow light for tire air pressure does not come on, but I do have nitrogen in the tires. Does that make a difference? Thanks.

SOURCE: red exclamation light has come up on dash - what does it mean

man this one was a challenge. however i did learn that this vehicle is autralian. pretty cool i might add. however the symbal is basically the same thing as a check engine light. took me 2 hours to find that answer for ya.

SOURCE: How do you turn off a tire pressure sensor dash

check the tire pressures in ALL tires not just the 4 on the ground but the sapre also. If the pressures are all correct and the light is still on you may need to take it to a tire store such as good year or firestone or eve you local dealr to have the tpms SYSTEM checked out, (TPMS Tire Pressure Monitoring System)

SOURCE: After the tire pressure warning light came on, I

remove the battery terminals then re connect them.

It means you have a tire that has low air pressure air up the tires and it will turn off automatically. Assuming you have radials stop at any gas station and air them up to 32 PSi for firmness and better fuel mileage or 28 PSI if you like going around corners a little faster cause the tire to grab the road better. Also any tire shop will air them up for you if they are not busy.

Does it look like the one toward the bottom of this page? http://www.aa1car.com/library/warning_lights_lexus.jpg
I'm pretty sure that is a tire pressure warning light. You can find a key for this in the owners manual if you have it still.
