Either yo have shifted into four wheel drive, or there is a malfunction in the four wheel drive system.
Without know what the warning light say's, all I can tell you in Yellow means caution.
engine light
Did not receive a owners manual when I purchased my Jeep Liberty 2004. There is a warning light that looks like a transmission lighting up - what does it mean?
Engine Warning Light
A Mitsubishi L200 yellow warning light on the dash could mean the ABS is having issues. It is best to check the owner manual for defined warning light meanings.

The yellow dashboard warning light you are seeing on your 2003 Dodge Neon is most likely the fuse warning light. You will most likely need to go to a mechanic to find out which fuse needs to be replaced.
No, have it looked at by a professional.
A yellow warning light that looks like a foot with a yellow circle and small lines going around it is on. What does it stand for?

Caution or warning
It is not a light, but a decal or printed type. It is a specification, I believe. Has nothing to do with a warning or message.
