Anti-Lock Light is On

Antilock light is on I don't notice any problems, brake fluid is near max level and brake pedal feels stiff.

Just the anti-lock light? Or is there a Service Vehicle Soon light and a Trac Off light?

It's the only light that I see on the Instrustment cluster and It turns on 20 seconds later when key is in acessory position or start and stays on solid nothing else is lighten up.
