Whenever you go around a corner and the computer detects some wheel slippage, it will turn on the light for a few seconds so you'll know to slow down. If you push the esp button to the right of your 4 way hazard light switch, it will also turn on the light indicating you have partially disabled your electronic stability program. The light will stay on until you hit the switch again or turn the Jeep off, whichever comes first.
Edit: The light can come on going straight too.
