Your vehicle may have the Electronic Stability Control (ESC) system.

You may feel or hear the system working, this is normal. See Electronic Stability Control (ESC) for more information.

When the ESC indicator light is on and either the SERVICE ESC or ESC OFF Driver Information Center (DIC) message is displayed, the system will not assist the driver to maintain directional control of the vehicle. Adjust your driving accordingly. See DIC Warnings and Messages for more information.
