Some drivers may notice a howl or groan sound while driving straight after a low speed spirited turning event. On SRT vehicles only, when the vehicle has been switched to the “Full On” ESP mode, the ESP event lamp continues to flash. This does not affect the functionality of the ESP system in any way. The system can be returned to “normal Full-On” mode by briefly pressing and releasing the ESP Off switch. The system will reset itself each time the ignition is cycled.
