This is what I learned about my ESC. Not sure if this will help in your decision. This is from my blog post on August 6, 2015 when I was reading my manual
ESC - Electronic Stability Control
Basically this system can tell which way you intend to drive, and if the vehicle's path is not going that way, it will apply the proper brakes to get you back on the right path.
This ECS system has 3 different modes you can control with a button on your control panel under the radio -- On, Partial Off and Full Off.
When you are in 4 high you want this system ON.
For the partial off mode the Traction Control System is disabled but not the Brake Limited Differential. You want to be in this mode if you are in deep sand, snow or gravel, and you need more wheel spin then would normally be allowed.
If you want ESC in Full Off you need to press and hold the switch for five seconds. This turns off the engine torque reduction, and the enhanced stability control. You will want to use this mode while off-highway or off-roading.
Now... if you forget to turn this system back on when you get back on the highway... it's okay... because the computer thinks for you. Once you hit 40 mph it automatically goes into partial off mode.
And good news again folks... No worries about pushing the button when you shift your Jeep into 4 low. The computer automatically knows to switch off the ESC to Full Off.
