During extreme steering maneuvers, the Electronic Stability Program[1] (ESP) system helps maintain control by sensing when the vehicle is starting to over- or understeer. The system automatically applies individual brakes or controls the throttle to help you stay safely on course.
Not all roads are paved or smooth. Wrangler Unlimited's four-wheel Antilock Brake System (ABS) has a unique rough road detection system that has a special program to assist Wrangler's stopping performance on gravel or dirt roads.
All-Speed Traction Control has a special set of calibrations specifically for driving in 4WD 4LO. To help crawl over obstacles and during heavy articulation activity, it applies the brakes more aggressively and for longer duration than traction control.
In a panic brake condition, Wrangler Unlimited's Brake Assist system applies maximum braking power, providing the shortest possible stopping distance.
Electronic Roll Mitigation[1] (ERM) uses innovative motion sensors that determine when a rollover may occur and applies braking force to the correct wheel or wheels to reduce the likelihood of such an accident.
Anticipating the need for additional traction, all of Wrangler Unlimited's four-wheel drive systems automatically respond to wheel slippage and improve vehicle stability.

- ESP[1] OFF
When you don't want the extra hand, Electronic Stability Program[1] (ESP) is specially tuned for performance handling so you can switch it off. In addition, All-Speed Traction Control works in tandem with the ESP. It has a special set of calibrations specifically for driving in 4WD 4LO. To help crawl over obstacles and during heavy articulation activity, it applies the brakes more aggressively and for longer duration than traction control.
- On-Road / Off-Road Four-Wheel Disc Antilock Brakes
Wrangler Unlimited's four-wheel disc Antilock Brake System (ABS) brake assist and traction control helps prevent wheel lockup for improved steering under extreme braking and slippery conditions, and aids in trail driving when in four-wheel-drive 4LO mode. ABS modulates the brakes to reduce stopping distances and improve steering control under braking.
- Tire Pressure Monitoring System
Wrangler Unlimited's standard Tire Pressure Monitoring System regularly checks inflation levels for optimal safety, security, performance and fuel economy. If the levels are off, a warning light will illuminate on the instrument panel. It can save fuel too. According to fueleconomy.gov, you can improve your gas mileage by around 3.3% by keeping your tires inflated to the proper pressure (that's up to 11 cents / gallon savings!). Proper inflation also benefits the life of your tires.
- Hill Start Assist
Wrangler Unlimited's Hill Start Assist (HSA) assists drivers when starting a vehicle from a stop on a hill by maintaining the level of brake pressure applied for a short period after the driver's foot is removed from the brake pedal. If throttle is not applied within a short period after the driver's foot is removed from the brake pedal, brake pressure will be released.
