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.
ESP automatically applies individual brakes or controls the throttle to help you stay safely on course. When you don't want the extra hand, ESP is specially tuned for performance handling so you can switch it off.
Grand Cherokee's four-wheel disc Antilock Brake System (ABS), brake assist and all-speed traction control helps prevent wheel lockup for improved steering under extreme braking and slippery conditions. The system also aids in trail driving when in four-wheel-drive 4LO mode.
Anticipating the need for additional traction, all of Grand Cherokee's four-wheel drive systems automatically respond to wheel slippage and improve vehicle stability.

- Hill Descent Control
Hill Descent Control with grade sensing allows a smooth and controlled hill descent on rough or slippery terrain without the driver needing to touch the brake pedal. This system applies the brakes to each wheel individually when needed to reduce forward motion while negotiating down steep grades.
- Hill Start Assist
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.
- Tire Pressure Monitoring Systems
Both of Grand Cherokee's Tire Pressure Monitoring Systems regularly check inflation levels for optimal safety, security, performance and fuel economy.
The Tire Pressure Monitoring Display system displays individual tire pressure in the Electronic Vehicle Information Center (EVIC). If the levels are off, a Tire Pressure Monitor warning lamp will illuminate on the instrument panel. 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.
