The Electronic Stability Control (ESC) system is an advanced computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is accomplished by selectively applying any one of the vehicle's brakes and reducing engine power. The ESC system comes on automatically whenever you start your vehicle.

The SERVICE STABILITY CTRL message may be displayed in the DIC after first driving the vehicle and exceeding 30 mph 48 (km/h) for 30 seconds. The ESC system is off until the message has turned off. This could take up to 15 minutes. See DIC Warnings and Messages for more information.

The SERVICE STABILITY CTRL message will stay on if there is a problem with the system. When this message is on, the system is not operational. Adjust your driving accordingly.

ESC can be turned off using the traction control button. To disable ESC, press and hold the traction control button for five seconds. ESC can be activated again by pressing the traction control button.
