Electronic Stability Control (ESC) The vehicle has an Electronic Stability Control (ESC) system which combines antilock brake, traction and stability control systems and helps the driver maintain directional control of the vehicle in most driving conditions. ESC activates when the computer senses a discrepancy between the intended path and the direction the vehicle is actually traveling. ESC selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the desired direction. When you first start the vehicle and begin to drive away, the system performs several diagnostic checks to ensure there are no problems. The system may be heard or felt while it is working. This is normal and does not mean there is a problem with the vehicle. The system should initialize before the vehicle reaches 20 mph (32 km/h). If the system fails to turn on or activate, the ESC/TCS light comes on, and the ESC OFF and/or SERVICE ESC message displays. For more information, see Driver Information Center (DIC) on page 3-34. This light flashes on the instrument panel cluster while the ESC system is both on and activated. When the system activates, an ESC ACTIVE message displays on the DIC. The system may be heard or felt while it is working; this is normal. Continue to steer the vehicle in the intended direction. When the light comes on and the message(s) SERVICE ESC, ESC OFF, or both are displayed, the system will not assist the driver in maintaining directional control of the vehicle. Adjust your driving accordingly. The Electronic Stability Control (ESC) system is automatically enabled whenever the vehicle is started. To assist the driver with vehicle directional control, especially in slippery road conditions, the system should always be left on. But, ESC can be turned off if needed. If the vehicle is in cruise control when the system begins to assist the driver maintain directional control of the vehicle, the ESC/TCS light will flash and the cruise control will automatically disengage. The cruise control system may be reengaged when road conditions allow. See Cruise Control on page 3-9. 4-6
