Electronic Stability Control (ESC) The vehicle may have an Electronic Stability Control (ESC) system which combines antilock brake, and traction and stability control systems that help the driver maintain directional control of the vehicle in most driving conditions. When the vehicle is started and begins to move, 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 3-39 and Electronic Stability Control (ESC)/Traction Control System (TCS) Indicator/Warning Light on page 3-31. This light flashes on the instrument panel cluster when the ESC system is on and activated. ESC activates when the computer senses a discrepancy between the intended path and the direction the vehicle is actually travelling. ESC selectively applies braking pressure at any one of the vehicle's brakes to help steer the vehicle in the direction which you are steering. When the system activates, an ESC ACTIVE message displays on the Driver Information Center. See DIC Warnings and Messages on page 3-42. This light also flashes on the instrument panel cluster when the ESC system is on and activated. A noise may be heard or a vibration felt in the brake pedal. This is normal. Continue to steer the vehicle in the intended direction. When the light is on solid and the message(s), SERVICE ESC, ESC OFF, or both display, the system will not assist the driver in maintaining directional control of the vehicle. Adjust your driving accordingly. See DIC Warnings and Messages on page 3-42. The 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 cruise control is being used when ESC activates, the cruise control automatically disengages. The cruise control can be reengaged when road conditions allow. See Cruise Control on page 3-10. 4-6
