This is normal and does not mean there is a problem with your 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 will be on solid, and the ESC OFF or SERVICE ESC message will be displayed. For more information, see Driver Information Center (DIC) on page 145 and Electronic Stability Control (ESC)/Traction Control System (TCS) Indicator/Warning Light (2.0L Engine Only) on page 136. This light will flash on the instrument panel cluster when the ESC system is both on and activated. When the light is on solid and either the SERVICE ESC or ESC OFF message is displayed, 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 148. See Electronic Stability Control (ESC)/Traction Control System (TCS) Indicator/Warning Light (2.0L Engine Only) on page 136 for more information. The Electronic Stability Control (ESC) system is automatically enabled whenever you start your vehicle. To assist the driver with vehicle directional control, especially in slippery road conditions, you should always leave the system on. But, you can turn ESC off if you ever need to. 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. When road conditions allow you to use cruise again, you may re-engage the cruise control. See Cruise Control on page 115. You may also feel or hear the system working; this is normal. 201
