Competitive Driving (CTS-V) When competitive driving mode is turned on with the TC (traction control) button, this message will be displayed on the DIC. The TC light will be on when the competitive driving mode is on. The Traction Control System (TCS) will not operate while in competitive driving mode. You should adjust your driving accordingly. See the CTS-V portion of Traction Control System (TCS) (CTS) on page 295 or Traction Control System (TCS) (CTS-V) on page 297 for more information. Engine Coolant Hot - AC (Air Conditioning) Off This message displays when the engine coolant becomes hotter than the normal operating temperature. To avoid added strain on a hot engine, the air conditioning compressor is automatically turned off. When the coolant temperature returns to normal, the air conditioning compressor will turn back on. You can continue to drive your vehicle. If this message continues to appear, have the system repaired by your dealer as soon as possible to avoid damage to the engine or transmission. Driver Door Ajar When this message appears on the display, it means that the driver's door was not closed completely. You should make sure that the driver's door is closed completely. 232
