CLEAN RADAR When this message displays, it means that the Adaptive Cruise Control (ACC) system and the Forward Collision Alert (FCA) system are disabled because the radar is blocked and cannot detect vehicles in your path. It may also activate during heavy rain or due to road spray. To clean the system, see "Cleaning the System" under Adaptive Cruise Control on page 3-19. DRIVER DOOR OPEN This symbol appears with this message. CRUISE SET TO XXX MPH (km/h) This message will display whenever the cruise control is set. See Cruise Control on page 3-16 and Adaptive Cruise Control on page 3-19 for more information. If your vehicle has Adaptive Cruise Control (ACC), after a few seconds, this message will clear and the message "SET SPD XX" will display at the bottom of the DIC. See "SET SPD (Speed)" later in this section. This message will display when the driver's door is not closed completely. You should make sure that the driver's door is closed completely. ENGINE HOT - A/C (Air Conditioning) OFF This message will display when the engine coolant becomes hotter than the normal operating temperature. See Engine Coolant Temperature Gage on page 3-65. To avoid added strain on a hot engine, the air conditioning compressor automatically turns 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 GM dealer as soon as possible to avoid damage to your engine. 3-78
