126 Instruments and Controls Warning Lights, Gauges, and Indicators Warning lights and gauges can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gauges could prevent injury. Some warning lights come on briefly when the engine is started to indicate they are working. When one of the warning lights comes on and stays on while driving, or when one of the gauges shows there may be a problem, check the section that explains what to do.

Climate Controls 185 Service All vehicles have a label underhood that identifies the refrigerant used in the vehicle. The refrigerant system should only be serviced by trained and certified technicians. The air conditioning evaporator should never be repaired or replaced by one from a salvage vehicle. It should only be replaced by a new evaporator to ensure proper and safe operation. During service, all refrigerants should be reclaimed with proper equipment. Venting refrigerants directly to the atmosphere is harmful to the environment and may also create unsafe conditions based on inhalation, combustion, frostbite, or other health-based concerns. The air conditioning system requires periodic maintenance. See Maintenance Schedule 0 383. Chevrolet Tahoe/Suburban Owner Manual (GMNA-Localizing-U.S./Canada/ Mexico-13566622) - 2020 - CRC - 4/24/19
