NOTICE

NOTICE

  • The refrigerant system should only be serviced by trained and certified technicians to insure proper and safe operation.
  • The refrigerant system should be serviced in a well-ventilated place.
  • The air conditioning evaporator (cooling coil) shall never be repaired or replaced with one removed from a used or salvaged vehicle and new replacement MAC evaporators shall be certified (and labeled) as meeting SAE Standard J2842.

NOTICE

  • When using the air conditioning system, monitor the temperature gauge closely while driving up hills or in heavy traffic when outside temperatures are high.

    Air conditioning system operation may cause engine overheating.

    Continue to use the fan but turn the air conditioning system off if the temperature gauge indicates engine overheating.

  • When opening the windows in humid weather air conditioning may create water droplets inside the vehicle.

    Since excessive water droplets may cause damage to electrical equipment, air conditioning should only be used with the windows closed.

Air conditioning system operation tips

  • If the vehicle has been parked in direct sunlight during hot weather, open the windows for a short time to let the hot air inside the vehicle escape.
  • After sufficient cooling has been achieved, switch back from the recirculated air to the fresh outside air position.
  • To help reduce moisture inside of the windows on rainy or humid days, decrease the humidity inside the vehicle by operating the air conditioning system with the windows and sunroof closed.
  •  Use the air conditioning system every month for a few minutes to ensure maximum system performance.
  • If you operate the air conditioner excessively, the difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up, causing loss of visibility. In this case, set the mode selection knob to the speed position and set the fan speed control knob to the lowest speed setting.
