UNDERSTANDING YOUR INSTRUMENT PANEL 125 • Defrost/Floor Air is directed through the windshield defrost and the floor outlets. This setting works best in cold or snowy conditions that require extra heat at the windshield. This setting is good for maintaining comfort while reducing moisture on the windshield. • Defrost Air is directed through the windshield defrost outlet. Use this mode with maximum fan and temperature settings for best windshield defrosting. NOTE: The air conditioning compressor operates in this mode. This dehumidifies the air to help dry the windshield. To improve fuel economy, leave in the Defrost mode only when necessary. Air Conditioning Control With the fan control in the ON position, push the A/C button to turn on the air conditioning compressor. An indicator light above the button shows that the Air Conditioning compressor is on. Conditioned air is now directed through the outlets selected. Pushing the button a second time turns the compressor OFF. Slight changes in engine speed or power may be noticed when the compressor is on. This is a normal occurrence since the compressor will cycle on and off to maintain comfort and increase fuel economy. NOTE: If your air conditioning performance seems lower than expected, check the front of the A/C condenser for an accumulation of dirt or insects. 4
