Do not leave children or adults who would normally require the support of others in your vehicle. Unattended pets should not be left alone either. ● Do not use the recirculation mode for long periods as it may cause the interior air to become stale and the windows to fog up. This mode may be normally used all year round as the system automatically works to keep a constant temperature. Air flow distribution and fan speed are also controlled automatically. 1. Turn the fan control dial to the AUTO position. 2. Turn the temperature dial to the left or right to set the desired temperature. ● Adjust the temperature dial to about 75°F (25°C) for normal operation. 3. Turn the air flow control dial to AUTO. ● The temperature of the passenger compartment will be maintained automatically. ● Air flow distribution and fan speed are also controlled automatically. ● The air conditioner cooling function operates only when the engine is running. 4-20 Display screen, heater, air conditioner and audio systems
