VENTILATORS HEATER AND AIR CONDITIONER (manual) WARNING ● The air conditioner cooling function operates only when the engine is running. ● On hot, sunny days, temperatures in a closed vehicle could quickly become high enough to cause severe or possibly fatal injuries to people or animals. 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. WHA0223 Adjust air flow direction for the driver side 1 , center 2 , and passenger side 3 ventilators by moving the ventilator slide and/or ventilator assemblies. ● 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. ● Positioning of the heater and/or air conditioner controls should not be done while driving so full attention may be given to vehicle operation. 4-2 Heater, air conditioner and audio systems
