Instruments and controls Air distribution The air distribution control is used to direct the flow of air to the defroster, panel and floor vents. The control also permits settings in between the three main settings defroster, panel and floor: • defroster and floor • panel and floor • defroster, panel and floor (11 o'clock position) To counter cold drafts from the front side windows when the control has been set to defroster or floor, a small flow of air issues from the outer vents on the fascia. As the winter comfort setting, we recommend that the distribution knob be turned to . 99 Recommended settings in severe cold On starting with a cold engine, set the fan speed to 2 or 3 and select maximum heat and defroster to heat the cabin and demist the windshield as quickly as possible. When the engine is warmer and the temperature gauge starts to rise, fan setting 4 may be chosen. Once the windshield is clear, the air distribution control should be turned to . If the rear seat passengers desire more warmth to the feet, turn the distribution knob one step clockwise. How quickly the engine warms up will depend on how the car is driven. It will take longer for the engine to warm up if the car is driven in a high gear at low engine speeds, such as in town, than if it is driven at high engine speeds on a highway, for example. Do not use fan speed 5. This is primarily intended for rapid cooling during the summer.
