THE 9-3'S standard heating/air conditioning system is manually operated and incorporates a pollen filter. The 9-3 uses rotary switches for temperature, air direction and fan speed. A separate button is provided to recirculate the air inside the car. The airflow capacity of the system was improved with the introduction of the 9-3. Headlights can be adjusted from the instrument panel.

Rear-view mirrors are heated for better winter vision. The 9-3's air-conditioning compressor has better performance than that of the 900, particularly at low speed and when the engine is idling.
