THE Zafira's standard air-conditioning system was designed to suit Australian climatic conditions and was thoroughly tested by Opel and Holden engineers in northern and central Australia. The HVAC system uses rotary dials for fan speed, temperature and air distribution, plus buttons for air-conditioning, recirculation and rear demist. A pollen filter and vents in the front and second row are provided. Zafira also features a heat reflective windshield that contains a tinted metallic foil between two layers of laminated glass and reflects radiation back outside. Holden claims the screen increases solar energy reflection by 28 per cent over a conventional windshield up to 58.5 per cent of solar energy is reflected.
