88 Instruments and controls ACC - 9-3 Convertible When the soft top is folded down the ACC system goes over to manual temperature setting. Between HI and LO there are eleven (0-10) fixed temperature steps. The system adjusts itself as follows • AUTO is turned off. • Heating, air distribution and fan speed are not affected. • Recirculation and electric rear window are turned off. • A/C assumes the same setting (ON/OFF) as it had when the soft top was last folded down. All manual selections are possible with the exception of electric rear window. Saab recommends leaving the ACC setting on ECON when the soft top is folded down to improve fuel economy and unnecessary running of the A/C compressor. When the soft top is raised the system reverts to the AUTO mode and the previous set temperature. Useful tips: If the ACC system is not functioning satisfactorily the following should be tried before you take the car to an authorized Saab dealer. • If the indication AUTO does not light up after starting (the ignition must have been switched off for at least 10 minutes): See Cancelling programming of ACC. • If you think that the ACC system is not functioning satisfactorily you should: 1. Check that the cigarette lighter plug is in its socket (since if the socket is empty heated air can flow out and affect the cabin sensor). 2. Recalibrate: See the section headed Calibration. • If the battery has been disconnected or has died, the ACC system should be recalibrated: See Calibration. Programmed settings are not deleted if the battery has been disconnected. ACC display with soft top folded down Extinguishing the lighting in ACC See section Night Panel, page 63. IB795
