Ignition OFF

WARNING: This page is about a different car, the 2006 Saab 9-5. However, it is still accessible from the selected car via links, so may be relevant.

When the ignition is turned off, the display goes out: no buttons work, all the stepping motors are turned off and air recirculation off is selected after 10 seconds. Diagnostics communication remains active if it was active when the ignition was turned off, but it cannot be restarted.

When approximately 8 minutes has passed, the air distribution damper moves to the floor position, 50% during cold weather and to ventilation position 0% during hot weather. The air-blending flap moves to max. cold position 0%. After 10 minutes the ACC control module moves down in energy-saving mode and the processor activates briefly every 4 minutes. This will continue for a further 110 minutes. Within this time (2 hours) the ACC control module can read the parameters and calculate the conditions for a good environment in the car's cabin.

If the ignition is switched on within these 120 minutes the control module will keep the manual options that may have been selected during the previous operation.

After 120 minutes the control module starts in AUTO mode or without user programmed mode.
