Simplest is to always have the A/C button pressed in. The A/C system will then cut in automatically when the outside temperature is high enough. Headlight aiming WARNING Before checking/adjusting the headlight aiming, switch off the engine to avoid danger of fingers and hands being injured by moving parts. The radiator fan can start up even when the engine is switched off. The vehicle has a visual optical headlight aiming system equipped with vertical aiming device. The aim has been preset at the factory and should normally not need further adjustments. If your headlights are damaged in a crash, the headlight aim may be affected. If you believe your headlights need to be reaimed, we recommend that you take it to your Saab dealer for service.

To check the aim, the vehicle should be properly prepared as follows: • The vehicle shall be placed so that the headlights are 25 ft (7.6 m) from a light colored wall or other flat surface. The aiming area should be darkened, this will improve your ability to see the beam of the low beam headlight being aimed. An optical headlamp aimer can also be used and will than replace the wall. • The vehicle must have all four wheels on a perfectly level surface which is level all the way to the wall or other flat surface. • The vehicle should be placed so it is perpendicular to the wall or other flat surface. • The vehicle should be unloaded and fuel tank full, and one person or 160 lbs. (75 kg) on the drivers seat. • The vehicle should be fully assembled and all other work stopped while headlight aiming is being done. • The vehicle should not have any snow, ice or mud attached to it. • Tires should be inflated to the prescribed pressure. • Close all doors. • Rock the vehicle to stabilize the suspension.
