Air for tires dispensed differently in Sweden
In the US, air is dispensed by an air hose. In Sweden, air is free. Usually there is a cabinet near one of the walls of the gas station, possibly marked "luft" or air.
There is a small canister similar in shape to a propane tank. It has a metal rod which the tank hangs to the recepticle. It also has a small rubber hose and a nozzle that fits to the tire valvestem. If you look carefully, you will see two buttons on the canister, marked + and -.
To add air, hold the nozzle very firmly to the valvestem. You will lose air if not held tightly. Then press the + button for about 1 second to add air. There is a warning not to hold it for more than one second so as not to risk overinflation.
The cannister only has enough air to fill one tire (or less). You have to refill the cannister with air by hanging the metal rod (not completely shown in the photo) back in the storage cabinet. The cabinet that I used had 2 cannisters so that you could recharge one as you used the second one.
SAAB recommends that you overinflate the tires to 43 psi before you store the car for long periods. Therefore, just before you return the car for transatlantic shipment, consider overfilling the tires to 43 psi. Consider bring a tire gauge with you on the trip.
For those of you returning the car to Gothenburg, the returning point is the Beko Bil car dealer in Askim. There is an automated, unmanned Shell station (Tankomatic) next to Beko Bil, but I did not see air there.
