Starting and driving 147 Refueling WARNING Gasoline fumes are highly explosive. Therefore: • never smoke while refueling • never use gasoline for any purpose other than as engine fuel • gasoline is extremely flammable and can cause severe burns. No open or exposed flames near gasoline • do not use a mobile phone at the same time as refueling Only use fuel from a well-known oil company. All Saab gasoline engines can be driven on gasoline with an octane rating between AON 87-93. The engine management system monitors the combustion and automatically adapts to the fuel used. Always use the correct grade of fuel: unleaded AON 87-93. For optimum performance Saab recommends: • 2.0t engine 175 hp - AON 90. • 2.0 Turbo engine 210 hp - AON 90. Sometimes, gasoline can contain a number of additives containing oxygen. The most common of these are alcohol or some type of ether. The maximum oxygen level is restricted by national regulations. If fuel containing a mixture of alcohol is used, the maximum levels approved by Saab are: 5 % by volume of methanol; or 10 % by volume of ethanol. The most common type of ether used is MTBE (methyl tertiary butyl ether), of which fuel may contain a maximum of 15 % by volume. NOTICE • Do not overfill. Fuel should not come right up the filler pipe as room for expansion is needed for when the temperature rises. • The use of fuel with too low an octane rating can cause serious engine damage. Refueling 1 Switch off the engine. 2 Open the filler cap, located in the righthand rear fender. 3 Insert the fuel pump nozzle beyond the flange on the filler pipe and let the first mark (a ring, a pimple or the first springcoil) rest on the flange. Do not withdraw the nozzle while filling is in progress. 4 Cease refueling the first time the pump stops.
