134 Starting and driving • Never park the car on dry grass or other combustible material. The catalytic converter gets very hot and could therefore start a fire. • Never drive off if the engine is misfiring. • If you jump start the car when the engine is already up to normal temperature, the engine must start to run on all cylinders. Stop jump-starting if the engine fails to start immediately. To ensure that the catalytic converter continues to function properly, and also to avoid damage to the converter and its associated components, the following points must be observed: • Have the car serviced regularly in accordance with the service program. The fuel and ignition systems are particularly important in this context. • Always be alert to any misfiring of the engine (not running on all cylinders) and any loss of power or performance. At the first sign of a malfunction, reduce speed and take the car to an authorized Saab dealer as soon as possible. • If the engine fails to start (in very cold weather or if the battery is flat), the car can be jump started (manual gearbox only) or started using jump leads to a donor battery. However, as soon as you have started the engine, it is important that it runs on all cylinders. If it is misfiring, allow it to idle for up to five minutes to give it time to settle and run smoothly. If, after this time, the engine still fails to run properly, turn off the engine and get in touch with an authorized Saab dealer for advice. Refueling Always use the correct grade of fuel: unleaded AON 87-93. Saab recommends: • AON 90 for 4-cylinder engines • AON 93 for V6-engines and 2.3 Aero, (see page 228). If fuel containing a mixture of alcohol is used, the following restrictions apply: Methanol: max. 5% by volume. Ethanol: max. 10% by volume. MTBE: max. 15% by volume. The fuel filler cap is located in the right rear quarter panel. Switch off engine. Open fuel door Insert the fuel-pump nozzle beyond the flange on the filler pipe. Do not withdraw the nozzle while filling is in progress. Cease refuelling the first time the pump stops. NOTE If the car runs out of fuel, it is possible for air to get into the fuel system. If this happens, the catalytic converter may overheat and be damaged. Failure to follow these directions could result in the catalytic converter and associated components being damaged, and could represent a breach of the warranty conditions. V6 engine: When starting the engine from cold an electrical pump is activated. This pump pumps air into the exhaust system so that the catalytic converter will reach its normal operating temperature more rapidly. The pump is active for 30-60 seconds. NOTE Do not overfill. Fuel should not come right up the filler pipe as expansion room is needed. Fuel-tank capacity: 18.5 US gal. (70 liters) Screw on the filler cap and keep turning until it has clicked at least three times. The most effective way to prevent condensation forming in the tank (and thus avoid
