2001 Saab 9-5 Owner's Manual - Page 156

156 NOTE Starting and driving Fuel (Gasoline Engine) NOTE The engine control module (ECM) monitoring the engine parameters also stores fault codes. Under certain circumstances, this may cause constant illumination of the "Engine malfunction (CHECK ENGINE)" lamp , thus indicating a fault that must be checked by your Saab dealer. NOTE: always observe the following two measures: • Make sure that the fuel filler cap is screwed on correctly before the engine is started. Screw on the fuel filler cap until you hear 3 distinct clicks. • Avoid driving with the fuel low level indicator illuminated. The symbol illuminates when less than approximately 2 gallons (8 litres) of fuel remains in the tank. Use regular unleaded gasoline rated at 87 octane or higher. It is recommended that the gasoline meet specifications which were developed by the American Automobile Manufacturers Association (AAMA) and endorsed by the Canadian Motor Vehicle Manufacturers Association for better vehicle performance and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and emission control system performance compared to other gasolines. Higher concentrations of methanol than listed above, or the use of methanolblended gasoline without suitable co-solvents and corrosion inhibitors, can damage your car's fuel system, leading to the need for repairs which are not covered by Saab's product warranty. In Canada, look for the "Auto Makers' Choice" label on the fuel pump.
