Check Engine Light (malfunction indicator lamp) located on your instrument panel may light. If this occurs, please return your vehicle to a trained and qualified Volvo service technician for maintenance. Gasoline containing alcohol and ethers Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols or ethers. In some areas, state or local laws require that the service pump be marked indicating use of alcohols or ethers. However, there are areas in which the pumps are unmarked. If you are not sure whether there is alcohol or ethers in the gasoline you buy, check with the service station operator. To meet seasonal air quality standards, some areas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxygenated" fuels; however, the octane ratings listed on this page must still be met. Alcohol - Ethanol Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to as Ethyl alcohol, or "Gasohol". Ethers - MTBE: Fuels containing up to 15% MTBE may be used. Fuel Formulations Do not use gasoline that contains lead as a knock inhibitor, and do not use lead additives. Besides damaging the exhaust emission control systems on your vehicle, lead has been strongly linked to certain forms of cancer. Many fuels contain benzene as a solvent. Unburned benzene has been strongly linked to certain forms of cancer. If you live in an area where you must fill your own gas tank, take precautions. These may include: standing upwind away from the filler nozzle while refueling refueling only at gas stations with vapor recovery systems that fully seal the mouth of the filler neck during refueling wearing neoprene gloves while handling a fuel filler nozzle. WARNING Carbon monoxide is a poisonous, colorless, and odorless gas. It is present in all exhaust gases. If you ever smell exhaust fumes inside the vehicle, make sure the passenger compartment is ventilated, and immediately return the vehicle to a trained and qualified Volvo service technician for correction. Use of Additives With the exception of fuel line antifreeze during winter months, do not add solvents, thickeners, or other store-bought additives to your vehicle's fuel, cooling, or lubricating systems. Overuse may damage your engine, and some of these additives contain organically volatile chemicals. Do not needlessly expose yourself to these chemicals. Fuel filler door Press the button on the light switch panel (see the illustration on page 59) with the ignition switched off to unlock the fuel filler door. Please note that the fuel filler door will remain unlocked until the vehicle begins to move forward. An audible click will be heard when the fuel filler door relocks. 134 06 Starting and driving Fuel requirements
