Manual transmission The following speeds should not be exceeded during the break-in period: Up to 600 miles 600 - 1,200 miles (1000 km) (1000 - 2000 km) 1st gear 20 mph (30 km/h) 25 mph (40 km/h) 2nd gear 30 mph (50 km/h) 40 mph (70 km/h) 3rd gear 45 mph (80 km/h) 65 mph (100 km/h) 4th gear 70 mph (110 km/h) 80 mph (130 km/h) 5th gear/overdrive 80 mph (130 km/h) 95 mph (150 km/h) Posted speed limits should not be exceeded. Deposit control gasoline (detergent additives) Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with the service station operator. Unleaded Fuel Each Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. and Canadian regulations require that pumps delivering unleaded gasoline be labeled "UNLEADED". Only these pumps have nozzles which fit your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "unleaded gasoline only". Leaded gasoline damages the three-way catalytic converter and the heated oxygen sensor system. Repeated use of leaded gasoline will lessen the effectiveness of the emission control system and could result in loss of emission warranty coverage. State and local vehicle inspection programs will make detection of misfueling easier, possibly resulting in emission test failure for misfueled vehicles. NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive called methyl-cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected, and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your vehicle to an authorized Volvo retailer for service. pg. 57 Fuel requirements, Refueling Octane Rating Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91, or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane Number, MON, (RON + MON/ 2). The minimum octane requirement is AKI 87 (RON 91). Gasoline containing alcohol and ethers "Oxygenated fuels" 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 alcohol 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 restrictions, some states require the use of "oxygenated" fuel in certain areas. Volvo allows the use of the following "oxygenated fuels; however, the octane ratings listed on this page must still be met. Alcohol - Ethanol
