Manual transmission
The following speeds should not be exceeded during the break-in period: Up to 600 miles
(1000 km)600 - 1,200 miles
(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
ProCarManuals.com

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.
Refueling
The fuel filler cap is located inside the fuel tank cover on the right rear fender.
NOTE: The fuel tank cover is locked and must be popped open using the control on the driver's door (see page 37).

Open fuel filler cap slowly during hot weather conditions.
When filling, hang the cap on the special bracket on the inside of the fuel tank cover.
NOTE: Turn the ignition off or to position I when refueling. If the ignition is on, an incorrect reading could occur in
the fuel gauge (low fuel level will be indicated).
After filling the tank, install the cap and turn until a "click" is heard.
The fuel tank is designed to hold approximately 18.4 US gal. (70 liters) with sufficient volume left over to
accommodate possible expansion of the fuel in hot weather. Be aware that the "usable" tank will be somewhat less than
the specified maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate supply of fuel.
Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the fuel warning
light comes on.
CAUTION:
Do not refuel with the engine running. After refueling, close the fuel filler cap by turning it clockwise until it
clicks into place.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
NOTE: If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Malfunction
Indicator Lamp may indicate a fault. Use only Volvo original or approved fuel filler caps.
CAUTION: Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted
surfaces, which may not be covered under the New Vehicle Limited Warranty.
Do not use gasoline containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under
the New Vehicle Limited Warranty.
