Fuel requirements
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 a\
n average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON + MON/2). T\
he minimum octane
requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additive\
s. These additives have shown
to be effective 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 unleade\
d gasoline. U.S. and Canadian
regulations require that pumps delivering unleaded gasoline be labelled \
"UNLEADED". Only these
pumps have nozzles which fit your car's filler inlet. It is unlawful to \
dispense leaded fuel into a vehicle
labelled "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 co\
verage. State and local vehicle
inspection programs will make detection of misfueling easier, possibly r\
esulting in emission test failure
for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive ca\
lled methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, \
your Emission Control System
performance may be affected, and the Check Engine light (malfunction in\
dicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle t\
o an authorized Volvo retailer for
service.
Gasoline containing alcohol and ethers
"Oxygenated fuels"

Some fuel suppliers sell gasoline containing "oxygenates" which are usua\
lly alcohols or ethers. In some
areas, state or local laws require that the service pump be marked indic\
ating 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 operat\
or. 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 oc\
tane ratings listed on this page
must still be met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be used. Ethanol may al\
so be
referred to as Ethyl alcohol, or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be used.
CAUTION! Do not use gasolines 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.
pg. 85 Fuel requirements
Carbon Monoxide - Important Warning
Carbon monoxide is a poisonous, colorless, and odorless gas. It is prese\
nt in all exhaust gases. If you
ever smell exhaust fumes inside the vehicle, make sure the passenger com\
partment is ventilated, and
immediately return the vehicle to your retailer for correction.
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 car, lead has been\
strongly linked to certain
forms of cancer.
Many fuels contain benzene as a solvent. Unburned benzene has been stron\
gly linked to certain forms of
cancer. If you live in an area where you must fill your own gas tank, ta\
ke precautions. These may
include:
l standing upwind away from the filler nozzle while refueling
l refueling only at gas stations with vapor recovery systems that fully se\
al the mouth of the filler neck
during refueling
l wear neoprene gloves while handling a fuel filler nozzle.
Use of Additives

With the exception of gas line antifreeze during winter months, do not a\
dd solvents, thickeners, or other
store-bought additives to your car's fuel, cooling, or lubricating syste\
ms. Overuse may damage your
engine, and some of these additives contain organically volatile chemica\
ls. Do not needlessly expose
yourself to these chemicals.
pg. 86 Refueling
Refueling
The fuel tank holds approximately 18.5 US gals (70 liters) or 19 US ga\
ls (72 liters) on models equipped
with All Wheel Drive, with sufficient volume left over to accommodate po\
ssible expansion of the fuel in
hot weather. Be aware that the "usable" tank capacity will be somewhat l\
ess than the specified
maximum. When the fuel level is low, such factors as ambient temperature\
, the fuel's "Reid vapor
pressure" characteristics, and terrain can affect the fuel pump's abilit\
y 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.
Fuel filler door
Press the button on the light switch panel (see illustration on page 34) when the car is at a standstill to
unlock the fuel filler door. Please note that the fuel filler door will \
remain unlocked until the car begins
to move forward. An audible click will be heard when the fuel filler doo\
r relocks.
If you intend to leave your car while it is being refueled, this feature\
s enables you to lock the door/
tailgate while leaving the fuel filler door unlocked.
You can also keep the car locked if you remain inside it during refuelin\
g. The central locking button
does not lock the fuel filler door.
Be sure the fuel filler door is not obstructed and is completely closed \
after refueling. Open the fuel
filler cap slowly during hot weather conditions.

Volvo Cars recommends Castrol.
Depending on your driving habits, premium or synthetic oils may provide \
superior fuel economy and
engine protection. Consult your Volvo retailer for recommendations on pr\
emium or synthetic oils.
Oil additives must not be used.
NOTE: Synthetic oil is not used when the oil is changed at the normal maintena\
nce services. This oil is
only used at customer request, at additional charge. Please consult your\
Volvo retailer.
Oil viscosity (stable ambient temperatures)
Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when t\
emperatures do not exceed 86 °F
(30°C), SAE 5W/30 will provide good fuel economy and engine protect\
ion. See the viscosity chart
below.
Operation in hot climates
When temperatures exceed 86 °F (30°C) in your area, Volvo recomm\
ends, for the protection of your
engine, that you use a heavier weight oil, such as SAE 10W/30. See the v\
iscosity chart below.
Extreme engine operation
Synthetic oils meeting SAE 10W/30 and complying with oil quality require\
ments are recommended for
driving in areas of sustained temperature extremes (hot or cold), when\
towing a trailer over long
distances, and for prolonged driving in mountainous areas.
Changing oil and oil filter
Oil and oil filter changes should be made at 7,500 mile (12,000 km) in\
tervals.
The API Service Symbol
The API Service Symbol "donut" is divided into three parts:
