Refueling
ENGINE OIL
Although some oil consumption occurs during normal engine operation, mor\
e oil is consumed when the
engine is new as the internal parts generate higher friction while weari\
ng-in to each other. From the time
the engine is new until the first maintenance is performed, the oil cons\
umption could be higher than
normal. For this reason, it is especially important to check the oil eve\
ry time you refuel your vehicle
during this period. See
page 149.
Fuel requirements
Octane rating
Volvo engines are designed for optimum performance on unleaded premium g\
asoline with an AKI
octane rating 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).
Deposit control gasoline (detergent additives)
Volvo recommends the use of detergent gasoline to control engine deposit\
s. Detergent gasoline is
effective in keeping injectors and intake valves clean. Consistent use o\
f deposit control gasolines will
help ensure good driveability and fuel economy. If you are not sure whet\
her the gasoline contains
deposit control additives, check with the service station operator.
NOTE: Volvo does not recommend the use of external fuel injector cleaning syst\
ems.
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 vehicle's filler inlet. It is unlawful\
to dispense leaded fuel into a
vehicle labelled "unleaded gasoline only". Leaded gasoline damages the t\
hree-way catalytic converter
and the heated oxygen sensor system. Repeated use of leaded gasoline wil\
l lessen the effectiveness of
the emission control system and could result in loss of emission warrant\
y coverage. State and local
vehicle inspection programs will make detection of misfueling easier, po\
ssibly resulting 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
maintenance.

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 o\
ctane ratings listed on this page
must still be met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol by volume may be u\
sed. Ethanol may also be
referred to as Ethyl alcohol, or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be used.
pg. 87 Starting and driving
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 vehicle, 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 wearing 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 vehicle's fuel, cooling, or lubricating s\
ystems. Overuse may damage your

engine, and some of these additives contain organically volatile chemica\
ls. Do not needlessly expose
yourself to these chemicals.
pg. 88 Starting and driving
Fuel filler door
Press the button on the light switch panel (see illustration on
page 29) when the vehicle is at a standstill
to unlock the fuel filler door. Please note that the fuel filler door wi\
ll remain unlocked until the vehicle
begins to move forward. An audible click will be heard when the fuel fil\
ler door relocks.
If you intend to leave your vehicle while it is being refueled, this fea\
ture enables you to lock the doors/
tailgate while leaving the fuel filler door unlocked.
You can also keep the vehicle locked if you remain inside it during refu\
eling. 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.
NOTE: During a transitional period, a small number of service stations may st\
ill have fuel nozzles that
are not compatible with the fuel filler neck on vehicles equipped with t\
he evaporative control system.
Refueling
Fuel tank capacity:
The fuel tank's capacity is 21.1 US gals. (80 liters) with sufficient \
volume left over to accommodate
possible expansion of the fuel in hot weather. Be aware that the "usable\
" tank capacity will be somewhat
less than the specified maximum. When the fuel level is low, such factor\
s as ambient temperature, the
fuel's "Reid vapor pressure" characteristics, and terrain can affect the\
fuel pump's ability to supply the

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 when the normal mainte\
nance is carried out.
This oil is only used at customer request, at additional charge. Please \
consult your Volvo retailer.
Oil Viscosity
Operation in hot climates.
For the protection of your engine when temperatures in your area exceed \
86° F (30° C), Volvo
recommends that you use an oil with suitable viscosity, as shown in the \
chart below.
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 protec\
tion. See the viscosity chart
above.
Extreme engine operation
Synthetic oils meeting ACEA A5/B5 requirements are recommended for drivi\
ng in areas of sustained
temperature extremes (hot or cold), when towing a trailer over long di\
stances, and for prolonged driving
in mountainous areas.

l The API Service Symbol "donut" is divided into three parts:
l The upper section describes the oil's performance level.
l The center identifies the oil's viscosity.
l The lower section indicates whether the oil has demonstrated energy-cons\
erving properties in a
standard test in comparison to a reference oil.
pg. 149 Maintenance
Changing engine oil and oil filter
See the previous page for oil specifications and
page 176 for oil volumes. Refer to the Warranty and
Service Records Information booklet for information on the oil change in\
tervals.
NOTE:
l Volvo does not recommend the use of oil additives.
l Synthetic oil is not used when the oil is changed at the normal maintena\
nce intervals except at ower
request and at additional charge. Please consult your Volvo retailer.
Checking and adding oil
The oil level should be checked every time the vehicle is refueled. This\
is especially important during
the period up to the first scheduled maintenance service.
l The car should be parked on a level surface when the oil is checked.
l If the engine is warm, wait for at least 10-15 minutes after the engine has been switched off\
before
checking the oil.
Checking the oil
1. Pull out the dipstick and wipe it with a lintfree rag.
