areas require the use of "oxygenated" fuel.
Fuel
Volvo recommends the use of detergent gas-
oline to control engine deposits.
Volvo permits the use of the following "oxy-
genated" fuels. However, the specified octane
ratings must still be met.
Deposit control gasoline (gasoline
with detergent additives)
Alcohol - Ethanol
Detergent gasoline is 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 serv-
ice station operator.
Fuels containing up to 10% ethanol by volume
may be used. Ethanol may also be referred to
as Ethyl alcohol, or "Gasohol".
Some U.S. and Canadian gasolines contain
an octane enhancing additive called
methyl-cyclopentadienyl manganese tricar-
bonyl (MMT). If such fuels are used, your
Emission Control System performance
may be affected, and the Check Engine
Light (malfunction indicator light) located
on your instrument panel may light. If this
occurs, please return your vehicle to a
trained and qualified Volvo service techni-
cian for service.
Ethers - MTBE/ETBE: Fuels containing up to
22% MTBE/ETBE by volume may be used.
Methanol
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 sys-
tem. Such damage may not be covered under
the New Vehicle Limited Warranty.
Volvo recommends not using external fuel
injector cleaning systems, e.g. do not add
detergent additives to gasoline before or
after refueling.

Unleaded fuel
•
Gasoline containing alcohol and
ethers, "Oxygenated fuels"
All Volvo vehicles have a three-way catalytic
converter and must only use unleaded gaso-
line. US and Canadian regulations require that
pumps delivering unleaded gasoline are
labeled "UNLEADED". Only the nozzles of
these pumps will fit in your vehicle's fuel filler
inlet. It is unlawful to dispense leaded fuel into
a vehicle labeled "unleaded gasoline only".
Leaded gasoline damages the three-way cata-
lytic converter and the heated oxygen sensor

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 indi-
cating 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

Octane rating
Volvo requires premium fuel (91 octane19 or
higher) for all T5, T6 and T8 engines, and rec-
ommends AKI 93 for optimal performance
and fuel economy. See decal examples in
illustrations 1 and 2.
When switching to higher octane fuel or
changing gasoline brands, it may be neces-
sary to fill the tank more than once before a
difference in engine operation is noticea-
ble.

Do not use gasoline that contains lead or man-
ganese 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.
.
TOP TIER Detergent Gasoline
Volvo endorses the use of "TOP TIER Deter-
gent Gasoline" where available to help main-
tain engine performance and reliability. TOP
TIER Detergent Gasoline meets a new stand-
ard jointly established by leading automotive
manufactures to meet the needs of today's
advanced engines. Qualifying gasoline retail-
ers (stations) will, in most cases, identify their
gasoline as having met the "TOP TIER Deter-
gent Gasoline" standards.
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 noz-
zle while refueling

may be a good idea to switch to a higher-
octane fuel (AKI19 91 or higher) or to switch to
another brand of gasoline in order to fully uti-
lize the vehicle's engine capacity and optimize
traction.
Use of Additives
Emission controls
With the exception of gas line antifreeze dur-
ing winter months, do not add solvents, thick-
eners, 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.
Three-way catalytic converter
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if you
detect engine misfire, noticeable loss of
power or other unusual operating condi-
tions, such as engine overheating or back-
firing. A properly tuned engine will help
avoid malfunctions that could damage the
three-way catalytic converter.

WARNING
Never carry a cell phone that is switched
on while refueling your vehicle. If the
phone rings, this may cause a spark that
could ignite gasoline fumes, resulting in fire
and injury.
Do not park your vehicle over combustible
materials, such as grass or leaves, which
can come into contact with the hot
exhaust system and cause such materials
to ignite under certain wind and weather
conditions.
•
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 immedi-
ately return the vehicle to a trained and
qualified Volvo service technician for cor-
rection.
Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cata-
lytic converter or exhaust system over-
heating.
•
•
Remember that tampering or unauthor-
ized modifications to the engine, the
Engine Control Module, or the vehicle may
be illegal and can cause three-way cata-
lytic converter or exhaust system over-

recommendations given by reducing
speed or stopping the vehicle safely and
letting the engine idle for a few minutes to
let the transmission cool.
Overheating of engine and
transmission
In certain driving conditions, such as driving
in mountainous areas or hot weather, there is
a risk of the engine or transmission overheat-
ing, especially when carrying heavy loads.
If the vehicle begins to overheat, the air
conditioning may be temporarily switched
off.
•
•
Engine power may be temporarily limited.
•
Remove any auxiliary lights mounted in
front of the grille when driving in hot
weather.
Unleaded fuel is required for vehicles with
three-way catalytic converters.
•
After a prolonged period of driving in
demanding conditions, do not turn off the
engine immediately after stopping.
If the temperature in the engine's cooling
system becomes too high, a warning sym-
bol will appear in the instrument panel
along with the message Engine
temperature High temperature Stop
safely. Pull over to a safe location and let
the engine idle for a few minutes to cool
down.
•
Heated oxygen sensors
The heated oxygen sensors monitor the oxy-
gen content of the exhaust gases. Readings
are fed into a control module that continuously
monitors engine functions and controls fuel
injection. The ratio of fuel to air into the engine
is continuously adjusted for efficient combus-
tion to help reduce harmful emissions.
It is normal for the engine's cooling fan to
operate for a short time after the engine is
switched off.
