lessen the effectiveness of the emission con-

trol system and could result in loss of emission

meet seasonal air quality standards, some

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".

NOTE

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.

NOTE

Volvo recommends not using external fuel

injector cleaning systems, e.g. do not add

detergent additives to gasoline before or

after refueling.

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".

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

NOTE

Volvo requires premium fuel (91 octane¹⁹or

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:

zle while refueling

may be a good idea to switch to a higher-

octane fuel (AKI¹⁹91 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-

Demanding driving

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.

•

NOTE

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.

NOTE

It is normal for the engine's cooling fan to

operate for a short time after the engine is

switched off.
