WARNING
California Proposition 65
Operating, servicing and maintaining a pas-
senger vehicle can expose you to chemicals
including engine exhaust, carbon monoxide,
phthalates, and lead, which are known to the
State of California to cause cancer and birth
defects or other reproductive harm. To mini-
mize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, serv-
ice your vehicle in a well ventilated area and
wear gloves or wash your hands frequently
when servicing your vehicle. For more infor-
mation go to www.P65Warnings.ca.gov/

Volvo recommends the use of detergent gaso-
line to control engine deposits.
Deposit control gasoline (gasoline with
detergent additives)
Detergent gasoline is effective in keeping injec-
tors 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.
NOTE Volvo recommends not using external fuel
injector cleaning systems, e.g. do not add
detergent additives to gasoline before or after
refueling.
Unleaded fuelAll Volvo vehicles have a three-way catalytic con-
verter and must only use unleaded gasoline. 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 unlaw-
ful to dispense leaded fuel into a vehicle labeled
"unleaded gasoline only". Leaded gasoline dam-
ages the three-way catalytic converter and the
heated oxygen sensor system. Repeated use of
leaded gasoline will lessen the effectiveness ofthe 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 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 technician for service.
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 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 meet seasonal air quality standards,
some areas require the use of "oxygenated" fuel.

difference in engine operation is noticeable.
Fuel FormulationsDo not use gasoline that contains lead or manga-
nese as a knock inhibitor, and do not use lead
additives. Besides damaging the exhaust emis-
sion 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 strongly linked to
certain forms of cancer. If you live in an area
where you must fill your own gas tank, take pre-
cautions. These may include:

standing upwind away from the filler nozzle
while refueling
refueling only at gas stations with vapor
recovery systems that fully seal the mouth of
the filler neck during refueling
wearing neoprene gloves while handling a
fuel filler nozzle.
Use of AdditivesWith the exception of gas line antifreeze during
winter months, do not add solvents, thickeners, 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.
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 gaso-
line fumes, resulting in fire and injury.
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 com-
partment is ventilated, and immediately return
the vehicle to a trained and qualified Volvo
service technician for correction.
Demanding drivingIn demanding driving conditions, such as when
towing a trailer or driving in hot weather or for
prolonged periods at high altitudes, it may be a
good idea to switch to a higher-octane fuel (AKI
6
91 or higher) or to switch to another brand of
gasoline in order to fully utilize the vehicle's
engine capacity and optimize traction.

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 conditions, such as engine
overheating or backfiring. A properly tuned
engine will help avoid malfunctions that
could damage the three-way catalytic con-
verter.
Do not park your vehicle over combustible
materials, such as grass or leaves, which can
come into contact with the hot exhaust sys-
tem and cause such materials to ignite under
certain wind and weather conditions.
Excessive starter cranking (in excess of one
minute), or an intermittently firing or flooded
engine can cause three-way catalytic con-
verter or exhaust system overheating.
Remember that tampering or unauthorized
modifications to the engine, the Engine Con-
trol Module, or the vehicle may be illegal and
can cause three-way catalytic converter or
exhaust system overheating. This includes:
altering fuel injection settings or compo-
nents, altering emission system components or location or removing components, and/or
repeated use of leaded fuel.NOTE Unleaded fuel is required for vehicles with
three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen
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 combustion to help reduce
harmful emissions.

Fuel (p. 476) Overheating of engine and
transmission
In demanding driving conditions, such as driving
in mountainous areas or hot weather, there is a
risk of the engine or transmission overheating,
especially when carrying heavy loads.
Engine power may be temporarily limited.
Remove any auxiliary lights mounted in front
of the grille when driving in hot weather.
If the temperature in the engine's cooling
system becomes too high, a warning symbol
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.
If the message

If the transmission begins to overheat, an
alternative gear shifting program will be
selected. An integrated protective function
will also be activated, the warning symbol will
illuminate and the message Transmission
