SERVICE AND MAINTENANCE
Demanding driving
In demanding driving conditions, such as
operating the vehicle in hot weather, towing a
trailer, or driving for extended periods at higher
altitudes than normal, it may be advisable to
switch to higher octane fuel (91 or higher) or
to change gasoline brands to fully utilize your
engine’s capacity, and for the smoothest possible
operation.
NOTE
When switching to higher octane fuel or
changing gasoline brands, it may be necessary
to fill the tank more than once before a
difference in engine operation is noticeable.
Fuel FormulationsDo 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 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 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.
WARNING
California Proposition 65
Operating, servicing and maintaining a
passenger 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
minimize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, service
your vehicle in a well ventilated area and wear
gloves or wash your hands frequently when
servicing your vehicle. For more information
go to www.P 65Warnings.ca.gov/passenger-
vehicle.
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
gasoline 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 compartment
is ventilated, and immediately return the
vehicle to a trained and qualified Volvo service
technician for correction.
Deposit control gasoline (detergent
additives)
Volvo recommends the use of detergent gasoline
to control engine deposits. Detergent gasoline
is effective in keeping injectors and intake valves
clean. Consistent use of deposit control gasolines
will help ensure good drivability and fuel economy.
If you are not sure whether the gasoline contains
deposit control additives, check with the service
station operator.
NOTE
Volvo does not recommend the use of external
fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter
and must use only unleaded gasoline. U.S. and
Canadian regulations require that pumps delivering
unleaded gasoline be labeled “UNLEADED”. Only
these pumps have nozzles which fit your vehicle’s
filler inlet. It is unlawful to dispense leaded fuel
into a vehicle labeled “unleaded gasoline only”.
Leaded gasoline damages the threeway catalytic
converter and the heated oxygen sensor system.
Repeated use of leaded gasoline will lessen the
