2007 Volvo V70
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 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 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.
Use of Additives
With 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 your retailer for correction.
