lished by leading automotive manufactures to
meet the needs of today's advanced engines.
Qualifying gasoline retailers (stations) will, in
most cases, identify their gasoline as having met
the "TOP TIER Detergent Gasoline" standards.
NOTE
Information about TOP TIER Detergent Gaso-
line is available at www.toptiergas.com.
Demanding driving
In demanding driving conditions, such as operat-
ing 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 opera-
tion.
NOTE
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 noticeable.
Fuel Formulations
Do not use gasoline that contains lead as a
knock inhibitor, and do not use lead additives.
AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number (RON) and the Motor Octane Number (MON), MON+RON/2.

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 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 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.
STARTING AND DRIVING
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.
