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 fuel
Each 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  labelled "UNLEADED".  Only these pumps have nozzles which  fit
your vehicle's filler  inlet. It is unlawful to dispense  leaded fuel into a  vehicle labelled "unleaded gasoline only".
Leaded  gasoline damages the three-way catalytic converter and  the heated oxygen  sensor system. Repeated use of
leaded gasoline will lessen  the effectiveness of the 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 lamp) located on your instrument panel may light. If this  occurs,
please return your vehicle to an  authorized Volvo retailer 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.
Volvo allows the use of the following "oxygenated" fuels; however,  the octane ratings listed on this  page must  still  be
met.
Alcohol - Ethanol: Fuels containing up to 10% ethanol  by volume may be  used. Ethanol may also be  referred to as
Ethyl alcohol,  or "Gasohol".
Ethers - MTBE: Fuels containing up to 15% MTBE may be  used.

- Remove the wheel cap (where applicable)  using the lug wrench  in the tool bag.
- With the vehicle still  on the ground, use the lug wrench  to loosen the wheel bolts  1/2 - 1 turn by exerting downward
pressure. Turn  the bolts  counterclockwise to loosen.CAUTION!
- The vehicle must  not be  driven with wheels of different  dimensions or with a  spare tire other than the one  that
came with the vehicle. The use of different  size wheels can seriously damage your vehicle's transmission.
- Correct tightening torque on wheel bolts  must  be  observed. The wheel bolts  should never be  greased or lubricated.
The extended, chromed wheel bolts  must  not be  used with steel rims, as they make it impossible to fit the hub caps.
- Locking wheel bolts  can be  used on both aluminum and  steel wheels. If hub caps are used on steel wheels, the
locking wheel bolt should be  mounted in the hole as far from  the tire's inflation valve as possible. It would otherwise
not be  possible to mount the hub cap on the wheel.
pg. 159 Wheels and tires
Changing wheels
- Position the jack correctly on the bar in the attachment (see illustration above) and  crank while simultaneously
guiding the base of the jack to the ground. The base of the jack must  be  flat on a  level,  firm, non-slippery surface.
Before raising the vehicle, check that the jack is still  correctly positioned in the attachment.
- Raise the vehicle until the wheel to be  changed is lifted off the ground.
- Unscrew the wheel bolts  completely  and  carefully remove the wheel so as not to damage the threads on the studs.
