2004 VOLVO S40 fuel consumption

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 car'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 Lamp located on your instrument panel may light. If this occurs, please return your vehicle to
an authorized Volvo retailer for service.
Carbon Monoxide - Important 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.
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 car, 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
wear 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 car'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.
ENGINE OIL
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearing in to each other. From the time the engine is new until
the first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
important to check the oil every time you refuel your car during this period. See page 114

pg. 63 Fuel requirements, Refueling
Octane rating
Volvo engines are designed for optimum performance on unleaded premium gasoline with an octane rating. AKI of 91,
or above. AKI (ANTI KNOCK INDEX) is an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).
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

Do not exceed posted speed limits.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (check when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that roof racks, ski racks, etc., increase air resistance and thereby fuel consumption.
Avoid using automatic transmission kick-down feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
Utilizing the fuel consumption modes in the Trip Computer can help you "learn" how to drive more economically.
Other factors which decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard Maintenance Service intervals.
NOTE : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of
snow tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
Do not drive with trunk lid open! A warning light in the instrument panel will indicate that the trunk is open.
Poisonous exhaust gases may enter via the open trunk lid. If the trunk lid/tailgate must be kept open for any reason,
proceed as follows:
Close the windows.
Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.
pg. 65 Starting the engine
Starting and stopping
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Make sure the gear selector is in the Park position.
3. Without touching the accelerator pedal, turn the ignition key to the starting position. Allow the starter to operate
for up to 5 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts. Depress the brake pedal and release the parking
brake.
