Volvo and the environment Volvo is committed to the well-being of its cus- tomers. As a natural part of this commitment, wecare about the environment in which we all live.Concern for the environment means an everydayinvolvement in reducing our environmentalimpact.
Volvo's environmental activities are based on a holistic view, which means we consider the over-all environmental impact of a product throughoutits complete life cycle. In this context, design, pro-duction, product use, and recycling are all impor-tant considerations. In production, Volvo haspartly or completely phased out several chemicalsincluding CFCs, lead chromates, asbestos, andcadmium; and reduced the number of chemicalsused in our plants 50% since 1991. Volvo was the first in the world to introduce into production a three-way catalytic converter with aLambda sond, now called the heated oxygen sen-sor, in 1976. The current version of this highlyefficient system reduces emissions of harmfulsubstances (CO, HC, NOx) from the exhaust pipeby approximately 95 – 99% and the search toeliminate the remaining emissions continues.Volvo is the only automobile manufacturer tooffer CFC-free retrofit kits for the air conditioningsystem of all models as far back as the 1975model 240. Advanced electronic engine controlsand cleaner fuels are bringing us closer to ourgoal. In addition to continuous environmental refinement of conventional gasoline-poweredinternal combustion engines, Volvo is activelylooking at advanced technology alternative-fuelvehicles. When you drive a Volvo, you become our partner in the work to lessen the car's impact on theenvironment. To reduce your vehicle's environ-mental impact, you can:
• Maintain proper air pressure in your tires.Tests have shown decreased fuel economywith improperly inflated tires.
• Follow the recommended maintenanceschedule in your Warranty and ServiceRecords Information booklet.
• Drive at a constant speed whenever possible.
• See a trained and qualified Volvo servicetechnician as soon as possible for inspectionif the check engine (malfunction indicator)light illuminates, or stays on after the vehiclehas started.
• Properly dispose of any vehicle-related wastesuch as used motor oil, used batteries, brakepads, etc.
• When cleaning your vehicle, please use gen-uine Volvo car care products. All Volvo carcare products are formulated to be environ-mentally friendly.

Fuel Volvo recommends the use of detergent gaso- line to control engine deposits.
Deposit control gasoline (detergentadditives)
Detergent gasoline is effective in keeping injec- tors and intake valves clean. Consistent use ofdeposit control gasolines will help ensure gooddrivability and fuel economy. If you are not surewhether the gasoline contains deposit controladditives, check with the service station operator.
NOTE
Volvo does not recommend the use of exter- nal fuel injector cleaning systems.
Unleaded fuelEach Volvo has a three-way catalytic converter and must use only unleaded gasoline. U.S. andCanadian regulations require that pumps deliver-ing unleaded gasoline be labeled "UNLEADED".Only these pumps have nozzles which fit yourvehicle's filler inlet. It is unlawful to dispense lea-ded fuel into a vehicle labeled "unleaded gaso-line only". Leaded gasoline damages the three-way catalytic converter and the heated oxygensensor system. Repeated use of leaded gasolinewill lessen the effectiveness of the emission con-trol system and could result in loss of emissionwarranty coverage. State and local vehicle inspection programs will make detection of mis-fueling easier, possibly resulting in emission testfailure 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 EmissionControl System performance may be affected,and the Check Engine Light (malfunctionindicator light) located on your instrumentpanel may light. If this occurs, please returnyour vehicle to a trained and qualified Volvoservice technician for service.
Gasoline containing alcohol and ethers, "Oxygenated fuels"
Some fuel suppliers sell gasoline containing "oxygenates" which are usually alcohols orethers. In some areas, state or local laws requirethat the service pump be marked indicating useof alcohols or ethers. However, there are areas inwhich the pumps are unmarked. If you are notsure whether there is alcohol or ethers in thegasoline you buy, check with the service stationoperator. To meet seasonal air quality standards,some areas require the use of "oxygenated" fuel. Volvo allows the use of the following "oxygen- ated" fuels; however, the octane ratings listedmust still be met.
Alcohol – Ethanol
Fuels containing up to 10% ethanol by volume may be used. Ethanol may also be referred to asEthyl alcohol, or "Gasohol". Ethers – MTBE: Fuels containing up to 15% MTBE may be used.
MethanolDo not use gasolines containing methanol(methyl alcohol, wood alcohol). This practice canresult in vehicle performance deterioration andcan damage critical parts in the fuel system. Suchdamage may not be covered under the NewVehicle Limited Warranty.

Emission controls
Three-way catalytic converter
•Keep your engine properly tuned. Certain engine malfunctions, particularly involving theelectrical, fuel or distributor ignition systems,may cause unusually high three-way catalyticconverter temperatures. Do not continue tooperate your vehicle if you detect enginemisfire, noticeable loss of power or otherunusual operating conditions, such as engineoverheating or backfiring. A properly tunedengine will help avoid malfunctions thatcould damage the three-way catalytic con-verter.
• Do not park your vehicle over combustiblematerials, such as grass or leaves, which cancome into contact with the hot exhaust sys-tem and cause such materials to ignite undercertain wind and weather conditions.
• Excessive starter cranking (in excess of oneminute), or an intermittently firing or floodedengine can cause three-way catalytic con-verter or exhaust system overheating.
• Remember that tampering or unauthorizedmodifications to the engine, the Engine Con-trol Module, or the vehicle may be illegal andcan cause three-way catalytic converter orexhaust system overheating. This includes:altering fuel injection settings or compo-nents, altering emission system components or location or removing components, and/orrepeated use of leaded fuel.NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensorsThe heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fedinto a control module that continuously monitorsengine functions and controls fuel injection. Theratio of fuel to air into the engine is continuouslyadjusted for efficient combustion to help reduceharmful emissions.

Jump starting
Follow the instructions provided here to jump start your vehicle or to jump start another vehi-cle.
Jumper cable connecting points
If the 12-volt auxiliary battery to be used is in
another vehicle, check that the vehicles are not touching to prevent premature completion of acircuit. Be sure to follow jump starting instruc-tions provided for the other vehicle.
1. Switch off the ignition in your vehicle (set the
ignition to mode 0).
