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.

Seat belts
Seat belts should always be worn by all occu- pants of your vehicle. Children should be prop-erly restrained, using an infant, car, or boosterseat determined by age, weight and height.
Most states and provinces make it mandatory for occupants of a vehicle to use seat belts.
Reversible seat belt pretensionersReversible seat belt pretensioners is a system inthe front seats that pulls the seat belts slightlytaut prior to a collision. This function helps posi-tion the front seat occupants to help improve theeffects of other safety systems, e.g., the airbagsystem.
Seat belt maintenanceCheck periodically that the seat belts are in goodcondition. Use water and a mild detergent forcleaning. Check seat belt mechanism function asfollows: attach the seat belt and pull rapidly onthe strap.
WARNING
• Never repair the belt yourself; have this work done by a trained and qualifiedVolvo service technician only.
• Any device used to induce slack into theshoulder belt portion of the three-pointbelt system will have a detrimental effecton the amount of protection available toyou in the event of a collision.
• The seat back should not be tilted too farback. The shoulder belt must be taut inorder to function properly.
• Do not use child safety seats or childbooster cushions/backrests in the frontpassenger's seat. We also recommendthat children who have outgrown thesedevices sit in the rear seat with the seatbelt properly fastened.

Engine compartment overview
The engine compartment overview shows some maintenance points.
The layout of the engine compartment may differ slightly from model to model
Coolant expansion tank
Brake fluid reservoir
Washer fluid reservoir
Relay/fuse box
Air cleaner
Engine oil filler cap
WARNING
• The cooling fan (located at the front of the engine compartment, behind the radi-ator) may start or continue to operate (forup to 6 minutes) after the engine hasbeen switched off.
• Engine cleaning should only be done by aworkshop. If engine cleaning agents areused when the engine has been running,there may a fire risk.
• Before performing any operations in theengine compartment, the ignition shouldalways be completely switched off (in mode
0) and there should be no remote
keys in the passenger compartment. Thegear selector should be in the P (park)
position. If the engine has been running, wait until it has cooled before touchingany components in the engine compart-ment.
• The distributor ignition system operatesat very high voltages. Special safety pre-cautions must be followed to preventinjury. Always turn the ignition off whenreplacing distributor ignition componentse.g. plugs, coil, etc.
• Do not touch any part of the distributorignition system while the engine is run-ning. This may result in unintended move-ments and body injury.

WARNING
•Exceeding the permissible axle weight, gross vehicle weight, or any other weightrating limits can cause tire overheatingresulting in permanent deformation orcatastrophic failure.
• Do not use replacement tires with lowerload carrying capacities than the tires thatwere original equipment on the vehiclebecause this will lower the vehicle's GVWrating. Use only tires with the correct loadcarrying capacity. Consult your Volvoretailer for information.

Uniform Tire Quality Grading
ALL PASSENGER VEHICLE TIRES MUST CONFORM TO FEDERAL SAFETY REQUIRE-MENTS IN ADDITION TO THESE GRADES .
Quality grades can be found, where applica- ble, on the tire sidewall between the treadshoulder and maximum section width. Forexample: Treadwear 200 Traction AA Temperature A
TREADWEARThe treadwear grade is a comparative rating based on the wear rate of the tire when testedunder controlled conditions on a specified gov-ernment test course. For example, a tire graded150 would wear one and one half (1 ½) times aswell on the government course as a tire graded100. The relative performance of tires dependsupon the actual conditions of their use, however,and many depart significantly from the norm dueto variation in driving habits, maintenance practi-ces and differences in road characteristics andclimate.
TRACTIONThe traction grades, from highest to lowest, areAA, A, B, and C, as measured under controlledconditions on specified government test surfacesof asphalt and concrete. A tire marked C mayhave poor traction performance. The tractiongrade assigned to this tire is based on braking (straight-ahead) traction tests and is not a meas-ure of cornering (turning) traction.
WARNING
The traction grade assigned to this tire is based on braking (straight-ahead) tractiontests and is not a measure of cornering (turn-ing) traction.
TEMPERATUREThe temperature grades are A (the highest), B, and C, representing the tire's resistance to thegeneration of heat and its ability to dissipate heatwhen tested under controlled conditions on aspecified indoor laboratory test wheel. Sustainedhigh temperature can cause the material of thetire to degenerate and reduce tire life, and exces-sive temperature can lead to sudden tire failure.The grade C corresponds to a minimum level ofperformance that all passenger vehicle tires mustmeet under the Federal Motor Safety StandardNo. 109. Grades B and A represent higher levelsof performance on the laboratory test wheel thanthe minimum required by law.
WARNING
The temperature grade for this tire is estab- lished for a tire that is properly inflated andnot overloaded. Excessive speed, under-infla-tion, or excessive loading, either separately orin combination, can cause heat buildup andtire failure.

PRACTICAL INFORMATION
104When the system detects a malfunction, the tell- tale will flash for approximately one minute andthen remain continuously illuminated. Thissequence will continue upon subsequent vehiclestart-ups as long as the malfunction exists. Whenthe malfunction indicator is illuminated, the sys-tem may not be able to detect or signal low tirepressure as intended. TPMS malfunctions may occur for a variety of reasons, including the installation of replacementor alternate tires or wheels on the vehicle thatprevent the TPMS from functioning properly.Always check the TPMS malfunction telltale afterreplacing one or more tires or wheels on yourvehicle to ensure that the replacement or alter-nate tires and wheels allow the TPMS to con-tinue to function properly.
Messages in the instrument panel
When the TPMS symbol illuminates, the following text messages may also be displayed:
•
Tire pressure low Check tires, calibrate
after fill
•Tire pressure system Temporarily
unavailable
•Tire pressure system Service required
If TPMS cannot determine which tire(s) have low inflation pressure:
• All four tires will be shown as affected in thecenter display After changing wheels, always calibrate the sys-tem to avoid false warnings. TPMS does not replace the need for regular tire inspection and maintenance.
NOTE
If you change to tires with a different dimen- sion than the factory-installed ones, theTPMS system must be calibrated for thesetires. TPMS cannot be turned off.
WARNING
Incorrect inflation pressure could lead to tire failure, resulting in a loss of control of thevehicle.
