sensor VOLVO S70 1998 Owners Manual

In production, Volvo has partly or completely phased out several chemicals including freons, lead chromates,
naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used in our plants 50% since 1991.
In use, Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda
sond, now called oxygen sensor, in 1976. The current version of this highly efficient system reduces emissions of
harmful substances (CO, HC, NOx) from the exhaust pipe by approximately 95% and the search to eliminate the
remaining emissions continues. Volvo is the only automobile manufacturer to offer CFC-free retrofit kits for the air
conditioning system for all models back to the M/Y 1975 240. Advanced electronic engine controls, refined
purification systems and cleaner fuels are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the next critical step in completing the life cycle. The
metal content is about 75% of the total weight of the car, which makes the car among the most recycled industrial
products. In order to have efficient and well controlled recycling, many Volvo variants have printed dismantling
manuals indication the weight and material of individual components. For Volvo, all homogeneous plastic parts
weighing more than 1.7 oz. (50 grams)are marked with international symbols that indicate how the component is to be
sorted for recycling.
In addition to continuous environmental refinement of conventional gasoline-powered internal combustion engines,
Volvo is actively looking at advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our partner in the work to lessen the car's impact on the environment. To reduce
your vehicle's environmental impact, you can:
Maintain proper air pressure in your tires. Tests have shown decreased fuel economy with improperly inflated
tires Follow the recommended maintenance schedule
Drive at a constant speed
See an authorized Volvo retailer as soon as possible for inspection if the check engine (malfunction indicator)
lamp illuminates, or stays on after the vehicle has started
Properly dispose of any vehicle related waste such as used motor oil, used batteries, brake pads, etc.
When cleaning your car, use Volvo's own car care products, all of which have systematically been adapted to
the environment.

Important
Before you operate your car for the first time, please familiarize yourself with the BREAK-IN information on page 66.
You should also be familiar with the information in the first three chapters of this manual.
Information contained in the balance of the manual is extremely useful and should be studied after operating the
vehicle for the first time.
This manual is structured so that it can be used for reference. It should thus be kept in the car for ready access.
Do not export your Volvo to another country before investigating the country's applicable safety and exhaust emission
requirements. In some cases it may be difficult or impossible to comply with these requirements. Modifications to the
emission control system(s) may render your Volvo not certifiable for legal operation in the U.S., Canada or other
countries.

Posted speed limits should not be exceeded.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
in keeping injectors and intake valves clean. Consistent use of deposit control gasolines will help ensure good
driveability and fuel economy. If you are not sure whether the gasoline contains deposit control additives, check with
the service station operator.
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 labeled "UNLEADED". Only these pumps have nozzles which fit
your car's filler inlet. It is unlawful to dispense leaded fuel into a vehicle labeled "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 Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
