catalytic converter VOLVO S80 2008 Owners Manual

in our plants 50% since 1991.
Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda sond, now
called the heated 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 95-99% 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 of all models as far back as the 1975 model 240. Advanced electronic engine controls and cleaner
fuels are bringing us closer to our goal. After Volvo vehicles 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 a vehicle, which makes
the vehicle among the most recycled industrial products. In order to have efficient and well-controlled recycling,
dismantling information is available for all Volvo models. For Volvo, all homogeneous plastic parts weighing more
than 3.4 oz. (100 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 in your Warranty and Service Records Information booklet.
Drive at a constant speed whenever possible.
See a trained and qualified Volvo service technician as soon as possible for inspection if the check engine (
malfunction indicator) light 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 vehicle, please use genuine Volvo car care products. All Volvo car care products are
formulated to be environmentally friendly.

Fuel requirements
Deposit control gasoline (detergent additives)
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 light) located on your instrument panel may light. If this occurs, please
return your vehicle to a trained and qualified Volvo service technician 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 page 193
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.
Methanol
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
193 05 During your trip
Refueling

reading could occur in the fuel gauge.
Avoid overfilling the fuel tank. Do not press the handle on the filler nozzle more than one extra time. Too much
fuel in the tank in hot weather conditions can cause the fuel to overflow. Overfilling could also cause damage to the
emission control systems.
1If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator
lamp) may indicate a fault. However, your vehicle's performance will not be affected. Use only Volvo original or approved fuel filler caps.
Emission controls
Three-way catalytic converter
Keep your engine properly tuned. Certain engine malfunctions, particularly involving the electrical, fuel or
distributor ignition systems, may cause unusually high three-way catalytic converter temperatures. Do not continue to
operate your vehicle if you detect engine misfire, noticeable loss of power or other unusual operating conditions, such
as engine overheating or backfiring. A properly tuned engine will help avoid malfunctions that could damage the three-
way catalytic converter.
Do not park your vehicle over combustible materials, such as grass or leaves, which can come into contact with the
hot exhaust system and cause such materials to ignite under certain wind and weather conditions.
Excessive starter cranking (in excess of one minute), or an intermittently firing or flooded engine can cause three-
way catalytic converter or exhaust system overheating.
Remember that tampering or unauthorized modifications to the engine, the Engine Control Module, or the vehicle
may be illegal and can cause three-way catalytic converter or exhaust system overheating. This includes: altering fuel
injection settings
197 05 During your trip
Refueling
or components, altering emission system components or location or removing components, and/or repeated use of
leaded fuel.
NOTE
Unleaded fuel is required for vehicles with three-way catalytic converters.
Heated oxygen sensors
The heated oxygen sensors monitor the oxygen content of the exhaust gases. Readings are fed into a control module
that continuously monitors engine functions and controls fuel injection. The ratio of fuel to air into the engine is
continuously adjusted for efficient combustion to help reduce harmful emissions.
198 05 During your trip
Loading
Introduction
The load carrying capacity of your vehicle is determined by factors such as the number of passengers, the amount of
cargo, the weight of any accessories that may be installed, etc.
NOTE

1On vehicles with the optional keyless drive, the remote key must be in the passenger compartment.
CAUTION
Please check with state and local authorities before attempting this type of towing, as vehicles being towed are
subject to regulations regarding maximum towing speed, length and type of towing device, lighting, etc.
If the vehicle's battery is dead, do not attempt to start the vehicle by pushing or pulling it as this will damage the
three-way catalytic converter(s). The engine must be jump started using an auxiliary battery (see page 109
).
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
205 05 During your trip
Emergency towing
Towing vehicles with front wheel drive/All Wheel Drive
Volvo recommends the use of flat bed equipment.
If wheel lift equipment must be used, please use extreme caution to help avoid damage to the vehicle. In this case,
the vehicle should be towed with the rear wheels on the ground if at all possible .
If it is absolutely necessary to tow the vehicle with the front wheels on the ground, please refer to the towing
information on the page 204
.
CAUTION
Sling-type equipment applied at the front will damage radiator and air conditioning lines.
It is equally important not to use sling -type equipment at the rear or apply lifting equipment inside the rear
wheels; serious damage to the rear axle may result.
If the vehicle is being towed on a flat bed truck, the towing eyelets must not be used to secure the vehicle on the
flat bed. Consult the tow truck operator.
