2003 VOLVO XC70 catalytic converter

2003 VOLVO XC70
Volvo's environmental activities are based on a holistic view, which mea\
ns we consider the overall
environmental impact of a product throughout its complete life cycle. In\
this context, design, production,
product use, and recycling are all important considerations.
In production, Volvo has partly or completely phased out several chemica\
ls including freons, lead
chromates, naphtanates, asbestos, mercury and cadmium; and reduced the a\
mount 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 sy\
stem for all models as far back as
the M/Y 1975 240. Advanced electronic engine controls, refined purificat\
ion systems and cleaner fuels
are bringing us closer to our goal.
After Volvo cars and parts have fulfilled their use, recycling is the ne\
xt critical step in completing the
life cycle. The metal content is about 75% of the total weight of a car,\
which makes the car among the
most recycled industrial products. In order to have efficient and well c\
ontrolled recycling, many Volvo
variants have printed dismantling manuals, indicating the weight and mat\
erial 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 fo\
r recycling.
In addition to continuous environmental refinement of conventional gasol\
ine-powered internal
combustion engines, Volvo is actively looking at advanced technology alt\
ernative-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:
l Maintain proper air pressure in your tires. Tests have shown decreased f\
uel economy with improperly
inflated tires
l Follow the recommended maintenance schedule
l Drive at a constant speed
l See an authorized Volvo retailer as soon as possible for inspection if t\
he check engine (malfunction
indicator) lamp illuminates, or stays on after the vehicle has started \
l Properly dispose of any vehicle related waste such as used motor oil, us\
ed batteries, brake pads, etc.
l When cleaning your car, use Volvo's own car care products, all of which \
have systematically been
adapted to the environment

On the surface of the radiator in the engine compartment, there is a spe\
cial coating called PremAir®.
PremAir® works as a catalytic converter, converting most of the ozone\
passing through the radiator into
oxygen, thereby reducing harmful ground-level ozone.

pg. 84 Fuel requirements
Fuel requirements
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 a\
n average of the Research
Octane Number, RON, and the Motor Octane Number, MON. (RON + MON/2). T\
he minimum octane
requirement is AKI 87 (RON 91).
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additive\
s. These additives have shown
to be effective 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 unleade\
d 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 co\
verage. State and local vehicle
inspection programs will make detection of misfueling easier, possibly r\
esulting in emission test failure
for misfueled vehicles.
NOTE: Some U.S. and Canadian gasolines contain an octane enhancing additive ca\
lled methyl-
cyclopentadienyl manganese tricarbonyl (MMT). If such fuels are used, \
your Emission Control System
performance may be affected, and the Check Engine light (malfunction in\
dicator lamp) located on your
instrument panel may light. If this occurs, please return your vehicle t\
o an authorized Volvo retailer for
service.

Rear towing eyelet
Precautions when the car is in tow
l The steering wheel must be unlocked. Turn the ignition key to position I\
or II.
l The gear selector must be in position N.
l Maximum speed: 50 mph (80 km/h)
l Maximum distance with front wheels on ground: 50 miles (80 km).
l While the car is being towed, try to keep the tow rope taut at all times\
.
l Cars with an automatic transmission should only be towed in forward dire\
ction.
CAUTION:
l Please check with state and local authorities before attempting this typ\
e of towing, as vehicles being
towed are subject to regulations regarding maximum towing speed, length \
and type of towing device,
lighting, etc.
l If the car's battery is dead, do not attempt to start the vehicle by pus\
hing or pulling it as this will
damage the three-way catalytic converter(s). The engine must be jump s\
tarted using an auxiliary battery
(see
page 103).
l If the car is being towed on a flat bed truck, the towing eyelets must n\
ot be used to secure the car on
the flat bed. Consult the tow truck operator.
WARNING!
l Remember that the power brakes and power steering will not function when\
engine is not running.
The braking and steering systems will function but the brake pedal press\
ure required is 3 - 4 times
above normal and greater steering effort must be exerted.
l The towing eyelets must not be used for pulling another vehicle out of a\
ditch or for any similar
purpose involving severe strain.
l Do not use the towing eyelets to pull the car up onto a flat bed tow tru\
ck.

pg. 105 Long distance trips
Before a long distance trip
It is always worthwhile to have your car checked at a Volvo retailer bef\
ore driving long distances. Your
retailer will also be able to supply you with bulbs, fuses, spark plugs \
and wiper blades for your use in the
event that problems occur.
As a minimum, the following items should be checked before any long trip\
:
l Check that engine runs smoothly and that fuel consumption is normal.
l Check for fuel, oil, and fluid leakage.
l Check condition of accessory drive belts.
l Check transmission oil level*.
l Check state of the battery's charge.
l Examine tires carefully (the spare tire as well), and replace those th\
at are worn. Check tire pressures.
l The brakes, front wheel alignment, and steering gear should be checked b\
y your Volvo retailer only.
l Check all lights, including high beams.
l Reflective warning triangles are legal requirement in some countries.
l Have a word with your Volvo retailer if you intend to drive in countries\
where it may be difficult to
obtain the correct fuel.
l Consider your destination. If you will be driving through an area where \
snow or ice are likely to
occur, consider snow tires.
* To prevent injury from contact with hot surfaces, do not inspect your \
car's transmission fluid yourself.
Have your car's transmission fluid level inspected by a qualified Volvo \
service technician.

Three-way catalytic converter cautions
l Keep your engine properly tuned. Certain engine malfunctions, particular\
ly 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, no\
ticeable 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-wa\
y catalytic converters.
l Do not park your car 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 cer\
tain wind and weather
conditions.
l Excessive starter cranking (in excess of one minute), with an intermit\
tently firing or flooded engine,
can cause three-way catalytic converter or exhaust system overheating.
l Remember that tampering or unauthorized modifications to the engine or t\
he vehicle may be illegal
and can cause three-way catalytic converter or exhaust system overheatin\
g. This includes:
- Altering fuel injection setting or components.
- Altering emission system components or location or removing components\
.
- Repeated use of leaded fuel.
NOTE: Unleaded fuel is required for cars with three-way catalytic converters \

pg. 130 Fuel/emissions systems
Fuel system
The fuel system continually compensates for variation in engine load, sp\
eed and temperature. A mass air
flow sensor continuously measures the inducted air and makes rapid adjus\
tments for changes in air
temperature and density, to balance fuel economy, emissions, and engine \
power requirements.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and impr\
ove fuel economy. The heated
oxygen sensor monitors the composition of the exhaust gases leaving the \
engine. The exhaust gas
analysis is fed into an electronic module. This adjusts the air/fuel rat\
io to improve combustion and
reduce the three major pollutants (hydrocarbons, carbon monoxide, and o\
xides of nitrogen (NOx)) via a
three-way catalytic converter.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevent\
s crankcase gases from being
released into the atmosphere. Instead, the crankcase gases are routed to\
the intake manifold and
cylinders.
PremAir®
On the surface of the radiator in the engine compartment, there is a spe\
cial coating called PremAir®.
PremAir® works as a catalytic converter, converting most of the ozone\
passing through the radiator into
oxygen, thereby reducing harmful ground-level ozone.
Evaporative control system
The car is equipped with an evaporative control system, which prevents g\
asoline vapor from being
released into the atmosphere.
The system consists of a fuel tank with filler pipe and cap, two rollove\
r valves, a Fill Limit Vent Valve
(FLVV), vapor vent lines, a charcoal canister, a purge line, and a pur\
ge control valve and engine
connections. In addition, there is a pressure sensor connected to the fu\
el tank and a filter-protected
Canister Close Valve (CCV) on the atmospheric side of the canister, fo\
r system diagnosis.
The gasoline vapor is channeled through the rollover valves and the FLVV\
via the vapor vent lines into
the charcoal canister, where it is stored. When the engine is started, t\
he gasoline vapor is drawn from the
