Volvo and the environment
Volvo is committed to the well being of its customers. As a natural part of this commitment, we care about the
environment in which we all live. Caring for the environment means an everyday involvement in reducing our
environmental impact. Volvo's environmental activities are based on a holistic view, which means we consider the
overall environmental impact of a product
pg. 3 Introduction
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 chemicals including freons, lead
chromates, naphtanates, asbestos, mercury and cadmium; and reduced the amount of chemicals used 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% 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, 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 a 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, indicating 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 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) 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.

At highway driving speeds, fuel consumption will be lower with the air conditioning on and the windows closed
than with the air conditioning off and the windows open.
Using the onboard trip computer's fuel consumption modes can help you learn how to drive more economically.
Other factors that decrease gas mileage are:
Dirty air cleaner
Dirty engine oil and clogged oil filter
Dragging brakes
Incorrect front end alignment
Some of the above mentioned items and others are checked at the standard maintenance intervals.
Weight distribution affects handling
At the specified curb weight your vehicle has a tendency to understeer, which means that the steering wheel has to be
turned more than might seem appropriate for the curvature of a bend. This ensures good stability and reduces the risk
of rear wheel skid. Remember that these properties can alter with the vehicle load. The heavier the load in the cargo
area, the less the tendency to understeer.
WARNING!
Driving with the trunk open : Driving with the trunk open could lead to poisonous exhaust gases entering the
passenger compartment. If the trunk must be kept open for any reason,
Close the windows
Set the ventilation system control to air flow to floor, windshield and side windows and the blower control to its
highest setting.
CAUTION!
Drive slowly and carefully if going through standing water (i.e. flooded roadways, etc.). Damage to the engine could
result if excess water is drawn in through the air intake system. Never drive the vehicle in water deeper than 18
inches (48 cm).
Handling, roadholding
Vehicle load, tire design and inflation pressure all affect vehicle handling. Therefore, check that the tires are inflated to
pg. 99 Starting and driving
General information
the recommended pressure according to the vehicle load. See the "Tire pressure" section. Loads should be distributed
so that capacity weight or maximum permissible axle loads are not exceeded.
Cold weather precautions
If you wish to check your vehicle before the approach of cold weather, the following advice is worth noting:
Make sure that the engine coolant contains 50 percent antifreeze. Any other mixture will reduce freeze protection.
This gives protection against freezing down to -31°F (-35°C). See section "Coolant". The use of "recycled" antifreeze
is not approved by Volvo. Different types of antifreeze must not be mixed.
Volvo recommends using only genuine Volvo antifreeze in your vehicle's radiator.
Try to keep the fuel tank well filled - this prevents the formation of condensation in the tank. In addition, in
extremely cold weather conditions it is worthwhile to add fuel line de -icer before refueling.
The viscosity of the engine oil is important. Oil with low viscosity (thinner oil) improves cold-weather starting as

Washing and cleaning the car
Washing the car
The following points should be kept in mind when washing and cleaning the car:
The car should be washed at regular intervals since dirt, dust, insects and tar spots adhere to the paint and may cause
damage. To help prevent corrosion, it is particularly important to wash the car frequently in the wintertime.
Avoid washing your car in direct sunlight. Doing so may cause detergents and wax to dry out and become abrasive.
To avoid scratching, use lukewarm water to soften the dirt before you wash with a soft sponge, and plenty of sudsy
water.
Bird droppings: Remove from paintwork as soon as possible. Otherwise the finish may be permanently damaged.
A detergent can be used to facilitate the softening of dirt and oil.
A water-soluble grease solvent may be used in cases of sticky dirt. However, use a wash place equipped with a
drainage separator.
Dry the car with a clean chamois and remember to clean the drain holes in the doors and rocker panels.
Tar spots can be removed with kerosene or tar remover after the car has been washed.
A stiff-bristle brush and lukewarm soapy water can be used to clean the wiper blades. Frequent cleaning improves
visibility considerably.
Wash off the dirt from the underside (wheel housings, fenders, etc).
In areas of high industrial fallout, more frequent washing is recommended.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
Exterior plastic components
Cleaning exterior plastic components should be done with a cleaning agent specially designed for this purpose.
Solvents or stain removers should not be used. Consult your Volvo retailer.
NOTE: When washing the car, remember to remove dirt from the drain holes in the doors and sills.
CAUTION!
During high pressure washing, the spray mouthpiece must never be closer to the vehicle than 13" (30 cm). Do not
spray into the locks.
When washing or steam cleaning the engine, avoid spraying water or steam directly on the electrical components or
toward the rear side of the engine.

Operation in temperate climates
Incorrect viscosity oil can shorten engine life. Under normal use when temperatures do not exceed 86° F (30° C), SAE
5W -30 will provide good fuel economy and engine protection. See the viscosity chart.
Extreme engine operation
Synthetic oils meeting SAE 10W -30 and complying with oil quality requirements are recommended for driving in
areas of sustained temperature extremes (hot or cold), when towing a trailer over long distances, and for prolonged
driving in mountainous areas.
American Petroleum Institute (API) symbol
The API Service Symbol "donut" is divided into three parts:
The upper section describes the oil's performance level.
The center identifies the oil's viscosity.
The lower section indicates whether the oil has demonstrated energy-conserving properties in a standard test in
comparison to a reference oil.
pg. 192 Specifications
Engine specifications
Charge air cooler (Intercooler)
Turbocharged engines employ a turbo-compressor to force air into the engine inlet manifold and a charge air cooler to
cool the compressed inlet air. The resulting increase in air flow raises pressure in the intake manifold and increases
engine power over that developed by the normally-aspirated engine. The charge air cooler (which resembles a radiator)
is located between the turbo-compressor and inlet manifold.
Fuel system
The engine is equipped with a multiport fuel injection system.
