Volvo and the environment
Volvo is committed to the well being of our 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 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.
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 as far back as 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 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
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

pedal for the first few minutes of operation. A cold engine uses more fuel and is subject to increased wear.
Whenever possible, avoid using the car for driving short distances. This does not allow the engine to reach normal
operating temperature.
Drive carefully and avoid rapid acceleration and hard braking.
Do not exceed speed limit.
Avoid carrying unnecessary items (extra load) in the car.
Maintain correct tire pressure. Check tire pressure regularly (check when tires are cold).
Remove snow tires when threat of snow or ice has ended.
Note that trunk-mounted luggage racks increase air resistance and thereby fuel consumption.
Avoid using automatic transmission kickdown feature unless necessary.
Avoid using the air conditioning when it is not required. When engaged, the air conditioner's compressor places an
additional load on the engine. However, please note that fuel consumption is lower with the air conditioning on than it
is when driving with the air conditioning switched off and the windows down.
If your car is equipped with the optional Trip Computer, utilizing the fuel consumption modes can help you "learn"
how to drive more economically.
Other factors which 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 Service intervals.
NOTE : (D)rive or 5th gear (manual transmissions) should be used as often as possible to help improve fuel economy.
pg. 64 Starting the Engine
Starting and stopping
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Move the seat closer if necessary. Refer to section "front seats".
2. Apply the parking brake, if not already set. The gear selector (automatic transmission) is locked in the (P)ark
position (SHIFT LOCK).
Manual transmission: the clutch must be fully depressed.
3. Without touching the accelerator pedal, turn the ignition key to the starting position*. Allow the starter to operate
for up to 10 seconds. Release the key as soon as the engine starts. If the engine fails to start, repeat step 3.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from the (P)ark position (automatic transmission), the ignition key must be in position II

NOTE: It is particularly important to wash the car frequently in the wintertime to prevent corrosion, when salt has
been used on the roads.
When washing the car, do not expose it to direct sunlight. Use lukewarm water to soften the dirt before you wash
with a sponge, and plenty of water, to avoid scratching.
Bird droppings: Remove from paintwork and the convertible top 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 *.
The power radio antenna must be dried after washing.
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.
CAUTION: During high pressure washing, the spray mouthpiece must never be closer to the painted surfaces of the
vehicle than 13" (30 cm). Do not spray directly 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.
After cleaning the engine, the spark plug wells should be inspected for water and blown dry if necessary.
Suitable detergents
Special car washing detergents should be used. A suitable mixture is about 2.5 fl. oz. (8.5 cl) of detergent to 2.6 US
gal. (10 liters) of warm water. After washing with a detergent the car should be well rinsed with clean water.
WARNING!
When the car is driven immediately after being washed, apply the brakes several times in order to remove any
moisture from the brake linings.
Engine cleaning agents should not be used when the engine is warm. This constitutes a fire risk.
Volvo offers an environmentally friendly Car Care Kit, containing waxing, washing, and degreasing agents.
NOTE: When washing the car, remember to remove dirt from the drain holes in the doors and sills. Bumpers: Wash
the bumpers with the same cleaning agent used on the rest of the car. Never clean the bumpers with gasoline or paint
thinner. Difficult spots can be removed with denatured alcohol. To avoid scratches, do not dry the bumpers with paper.

pg. 107 Cleaning the convertible top, Polishing and waxing
Cleaning the convertible top
CAUTION:
Some automatic car washes can damage the convertible top. For this reason, we recommend washing the car by
hand only.
Remember that the windows are lowered slightly when the convertible top is raised. Be sure the windows are closed
and the convertible top is completely raised and properly in place at the upper edge of the windshield before washing
the car. A chime indicates when the top has been fully raised (see page 40
).
Wash the convertible top with a mild detergent, wiping from the front towards the rear. Rinse thoroughly with clean
water.
Do not wash the convertible top with a high pressure spray.
After washing, the convertible top should be completely dry before it is folded down.
Remove bird droppings from the convertible top as soon as possible. Otherwise the top may be permanently stained.
A soft brush can be used to clean the convertible top between washings.
Winter: remove any residue of road salt from the convertible top as soon as possible.
Do not use solvents, tar remover or other all-purpose stain removers to clean the convertible top. Use Volvo
approved cleaning agents only - consult your Volvo retailer.
Polishing and waxing
Normally, polishing is not required during the first year after delivery, however, waxing may be beneficial.
Before applying polish or wax the car must be washed and dried. Tar spots can be removed with kerosene or tar
remover. Difficult spots may require a fine rubbing compound.
After polishing use liquid or paste wax.
Several commercially available products contain both polish and wax.
Waxing alone does not substitute for polishing a dull surface.
A wide range of polymer based car waxes can be purchased today. These waxes are easy to use and produce a long
lasting, highgloss finish that protects the bodywork against oxidation, road dirt and fading.

Cleaning the upholstery
The fabric can be cleaned with soapy water or a detergent. For more difficult spots caused by oil, ice cream, shoe
polish, grease, etc., use a clothing/fabric stain remover.
The plastic in the upholstery can be cleaned with a soft cloth and mild soap solution.
Leather upholstery can be cleaned with a soft cloth and mild soap solution. For more difficult spots, Volvo offers a

Engine
Liquid-cooled gasoline, 5-cylinder, in-line engine. Aluminum alloy cylinder block with cast-iron cylinder liners cast
directly into the block. Aluminum alloy cylinder head with double overhead camshafts and separate intake and outlet
channels.
Engine lubrication is provided by an eccentric pump driven from the crankshaft. Full-flow type oil filter. Exhaust
emission control is accomplished by multiport fuel injection, heated oxygen sensor(s) and three-way catalytic
converter.
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 by approx. 8.7
psi (over atmospheric pressure) and engine power output by approx. 50 horsepower 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.Designation: Volvo B 5234 T9
