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
· 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

Reads thousands of engine rpm. Do not drive for long with the needle in the red section. The engine has an inbuilt
function preventing too high a rotation speed. When this function operates, you may discern some pulsation, which in
that case is quite normal.

pg. 18 Warning lights
The warning lights described on pages 18 and 19 should never stay on when driving
When the ignition key is turned on and before the engine starts, all of the warning lights should go on to test the
function of the bulbs. Should a light not go off after the engine has started, the system indicated should be inspected.
However, the parking brake reminder light will not go off until the parking brake has been fully released.
Generator warning light
If the light comes on while the engine is running, have the charging system checked.
Malfunction indicator lamp
If the lamp comes on (or stays on after the vehicle has started), the engine diagnostic system has detected a possible
fault in the emission control system. Although driveability may not be affected, see an authorized Volvo retailer as
soon as possible for inspection.
NOTE : If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the 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.
Oil pressure warning light
If the light comes on while driving, stop the car and then stop the engine immediately and check the engine oil
level . See page 112
. If the light stays on after restart, have the car towed to the nearest authorized Volvo retailer. After
hard driving, the light may come on occasionally when the engine is idling. This is normal, provided it goes off when
the engine speed is increased.
Fault in ETC (Electronic Throttle Control system)
If this lamp comes on, there is a fault in the engine control system and driveability will be affected. Switch the ignition
off and then on again. If the light remains on, the system should be inspected by an authorized Volvo retailer.
Cruise Control
This light will be on when cruise control is engaged. Cruise control will automatically disengage when the ignition is
switched off.

Better driving economy may be obtained by thinking ahead, avoiding rapid starts and stops and adjusting the speed of
your vehicle to immediate traffic conditions. Observe the following rules:
· Bring the engine to normal operating temperature as soon as possible by driving with a light foot on the accelerator
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 roof racks, ski racks, etc., 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:
· Worn or dirty spark plugs
· Incorrect spark plug gap
· 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.

Washing 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.
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 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 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.
· 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.

1) Replace at 105,000 miles (168,000 km)
2) Brake fluid should be changed at owner request every second year or 30,000 miles (48,000 km). The fluid
should be replaced once a year or every 15,000 miles (24,000 km) when driving under extremely hard
conditions (mountain driving, etc.).
3) Rotate tires at owner request.
The following items should be checked weekly by the driver (it takes only a few minutes):
Engine oil level, brake fluid level, radiator coolant level, operation of all lights, horns, windshield wipers, tire
pressure (all five tires), windshield washer fluid level
The following should also be carried out at regular intervals:
Washing (check all drain holes), polishing, cleaning
pg. 108 Servicing
Hoisting the car
If a garage jack is used to lift the car, the two jack attachments points should be used. They are specially reinforced to
bear the weight of the car. A garage jack can also be placed under the front of the engine support frame and under the
reinforced plate in the spare wheel well. Take care not to damage the splash guard under the engine. Ensure that the
jack is positioned so that the car cannot slide off it. Always use axle stands or similar structures.
