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

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.

NOTE ENGINE OIL:
Although some oil consumption occurs during normal engine operation, more oil is consumed when the engine is new
as the internal parts generate higher friction while wearingin to each other. From the time the engine is new until the
first service is performed, the oil consumption could be higher than normal. For this reason, it is especially
important to check the oil every time you refuel your car during this period. See page 112.
In general, the rate of oil consumption depends on such factors as: engine temperature, length of trip, driving
conditions, oil viscosity and quality, engine speed and acceleration/deceleration.
ProCarManuals.com

Checking your engine oil level each time the car is refueled is one of the most important items you can perform to
help keep your car in good running order.
Deposit control gasoline (detergent additives)
Volvo recommends the use of gasoline containing deposit control additives. These additives have shown to be efficient
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 unleaded 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
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 methly-cyclopentadienyl
manganese tricarbonyl (MMT). If such fuels are used, your Emission Control System performance may be affected,
and the Malfunction Indicator Lamp located on your instrument panel may light. If this occurs, please return your
vehicle to an authorized Volvo retailer for service.
pg. 57 Fuel requirements, Refueling
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 an average of the Research Octane Number, RON, and the Motor Octane
Number, MON. (RON + MON/2).
The minimum octane requirement is AKI 87 (RON 91).
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 this page must still be
met.
Alcohol — Ethanol

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.
pg. 59 Starting the engine
Starting and stopping
ProCarManuals.com

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.
* If the key is left in the Drive position (position II) for more than 30 seconds, it must be turned to position 0 and then
turned to the Start position (position III) again in order to start the car. See page 21
for ignition key positions.
4. To release the gear selector from the (P)ark position (automatic transmission), the ignition key must be in position II
and the brake pedal must be depressed. See page 95
for instructions on manually releasing the SHIFTLOCK
system.
Do not race a cold engine immediately after starting. Oil flow may not reach some lubrication points fast enough to
prevent engine damage.
NOTE: (Automatic transmission only)
Your car is equipped with a KEYLOCK system. When the engine is switched off, the gear selector must be in the
( P )ark position before the starting key can be removed from the ignition switch.
5. Select the desired gear. The gear engages after a slight delay (automatic transmission) which is especially noticeable
when selecting R.
CAUTION : (Automatic transmission only)
The engine should be idling; never accelerate until after you feel the gear engage! Toorapid acceleration immediately
after selecting a gear will cause harsh engagement and premature transmission wear.
NOTE : Selecting P or N (automatic transmission) when idling at a standstill for prolonged periods of time will help
prevent overheating of transmission oil.
WARNING!
Always place the gear selector (automatic transmission) in Park and apply the parking brake before leaving the
vehicle. Never leave the car unattended with the engine running.
Always open the garage doors fully before starting the engine inside a garage to ensure adequate ventilation. The
exhaust gases contain carbon monoxide, which is invisible and odorless but very poisonous.

CAUTION:
Never race the engine immediately after starting. Oil flow may not reach some lubricating points fast enough to
prevent engine damage.
Do not race the engine just prior to switching off!
pg. 60 Manual transmission
Shift positions
Depress the clutch pedal completely when changing gears*.
Remove your foot from the clutch pedal while driving.
Overdrive (5th gear) should be used as often as possible to help improve fuel economy. This gear can be engaged at
speeds above approx. 50 mph (80 km/h).
CAUTION: Follow the shift pattern indicated on the gear shift knob when shifting up (e.g., do not shift directly from
2nd to 5th gear) to help avoid excessive wear on the transmission.
Engaging reverse gear
The gear lever must first be moved to neutral in order to engage reverse gear.

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.
