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.

Fuels containing up to 10% ethanol by volume may be used.
Ethanol may also be referred to as Ethyl alcohol, or "Gasohol".
Ethers — MTBE
Fuels containing up to 15% MTBE may be used.
Refueling
The fuel tank holds approximately 17.9 US gal. (68 liters) with sufficient volume left over to accommodate possible
expansion of the fuel in hot weather. Be aware that the "usable" tank capacity will be somewhat less than the specified
maximum. When the fuel level is low, such factors as ambient temperature, the fuel's "Reid vapor pressure"
characteristics, and terrain can affect the fuel pumps' ability to supply the engine with an adequate supply of fuel.
Therefore, it is advisable to refuel as soon as possible when the needle nears the red zone, or when the fuel warning
light comes on.
Fuel tank cover
The fuel tank cover (on the right rear fender) is locked and must be popped open using the control on the driver's door.
Open fuel filler cap slowly during hot weather conditions.
CAUTION:
· Do not refuel with the engine running. Turn the ignition off or to position I. If the ignition is on, an incorrect reading
could occur in the fuel gauge.
· After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
· Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
· Avoid spilling gasoline during refueling. Gasolines containing alcohol can cause damage to painted surfaces, which
may not be covered under the New Vehicle Limited Warranty.
· Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
* 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.
pg. 58 Driving economy
Economical driving conserves natural resources
ProCarManuals.com

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. 76 Wheels and tires
Checking and correcting tire pressure
· Check the tire pressure when refuelling.
· The tire pressure should be corrected only when the tires are cold.
· With warm tires, correct only when the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as recommended on the tire
information label* located on the rear facing edge of the passenger's door. This label lists both tire and vehicle design
limits.
Do not load your car beyond the load limits indicated.
*Please note that the tire information label indicates pressure for both comfort and fuel economy.
pg. 77 Wheels and tires
Uniform tire quality grading
ALL PASSENGER CAR TIRES MUST CONFORM TO FEDER-AL SAFETY REQUIREMENTS IN
ADDITION TO THESE GRADES
Quality grades can be found, where applicable, on the tire sidewall between the tread shoulder and maximum section
width. For example:
Treadwear 200 Traction AA Temperature A
TREADWEAR
The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as
well on the government course as a tire graded 100. The relative performance of tires depends upon the actual

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.

inspected at 60,000 miles (96,000 km) and thereafter, at 30,000 mile (48,000 km) intervals.
Cabin air filter
Replace the cabin air filter with a new one at 15,000 mile (24,000 km) intervals. Volvo recommends replacing the
filter more often if the car is driven under dirty and dusty conditions. The filter cannot be cleaned and therefore should
always be replaced with a new one.
pg. 110 Fuel/emissions systems
Fuel system
The fuel system is allelectronic and is microprocessorcontrolled. It can continually compensate for variation in engine
load, speed and temperature to give the best economy and power. A mass air flow sensor measures the inducted air. In
this way the system can make instantaneous adjustments for changes in air temperature or density, thus always
assuring the best economy with the lowest possible exhaust emissions.
Heated oxygen sensor
This is an emission control system designed to reduce emissions and improve 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 airfuel ratio to provide optimum conditions for combustion and efficient reduction of the three
major pollutants (hydrocarbons, carbon monoxide and oxides of nitrogen (NOx) by a threeway catalytic converter.
Crankcase ventilation
The engine is provided with positive crankcase ventilation which prevents crankcase gases from being released into the
atmosphere. Instead, the crankcase gases are admitted to the intake manifold and cylinders.
Evaporative control system
The car is equipped with an evaporative control system which prevents gasoline vapor from being released into the
atmosphere.
The system consists of a fuel tank with filler pipe and cap, a rollover valve, a Fill Limit Vent Valve (FLVV), vapor
vent lines, a charcoal canister, a purge line, a purge control valve and engine connections .
In addition, there is a pressure sensor connected to the fuel tank and a filter -protected Canister Close Valve (CCV) on
the atmospheric side of the canister, for system diagnosis.
The gasoline vapor is channeled through the rollover valve and the FLVV via the vapor vent lines into the charcoal
