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 Infromation 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

pg. 64 Driving economy
Economical driving conserves natural resources
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 short trips. Short trips do not allow the engine to reach normal operating
temperature.
· Drive carefully and avoid rapid acceleration and hard braking.
· Do not exceed posted speed limits.
· 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.
· Utilizing the fuel consumption modes in the Trip Computer 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 : The automatic transmission's ( D)rive position should be used as often as possible to help improve fuel
economy.
WARNING!
It is recommended that tires of the same make and dimensions be used on all four wheels (including the use of
snow tires). Do not use bias ply tires as this will adversely alter vehicle handling characteristics. Maintain correct tire
pressure.
Do not drive with trunk lid open! A warning light in the instrument panel will indicate that the trunk is open.
Poisonous exhaust gases may enter via the open trunk lid. If the trunk lid/tailgate must be kept open for any reason,
proceed as follows:
· Close the windows.
· Set the ventilation system control to air flow to floor, windshield and side windows and blower control to its
highest setting.

pg. 112 Fuel/emissions systems
Fuel system
The fuel system is all electronic and is microprocessor controlled. 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 air-fuel 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 three-way 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
