or if the engine is running when the car is refueled, the Malfunction Indicator Lamp ("Check Engine" light) may
indicate a fault.
Points to keep in mind
Before you operate your vehicle for the first time, please familiarize yourself with the new-engine oil consumption
information on page 205
. You should also be familiar with the information found in the chapters "Instruments and
controls," and "Starting and driving."
Information contained in the balance of the manual is extremely useful and should be read after operating the
vehicle for the first time.
The manual is structured so that it can be used for reference. For this reason, it should be kept in the vehicle for
ready access.
Do not export your Volvo to another country before investigating that country's applicable safety and emission
control requirements. In some cases it may be difficult or impossible to comply with these requirements. Modifications
to the emission control system(s) may render your Volvo not certifiable for legal operation in the U.S., Canada and
other countries.
All information, illustrations and specifications contained in this manual are based on the latest product information
available at the time of publication. Please note that some vehicles may be equipped differently, depending on special
legal requirements. Optional equipment described in this manual may not be available in all markets.
Volvo reserves the right to make model changes at any time, or to change specifications or design without notice
and without incurring obligation.
WARNING
If your vehicle is involved in an accident, unseen damage may affect its driveability and safety.

7 Introduction
Volvo and the environment
Volvo is committed to the well being of its 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 CFCs, lead chromates, asbestos, and cadmium; and reduced the number of chemicals used
in our plants 50% since 1991.
Volvo was the first in the world to introduce into production a three-way catalytic converter with a Lambda sond, now
called the heated 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 95-99% 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 of all models as far back as the 1975 model 240. Advanced electronic engine controls and cleaner

based on average fuel consumption during the last 20 miles (30 km) of driving and the amount of fuel remaining in the
tank when the reading was taken. When the driving distance on current fuel reserve is less than 12 miles (20 km), "----
