Welcome to the worldwide family of Volvo owners.
We trust that you will enjoy many years of safe driv-
ing in your Volvo, an automobile designed with your
safety and comfort in mind. To help ensure your
satisfaction with this vehicle, we encourage you to
familiarize yourself with the equipment descriptions,
operating instructions and maintenance requirements/
recommendations in this manual. We also urge you
and your passengers to wear seat belts at all times in
this or any other automobile. And, of course, please
do not operate a vehicle if you may be affected by
alcohol, medication or any impairment that could
hinder your ability to drive.Your Volvo is designed to meet all applicable safety and
emission standards, as evidenced by the certification
labels attached to the driver's door opening and on the

General information
Important
Before you operate your car for the first time, please familiarize
yourself with the new-engine oil consumption information on page
160. You should also be familiar with the information in chapters
one, two and four of this manual.
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 car for ready access.
Do not export your Volvo to another country before investigating
that country’s applicable safety and exhaust emission 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 and that
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.
CALIFORNIA Proposition 65 Warning
WARNING! Engine exhaust, some of its constituents, and certain
vehicle components contain or emit chemicals known to the state of
California to cause cancer, and birth defects or other reproductive
harm. In addition, certain fluids contained in vehicles and certain
products of component wear contain or emit chemicals known to the
State of California to cause cancer, and birth defects or other
reproductive harm.
Shiftlock
When your car is parked, the gear selector is locked in the (P)ark
position. To release the selector from this position, turn the ignition key
to position II (or start the engine), depress the brake pedal, press the
button on the front of the gear selector knob and move the selector from
(P)ark.
Keylock
This means that when you switch off the ignition, the gear selector must
be in the (P)ark position before the key can be removed from the
ignition switch.
Anti-lock Brake System (ABS)
The ABS system in your car performs a self-diagnostic test when the
vehicle first reaches the speed of approximately 12 mph (20 km/h). The
brake pedal will pulsate several times and a sound may be audible from
the ABS control module. This is normal.
Fuel filler door
Press the button on the light switch panel (see page 35) when the car is at
a standstill to unlock the fuel filler door. Please note that the fuel filler
door will remain unlocked until the car begins to move forward.
An audible click will be heard when the fuel filler door relocks.
Fuel filler cap
After refueling, close the fuel filler cap by turning it clockwise until it
clicks into place. If this cap is not closed tightly or if the engine is
running when the car is refueled, the Malfunction Indicator Lamp
(“Check Engine” light) may indicate a fault.
WARNING! If your vehicle is involved in an accident, unseen damage
may affect your vehicle's driveability and safety.

Volvo and the environment
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 de-
creased fuel economy with improperly inflated tires
•Follow the recommended maintenance schedule in your Warranty and
Service Records Information 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
PremAir®
On the surface of the radiator in the engine compartment, there is a special
coating called PremAir®. PremAir® works as a catalytic converter,
converting most of the ozone passing through the radiator into oxygen,
thereby reducing harmful ground-level ozone.
PremAir is a registered trademark of Engelhard Corporation.
Volvo is committed to the well being of our 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 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 manufac-
turer 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 con-
trolled 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.

Trip computer controls and functions
The four* trip computer functions can be accessed by twisting control B
one step at a time in either direction. Twisting the control a fifth time**
returns you to the original function.The trip computer can be reset (current data will be erased from system
memory) by pressing RESET (button C).
1. Driving distance on current fuel reserve
This function shows the approximate distance that can be driven on the
fuel remaining in the tank. This calculation is based on average fuel
consumption during the last 12 miles (20 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), “----” will be displayed in the text window.
2. Average fuel consumption
This value indicates fuel consumption since the last time the trip
computer was reset (by pressing RESET, button C). When the engine is
switched off, information on fuel consumption is stored and remains in
system memory until the RESET (button C) is pressed again.
3. Current fuel consumption
This value indicates the current fuel consumption, based on readings
taken once per second. When the car is not moving, “----” will be
displayed.
4. Average speed
This value indicates average speed since the last time the trip computer
was reset (by pressing RESET, button C). When the engine is switched
off, information on average speed is stored and remains in system
memory until the RESET (button C) is pressed again.
5. Current speed in miles per hour (Canadian models only)
This function provides the driver with an instantaneous conversion of the
car’s current speed from km/h to mph.

Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the
windows and moonroof (option) for several minutes before driving will
help release the warm air from the passenger compartment. When the
engine is running, close the windows and moonroof and use the
recirculation function for several minutes to enable the air conditioning
to cool the compartment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the windows and optional moon-
roof are closed. If you drive with the moonroof open, we recommend
that you manually adjust the temperature and blower control (the LED in
the AUTO switch should be off).
