Volvo and the environment
Volvo is committed to the well being of its cus-
tomers. 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 environ-
mental 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 emis-
sions 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 elec-
tronic engine controls and cleaner fuels are
bringing us closer to our goal. In addition tocontinuous environmental refinement of con-
ventional gasoline-powered internal combus-
tion engines, Volvo is actively looking at
advanced technology alternative-fuel vehicles.
When you drive a Volvo, you become our part-
ner 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 econ-
omy with improperly inflated tires.
•Follow the recommended maintenance
schedule in your Warranty and Service
Records Information booklet.
•Drive at a constant speed whenever pos-
sible.
•See a trained and qualified Volvo service
technician as soon as possible for inspec-
tion if the check engine (malfunction indi-
cator) light illuminates, or stays on after the
vehicle has started.
•Properly dispose of any vehicle-related
waste such as used motor oil, used batter-
ies, brake pads, etc.
•When cleaning your vehicle, please use
genuine Volvo car care products. All Volvo
car care products are formulated to be
environmentally friendly.
RecyclingAs part of Volvo’s commitment to the environ-
ment, it is essential for the vehicle to be recy-
cled in an environmentally sound way. Almost
the entire vehicle can be recycled and for that
reason, the vehicle’s final owner is requested
to contact a Volvo retailer for information about
approved and certified recycling facilities.

Malfunction Indicator Light
As you drive, a computer called On-Board
Diagnostics II (OBDII) monitors your vehicle's
engine, transmission, electrical and emission
systems.
The malfunction indicator (CHECK ENGINE)
light will illuminate if the computer senses a
condition that potentially may need correcting.
When this happens, please have your vehiclechecked by a trained and qualified Volvo serv-
ice technician as soon as possible.
A malfunction indicator (CHECK ENGINE) light
may have many causes. Sometimes, you may
not notice a change in your car's behavior.
Even so, an uncorrected condition could hurt
fuel economy, emission controls, and drivabil-
ity. Extended driving without correcting the
cause could even damage other components
in your vehicle.
This light may illuminate if the fuel filler cap is
not closed tightly or if the engine was running
while the vehicle was refueled.
Canadian models are equipped with this
symbol.
Anti-lock Brake System (ABS)
warning light
If the warning light comes on, there may be a
malfunction in the ABS system (the standard
braking system will still function). Check the
system by:
1. Stopping in a safe place and switching off
the ignition.
2. Restart the engine.
3. If the warning light goes off, no further
action is required.If the warning light remains on, the vehicle
should be driven to a trained and qualified
Volvo service technician for inspection, see

mal and the light stays on after restart, have the
vehicle towed to the nearest trained and quali-
fied Volvo service technician. This is normal,
provided it goes off when the engine speed is
increased.
Parking brake applied
This symbol illuminates when the parking
brake is applied. On models equipped with the
electric parking brake, this symbol flashes
while the brake is being applied and then glows
steadily.
A flashing symbol means that a fault has been
detected. See the message in the information

using the parking brake.
Airbags – SRS
If this light comes on while the vehicle is being
driven, or remains on for longer than approxi-
mately 10 seconds after the vehicle has been
started, the SRS system's diagnostic functions
have detected a fault in a seat belt lock or pre-
tensioner, a front airbag, side impact airbag,
and/or an inflatable curtain. Have the system(s)
inspected by a trained and qualified Volvo
service technician as soon as possible.

This symbol comes on for approximately 6 sec-
onds if the driver has not fastened his or her
seat belt.
Generator not charging
This symbol comes on during driving if a fault
has occurred in the electrical system. Contact
an authorized Volvo workshop.
Engine temperatureEngine overheating can result from low oil or
coolant levels, towing or hard driving at high
heat and altitude, or mechanical malfunction.
Engine overheating will be signaled with text
and a red warning triangle in the middle of the
instrument display. The exact text will depend
on the degree of overheating. It may range from
High engine temp Reduce speed to High
engine temp Stop engine. If appropriate,
other messages, such as Coolant level low,
Stop safely will also be displayed. If your
engine does overheat so that you must stop the
engine, always allow the engine to cool before
attempting to check oil and coolant levels.
See page 258 for more information.
Fault in brake system
If this symbol lights, the brake fluid level may
be too low. Stop the vehicle in a safe place and
check the level in the brake fluid reservoir, see
page 258. If the level in the reservoir is belowMIN, the vehicle should be transported to an
authorized Volvo workshop to have the brake
system checked.
Canadian models are equipped with this
symbol.
If the
and symbols come on at the
same time, there may be a fault in the brake
force distribution system.
1. Stop the vehicle in a safe place and turn off
the engine.
2. Restart the engine.
•If both symbols extinguish, continue driv-
ing.
•If the symbols remain on, check the level in
the brake fluid reservoir, see page 258. If
the brake fluid level is normal but the sym-
bols are still lit, the vehicle can be driven,
with great care, to an authorized Volvo
workshop to have the brake system
checked.
•If the level in the reservoir is below MIN, the
vehicle should be transported to an author-
ized Volvo workshop to have the brake
system checked.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a warning message
is displayed in the text window: DO
NOT DRIVE. Have the vehicle towed to
a trained and qualified Volvo service
technician and have the brake system
inspected.
•If the ABS and Brake system lights are
on at the same time, there is a risk of
reduced vehicle stability.
Warning symbol
The red warning symbol lights up to indicate a
problem related to safety and/or drivability. A
message will also appear in the main instru-
ments panel's display. The symbol remains
visible until the fault has been rectified but the
text message can be cleared with the READ
button, see page 124. The warning symbol can
also come on in conjunction with other sym-
bols.
Action:
1. Stop in a safe place. Do not drive the vehi-
cle further.
2. Read the information on the information
display. Implement the action in accord-
ance with the message in the display. Clear

All Wheel Drive – AWD3
Your Volvo can be equipped with permanent
All Wheel Drive, which means that power is
distributed automatically between the front
and rear wheels. Under normal driving condi-
tions, most of the engine's power is directed to
the front wheels. However, if there is any ten-
dency for the front wheels to spin, an electron-
ically controlled coupling distributes power to
the wheels that have the best traction.
NOTE
The message AWD disabled Service
required will be appear in the information
display if an electrical fault should occur in
the AWD system. A warning light will also
illuminate in the instrument panel. If this
occurs, have the system checked by a
trained and qualified Volvo service techni-
cian.

03 Your driving environment
Brakes
03

115 Brake system
The brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle with the other
brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.
A warning light in the instrument panel will light
up to warn the driver that a fault has occurred.
If this light comes on while driving or braking,
stop immediately and check the brake fluid
level in the reservoir.
NOTE
Press the brake pedal hard and maintain
pressure on the pedal – do not pump the
brakes.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a brake system message is
shown in the information display: DO NOT
DRIVE. Have the vehicle towed to a trained
and qualified Volvo service technician and
have the brake system inspected.
Brake lightsThe brake lights come on automatically when
the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event
of sudden braking or if the ABS system is acti-
vated. This function causes an additional tail-
light on each side of the vehicle to illuminate to
help alert vehicles traveling behind.
The adaptive brake lights activate if:
•The ABS system activates for more than
approximately a half second
•In the event of sudden braking while the
vehicle is moving at speeds above approx-
imately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake
lights and additional taillights remain on for as
long as the brake pedal is depressed or until
braking force on the vehicle is reduced.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing through an
automatic car wash can cause water to collect
on the brake discs and pads. This will cause a
delay in braking effect when the pedal is
depressed. To avoid such a delay when the
brakes are needed, depress the pedal occa-
sionally when driving through rain, slush, etc.
This will remove the water from the brakes.
Check that brake application feels normal. This
should also be done after washing or starting
in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usually
slower, which means that the cooling of the
brakes is less efficient than when driving on
level roads. To reduce the strain on the brakes,
shift into a lower gear and let the engine help
with the braking. Do not forget that if you are
towing a trailer, the brakes will be subjected to
a greater than normal load.
