Introduction
Volvo and the environment
12
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. After Volvo vehi-
cles and parts have fulfilled their use, recyclingis the next critical step in completing the life
cycle. The metal content is about 75% of the
total weight of a vehicle, which makes the vehi-
cle among the most recycled industrial prod-
ucts. In order to have efficient and well-con-
trolled recycling, dismantling information is
available for all Volvo models. For Volvo, all
homogeneous plastic parts weighing more
than 3.4 oz. (100 grams) are marked with inter-
national symbols that indicate how the com-
ponent is to be sorted for recycling. In addition
to continuous environmental refinement of
conventional gasoline-powered internal com-
bustion 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.

Supplemental Restraint System01

21 Supplemental Restraint System (SRS)
G026330
SRS warning light
As an enhancement to the three-point seat
belts, your Volvo is equipped with a Supple-
mental Restraint System (SRS). Volvo's SRS
consists of seat belt pretensioners, front air-
bags, side impact airbags, the occupant
weight sensor, and inflatable curtains. All of
these systems are monitored by the SRS con-
trol module. An SRS warning light in the instru-
ment panel (see the illustration) illuminates
when the ignition key is turned to position I, II,
or III, and will normally go out after approxi-
mately 7 seconds if no faults are detected in
the system.Where applicable, a text message will also be
displayed when the SRS warning light illumi-
nates. If this warning symbol is not functioning
properly, the general warning symbol illumi-
nates and either
SRS AIRBAG SERVICE
URGENT or SRS AIRBAG SERVICE
REQUIRED will be displayed.
WARNING
•If the SRS warning light stays on after
the engine has started or if it illuminates
while you are driving, have the vehicle
inspected by a trained and qualified
Volvo service technician as soon as
possible.
•Never try to repair any component or
part of the SRS yourself. Any interfer-
ence in the system could cause mal-
function and serious injury. All work on
these systems should be performed by
a trained and qualified Volvo service
technician.
WARNING
If your vehicle has been subjected to flood
conditions (e.g. soaked carpeting/standing
water on the floor of the vehicle) or if your
vehicle has become flood-damaged in any
way, do not attempt to start the vehicle or
put the key in the ignition before discon-
necting the battery (see below). This may
cause airbag deployment which could result
in personal injury. Have the vehicle towed to
a trained and qualified Volvo service tech-
nician for repairs.
Automatic transmission
Before attempting to tow the vehicle, use
the following procedure to override the
shiftlock system to move the gear selector
to the neutral position:
1. Switch off the ignition for at least
10 minutes and disconnect the battery.
2. Wait at least one minute.
3. Insert the key in the ignition and turn it
to position II.
4. Press firmly on the brake pedal.
5.
Move the gear selector from Park (P) to
the Neutral (N) position, see page 152,
for information on manually overriding
the shiftlock system.

G018082
Occupant Weight Sensor (OWS) indicator light
Volvo recommends that ALL occupants (adults
and children) shorter than 4 feet 7 inches
(140 cm) be seated in the rear seat of any vehi-
cle with a passenger's side front airbag, and be
properly restrained. Children should always be
seated in child restraints appropriate for their
size and weight. See also the child safety rec-
ommendations on page 35.
The Occupant Weight Sensor (OWS) is
designed to meet the regulatory requirements
of Federal Motor Vehicle Safety Standard
(FMVSS) 208 and is designed to disable (willnot inflate) the passenger's side front airbag
under certain conditions.
The OWS works with sensors that are part of
the front passenger's seat and seat belt. The
sensors are designed to detect the presence of
a properly seated occupant and determine if
the passenger's side front airbag should be
enabled (may inflate) or disabled (will not
inflate).
The OWS will disable (will not inflate) the pas-
senger's side front airbag when:
•the front passenger's seat is unoccupied,
or has small/medium objects in the front
seat,
•the system determines that an infant is
present in a rear-facing infant seat that is
installed according to the manufacturer's
instructions,
•the system determines that a small child is
present in a forward-facing child restraint
that is installed according to the manufac-
turer's instructions,
•the system determines that a small child is
present in a booster seat,
•a front passenger takes his/her weight off
of the seat for a period of time,
•a child or a small person occupies the front
passenger's seat.The OWS uses a PASSENGER AIRBAG OFF
indicator lamp which will illuminate and stay on
to remind you that the passenger's side front
airbag is disabled. The PASSENGER AIRBAG
OFF indicator lamp is located in the overhead
console, near the base of the rearview mirror.
NOTE
When the ignition is switched on, the OWS
indicator light will go on for up to 10 seconds
while the system performs a self-diagnostic
test.
However, if a fault is detected in the system:
•The OWS indicator light will stay on
•The SRS warning light (see page 21) will
come on and stay on
The message
PASS. AIRBAG OFF SERVICE
URGENT will be displayed in the information
display.

WARNING
If a fault in the system is detected and indi-
cated as explained on the preceding page,
be aware that the passenger's side front air-
bag will not deploy in the event of a collision.
In this case, the SRS system and Occupant
Weight Sensor should be inspected by a
trained and qualified Volvo service techni-
cian as soon as possible.
WARNING
•Never try to open, remove, or repair any
components in the OWS system. This
could result in system malfunction.
Maintenance or repairs should only be
carried out by an a trained and qualified
Volvo service technician.
•The front passenger's seat should not
be modified in any way. This could
reduce pressure on the seat cushion,
which might interfere with the OWS sys-
tem's function.
The OWS is designed to disable (will not inflate)
the passenger's side front airbag when a rear
facing infant seat, a forward-facing child
restraint, or a booster seat is detected. The
PASSENGER AIRBAG OFF indicator lamp will
illuminate and stay on to remind you that thepassenger's side front airbag is disabled (see
the following table).

AVolvo recommends that children always be properly
restrained in appropriate child restraints in the rear seats. Do
not assume that the passenger's side front airbag is disabled
unless the PASSENGER AIRBAG OFF indicator lamp is lit.
Make sure the child restraint is properly installed. If there is
any doubt as to the status of the passenger's side front air-
bag, move the child restraint to the rear seat.
The OWS is designed to enable (may inflate)
the passenger's side front airbag anytime the
system senses that a person of adult size issitting properly in the front passenger's seat.
The PASSENGER AIRBAG OFF indicator
lamp will be off and remain off.
If a person of adult size is sitting in the front
passenger's seat, but the PASSENGER
AIRBAG OFF indicator lamp is on, it is possible
that the person isn't sitting properly in the seat.
If this happens:
1. Turn the vehicle off and ask the person to
place the seatback in an upright position.
2. Have the person sit upright in the seat,
centered on the seat cushion, with the per-
son's legs comfortably extended.
3. Restart the vehicle and have the person
remain in this position for about two
minutes. This will allow the system to
detect that person and enable the pas-
senger's frontal airbag.
4.
If the PASSENGER AIRBAG OFF indicator
lamp remains on even after this, the person
should be advised to ride in the rear seat.
This condition reflects limitations of the OWS
classification capability. It does not indicate
OWS malfunction.

any way to accommodate a disability, for
example by altering or adapting the driver's or

Air conditioning – A/C
Your car is equipped with a climate control
system that includes either manually adjusta-
ble air conditioning or optional Electronic Cli-
mate Control (ECC).
The air conditioning system can be switched
off, but for optimal air quality in the passenger
compartment and to prevent the windows from
fogging, the air conditioning should be left on
– even in cool weather.
NOTE
In warm weather, a small amount of water
may accumulate under the car when it has
been parked. This water is condensation
from the A/C system and is normal.
Ice and snow
Always keep the air intake grille at the base of
the windshield free of snow.
Fog on the inside of the windows
The defroster function should be used to
remove fog or mist from the inside of the win-
dows. Keeping the windows clean with a com-
mercially available window washing spray will
also help prevent fogging or misting
Climate control maintenance
Special tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
Refrigerant
Volvo cares about the environment. The air
conditioning system in your car contains a
CFC-free refrigerant – R134a. This substance
will not deplete the ozone layer. The system
contains 1.2 lbs (530 g) R134a (HFC 134a), and
uses PAG oil.
Passenger compartment filter
Replace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
NOTE
There are different types of cabin air filters.
Ensure that the correct type is installed.
Display
The display above the climate control panel
shows the climate settings that have been
made.
Personal settings
There are two functions in the climate system
that can be set to your preferences:
•Blower speed to Auto mode (models with
ECC only).
•Timer controlled recirculation of the air in
the passenger compartment.

For information about how to make these set-
tings, see the Personal settings section on
page 82.
Models equipped with ECC*
Sensors
•The sunlight sensor is on the upper side of
the dashboard
•The passenger compartment temperature
sensor is located behind the climate sys-
tem control panel.
•The ambient temperature sensor is in the
driver's side door mirror.
•The humidity sensor is in the rearview mir-
ror.
These sensors should never be obstructed.
NOTE
The sunlight sensor monitors the side of the
vehicle from which the sun shines into the
passenger compartment. This means that
the temperature may differ slightly between
the left and right air vents, even if the climate
system temperature is set to be the same
for both sides of the passenger compart-
ment.
Side windows and optional moonroofThe electronic climate control system will func-
tion best if the windows and moonroof areclosed. If you drive with the windows or moon-
roof open, it may be preferable to manually
adjust the temperature and blower control (the
LED in the AUTO switch should be off).
AccelerationThe air conditioning system is temporarily
switched off during full throttle acceleration.

1. BlowerThe blower speed can be
increased or decreased by
turning the knob. If the knob is
turned counterclockwise and
the indicator light in the dis-
play goes out, the blower and
the air conditioning are
switched off. The display shows the blower
symbol and
OFF.
2. RecirculationThis function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e. no air
from outside the car is taken
into the car when this function is activated.
Recirculation (together with the air condition-
ing system) cools the passenger compartment
more quickly in very warm weather. If the air in
the car recirculates for too long, there is a risk
of condensation forming on the insides of the
windows, especially in winter.

TimerThe timer function minimizes the risk of mist-
ing, or stale air when the recirculation function
is selected, see page 82 for information on set-
ting the recirculation timer. Recirculation is
always disengaged when you select
Defroster (3).
3. DefrosterDirects airflow to the wind-
shield and side windows and
increases blower speed.
When the defroster is activated:
•Air flows to the windows at high blower
speed.
•The LED in the defroster button lights up
when this function is activated. The air con-
ditioning system is controlled to provide
maximum air dehumidification.
•The air conditioning is automatically
switched on (can be switched off by press-
ing button 5).
4. Airflow controlsPress one of the three buttons
in the illustration to activate
the selected airflow. A symbol
in the display above the cli-
mate control panel and a lit
LED in the selected button
indicate that the manual func-
tion has been selected. With manually selected
airflow both warm and cool air can be selected.
The desired temperature is selected using con-
trol 9.
5. A/C – On or OffON: The air conditioning sys-
tem is engaged when the ON
light is lit.

dow and door mirrors.
The rear window and door
mirrors are defrosted simulta-
neously if the switch is
pressed once. The defrost
function is active if the LED in the switch is illu-
minated.
•The function can be switched off manually
by pressing the button,
•The defrost function switches off automat-
ically after 12–20 minutes, depending on
the outside temperature.
NOTE
