Introduction
Volvo and the environment

WARNING
CALIFORNIA proposition 65
Engine exhaust, some of its constituents,
and certain vehicle components contain or
emit chemicals known to the state of Cali-
fornia 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 Cali-
fornia to cause cancer, and birth defects or
other reproductive harm.
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 witha 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, recycling
is 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 onthe 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 System (SRS)
G027284
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 illuminates. If
this warning symbol is not func-
tioning properly, the general warn-
ing symbol illuminates and a text message 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
an authorized 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 P (Park) to
the N(Neutral) position.

01 Safety
Front airbags01

21 The front airbag system
G020111
The front airbags supplement the three-point
seat belts. For these airbags to provide the
protection intended, seat belts must be worn
at all times.
The front airbag system includes gas genera-
tors surrounded by the airbags, and decelera-
tion sensors that activate the gas generators,
causing the airbags to be inflated with nitrogen
gas.
G031006
Location of the passenger's side front airbag
As the movement of the seats' occupants com-
presses the airbags, some of the gas is expel-
led at a controlled rate to provide better cush-
ioning. Both seat belt pretensioners also
deploy, minimizing seat belt slack. The entire
process, including inflation and deflation of the
airbags, takes approximately one fifth of a sec-
ond.
The location of the front airbags is indicated by
SRS AIRBAG embossed on the steering wheel
pad and above the glove compartment, and by
decals on both sun visors and on the front and
far right side of the dash.
•The driver's side front airbag is folded and
located in the steering wheel hub.
•The passenger's side front airbag is folded
behind a panel located above the glove
compartment.

01 Safety
Front airbags 01

WARNING
•The airbags in the vehicle are designed
to be a SUPPLEMENT to–not a replace-
ment for–the three-point seat belts. For
maximum protection, wear seat belts at
all times. Be aware that no system can
prevent all possible injuries that may
occur in an accident.
•Never drive a vehicle with a steering
wheel-mounted airbag with your hands
on the steering wheel pad/airbag hous-
ing.
•The front airbags are designed to help
prevent serious injury. Deployment
occurs very quickly and with consider-
able force. During normal deployment
and depending on variables such as
seating position, one may experience
abrasions, bruises, swellings, or other
injuries as a result from deployment of
one or both of the airbags.
•When installing any accessory equip-
ment, make sure that the front airbag
system is not damaged. Any interfer-
ence in the system could cause mal-
function.
Front airbag deployment
•The front airbags are designed to deploy
during certain frontal or front-angular col-
lisions, impacts, or decelerations, depend-
ing on the crash severity, angle, speed and
object impacted. The airbags may also
deploy in certain non-frontal collisions
where rapid deceleration occurs.
•The SRS sensors, which trigger the front
airbags, are designed to react to both the
impact of the collision and the inertial
forces generated by it, and to determine if
the intensity of the collision is sufficient for
the seat belt pretensioners and/or airbags
to be deployed.
However, not all frontal collisions activate the
front airbags.
•If the collision involves a nonrigid object
(e.g., a snow drift or bush), or a rigid, fixed
object at a low speed, the front airbags will
not necessarily deploy.
•Front airbags do not normally deploy in a
side impact collision, in a collision from the
rear or in a rollover situation.
•The amount of damage to the bodywork
does not reliably indicate if the airbags
should have deployed or not.
NOTE
•Deployment of front airbags occurs only
one time during an accident. In a colli-
sion where deployment occurs, the air-
bags and seat belt pretensioners acti-
vate. Some noise occurs and a small
amount of powder is released. The
release of the powder may appear as
smoke-like matter. This is a normal
characteristic and does not indicate fire.
•Volvo's front airbags use special sen-
sors that are integrated with the front
seat buckles. The point at which the air-
bag deploys is determined by whether
or not the seat belt is being used, as well
as the severity of the collision.
•Collisions can occur where only one of
the airbags deploys. If the impact is less
severe, but severe enough to present a
clear injury risk, the airbags are trig-
gered at partial capacity. If the impact is
more severe, the airbags are triggered
at full capacity.
Should you have questions about any compo-
nent in the SRS system, please contact a
trained and qualified Volvo service technician

01 Safety
Occupant Weight Sensor01

25 Disabling the passenger's side front
airbag
G027050
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. For child safety recommen-
dations, see page 33.
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
The PASSENGER AIRBAG OFF indicator
lamp will illuminate for a short period of time
when the ignition is turned on to confirm it
is functional. When the front passenger's
seat is not occupied (empty seat) or in the
event that the passenger's side front airbag
is enabled (may inflate), the PASSENGER
AIRBAG OFF indicator lamp will be off.
However, if a fault is detected in the system:
•The OWS indicator light will stay on
•The SRS warning light (see page 20) 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
indicated as explained, be aware that
the passenger's side front airbag will
not deploy in the event of a collision.
•In this case, the safety systems and
Occupant Weight Sensor should be
inspected by a trained and qualified
Volvo service technician 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 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 willilluminate and stay on to remind you that the
passenger'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.In
rare situations when the seat belt is not properly fastened,
some child restraints may not be detected by the OWS
because there is very little weight on the vehicle seat cush-
ion. In these cases the passenger's side front airbag may be
disabled, but the PASSENGER AIRBAG OFF indicator lamp
will not be lit. Do not assume that the passenger's side front
airbag is disabled unless the PASSENGER AIRBAG OFFindicator lamp is lit. Make sure the child restraint is properly
installed (turn the vehicle off, remove the child restraint from
the vehicle and reinstall the restraint following the child
restraint manufacturer's instructions) and that the
PASSENGER AIRBAG OFF indicator lamp is on, or 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 is
sitting 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 seat back 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.
