Introduction
WARNING!
CALIFORNIA proposition 65
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.
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 freons, lead chromates, naphtanates, asbestos, mercury and cadmium; and reduced the
amount 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% 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, 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
controlled 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. 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 decreased fuel economy with improperly inflated tires.
Follow the recommended maintenance schedule in your Warranty and Service Records Information booklet.

Occupant safety
Volvo's concern for safety
Safety is Volvo's cornerstone. Our concern dates back to 1927 when the first Volvo rolled off the production line.
Three-point seat belts (a Volvo invention), safety cages, and energy-absorbing impact zones were designed into Volvo
cars long before it was fashionable or required by government regulation.
We will not compromise our commitment to safety. We continue to seek out new safety features and to refine those
already in our cars. You can help. We would appreciate hearing your suggestions about improving automobile safety.
We also want to know if you ever have a safety concern with your car. Call us in the U.S. at: 1-800-458-1552 or in
Canada at: 1-800-663-8255.
Occupant safety reminders
How safely you drive doesn't depend on how old you are but rather on:
How well you see.
Your ability to concentrate.
How quickly you make decisions under stress to avoid an accident. The following suggestions are intended to help
you cope with the ever changing traffic environment.
Never drink and drive.
If you are taking any medication, consult your physician about its potential effects on your driving abilities.
Take a driver-retraining course.
ProCarManuals.com

The seat belt reminder reacts if the driver and/or the front seat passenger have not fastened their seat belts.
The indicator light above the mirror and the symbol in the instrument panel will light up and stay lit until the seat
belt(s) have been fastened, or until the remaining 5 minutes of the 6-minute cycle have elapsed.
The chime will sound for 6 seconds, at 30-second intervals. The frequency of the chiming increases with the speed
of the car.
After 6 minutes, the chime will no longer sound and the indicator lights will go out.
Seat belt maintenance
Check periodically that the seat belts are in good condition. Use water and a mild detergent for cleaning. Check seat
belt mechanism function as follows: attach the seat belt and pull rapidly on the strap.
pg. 14 Supplemental Restraint System (SRS)
Supplemental Restraint System
As an enhancement to the three-point seat belts, your Volvo is equipped with a Supplemental Restraint System (SRS).
Volvo's SRS consists of seat belt tensioners, front airbags, side impact airbags, the occupant weight sensor, and
inflatable curtains. All of these systems are monitored by the SRS control module. An SRS warning light in the
instrument panel (see the illustration above) illuminates when the ignition key is turned to position I, II, or III, and will
normally go out after approximately 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 functioning properly, the general warning 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 interference in the system could cause
malfunction 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 disconnecting 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 technician for repairs.

Wait at least one minute.
Insert the key in the ignition and turn it to position II.
Press firmly on the brake pedal.
Move the gear selector from (P)ark to the (N)eutral position. See page 105 for information on manually overriding
the shiftlock system.
pg. 15 Front airbags
Front airbags
The front airbag system
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 generators (1) surrounded by the airbags (2) and a deceleration sensor (3) that
activates the gas generators, causing the airbags to be inflated with nitrogen gas.
Location of the passenger's side front airbag
As the movement of the seats' occupants compresses the airbags, some of the gas is expelled at a controlled rate to
provide better cushioning. Both seat belt tensioners also deploy, minimizing seat belt slack. The entire process,
including inflation and deflation of the airbags, takes approximately one fifth of a second.
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.
ProCarManuals.com

WARNING!
The airbags in the vehicle are designed to be a SUPPLEMENT to-not a replacement 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
housing.
The front airbags are designed to help prevent serious injury. Deployment occurs very quickly and with
considerable 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 equipment, make sure that the front airbag system is not damaged. Any interference
in the system could cause malfunction.
pg. 16 Front airbags
Front airbag deployment
The front airbags are designed to deploy during certain frontal or front -angular collisions, impacts, or decelerations,
depending 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 tensioners
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 collision where deployment occurs, the
airbags and seat belt tensioners activate. 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 dual-threshold, dual-stage front airbags use special sensors that are integrated with the front seat buckles.
The point at which the airbag 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 dual-stage airbags are triggered at 70% of their total capacity. If the impact is more severe, the
dual-stage airbags are triggered at full capacity.
Should you have questions about any component in the SRS system, please contact a trained and qualified Volvo
service technician or Volvo Customer Support:

Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than 4 feet 7 inches (140 cm) be seated in the
back seat of any vehicle with a front passenger side airbag, and be properly restrained for their size and weight. See
also the child safety recommendations on page 31
.
ProCarManuals.com

The passenger's side front airbag is automatically enabled/disabled by the Occupant Weight Sensor (OWS), a system
that monitors the weight of the person or object in the front passenger's seat. The system consists of a silicone-filled
bag located under the padding in the front passenger's seat Occupant Weight Sensor - disabling the passenger's side
front airbag cushion, a control module located under this seat, and a seat belt tension sensor, located on the outboard
side of the seat.
The OWS system continuously monitors the pressure on the front passenger's seat cushion and the tension applied to
the seat belt. Based on this data, OWS assesses the weight of the occupant or object in the front passenger's seat. This
information is transmitted to the SRS system control module, which enables or disables the passenger's side front
airbag accordingly, as indicated in the table below.
If the system is functioning normally, the status of the front passenger's side airbag (enabled/disabled) will be shown
by the OWS indicator light as explained in the table to the right. The OWS indicator light is separate and in addition to
the SRS warning light in the instrument panel.
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 and then go out. However, if a fault is detected in the system:
The OWS indicator light will stay on
The SRS warning light (see page 14) will come on and stay on
The message PASS. AIRBAG OFF SERVICE URGENT will be displayed in the information display.
pg. 19 Occupant Weight Sensor - disabling the passenger's side front airbag
WARNING!
If a fault in the system is detected and indicated as explained on the preceding page, be aware that the passenger's
side front airbag 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 technician as soon as possible.
