sensor VOLVO S80 2002 Owners Manual

Important
Before you operate your car for the first time, please familiarize yourself with the new-engine oil consumption
information on page 116
. You should also be familiar with the information in the 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 requirments 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.
Volvo and the environment
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 manufacturer 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 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.

As an enhancement to the three-point seat belt system, your Volvo is equipped with a Supplemental Restraint System
(SRS). The Volvo SRS consists of an airbag (2) on both the driver's and passenger's sides and seat belt tensioners in
both front door pillars (4). The system is designed to supplement the protection provided by the three-point seat belt
system. All three rear seat belts are also equipped with tensioners.
The SRS system is indicated by the "SRS" embossed on the steering wheel pad and above the glove compartment, and
by decals on both sun visors and on the far right side of the dash.
The airbags are folded and located in the steering wheel hub and above the glove compartment. They 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 airbag system includes gas generators (1) surrounded by the airbags (2) and front seat belt tensioners for both of
the front seats (4). To deploy the system, the sensor (3) activates the gas generators causing the airbags to be inflated
with nitrogen gas. 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 any seat belt slack.
The entire process, including inflation and deflation of the airbags, takes approximately two-tenths of a second.WARNING!
· As its name implies, SRS is designed to be a SUPPLEMENT to - not a replacement for - the three-point belt
system. 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.
· When installing any optional equipment, make sure that the SRS system is not damaged. Do not attempt to service
any component of the SRS yourself. Attempting to do so may result in serious personal injury. If a problem arises,
take your car to the nearest authorized Volvo retailer for inspection as soon as possible.

A self -diagnostic system incorporated in the sensor monitors the SRS, SIPS and IC-system. This system does not,
however, monitor the Side Impact Protection System (SIPS) airbags. If a fault is detected, the warning light will
illuminate. The light is included in the warning/indicator light cluster in the instrument panel. Normally, the SRS
warning lamp should light up when the ignition key is turned to positions I, II or III and should go out after 7 seconds
or when the engine is started. Check that this light is functioning properly every time the car is started.
The following items are monitored by the self -diagnostic system:
· Sensor unit
· SRS wiring
· InflatorsWARNING!
· Never drive an SRS equipped car with your hands on the steering wheel pad / airbag housing.
· No objects, accessory equipment or stickers may be placed on, attached to or installed near the SRS cover in the
center of the steering wheel, the SRS cover above the glove compartment or the area affected by airbag deployment.
· If the SRS warning light stays on after the engine has started or if it comes on while you are driving, drive the car
to the nearest authorized Volvo retailer for inspection as soon as possible.
There is no maintenance to perform on the SRS yourself. The month and year shown on the decal on the door pillar
indicate when you should contact your Volvo retailer for specific servicing or replacement of airbags and seatbelt
tensioners. This service must be performed by an authorized Volvo retailer.
Should you have any questions about the SRS system, please contact
your authorized Volvo retailer or Volvo Customer Support:

pg. 6 Front airbags - SRS
WARNING!
Do not use child safety seats or child booster cushions/backrests in the front passenger's seat. We also recommend
that children under 4 feet 7 inches (140 cm) in height who have outgrown these devices sit in the rear seat with the
seat belt fastened.
NOTE: Deployment of SRS components occurs only one time during an accident. In a collision where deployment
occurs, the air bags 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.
NOTE: Volvo's dual-threshold air bags use special sensors 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.
ProCarManuals.com

NOTE: Volvo's dual-stage airbags: If the impact is less severe, but severe enough to present a clear injury risk, the
dual-stage airbags are triggered at just 70% of its total capacity. If the impact is more severe, the dual-stage airbags are
triggered with full capacity.
WARNING!
· Children must never be allowed in the front passenger seat. 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.
· Occupants in the front passenger's seat must never sit on the edge of the seat, sit leaning toward the instrument
panel or otherwise sit out of position. The occupant's back must be as upright as comfort allows and be against the
seat back with the seat belt properly fastened.
· Feet must be on the floor, e.g. not on the dash, seat or out of the window.
· No objects or accessory equipment, e.g. dash covers, may be placed on, attached to or installed near the SRS hatch
(the area above the glove compartment) or the area affected by airbag deployment (see illustration on page 4
).
· There should be no loose articles, e.g. coffee cups, on the floor, seat or dash area.
· Never try to open the SRS cover on the steering wheel or the passenger side SRS seam. This should only be done
by an authorized Volvo service technician.
· Failure to follow these instructions can result in injury to the vehicle occupants in an accident.
pg. 7 Front airbags - SRS
NOTE : The information on this page does not pertain to the Side Impact Protection System airbags.
When are the airbags deployed?
The SRS system is designed to deploy during certain frontal or frontangular collisions, impacts, or decelerations,
depending on the crash severity, angle, speed and object impacted. The SRS sensor is 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 airbags to be deployed.
WARNING!
The SRS is 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 of airbag(s) deployment.
If the airbags have been deployed, we recommend the following:
· Have the car towed to an authorized Volvo retailer. Never drive with the airbags deployed.
· Have an authorized Volvo retailer replace the SRS system components.
· Use only new, Genuine Volvo Parts when replacing SRS components (airbags, seat belts, tensioners, etc.).
When are the airbags NOT deployed? Not all frontal collisions activate the SRS system. If the collision involves a
nonrigid object (e.g., a snow drift or bush), or a rigid, fixed object at a low speed, the SRS system 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.
Seat belts the heart of the Volvo safety system The heart of the Volvo safety system is the threepoint seat belt (a
Volvo invention)! In order for the SRS system to provide the protection intended, seat belts must be worn at all times
ProCarManuals.com

by everyone in the car. The SRS system is a supplement to the seat belts.
WARNING!
If your car has been subjected to flood conditions (e.g. soaked carpeting/standing water on the floor of the vehicle)
or if your car has become flooddamaged 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 car towed to an authorized Volvo retailer for repairs.
Automatic transmission:
Before attempting to tow the car, use the following procedure to override the shiftlock system to move the gear
selector to the neutral position.
· Switch off the ignition for at least 10 minutes and disconnect the battery
· 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.
WARNING!
Never drive with the airbags deployed. The fact that they hang out can impair the steering of your car. Other safety
systems can also be damaged. The smoke and dust formed when the airbags are deployed can cause skin and eye
irritation in the event of prolonged exposure.
pg. 8 Side impact airbags (SIPS)
SIPS airbag (front seats only)
As an enhancement to the structural Side Impact Protection System built into your car, the car is also equipped with
Side Impact Protection System (SIPS) airbags. The SIPS airbag system consists of airbag modules built into the sides
of both front seat backrests (1), wires (2) and gas generators/sensor units (3).
The SIPS airbag system is designed to help increase occupant protection in the event of certain side impact collisions.
The SIPS airbags are designed to deploy only during certain sideimpact collisions, depending on the crash severity,
angle, speed and point of impact. The airbags are not designed to deploy in all side impact situations.

Sensors
The sunlight sensor on the dashboard and passenger compartment temperature sensor in the ECC control panel should
not be covered in any way as this could cause incorrect information to be sent to the ECC system.
Parking the car in warm weather
If your car has been parked in the sun in warm weather, opening the windows and sun roof (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 sun roof and use the recirculation function for several minutes to enable the air conditioning to
cool the compartment as quickly as possible.
Windows and optional sun roof
The ECC system will function best if the windows and optional sun roof are closed. If you drive with the sun roof
open, we recommend that you manually adjust the temperature and blower control (the LED in the AUTO switch
should be off).
Acceleration
The air conditioning is momentarily disengaged during full-throttle acceleration.
ECC maintenance
All maintenance on the climate control systems should be carried out by an authorized Volvo service technician only.
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 2.2 lbs (1000 g) R134a and uses PAG oil.
Passenger compartment blower
Approximately 50 minutes after the ignition is turned off, the blower may come on automatically, and run for five
minutes, to remove condensation in the A/C evaporator.BR>
pg. 45 Electronic Climate Control (ECC) - with Interior Air Quality system (option)
Interior Air Quality system (option)
Some cars are equipped with a multifilter and air quality sensor. The filter separates gases and particles, thereby
reducing the amounts of odors and contaminants entering the car. The air quality sensor detects increased levels of
contaminants in the outside air. When the air quality sensor detects contaminated outside air, the air intake closes and
the air inside the passenger compartment is recirculated, i.e. no outside air enters the car. The filter also cleans
recirculated passenger compartment air. When the Air quality sensor is activated, the LED AUT comes on in the
recirculation button
Operations:
Press
to activate the Air quality sensor (normal setting). Or select one of three functions by pressing
1. Press
the LED AUT comes on. The Air quality sensor is now activated.
2. Press
no LED is lighted. Recirculation not activated.
3. Press the LED MAN comes on. Recirculation is now activated. You can switch between these three functions
ProCarManuals.com

by repeatedly pressing
Keep the following in Mind:
· Make it a rule to have the air quality sensor activated at all times.
· Recirculation is limited in cold climates to avoid misting up.
· If misting occurs, you should deactivate the Air quality sensor.
· If the windows mist up, you can also use the windshield and side window defroster functions. See page 42
.
· The filter should be changed at the intervals recommended in the service schedule. However, if the car is used in a
severely contaminated environment, it may be necessary to change the filter more frequently.
