After refueling, close the fuel filler cap by turning it clockwise until it clicks into place. If this cap is not closed tightly
or if the engine is running when the car is refueled, the Malfunction Indicator Lamp ("Check Engine" light) may
indicate a fault.
Points to keep in mind
Before you operate your vehicle for the first time, please familiarize yourself with the new-engine oil consumption
information on page 205
. You should also be familiar with the information found in the chapters "Instruments and
controls," and "Starting and driving."
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 vehicle for
ready access.
Do not export your Volvo to another country before investigating that country's applicable safety and emission
control 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 requirements. 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.
WARNING
If your vehicle is involved in an accident, unseen damage may affect its driveability and safety.

7 Introduction
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 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 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 and cleaner

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
ProCarManuals.com

17 01 Safety
Supplemental Restraint System
Supplemental Restraint System (SRS)
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 pretensioners, 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) 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 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 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.
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:
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 Park ( P) to the Neutral ( N) position. See page 145 for information on manually

overriding the shiftlock system.
18 01 Safety
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 surrounded by the airbags, and deceleration sensors that activate 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 pretensioners 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.
WARNING
The airbags in the vehicle are designed to be a SUPPLEMENT to-not a replacement for-the three-point seat belts.
ProCarManuals.com

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.
19 01 Safety
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
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 collision where deployment occurs, the
airbags and seat belt pretensioners 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 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 airbags are triggered at partial capacity. If the impact is more severe, the 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:

WARNING
Do not use child safety seats or child booster cushions/backrests in the front passenger's seat. We also recommend
that occupants under 4 feet 7 inches (140 cm) in height who have outgrown these devices sit in the rear seat with the
seat belt fastened
1.
Never drive with the airbags deployed. The fact that they hang out can impair the steering of your vehicle. 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.
1See also the Occupant Weight Sensor information on page 21.
20 01 Safety
Front airbags
WARNING
ProCarManuals.com

Children must never be allowed in the front passenger's 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 passenger -side front
airbag. See page 32
for guidelines.
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.
WARNING
No objects or accessory equipment, e.g. dashboard covers, may be placed on, attached to, or installed near the air
bag hatch (the area above the glove compartment) or the area affected by airbag deployment (see the illustration on
page 18
).
There should be no loose articles, e.g. coffee cups, on the floor, seat, or dashboard area.
Never try to open the airbag cover on the steering wheel or the passenger's side dashboard. This should only be
done by a trained and qualified Volvo service technician.
Failure to follow these instructions can result in injury to the vehicle occupants.
21 01 Safety
Occupant Weight Sensor (OWS)
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 rear
ProCarManuals.com

seat of any vehicle 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 recommendations beginning on page
30.
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 (will not 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 passenger'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 manufacturer'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 17) will come on and stay on
The message PASS. AIRBAG OFF SERVICE URGENT will be displayed in the information display.
22 01 Safety
Occupant Weight Sensor (OWS)
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.
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.
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 system's function.
ProCarManuals.com

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 the passenger's side front airbag is disabled (see the following table).
1Volvo 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 airbag, 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:
Turn the vehicle off and ask the person to place the seatback in an upright position.
Have the person sit upright in the seat, centered on the seat cushion, with the person's legs comfortably extended.
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 passenger's frontal airbag.
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.
Modifications
If you are considering modifying your vehicle in any way to accommodate a disability, for example by altering or
adapting the driver's or front passenger's seat(s) and/or airbag systems, please contact Volvo at:
