SRS warning lightAs 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,
orIII, 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
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 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 151,
for information on manually overriding
the shiftlock system.

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.
G015167
Location of the passenger's side front airbagAs the movement of the seats' occupants com-
presses the airbags, some of the gas is expel-
led 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 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.

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

•
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 pro-
longed exposure.

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.
•
There should be no loose articles, e.g.
coffee cups, on the floor, seat, or dash-
board 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.

01 SafetyOccupant Weight Sensor (OWS)
0126
Disabling the passenger's side front
airbag

G018082
Occupant Weight Sensor (OWS) indicator lightVolvo 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.

Occupant Weight Sensor (OWS)
01``27
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 thesystem senses that a person of adult size is
sitting properly in the front passenger's seat.
ThePASSENGER 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.

WARNING
•
No objects that add to the total weight
on the seat should be placed on the
front passenger's seat. If a child is
seated in the front passenger's seat
with any additional weight, this extra
weight could cause the OWS system to
enable the airbag, which might cause it
to deploy in the event of a collision,
thereby injuring the child.
•
The seat belt should never be wrapped
around an object on the front passeng-
er's seat. This could interfere with the
OWS system's function.
•
The front passenger's seat belt should
never be used in a way that exerts more
pressure on the passenger than normal.
This could increase the pressure exer-
ted on the weight sensor by a child, and
could result in the airbag being enabled,
which might cause it to deploy in the
event of a collision, thereby injuring the
child.
WARNING
Keep the following points in mind with
respect to the OWS system. Failure to follow
these instructions could adversely affect the
system's function and result in serious injury
to the occupant of the front passenger's
seat:•
The full weight of the front seat passen-
ger should always be on the seat cush-
ion. The passenger should never lift
him/herself off the seat cushion using
the armrest in the door or the center
console, by pressing the feet on the
floor, by sitting on the edge of the seat
cushion, or by pressing against the
backrest in a way that reduces pressure
on the seat cushion. This could cause
OWS to disable the passenger's side
front airbag.
•
Do not place any type of object on the
front passenger's seat in such a way
that jamming, pressing, or squeezing
occurs between the object and the front
seat, other than as a direct result of the
correct use of the Automatic Locking
Retractor/Emergency Locking Retrac-
tor (ALR/ELR) seat belt, see page 36.
•
No objects should be placed under the
front passenger's seat. This could inter-
fere with the OWS system's function.

01 Safety
Side impact protection airbags
0129 Side impact airbags – front seats only
G020118
Location of the side impact (SIPS) airbagAs an enhancement to the structural side
impact protection built into your car, the car is
also equipped with Side Impact Protection
System (SIPS) airbags.
The SIPS airbag system is designed to help
increase occupant protection in the event of
certain side impact collisions. The SIPS air-
bags are designed to deploy only during cer-
tain side-impact collisions, depending on the
crash severity, angle, speed and point of
impact.
G025315
SIPS airbag deployment
NOTE
SIPS airbag deployment (one airbag) occurs
only on the side of the vehicle affected by
the impact. The airbags are not designed to
deploy in all side impact situations.Components in the SIPS airbag systemThis SIPS airbag system consists of gas gen-
erators and side airbag modules built into the
outboard sides of both front seat backrests.
WARNING
•
The SIPS airbag system is a supple-
ment to the structural Side Impact Pro-
tection System and the three-point seat
belt system. It is not designed to deploy
during collisions from the front or rear of
the car or in rollover situations.
•
The use of seat covers on the front seats
may impede SIPS airbag deployment.
•
No objects, accessory equipment or
stickers may be placed on, attached to
or installed near the SIPS airbag system
or in the area affected by SIPS airbag
deployment.
•
Never try to open or repair any compo-
nents of the SIPS airbag system. This
should be done only by a trained and
qualified Volvo service technician.
•
In order for the SIPS airbag to provide
its best protection, both front seat
occupants should sit in an upright posi-
tion with the seat belt properly fastened.
•
Failure to follow these instructions can
result in injury to the occupants of the
vehicle in the event of an accident.

01 SafetyVolvo Inflatable Curtain (VIC)
0130
The Volvo Inflatable Curtain system
G015265
This system consists of inflatable curtains
located along the sides of the roof liners,
stretching from the center of both front side
windows to the rear edge of the rear side door
windows. It is designed to help protect the
heads of the occupants of the front seats and
the occupant of the outboard rear seating posi-
tions in certain side impact collisions.
In certain side impacts, both the Inflatable Cur-
tain (VIC) and the Side Impact Airbag System
(SIPS airbag) will deploy. The VIC and the SIPS
airbag deploy simultaneously.
NOTE
If the inflatable curtain deploys, it remains
inflated for approximately 3 seconds.
WARNING
•
The VIC system is a supplement to the
Side Impact Protection System. It is not
designed to deploy during collisions
from the front or rear of the car or in roll-
over situations.
•
Never try to open or repair any compo-
nents of the VIC system. This should be
done only by a trained and qualified
Volvo service technician.
•
Never hang heavy items from the ceiling
handles. This could impede deployment
of the Inflatable curtain.
