2012 VOLVO XC70 warning

01 Safety
Supplemental Restraint System (SRS)01

21 General information
Warning symbols in the instrument panel
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, a front passenger
occupant weight sensor, and inflatable cur-
tains. All of these systems are monitored by the
SRS control module. An SRS warning light in
the instrument panel (see the illustration) illu-
minates when the ignition is in modes I, II, or
III, and will normally go out after approximately
6 seconds if no faults are detected in the sys-
tem.
Where applicable, a text message will also be
displayed when the SRS warning light illumi-
nates. If this warning symbol is not functioningproperly, the general warning symbol illumi-
nates and a text message will be displayed.
See also page 76 and page 78 for more
information about indicator and warning sym-
bols.
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
insert the remote key into the ignition slot
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:
1. Switch off the ignition for at least
10 minutes and disconnect the battery.
2. Follow the instructions for manually
overriding the shiftlock system on page
116.

Front airbags
G018665
The front airbag systemThe 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.
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 com-
partment.
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 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 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.
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 pro-
longed exposure.
Should you have questions about any compo-
nent in the SRS system, please contact a
trained and qualified Volvo service technician

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.

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.
For child safety recommendations,see
page 37.
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 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 frontairbag 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
urgen-64 will be displayed in the informa-
tion display.
WARNING
If a fault in the system is detected and indi-
cated as described, be aware that the pas-
senger'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 quali-
fied 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 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.

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 in the event
of a collision anytime the system senses that a
person of adult size is sitting properly in the
front passenger's seat. The PASSENGER AIR-BAG 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 AIR-
BAG 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 per-
son'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 pas-
senger'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.
ModificationsIf 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 sys-
tems, please contact Volvo at:

1-800-663-8255WARNING
•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 occu-
pant 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 front, passenger's
side airbag.
