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 74 and page 76 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
112.
Please be aware that overriding the shiftlock
system does not release the steering wheel
lock.

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
urgent will be displayed in the information
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.
