SRS warning light
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, 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,
or III, 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 illuminates. If
this warning symbol is not func-
tioning properly, the general warn-
ing symbol illuminates and a text message 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
an authorized 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 P (Park) to
the N(Neutral) position.

01 Safety
Occupant Weight Sensor 01

Disabling the passenger's side front
airbag
G027050
Occupant Weight Sensor (OWS) indicator light
Volvo 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. For child safety recommen-
dations, 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 (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
The PASSENGER AIRBAG OFF indicator
lamp will illuminate for a short period of time
when the ignition is turned on to confirm it
is functional. When the front passenger's
seat is not occupied (empty seat) or in the
event that the passenger's side front airbag
is enabled (may inflate), the PASSENGER
AIRBAG OFF indicator lamp will be off.
However, if a fault is detected in the system:
•The OWS indicator light will stay on
•The SRS warning light (see page 23) 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
indicated as explained, be aware that
the passenger's side front airbag will
not deploy in the event of a collision.
•In this case, the safety systems and
Occupant Weight Sensor should be
inspected by a trained and qualified
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 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 willilluminate and stay on to remind you that the
passenger'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.In
rare situations when the seat belt is not properly fastened,
some child restraints may not be detected by the OWS
because there is very little weight on the vehicle seat cush-
ion. In these cases the passenger's side front airbag may be
disabled, but the PASSENGER AIRBAG OFF indicator lamp
will not be lit. Do not assume that the passenger's side front
airbag is disabled unless the PASSENGER AIRBAG OFFindicator lamp is lit. Make sure the child restraint is properly
installed (turn the vehicle off, remove the child restraint from
the vehicle and reinstall the restraint following the child
restraint manufacturer's instructions) and that the
PASSENGER AIRBAG OFF indicator lamp is on, or 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
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 seat back 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.

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 front passenger's
side 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 38).
•No objects should be placed under the
front passenger's seat. This could inter-
fere with the OWS system's function.
