Supplemental Restraint System01

25 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

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.

G018082
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. See also the child safety rec-
ommendations on page 38.
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 23) will
come on and stay on
The message
PASS. AIRBAG OFF SERVICE
URGENTwill be displayed in the information
display.

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 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 39.
•No objects should be placed under the
front passenger's seat. This could inter-
fere with the OWS system's function.

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.

WARNING
In order for the VIC to provide its best pro-
tection, both front seat occupants and both
outboard rear seat occupants should sit in
an upright position with the seat belt prop-
erly fastened; adults using the seat belt and
children using the proper child restraint sys-
tem. Only adults should sit in the front seats.
Children must never be allowed in the front
passenger's seat, see page 39 for guide-
lines. Failure to follow these instructions can
result in injury to the vehicle occupants in an
accident.

01 Safety
Whiplash Protection System01

35 Whiplash Protection System (WHIPS) – front seats only
G020347
The WHIPS system consists of specially
designed hinges and brackets on the front seat
backrests designed to help absorb some of the
energy generated in a collision from the rear
(when the vehicle is "rear-ended").
In the event of a collision of this type, the hinges
and brackets of the front seat backrests are
designed to change position slightly to allow
the backrest/head restraint to help support the
occupant's head before moving slightly rear-
ward. This movement helps absorb some of
the forces that could result in whiplash.WARNING
•The WHIPS system is designed to sup-
plement the other safety systems in
your car. For this system to function
properly, the three-point seat belt must
be worn. Please be aware that no sys-
tem can prevent all possible injuries that
may occur in an accident.
•The WHIPS system is designed to func-
tion in certain collisions from the rear,
depending on the crash severity, angle
and speed.
WARNING
•Occupants in the front seats must never
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.
•If your car has been involved in a rear-
end collision, the front seat backrests
must be inspected by a trained and
qualified Volvo service technician, even
if the seats appear to be undamaged.

01 Safety
Crash mode01
37 Driving after a collision
G026363
If the vehicle has been involved in a collision,
the text CRASH MODE SEE MANUAL may
appear in the information display. This indi-
cates that the vehicle's functionality has been
reduced.
This text can only be shown if the display is
undamaged and the vehicle's electrical system
is intact.
CRASH MODE is a feature that is triggered if
one or more of the safety systems (for example,
front or side airbags, an inflatable curtain, or
one or more of the seat belt pretensioners) has
deployed. The collision may have damaged an
important function in the vehicle, such as thefuel lines, sensors for one of the safety sys-
tems, the brake system, etc.
WARNING
•Never attempt to repair the vehicle
yourself or to reset the electrical system
after the vehicle has displayed
CRASH
MODE SEE MANUAL. This could
result in injury or improper system func-
tion.
•Restoring the vehicle to normal operat-
ing mode should only be done by a
trained and qualified Volvo service tech-
nician.
•After CRASH MODE SEE MANUALhas been displayed, if you detect the
odor of fuel vapor, or see any signs of
fuel leakage, do not attempt to start the
vehicle. Leave the vehicle immediately.
Attempting to start the vehicleIf damage to the vehicle is minor and there is
no fuel leakage, you may attempt to start the
vehicle. To do so:
1. Remove the ignition key or optional keyless
drive start control, see page 150.
2. Reinsert the key or start control in the igni-
tion switch. The vehicle will then attempt to
reset CRASH MODE to normal mode.3. Try to start the vehicle.
Moving the vehicleIf the electrical system is able to reset system
status to normal (CRASH MODE SEE
MANUAL will no longer be displayed), the
vehicle may be moved carefully from its pres-
ent position, if for example, it is blocking traffic.
It should, however, not be moved farther than
is absolutely necessary.
WARNING
Even if the vehicle appears to be drivable
after CRASH MODE has been set, it should
not be driven or towed (pulled by another
vehicle). There may be concealed damage
that could make it difficult or impossible to
control. The vehicle should be transported
on a flatbed tow truck to a trained and quali-
fied Volvo service technician for inspection/
repairs.

01 Safety
Child safety 01
38
Children should be seated safely
Volvo recommends the proper use of restraint
systems for all occupants including children.
Remember that, regardless of age and size, a
child should always be properly restrained in a
car.
Your car is also equipped with ISOFIX/LATCH
attachments, which make it more convenient
to install child seats.
Some restraint systems for children are
designed to be secured in the vehicle by lap
belts or the lap portion of a lap-shoulder belt.
Such child restraint systems can help protect
children in cars in the event of an accident only
if they are used properly. However, children
could be endangered in a crash if the child
restraints are not properly secured in the vehi-
cle. Failure to follow the installation instructions
for your child restraint can result in your child
striking the vehicle's interior in a sudden stop.
Holding a child in your arms is NOT a suitable
substitute for a child restraint system. In an
accident, a child held in a person's arms can
be crushed between the vehicle's interior and
an unrestrained person. The child could also be
injured by striking the interior, or by being ejec-
ted from the vehicle during a sudden maneuver
or impact. The same can also happen if the
infant or child rides unrestrained on the seat.
Other occupants should also be properlyrestrained to help reduce the chance of injuring
or increasing the injury of a child.
All states and provinces have legislation gov-
erning how and where children should be car-
ried in a car. Find out the regulations existing
in your state or province. Recent accident sta-
tistics have shown that children are safer in rear
seating positions than front seating positions
when properly restrained. A child restraint sys-
tem can help protect a child in a vehicle. Here's
what to look for when selecting a child restraint
system:
•It should have a label certifying that it
meets applicable Federal Motor Vehicle
Safety Standards (FMVSS 213) – or in Can-
ada, CMVSS 213.
•Make sure the child restraint system is
approved for the child's height, weight and
development – the label required by the
standard or regulation, or instructions for
infant restraints, typically provide this infor-
mation.
•In using any child restraint system, we urge
you to carefully look over the instructions
that are provided with the restraint. Be sure
you understand them and can use the
device properly and safely in this vehicle.
A misused child restraint system can result
in increased injuries for both the infant or
child and other occupants in the vehicle.When a child has outgrown the child safety
seat, you should use the rear seat with the
standard seat belt fastened. The best way to
help protect the child here is to place the child
on a cushion so that the seat belt is properly
located on the hips (see the illustration on page
46). Legislation in your state or province may
mandate the use of a child seat or cushion in
combination with the seat belt, depending on
the child's age and/or size. Please check local
regulations.
A specially designed and tested booster cush-
ion and backrest can be obtained from your
Volvo retailer.
USA: for children weighing 33–80 lbs. (15–
36 kg) and 38–54 inches (97–137 cm) in height
Canada: for children weighing 40–80 lbs. (18–
36 kg) and 40–54 inches (102–137 cm) in height
WARNING
Do not use child safety seats or child
booster cushions/backrests in the front
passenger's seat. We also recommend that
children under 4 feet 7 inches (140 cm) in
height who have outgrown these devices sit
in the rear seat with the seat belt fastened.
