01 Safety

Occupant Weight Sensor (OWS)

Disabling the passenger's side front
airbag

G018346

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 33.

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 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.

01 Safety

Occupant Weight Sensor (OWS)

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 the

passenger's side front airbag is disabled (see
the following table).

Volvo 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 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:

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.

Modifications

If you are considering modifying your vehicle in
any way to accommodate a disability, for
example by altering or adapting the driver's or

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 34.

•

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

Side impact airbags – front seats only

G0201

Location of the side impact (SIPS) airbag

As 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 system

This 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 Safety

Door Mounted Inflatable Curtain system (DMIC)

G025425

The DMIC is a supplement to the structural side
impact protection. These inflatable curtains are
concealed in the upper section of both doors.

•

The Inflatable Curtain (DMIC) and the Side
Impact Airbag System (SIPS airbag) will
both deploy in certain side impacts.

•

DMIC deployment can occur regardless of
whether the power retractable hard top is
up or down.

•

If the inflatable curtain deploys, it remains
inflated for approximately 5 seconds.

WARNING

•

The DMIC 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 vehicle. It
only provides protection for the occu-
pants of the front seats.

•

There is a risk of injury if the driver or
front seat passenger leans on or against
the door panel when the DMIC deploys.

•

Never install or mount any equipment
on the insides of the doors, door pillars,
or side panels. This could impede the
function of the DMIC system.

•

Never try to open or repair any compo-
nents of the DMIC system. This should
be done only by a trained and qualified
Volvo service technician.

G025424

WARNING

In order for the DMIC to provide its best
protection, both front seat occupants
should sit in an upright position with the seat
belt properly fastened; adults using the seat
belt and children using the proper child
restraint system. Only adults should sit in
the front seats. Children must never be
allowed in the front passenger seat. See
page 34 for guidelines. Failure to follow
these instructions can result in injury to the
vehicle occupants in an accident.

01 Safety

Roll-over Protection system (ROPS)

Introduction

G020797

Deployed ROPS roll bars

The ROPS system consists of two roll bars
located behind the rear seat head restraints,
and a sensor that monitors the roll or pitch
angle of the vehicle.

If the vehicle rolls or pitches beyond a preset
angle, or in the event of a rear-end collision of
sufficient force, the roll bars are automatically
deployed (raised).

The ROPS system is designed to function
regardless of whether the power retractable
hard top is up or down. By design, the tops of
the roll bars are equipped with a point in order
to pierce the rear window if the top is up.

NOTE

If ROPS has deployed, the system should
be inspected by a trained and qualified
Volvo service technician.

WARNING

•

The rear seat of the Volvo C70 is
intended for two occupants, and only
two rear seat belts are provided. The
center section of the seat should never
be used to seat a passenger.

•

No objects should be placed over the
roll bars or behind the rear seat head
restraints.

•

All repairs or maintenance to the ROPS
system should only be performed by a
trained and qualified Volvo service tech-
nician.

01 Safety

Crash mode

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 the

fuel 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 MANUAL

has 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 vehicle

If damage to the vehicle is minor and there is
no fuel leakage, you may attempt to start the
vehicle. To do so:

Remove the ignition key or optional keyless
drive start control, see page 145.

Reinsert the key or start control in the igni-
tion switch. The vehicle will then attempt to
reset CRASH MODE to normal mode.

Try to start the vehicle.

Moving the vehicle

If 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

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 properly

restrained 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
41). 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 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.

01 Safety

Child safety

Automatic Locking Retractor/
Emergency Locking Retractor (ALR/
ELR)

To make child seat installation easier, each
seat belt (except for the driver's belt) is equip-
ped with a locking mechanism to help keep the
seat belt taut.

When attaching the seat belt to a child
seat:

Attach the seat belt to the child seat
according to the child seat manufacturer's
instructions.

Pull the seat belt out as far as possible.

Insert the seat belt latch plate into the
buckle (lock) in the usual way.

Release the seat belt and pull it taut around
the child seat.

A sound from the seat belt retractor will be
audible at this time and is normal. The belt will
now be locked in place. This function is auto-
matically disabled when the seat belt is
unlocked and the belt is fully retracted.

WARNING

Do not use child safety seats or child
booster cushions/backrests in the front
passenger's seat. We also recommend that
children who have outgrown these devices
sit in the rear seat with the seat belt properly
fastened.

Volvo's recommendations

Why does Volvo believe that no child should sit
in the front seat of a car? It's quite simple really.
A front airbag is a very powerful device
designed, by law, to help protect an adult.

Because of the size of the airbag and its speed
of inflation, a child should never be placed in
the front seat, even if he or she is properly bel-
ted or strapped into a child safety seat. Volvo
has been an innovator in safety for over sev-
enty-five years, and we'll continue to do our
part. But we need your help. Please remember
to put your children in the back seat, and
buckle them up.

Volvo has some very specific
recommendations:

•

Always wear your seat belt.

•

Airbags are a SUPPLEMENTAL safety
device which, when used with a three-
point seat belt can help reduce serious
injuries during certain types of accidents.

Volvo recommends that you do not dis-
connect the airbag system in your vehicle.

•

Volvo strongly recommends that everyone
in the vehicle be properly restrained.

•

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.

•

Drive safely!
