Occupant Weight Sensor (OWS)01

29
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 thepassenger'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. 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 aperson 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 seatback 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.
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

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.

01 Safety
Side impact protection airbags 01
32
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)01
33
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.
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 39 for guidelines. Failure to follow
these instructions can result in injury to the
vehicle occupants in an accident.

01 Safety
Whiplash Protection System 01
34
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.

Certain components in the WHIPS sys-
tem may need to be replaced.
•Do not attempt to service any compo-
nent in the WHIPS system yourself.
G020125
WARNING
Boxes, suitcases, etc. wedged behind the
front seats could impede the function of the
WHIPS system.

01 Safety
Roll-over Protection system (ROPS) 01
36
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 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 149.
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.
