2008 VOLVO C70 Owners Manual

WARNING
Children must never be allowed in the front passenger's seat. 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 passenger -side front
airbag. See page 32
for guidelines.
Occupants in the front passenger's seat must never sit on the edge of the seat, sit leaning toward the instrument
panel or otherwise 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.
Feet must be on the floor, e.g., not on the dash, seat or out of the window.
WARNING
No objects or accessory equipment, e.g. dashboard covers, may be placed on, attached to, or installed near the air
bag hatch (the area above the glove compartment) or the area affected by airbag deployment (see the illustration on
ProCarManuals.com

page 18).
There should be no loose articles, e.g. coffee cups, on the floor, seat, or dashboard area.
Never try to open the airbag cover on the steering wheel or the passenger's side dashboard. This should only be
done by a trained and qualified Volvo service technician.
Failure to follow these instructions can result in injury to the vehicle occupants.
21 01 Safety
Occupant Weight Sensor
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 rear
seat of any vehicle 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 recommendations beginning on page
30.
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 passenger'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 manufacturer'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.
ProCarManuals.com

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 17) will come on and stay on
The message PASS. AIRBAG OFF SERVICE URGENT will be displayed in the information display.
22 01 Safety
Occupant Weight Sensor
WARNING
If a fault in the system is detected and indicated as explained on the preceding page, be aware that the passenger'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 qualified Volvo service technician as soon as possible.
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 system'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).
1Volvo 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 airbag, 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.
ProCarManuals.com

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 person'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 passenger'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.

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 passenger'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 exerted 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 passenger should always be on the seat cushion. 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.
ProCarManuals.com

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 Retractor (ALR/ELR) seat belt (see page 32
).
No objects should be placed under the front passenger's seat. This could interfere with the OWS system's function.
24 01 Safety
Side impact protection airbags
Side impact airbags (SIPS) - front seats only
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 airbags are designed to deploy only during certain side-impact collisions, depending on the crash severity,
angle, speed and point of impact.
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 generators and side airbag modules built into the outboard sides of both front
seat backrests.
ProCarManuals.com

WARNING
The SIPS airbag system is a supplement to the structural Side Impact Protection 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 components 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
position 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.
25 01 Safety
Door mounted inflatable curtains
Door Mounted Inflatable Curtain system (DMIC)
The DMIC is a supplement to the structural side impact protection. These inflatable curtains are concealed in the upper
section of the driver and passenger doors.
The Inflatable Curtain (DMIC) and the Side Impact Airbag System (SIPS-bag) will both deploy in certain side
impacts.
NOTE
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 occupants 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.
ProCarManuals.com

Never try to open or repair any components of the DMIC system. This should be done only by a trained and
qualified Volvo service technician.
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 32
for
guidelines. Failure to follow these instructions can result in injury to the vehicle occupants in an accident.
26 01 Safety
Whiplash Protection System
Whiplash Protection System (WHIPS) - front seats only
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
rearward. This movement helps absorb some of the forces that could result in whiplash.
WARNING
The WHIPS system is designed to supplement 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 system can prevent all possible injuries that
may occur in an accident.
The WHIPS system is designed to function 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.
27 01 Safety
Whiplash Protection System
WARNING
If your car has been involved in a rearend 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
system may need to be replaced.
Do not attempt to service any component in the WHIPS system yourself.
WARNING
Boxes, suitcases, etc. wedged behind the front seats could impede the function of the WHIPS system.
If the rear seat backrests are folded down, cargo must be secured to prevent it from sliding forward against the
front seat backrests in the event of a collision from the rear. This could interfere with the action of the WHIPS
system.
