2008 VOLVO C70 service

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.

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.
28 01 Safety
Roll-over Protection System
Roll-over Protection system (ROPS)
ProCarManuals.com

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 Volvo service technician.
29 01 Safety
Crash mode
Driving after a collision
If the vehicle has been involved in a collision, the text CRASH MODE SEE MANUAL may appear in the information
display. This indicates that the vehicle's functionality has been reduced.
ProCarManuals.com

NOTE
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 systems, 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 function.
Restoring the vehicle to normal operating mode should only be done by a trained and qualified Volvo service
technician.
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:
1. Remove the ignition key.
2. Reinsert the key in the ignition switch. The vehicle will then attempt to reset CRASH MODE to normal mode.
3. 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 present 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 qualified Volvo service technician for
inspection/repairs.
30 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
