2008 VOLVO V70 Owners Manual

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
back seat of any vehicle with a front passenger side airbag, and be properly restrained for their size and weight. See
also the child safety recommendations 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 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.
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 18) will come on and stay on
The message PASS. AIRBAG OFF SERVICE URGENT will be displayed in the information display.
WARNING
If a fault in the system is detected and indicated as described, 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.
23 01 Safety
Safety in the passenger compartment
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 system's function.
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.
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 front, passenger's side 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 Retractor (ALR/ELR) seat belt (see page 33
).
No objects should be placed under the front passenger's seat. This could interfere with the OWS system's function.

Side impact airbags - front seats only
As an enhancement to the structural side impact protection built into your vehicle, it 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.

the outboard sides of both front seat backrests, and electronic sensors/wiring.
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 vehicle 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.

Volvo Inflatable Curtain (VIC)
The Volvo Inflatable Curtain system
This system consists of inflatable curtains located along the sides of the roof liners, stretching from the center of both
front side windows to the rear edge of the rear side door windows. It is designed to help protect the heads of the
occupants of the front seats and the occupant of the outboard rear seating positions in certain side impact collisions.
In certain side impacts, both the Inflatable Curtain (VIC) and the Side Impact Airbag System (SIPS airbag) will
deploy. The VIC and the SIPS airbag deploy simultaneously.
NOTE
If the inflatable curtain deploys, it remains inflated for approximately 3 seconds.
ProCarManuals.com

WARNING
The VIC 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 or in rollover situations.
Never try to open or repair any components of the VIC system. This should be done only by a trained and
qualified Volvo service technician.
Never hang heavy items from the ceiling handles. This could impede deployment of the Inflatable Curtain.
The cargo area and rear seat should not be loaded to a level higher than 2 in. (5 cm) below the upper edge of the
rear side windows. Objects placed higher than this level could impede the function of the Volvo Inflatable Curtain.
WARNING
In order for the VIC to provide its best protection, both front seat occupants and both outboard rear 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 33
for guidelines. Failure to follow these instructions can result in injury to the vehicle
occupants in an accident.

Whiplash Protection System - WHIPS
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).
ProCarManuals.com

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 vehicle. 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.
WARNING
If your vehicle 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
system may need to be replaced.
Do not attempt to service any component in the WHIPS system yourself.
29 01 Safety
Safety in the passenger compartment
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.
ProCarManuals.com

WARNING
Any contact between the front seat backrests and the folded rear seat or a rear-facing child seat could impede the
function of the WHIPS system. If the rear seat is folded down, the occupied front seats must be adjusted forward so
that they do not touch the folded rear seat.
30 01 Safety
Crash mode
Driving after a collision
If the vehicle has been involved in a collision, the text SAFETY MODE SEE MANUAL may appear in the
information display. This indicates that the vehicle's functionality has been reduced.
NOTE
This text can only be shown if the display is undamaged and the vehicle's electrical system is intact.
Safety mode is a feature that is triggered if one or more of the safety systems (e.g. 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
SAFETY MODE SEE MANUAL. This could result in injury or improper system function.
Restoring the vehicle to normal operating status should only be done by a trained and qualified Volvo service
technician.
After SAFETY 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.
