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.
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 (OWS)
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.
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.
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.
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.
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 front passenger's seat(s) and/or airbag systems, please contact Volvo at:

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.
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.

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
used properly. However, children could be endangered in a crash if the child restraints are not properly secured in the
vehicle. 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 ejected 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 governing how and where children should be carried in a car. Find out the
regulations existing in your state or province. Recent accident statistics have shown that children are safer in rear
seating positions than front seating positions when properly restrained. A child restraint system 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 Canada, 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 information.
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 40
). 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 cushion (not available in Canada) can be obtained from your Volvo retailer for
children weighing 33 - 80 lb. (15 - 36 kg) and 38-54 inches (97 - 137 cm) in height.

Child restraint systems
Child restraints
There are three main types of child restraint systems: infant seats, convertible seats, and booster cushions. They are
classified according to the child's age and size.
The following section provides general information on securing a child restraint using a three-point seat belt. Refer to
pages 41-42
for information on securing a child restraint using ISOFIX lower anchors and/or top tether anchorages.
WARNING
A child seat should never be used in the front passenger seat of any vehicle with a front passenger airbag - not even
if the "Passenger airbag off" symbol near the rear-view mirror is illuminated (on vehicles equipped with Occupant
Weight Sensor). If the severity of an accident were to cause the airbag to inflate, this could lead to serious injury or
death to a child seated in this position.

Child restraint systems
WARNING
When not in use, keep the child restraint system secured or remove it from the passenger compartment to help
prevent it from injuring passengers in the event of a sudden stop or collision.
A small child's head represents a considerable part of its total weight and its neck is still very weak. Volvo
recommends that children up to age 4 travel, properly restrained, facing rearward. In addition, Volvo recommends
that children should ride rearward facing, properly restrained, as long as possible.
