2006 VOLVO S80 belt

Occupant Weight Sensor (OWS) indicator light
Disabling the passenger's side front airbag
Volvo recommends that ALL occupants (adults and children) shorter than four feet seven 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 21
.
The passenger's side front airbag is automatically enabled/disabled by the Occupant Weight Sensor (OWS), a system
that monitors the weight of the person or object in the front passenger's seat. The system consists of a silicone-filled
bag located under the padding in the front passenger's seat cushion, a control module located under this seat, and a seat
belt tension sensor, located on the outboard side of the seat.
The OWS system continuously monitors the pressure on the front passenger's seat cushion and the tension applied to
the seat belt. Based on this data, OWS assesses the weight of the occupant or object in the front passenger's seat. This
information is transmitted to the SRS system control module, which enables or disables the passenger's side front
airbag accordingly, as indicated in the table to the right.
If the system is functioning normally, the status of the front passenger's side airbag (enabled/ disabled) will be shown
by the OWS indicator light as explained in the table to the right. The OWS indicator light is separate and in addition to
the SRS warning light in the instrument panel.
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 and then go out.
However, if a fault is detected in the system:
The OWS indicator light will stay on
The SRS warning light (see page 5) 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 explained on the previous page, be aware that the passenger's
side front airbag will not deploy in the event of a collision. In this case, the safety systems and Occupant Weight
Sensor should be inspected by an authorized Volvo retailer as soon as possible.
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:

1-800-663-8255 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!
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 authorized 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.
pg. 11 Occupant Weight Sensor (OWS)
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 ALR/ELR seat belt
(see page 21
).
No objects should be placed under the front passenger's seat. This could interfere with the OWS system's function.

Turn signal indicator - trailer (certain models)
If you are towing a trailer, this light will flash simultaneously with the turn signals on the trailer. If the light does not
flash when signaling, neither the trailer's turn signals nor the car's turn signals are functioning.

Seat belt reminder
This symbol lights up to indicate that the driver has not fastened his/her seat belt.

Tire pressure warning light

for more information on this function.
Supplemental Restraint System (SRS)
If this light comes on while the car is being driven, or remains on for longer than approximately 10 seconds after the
car has been started, the SRS system's diagnostic functions have detected a fault in a seat belt lock or tensioner, a front
airbag, side impact airbag, and/or an inflatable curtain. Have the system(s) inspected by a trained and qualified Volvo
service technician as soon as possible.

From the rear seat, fold down the left section of the backrest slightly*.
Release the flap by pushing the catch (located on the rear side of the backrest) upward and pulling the flap forward.
Return the backrest to the upright position.
* If your car is equipped with the optional integrated child booster cushion, this cushion must be folded down before
you fold down the backrest (see page 15
).

additional information.
WARNING!
Never carry a cell phone that is switched on while refueling your vehicle. If the phone rings, this may cause a spark
that could ignite gasoline fumes, resulting in fire and injury.
CAUTION:
Do not refuel with the engine running *. Turn the ignition off or to position I. If the ignition is on, an incorrect
reading could occur in the fuel gauge.
After refueling, close the fuel filler cap by turning it clockwise until it clicks into place *.
Allow for fuel expansion by not overfilling the tank. Overfilling could also cause damage to the emission control
systems.
Avoid spilling gasoline during refueling. In addition to causing damage to the environment, gasolines containing
alcohol can cause damage to painted surfaces, which may not be covered under the New Vehicle Limited Warranty.
Do not use gasolines containing methanol (methyl alcohol, wood alcohol). This practice can result in vehicle
performance deterioration and can damage critical parts in the fuel system. Such damage may not be covered under the
New Vehicle Limited Warranty.
* If the fuel filler cap is not closed tightly or if the engine is running when the car is refueled, the Check Engine
Light (malfunction indicator lamp) may indicate a fault.
However, your vehicle's performance will not be affected. Use only Volvo original or approved fuel filler caps.
pg. 77 Starting the engine
Starting the engine
1. Fasten the seat belt.
WARNING!
Before starting, check that the seat, steering wheel and mirrors are adjusted properly. Make sure the brake pedal can
be depressed completely. Adjust the seat if necessary. See page 54
.
2. Apply the parking brake, if not already set. The gear selector is locked in the (P)ark position (SHIFTLOCK).
3. Without touching the accelerator pedal, turn the ignition key* to the starting position. Allow the starter to operate
for up to 5 seconds (turbo: 10 seconds). Release the key as soon as the engine starts. If the engine fails to start, repeat
this step.
NOTE: On certain models, when the car is started, idle speed may be noticeably higher than normal for a short period,
depending on the temperature of the engine.
This has been done to help bring components in the emission control system to their normal operating temperature as
quickly as possible, which enables them to function normally.
For cold starts at altitudes above 6000 ft (1800 meters), depress the accelerator pedal halfway and turn the key to the
starting position. Release the pedal slowly when the engine starts.
4. To release the gear selector from the (P)ark position, the engine must be running (or the ignition key must be in
position II) and the brake pedal must be depressed. While keeping firm pressure on the brake pedal, release the parking
brake.
5. Select the desired gear. The gear engages after a very slight delay which is especially noticeable when selecting R.
