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
23 01 Safety
Occupant Weight Sensor (OWS)
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 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.
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.
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).

restraint system. Only adults should sit in the front seats. Children must never be allowed in the front passenger's
seat. See page 32 for guidelines. Failure to follow these instructions can result in injury to the vehicle occupants in
an accident.
28 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.

See the following pages for additional information.
4. Information display
The display presents information and warning messages, the ambient temperature, etc. When the ambient temperature is
between 23° and 36°F (-5° and +2°C), a snowflake symbol is shown in the display. This symbol serves as a warning for
possible slippery road surfaces. Please note that this symbol does not indicate a fault with your car. At low speeds, or
when the vehicle is not moving, the temperature readings may be slightly higher than the actual ambient temperature.
5. Information symbol
See the following pages for additional information.
6. Turn signal, right
7. Tachometer
The tachometer shows engine speed in thousands of revolutions per minute (rpm). Do not drive continuously with the
needle in the red area of the dial, which indicates maximum allowable engine rpm range. Instead, shift to a higher gear or
slow the vehicle down. The engine management system will automatically prevent excessively high engines speeds. This
will be noticeable as a pronounced unevenness in engine speed.

The indicator and warning symbols light
1 up when you turn the ignition key or the optional keyless drive start control to
the driving position (position II) before starting. This shows that the symbols are functioning.
When the engine starts, all symbols go out. If the engine is not started within 5 seconds, all of the symbols except
CHECK ENGINE and will go out. Certain symbols may not have their functions illustrated, depending on the car's
equipment.
The PARK BRAKE symbol will not go out until the parking brake has been released.
1On certain engines, the symbol for low oil pressure is not used. Instead, a text warning is provided in the information display, see also page 203.
Symbols in the center of the instrument panel
Warning symbol
The red warning symbol lights up to indicate a fault that could affect the car's drivability. This symbol illuminates when
the vehicle is traveling at speeds above 5 mph (7 km/h). A text explaining the nature of the fault will also be shown in the
information display. The symbol and accompanying text will remain on until the fault has been corrected. This symbol

may also light up in combination with other indicator or warning symbols.
If the red warning symbol lights up:
1. Stop the vehicle as soon as possible in a suitable location.
2. Read the message in the information display.
3. Follow the instructions provided, or contact a trained and qualified Volvo service technician. Erase the message by
pressing READ (see page 56
).
Information symbol
The yellow information symbol lights up to alert the driver to a message in the information display. This symbol
illuminates when the vehicle is traveling at speeds below 5 mph (7 km/h).
The message can be erased by pressing the READ button (see page 56
), or will disappear automatically (the length of
time required for the message to disappear varies, depending on the function indicated).
When the message "TIME FOR REGULAR SERVICE" is displayed, the text can be erased and the information symbol
light can be turned off by pressing the READ button. The text will disappear and the symbol light will go out
automatically after two minutes.

Symbols - left side

1. Malfunction indicator light
As you drive, a computer called On-Board Diagnostics II (OBDII) monitors your car's engine, transmission, electrical and
emission systems.
The CHECK ENGINE light will light up if the computer senses a condition that potentially may need correcting. When
this happens, please have your vehicle checked by a trained and qualified Volvo service technician as soon as possible.
A CHECK ENGINE light may have many causes. Sometimes, you may not notice a change in your car's behavior. Even
so, an uncorrected condition could hurt fuel economy, emission controls, and drivability. Extended driving without
correcting the cause could even damage other components in your car.
NOTE
Canadian models are equipped with the second symbol.
2. Anti-lock Brake system (ABS)
If the warning light comes on, there is a malfunction of the ABS system (the standard braking system will still function).
The vehicle should be driven to a trained and qualified Volvo service technician for inspection. See page 148
for
additional information.
NOTE
Canadian models are equipped with the second symbol.
3. Rear fog light
This symbol indicates that the rear fog light (located in the driver's side taillight cluster) is on.
