2009 VOLVO S40 light

01 Safety
Occupant Weight Sensor (OWS)
01``27
WARNING
If a fault in the system is detected and indi-
cated as explained on the preceding page,
be aware that the passenger's side front air-
bag 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 techni-
cian 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 sys-
tem'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 thepassenger's side front airbag is disabled (see
the following table).

AVolvo 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 air-
bag, move the child restraint to the rear seat.The OWS is designed to enable (may inflate)
the passenger's side front airbag anytime thesystem senses that a person of adult size is
sitting properly in the front passenger's seat.
ThePASSENGER 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:
1. Turn the vehicle off and ask the person to
place the seatback in an upright position.
2. Have the person sit upright in the seat,
centered on the seat cushion, with the per-
son's legs comfortably extended.
3. 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 pas-
senger's frontal airbag.
4.
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.
ModificationsIf you are considering modifying your vehicle in
any way to accommodate a disability, for

01 SafetyWhiplash Protection System
0132
Whiplash Protection System (WHIPS) – front seats only
G020347
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 "rearended").
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 rear-
ward. This movement helps absorb some of
the forces that could result in whiplash.
WARNING
•
The WHIPS system is designed to sup-
plement 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 sys-
tem can prevent all possible injuries that
may occur in an accident.
•
The WHIPS system is designed to func-
tion 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.
•
If your car 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.

for additional information.Information display – The display presents
information and warning messages, the
ambient temperature, clock, etc. When the
ambient temperature is between 23 °F and
36 °F (–5 °C and +2 °C), a snowflake sym-
bol 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 car is not moving,the temperature readings may be slightly
higher than the actual ambient tempera-
ture.

pages for additional information.Turn signal, rightTachometer – 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 exces-sively high engines speeds. This will be
noticeable as a pronounced unevenness in
engine speed.

1. Malfunction indicator light
As you drive, a computer called
On-Board Diagnostics II (OBDII)
monitors your car's engine, trans-
mission, electrical and emission
systems.
TheCHECK ENGINE light will light
up if the computer senses a condition that
potentially may need correcting. When this
happens, please have your car checked by a
trained and qualified Volvo service technician
as soon as possible.
CHECK
ENGINEACHECK ENGINE light may have many cau-
ses. Sometimes, you may not notice a changein your car's behavior. Even so, an uncorrected
condition could hurt fuel economy, emission
controls, and drivability. Extended driving with-
out 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).

qualified Volvo service technician for inspec-
tion, see page 153 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.
