01 Safety
Occupant Weight Sensor 01
26
WARNING
•If a fault in the system is detected and
indicated as explained, 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 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 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 willilluminate and stay on to remind you that the
passenger'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.In
rare situations when the seat belt is not properly fastened,
some child restraints may not be detected by the OWS
because there is very little weight on the vehicle seat cush-
ion. In these cases the passenger's side front airbag may be
disabled, but the PASSENGER AIRBAG OFF indicator lamp
will not be lit. Do not assume that the passenger's side front
airbag is disabled unless the PASSENGER AIRBAG OFFindicator lamp is lit. Make sure the child restraint is properly
installed (turn the vehicle off, remove the child restraint from
the vehicle and reinstall the restraint following the child
restraint manufacturer's instructions) and that the
PASSENGER AIRBAG OFF indicator lamp is on, or 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:
1. Turn the vehicle off and ask the person to
place the seat back 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.

01 Safety
Whiplash Protection System01

31 Whiplash Protection System (WHIPS) – front seats only
G020347
The Whiplash Protection System (WHIPS) con-
sists of specially designed hinges and brackets
on the front seat backrests designed to help
absorb some of the energy generated in a col-
lision 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 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 vehicle. 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.

meter. Press the button for more than
2 seconds to reset. Change between tripodometers 1 and 2 using one short press
on the button. – The display presents infor-
mation and warning messages, the ambi-
ent temperature, and the clock, etc. When
the ambient temperature is between 23°
and 36 °F (–5° and +2 °C), a snowflake
symbol is shown in the display. This sym-
bol serves as a warning for possible slip-
pery 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 tem-
perature.

Seat belt reminderThis symbol lights up to indicate
that the driver has not fastened his/
her seat belt.
Supplemental Restraint System (SRS)If this light comes on while the
vehicle is being driven, or remains
on for longer than approximately
10 seconds after the vehicle has
been started, the SRS system's
diagnostic functions have detected a fault in a
seat belt lock or pretensioner, 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.
BRAKE – Brake failure warning lightIf the light comes on while driving or braking,
stop immediately, open the hood and check
the brake fluid level in the reservoir. see
page 212.
Canadian models are equipped
with this warning light.
If the BRAKE and ABS warning lights come
on at the same time, this could indicate a
fault in the brake system.
•Stop the vehicle in a suitable place and
switch off the engine.
•Restart the engine.
•If both warning lights go off, no further
action is required.
•If both lights are still on after the engine has
been restarted, switch off the engine again
and check the brake fluid level (see
page 212 for the location of the brake fluid
reservoir).
If the brake fluid level is above the MIN mark,
drive carefully to a trained and qualified Volvo
service technician and have the brake system
inspected.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a Brake failure – Service
urgent message is displayed in the text
window: DO NOT DRIVE. Have the vehicle
towed to a trained and qualified Volvo serv-
ice technician and have the brake system
inspected.
PARK BRAKE Parking brake appliedThis light will be on when the parking brake
(hand brake) is applied. The parking brake
pedal is located on the left side of the driver's
footwell, see page 75 for more information.
Canadian models are equipped
with this symbol.
Oil pressure warning light2
If the light comes on while driv-
ing, stop the vehicle and then
stop the engine immediately and
check the engine oil level, see
page 58. If the light stays on after
restart, have the vehicle towed to the nearest
trained and qualified Volvo service technician.
After hard driving, the light may come on occa-
sionally when the engine is idling. This is nor-
mal, provided it goes off when the engine
speed is increased.
Generator warning lightIf the light comes on while the
engine is running, have the charg-
ing system checked.
2On certain engines, the symbol for low oilpressure is not used. Instead, a text warningis provided in the information display, see page 58.

CHECK ENGINE Malfunction indicator
light
On-Board Diagnostics II (OBDII): As you drive,
a computer called "OBDII" monitors your vehi-
cle's engine, transmission, electrical and emis-
sion 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 cau-
ses. Sometimes, you may not notice a change
in your vehicle's behavior. Even so, an uncor-
rected condition could hurt fuel economy,
emission cleanliness, and driveability.
Extended driving without correcting the cause
could even damage other components in your
vehicle.
Canadian models are equipped
with this warning light.
ABS (Anti-lock brake system)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 145 for additional information.
DSTC systemThe Dynamic Stability and Traction
Control system (DSTC) is
explained in greater detail on page
147.
Tire pressure monitoring lightSee page 189 for more informa-
tion on this 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 vehicle's turn signals are functioning.
