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 in the event
of a collision 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.

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 passeng-
er'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 exer-
ted 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 passen-
ger should always be on the seat cush-
ion. 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 Automatic Locking
Retractor/Emergency Locking Retrac-
tor (ALR/ELR) seat belt (see page 38).
•No objects should be placed under the
front passenger's seat. This could inter-
fere with the OWS system's function.

Positioning the seat belt through the infant seat
WARNING
•An infant seat must be in the rear-facing
position only.
•The infant seat should not be positioned
behind the driver's seat unless there is
adequate space for safe installation.
1. Place the infant seat in the rear seat of the
vehicle.
2. Attach the seat belt to the infant seat
according to the manufacturer's instruc-
tions.
G026492
Fasten the seat belt
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 posi-
tion.

NOTE
When driving in daylight conditions, the
headlights will switch off and the daytime
running lights will come on. In darkness, the
daytime running lights will switch off and the
Active Bending Lights will switch on.
The ABL function is activated automatically
when the engine is started and the headlight
switch is in the
position and can be
deactivated/reactivated by pressing the button
in the center console (see page 64.
LED Daytime Running Lights (DRL)
To help conserve fuel by reducing the use of
electrical current in the vehicle, DRL can be
used in daylight conditions instead of the low
beam headlights, which consume more elec-
trical current. The daytime running lights are
mounted in the front spoiler and use bright,
electricity-saving LEDs (light emitting diodes).
Press button A to activate automatic DRL in day-
light driving conditions
With the headlight switch in the position
as shown in the illustration, press the button
with the A symbol to activate the automatic
LED daytime running lights in daylight driving
conditions (the indicator light in the button will
illuminate). A light sensor then monitors the
ambient lighting conditions and automatically
switches from LED DRL to the low beam head-
lights in weaker ambient light (and will switch
back to DRL when the ambient light becomes
brighter). Press the button again (the indicator
light in the switch will turn off) to switch on the
headlights.The LED DRLs will also switch off automatically
(and the low beams will switch on) if:
•The rear fog light is switched on
•The windshield wipers are switched on for
more than 10 seconds
If the LED DRL function was activated when the
ignition was switched off, it will be active when
the ignition is switched on again.
WARNING
•DRL is a driving aid designed to help
conserve electrical current. This system
cannot always determine if the ambient
lighting conditions are sufficient for
switching from low beams to DRL (or
vice versa). It is always the driver's
responsibility to visually determine if the
low beam headlights should be used.
•As the driver, you have full responsibility
for operating the vehicle in a safe man-
ner.

Windshield wipers offIf the lever is in the 0 position and
you move it upwards, the wipers
will sweep one stroke at a time for
as long as you hold the lever up.
Single sweep positionMove the lever slightly upward
from the 0 position for one sweep
of the wipers. The lever returns
automatically to 0 when released.
Intermittent wiper functionWith the lever in this position, you
can set the wiper interval by twist-
ing the control ring (1) upward to
increase wiper speed or down-
ward to decrease the speed.
Windshield washer/headlight washer
(certain models)
When the lever is pulled to wash the wind-
shield, high pressure jets mounted in the
bumper will spray the headlights.
CAUTION
•Use ample washer fluid when washing
the windshield to avoid scratching the
glass. The windshield should be thor-
oughly wet when the wipers are in oper-
ation.
•Before using the wipers, ice and snow
should be removed from the wind-
shield/rear window. Be sure the wiper
blades are not frozen in place.
•To conserve washer fluid in driving condi-
tions where the windshield washers are
used frequently, the headlights will only be
washed once for every five times the wind-
shield is washed within a 10-minute period.
•A short pull on the lever will wash the wind-
shield only.
•When approximately 1 US quart (1 liter)
remains in the washer fluid reservoir, the
headlights will not be washed when the
lever is pulled to conserve washer fluid for
the windshield. A text message will also be
displayed to remind the driver to fill the
washer fluid reservoir.

Rain sensor*
The rain sensor automatically regulates wiper
speed according to the amount of water on the
windshield.
The sensitivity of the sensor can be adjusted
by twisting ring (1) up (the wipers will sweep the
windshield more frequently) or down (the wip-
ers will sweep the windshield less frequently).
Activating the rain sensor:1.
Turn the ignition key to at least position I
and put the windshield wiper lever in posi-
tion 0.
2. Press button (2), see page 72.
> A light in the button will light up to indi-
cate that the rain sensor is active.
Deactivating the rain sensor:
•Press button (2), see page 72.
or
•Move the windshield wiper lever down to
another position. Moving the lever up will
not deactivate the rain sensor. Doing so
will cause the wipers to sweep the wind-
shield until the lever is released, at which
time the wipers return to rain sensor mode.
The rain sensor is also deactivated when the
key is removed from the ignition.
CAUTION
The rain sensor should be deactivated when
washing the vehicle in an automatic car
wash, etc. If the rain sensor function is left
on, the wipers will start inadvertently in the
car wash and could be damaged.

Condensation on the inside of the
windows
Keeping the insides of the windows clean will
help reduce the amount of condensation that
forms on the windows. Use a commercial win-
dow cleaning agent to clean the windows.
Ice and snow
Always keep the air intake grille at the base of
the windshield free of snow.
Cabin air filter
Replace the cabin air filter with a new one at
the recommended intervals. Please refer to
your Warranty and Service Records Informa-
tion booklet, or consult a trained and qualified
Volvo service technician for these intervals.
The filter should be replaced more often when
driving under dirty and dusty conditions. The
filter cannot be cleaned and therefore should
always be replaced with a new one.
Sensors
The sunlight sensor on the dashboard and pas-
senger compartment temperature sensor in
the ECC control panel should not be covered
in any way as this could cause incorrect infor-
mation to be sent to the ECC system.
Parking the vehicle in warm weather
If your vehicle has been parked in the sun in
warm weather, opening the windows and
moonroof* for several minutes before driving
will help release the warm air from the passen-
ger compartment. When the engine is running,
close the windows and moonroof and use the
recirculation function for several minutes to
enable the air conditioning to cool the com-
partment as quickly as possible.
Windows and optional moonroof
The ECC system will function best if the win-
dows and optional moonroof are closed. If you
drive with the moonroof open, we recommend
that you manually adjust the temperature and
blower control (the LED in the AUTO switch
should be off).
Acceleration
The air conditioning is momentarily disen-
gaged during full-throttle acceleration.
Climate control maintenance
Special tools and equipment are required to
maintain and carry out repairs on the climate
system. Work of this type should only be done
by a trained and qualified Volvo service tech-
nician.
Refrigerant
Volvo cares about the environment. The air
conditioning system in your vehicle contains a
CFC-free refrigerant – R134a (HFC134a). This
substance will not deplete the ozone layer. The
approximate amount of R134a contained in the
system is a follows:
6-cylinder engine
Single A/C system: 1.5 lbs (700 g)
Dual
1 A/C system: 2.2 lbs (1000 g)
The system also uses PAG oil.

Interior air quality sensor*
Some vehicles are equipped with a multifilter
and air quality sensor. The filter separates
gases and particles, thereby reducing the
amounts of odors and contaminants entering
the vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-
