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.

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 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 AIR-BAG 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 AIR-
BAG OFF indicator lamp is on, it is possible that
the person isn't sitting properly in the seat. If
this happens:
•Turn the vehicle off and ask the person to
place the seatback in an upright position.
•Have the person sit upright in the seat,
centered on the seat cushion, with the per-
son's legs comfortably extended.
•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.
•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
example by altering or adapting the driver's or
front passenger's seat(s) and/or airbag sys-
tems, please contact Volvo at:

Brake system
The brake system is a hydraulic system con-
sisting of two separate brake circuits. If a prob-
lem should occur in one of these circuits, it is
still possible to stop the vehicle with the other
brake circuit.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.
A warning light in the instrument panel will light
up to warn the driver that a fault has occurred.
If this light comes on while driving or braking,
stop immediately and check the brake fluid
level in the reservoir.
NOTE
Press the brake pedal hard and maintain
pressure on the pedal – do not pump the
brakes.
WARNING
If the fluid level is below the MIN mark in the
reservoir or if a brake system message is
shown in the information display: DO NOT
DRIVE. Have the vehicle towed to a trained
and qualified Volvo service technician and
have the brake system inspected.
Brake pad inspectionOn vehicles equipped with a jack*, the condi-
tion of the brake pads can be checked by rais-
ing the vehicle (see page 298 for information
about using the jack and removing a wheel)
and performing a visual inspection of the brake
pads.
WARNING
•If the vehicle has been driven immedi-
ately prior to a brake pad inspection, the
wheel hub, brake components, etc., will
be very hot. Allow time for these com-
ponents to cool before carrying out the
inspection.
•Apply the parking brake and put the
gear selector in the Park (P) position.
•Block the wheels standing on the
ground, use rigid wooden blocks or
large stones.
WARNING
•Use the jack intended for the vehicle
when changing a tire. For any other job,
use stands to support the vehicle.
•The jack should be kept well-greased
and clean, and should not be damaged.
•Be sure the jack is on a firm, level, non-
slippery surface.
•No objects should be placed between
the base of jack and the ground, or
between the jack and the attachment
bar on the vehicle.
•The jack must correctly engage the jack
attachment.
•Never allow any part of your body to be
extended under a vehicle supported by
a jack.
Brake lightsThe brake lights come on automatically when
the brakes are applied.
Adaptive brake lightsThe adaptive brake lights activate in the event
of sudden braking or if the ABS system is acti-
vated. This function causes an additional tail-
light on each side of the vehicle to illuminate to
help alert vehicles traveling behind.
The adaptive brake lights activate if:

WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.
The radar sensor's capacity to detect vehicles
ahead is impeded:
•if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor
clean.
•if the speed of vehicles ahead is signifi-
cantly different from your own speed.
Situations where ACC may not function
optimally
WARNING
•The radar sensor has a limited field of
vision. In some situations it may detect
a vehicle later than expected or not
detect other vehicles at all.
•If ACC is not functioning properly,
cruise control will also be disabled.
Radar sensor's field of vision (shown in pink)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters the
lane between your vehicle and the target
vehicle.
Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.
