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:

force distribution system.
1. Stop the vehicle in a safe place and turn off
the engine.
2. Restart the engine.
•If both symbols extinguish, continue driv-
ing.
•If the symbols remain on, check the level in
the brake fluid reservoir, see page 258. If
the brake fluid level is normal but the sym-
bols are still lit, the vehicle can be driven,
with great care, to an authorized Volvo
workshop to have the brake system
checked.
•If the level in the reservoir is below MIN, the
vehicle should be transported to an author-
ized Volvo workshop to have the brake
system checked.

Brakes
03

115 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 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:
•The ABS system activates for more than
approximately a half second
•In the event of sudden braking while the
vehicle is moving at speeds above approx-
imately 6 mph (10 km/h)
When the vehicle has come to a stop, the brake
lights and additional taillights remain on for as
long as the brake pedal is depressed or until
braking force on the vehicle is reduced.
Power brakes function only when the
engine is running
The power brakes utilize vacuum pressure
which is only created when the engine is run-
ning. Never let the vehicle roll to a stop with the
engine switched off.
If the power brakes are not working, consider-
ably higher pressure will be required on the
brake pedal to compensate for the lack of
power assistance. This can happen for exam-ple when towing your vehicle or if the engine is
switched off when the vehicle is rolling. The
brake pedal feels harder than usual.
Water on brake discs and brake pads
affects braking
Driving in rain and slush or passing through an
automatic car wash can cause water to collect
on the brake discs and pads. This will cause a
delay in braking effect when the pedal is
depressed. To avoid such a delay when the
brakes are needed, depress the pedal occa-
sionally when driving through rain, slush, etc.
This will remove the water from the brakes.
Check that brake application feels normal. This
should also be done after washing or starting
in very damp or cold weather.
Severe strain on the brake systemThe brakes will be subject to severe strain
when driving in mountains or hilly areas, or
when towing a trailer. Vehicle speed is usually
slower, which means that the cooling of the
brakes is less efficient than when driving on
level roads. To reduce the strain on the brakes,
shift into a lower gear and let the engine help
with the braking. Do not forget that if you are
towing a trailer, the brakes will be subjected to
a greater than normal load.

Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.165
Standby mode due to action by the driverACC is temporarily deactivated and put in
standby mode:
•when the brakes are applied
•if the gear selector is moved to N
•if the accelerator pedal is depressed for
more than 1 minute.
NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic standby modeAdaptive cruise control is linked to other sys-
tems such as the stability and traction control
system (DSTC). If this system is not functioning
properly, adaptive cruise control is automati-
cally deactivated and will go into standby
mode.
In the event of automatic deactivation, an audi-
ble signal will sound and the message
Cruise
control Cancelled is shown in the display.
The driver must then intervene and adapt the
vehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.
An automatic switch to standby mode may be
caused if:
•the vehicle's speed falls below 20 mph
(30 km/h)
•the wheels lose traction
•brake temperature is high
•engine speed (rpm) is too low or too high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Turning ACC off completely
A short press on in standby mode or a long
press in active mode turns ACC off completely.
The set speed and time interval are then
cleared from the system's memory and cannot
be resumed by pressing
.
The radar sensor and its limitations
In addition to being used by ACC, the radar
sensor is also used by Distance Alert (see
page 170) and Collision Warning with Auto-
brake (see page 173). This sensor is designed
to detect cars or larger vehicles driving in the
same direction as your vehicle, in the same
lane.
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.

186* Option/accessory, for more information, see Introduction.
Front park assist
G021424
The distance monitored in front of the vehicle
is approximately 2.5 ft (0.8 m). The audible sig-
nal comes from the audio system's front
speakers.
It may not be possible to combine auxiliary
headlights and front park assist since these
lights could trigger the system's sensors.
NOTE
Front park assist is deactivated when the
parking brake is applied and or when the
gear selector is in the P position.
Faults in the system
If the information symbol illuminates and Park
assist syst Service required is shown on the
information display, this indicates that the sys-
tem is not functioning properly and has been
disengaged. Consult a trained and qualified
Volvo service technician.
CAUTION
In certain circumstances, the park assist
system may give unexpected warning sig-
nals that can be caused by external sound
sources that use the same ultrasound fre-
quencies as the system. This may include
such things as the horns of other vehicles,
wet tires on asphalt, pneumatic brakes,
motorcycle exhaust pipes, etc. This does
not indicate a fault in the system.

192* Option/accessory, for more information, see Introduction.
Introduction
G021426
BLIS camera
Indicator light
BLIS symbol
The Blind Spot Information System (BLIS) is an
information system that indicates the presence
of another vehicle moving in the same direction
as your vehicle in the side-view mirror's "blind
area."
CAUTION
The BLIS system should only be repaired by
a trained and qualified Volvo service tech-
nician.
WARNING
•BLIS is an information system, NOT a
warning or safety system.
•BLIS does not eliminate the need for
you to visually confirm the conditions
around you, and the need for you to turn
your head and shoulders to make sure
that you can safely change lanes.
•As the driver, you have full responsibility
for changing lanes in a safe manner.
The system is based on digital camera tech-
nology. The cameras are located beneath the
side-view mirrors.
When one (or both) of the cameras have
detected a vehicle in the blind area (up to
approximately 10 ft. (3 meters) from the side of
your vehicle, and up to approximately 31 ft.
(9.5 meters) behind the side-view mirror), see
the illustration, the indicator light in the door
panel illuminates. The light will glow continu-
ously to alert the driver of the vehicle in the
blind area.
NOTE
The door panel indicator light illuminates on
the side of the vehicle where the system has
detected another vehicle. If your vehicle is
passed on both sides at the same time, both
lights will illuminate.
BLIS has an integrated function that alerts the
driver if a fault should occur with the system.
For example, if one or both of the system's
cameras are obscured, a message (see the
table on page 194) will appear in the informa-
tion display in the instrument panel. If this
occurs, clean the camera lenses. If necessary,
the system can be temporarily switched off (for
instructions, see page 194).
Areas monitored by BLIS Distance A = approx.
31 ft. (9.5 meters), Distance B = approx. 10 ft.
(3 meters)
