194* Option/accessory, for more information, see Introduction.
Activating/deactivating warning signalsThe warning lamp is activated automatically
when the engine is started if the system is
switched on.
The warning sound can be activated/deacti-
vated separately using the options for
On orOff in the menu system MY CAR under
Settings
Car settingsDriving support
systems
Warning sound if risk of
collision.
Set warning distanceThe warning distance regulates the distance at
which the visual and acoustic warnings are
deployed. Select one of the options from
Long, Normal or Short in the menu system
MY CAR under Settings
Car settings
Driving support systemsCollision
Warning
Warning distance.
The warning distance determines the system's
sensitivity. Warning distance
Long provides an
earlier warning. First test with Long and if this
setting produces too many warnings, which
could be perceived as irritating in certain sit-
uations, then change to warning distance
Normal.
Only use warning distance
Short in excep-
tional cases, e.g. for dynamic driving.
NOTE
When the adaptive cruise control is in use
the warning lamp and warning sound will be
used by the cruise control even if the colli-
sion warning system is switched off.
The collision warning system warns the
driver in the event of a risk of a collision, but
the function cannot shorten driver reaction
time.
In order for the collision warning system to
be effective, always drive with the Distance
Alert set at time interval 4 – 5. see
page 185.
NOTE
Even if the warning distance has been set toLong warnings could be perceived as being
late in certain situations, e.g. when there are
large differences in speed or if vehicles in
front brake heavily.
Checking settingsThe settings required can be controlled on the
centre console display screen. Search with the
menu system MY CAR under Settings
Car
settings
Driving support systems
Collision Warning, see page 144.
Limitations
The collision warning system is active from and
including approx. 4 km/h.
The visual warning signal may be difficult to
notice in the event of strong sunlight, reflec-
tions, when sunglasses are being worn or if the
driver is not looking straight ahead. The warn-
ing sound should therefore always be acti-
vated.
On slippery road surfaces the braking distance
is extended, which may reduce the capacity to
avoid a collision. In such situations the ABS
and DSTC systems will provide best possible
braking force with maintained stability.
NOTE
The visual warning signal can be temporarily
disengaged in the event of high passenger
compartment temperature caused by
strong sunlight for example. If this occurs
then the warning sound is activated even if
it is deactivated in the menu system.
•Warnings may not appear if the dis-
tance to the vehicle in front is small or if
steering wheel and pedal movements
are large, e.g. a very active driving style.

WARNING
Warnings and brake interventions could be
implemented late or not at all if the traffic
situation or external influences mean that
the radar or camera sensor cannot detect a
pedestrian or a vehicle in front correctly.
The sensor system has a limited range for
pedestrians and the system therefore pro-
vides effective warnings and brake inter-
ventions at vehicle speeds up to 50 km/h.
For stationary or slow-moving vehicles,
warnings and brake interventions are effec-
tive at vehicle speeds up to 70 km/h.
Warnings for stationary or slow-moving
vehicles could be disengaged due to dark-
ness or poor visibility.
The collision warning system uses the same
radar sensors as adaptive cruise control. For
more information on the radar sensor and its
limitations, see page 181.
If warnings are perceived as being too frequent
or disturbing then the warning distance can be
reduced. This would lead to the system warn-
ing at a later stage, which reduces the total
number of warnings.
When the car is reversing Collision Warning
with Auto Brake cannot be activated.
Collision Warning with Auto Brake is not acti-
vated at low speeds - under 4 km/h, which iswhy the system does not intervene in situations
where the car is approaching a vehicle in front
very slowly, e.g. when parking.
Driver commands are always prioritised, which
is why Collision Warning with Auto Brake does
not intervene in situations where the driver is
steering, braking or accelerating in a clear
manner, even if a collision is unavoidable.
When Auto Brake has prevented a collision
with a stationary object the car remains sta-
tionary for a maximum of 1.5 seconds. If the car
is braked for a vehicle in front that is moving,
then speed is reduced to the same speed as
that maintained by the vehicle in front.
On a car with manual gearbox the engine stops
when Auto Brake has stopped the car, unless
the driver manages to depress the clutch pedal
beforehand.
Camera sensor limitationsThe car's camera sensor is used by the three
functions - Collision Warning with Auto Brake,
Driver Alert Control, see page 199 and Lane
Departure Warning, see page 202.
NOTE
Keep the windscreen surface in front of the
camera sensor clean from ice, snow, mist
and dirt.
Do not attach or fit anything to the wind-
screen in front of the camera sensor, as this
could reduce or prevent the function of one
or more camera-dependent systems.
The camera sensors have limitations similar to
the human eye, i.e. they "see" worse in dark-
ness, heavy snowfall or rain and in thick fog for
example. Under such conditions the functions
of camera-dependent systems could be sig-
nificantly reduced or temporarily disengaged.
Strong oncoming light, reflections in the car-
riageway, snow or ice on the road surface, dirty
road surfaces or unclear lane markings could
also significantly reduce camera sensor func-
tion when it is used to scan the carriageway
and detect pedestrians and other vehicles.
During very high temperatures the camera is
temporarily switched off for about 15 minutes
after the engine is started in order to protect
camera functionality.

Detection of pedestrians
Optimal examples of what the system regards as
pedestrians with clear body contours.
Optimal performance of the system requires
that the system function that detects pedes-
trians receives as unambiguous information as
possible about the contours of the body - this
implies the opportunity to identify the head,
arms, shoulders, legs, upper and lower body
combined with a normal human pattern of
movement.
If large parts of the body are not visible to the
camera then the system cannot detect a
pedestrian.
•In order for a pedestrian to be detected he/
she must appear full-length and have a
height of at least 80 cm.
•The system cannot detect a pedestrian
carrying larger items.
•The camera sensor's ability to see pedes-
trians at dusk and dawn is limited - just like
the human eye.
•The camera sensor's capacity to detect
pedestrians is deactivated when driving in
darkness and tunnels - even when street-
lights are lit.
WARNING
Collision Warning with Auto Brake & Pedes-
trian Detection is a means of assistance.
It cannot detect all pedestrians in all situa-
tions and it cannot see e.g. partially
obscured pedestrians, people in clothing
that hides the contours of the body or
pedestrians shorter than 80 cm.
•The driver is always responsible that the
vehicle is driven properly and with a
safety distance adapted to the speed.
Fault tracing and action
If the display shows the message Windscreen
Sensors blocked then this means that the
camera sensor is blocked and cannot detect
pedestrians, vehicles or road markings in front
of the car.In turn this means that the Collision Warning
with Auto Brake, Lane Departure Warning and
Driver Alert Control functions are not operating
with full functionality.
The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The windscreen sur-
face in front of the
camera is dirty or
covered with ice or
snow.Clean the wind-
screen surface in
front of the camera
from dirt, ice and
snow.
Thick fog, heavy rain
or snow means that
the camera does not
work sufficiently
well.No action. At times
the camera does not
work during heavy
rain or snowfall.

Driver Alert System - LDW*
04
202* Option/accessory, for more information, see Introduction.
General information on Lane Departure
Warning - LDW
The function is intended to reduce the risk for
single-vehicle accidents – accidents where, in
certain situations, the vehicle leaves the car-
riageway and is in danger of driving either into
a ditch or into oncoming traffic.
LDW consists of a camera that detects the side
markings painted on the carriageway. The
driver is alerted by an acoustic signal if the
vehicle crosses a side marking.
Operation and function
The function is switched on or off by means of
a switch on the centre console. An indicator
lamp in the button illuminates when the func-
tion is switched on.
The trip computer display shows
Lane Depart
Warn Standby <65 km/h when the function is
in standby mode due to speed being below 65
km/h.
The LDW function is activated automatically
from standby mode after the camera has scan-
ned in the carriageway's side markings and
speed exceeds 65 km/h. The trip computer
display then shows
Lane Depart Warn
Available.If the camera can no longer detect the carria-
geway's side markings the display shows
Lane Depart Warn Unavailable.
If speed decreases to below 60 km/h then the
function resumes standby mode and the dis-
play shows
Lane Depart Warn Standby <65
km/h.
If the vehicle crosses the left or right-hand side
marking of the carriageway without due cause
then the driver is alerted by an acoustic signal.
No warning is given in the following situations:
•Direction indicators activated
•The driver has his/her foot on the brake
pedal1
•In the event of the accelerator pedal being
depressed rapidly1
•In the event of rapid steering wheel move-
ments1
•In the event of a sudden turn so that the car
rolls.
The camera sensor also has certain limitations.
For more information, see page 195.
1A warning is still given when Increased sensitivity is selected, see page 204.

behind and in front of the car, then the tone
sounds alternately from the loudspeakers.
IMPORTANT
Certain objects e.g. chains, thin glossy
poles or low barriers may be in the "signal
shadow" and are then temporarily not
detected by the sensors - the pulsating tone
may then unexpectedly stop instead of
changing over to the expected constant
tone.
•In which case, pay extra attention and
manoeuvre/reposition the car particu-
larly slowly or stop the current parking
manoeuvre - there may be a high risk of
damage to vehicles or other objects
since the sensors are unable to function
optimally.
Rear parking assistance
The distance covered to the rear of the car is
about 1.5 metres. The acoustic signal for
obstacles behind comes from one of the rear
loudspeakers.
Rear parking assistance is activated when
reverse gear is engaged.
The system must be deactivated when revers-
ing with a trailer or bike carrier on the towbar
or similar - otherwise they would trigger the
sensors.
NOTE
Rear parking assistance is deactivated
automatically when towing a trailer if Volvo
genuine trailer wiring is used.
Front parking assistance
The distance covered in front of the car is about
0.8 metres. The acoustic signal for obstacles in
front comes from one of the front loudspeak-
ers.
Front parking assistance is active up to
15 km/h. The lamp in the button is illuminated
in order to indicate that the system is activated.
When the speed is below 10 km/h the system
is reactivated.
NOTE
Front parking assistance is deactivated
when the parking brake is applied or P mode
is selected in a car with an automatic gear-
box.

IMPORTANT
When fitting auxiliary lamps: Remember that
they must not obscure the sensors – the
auxiliary lamps could then be detected as
obstacles.
Fault indicator
If the information symbol illuminates
with constant glow and the informa-
tion display shows
Park assist syst Service
required then parking assistance is disen-
gaged.
IMPORTANT
In certain conditions the parking assistance
system may produce incorrect warning sig-
nals that are caused by external audio
sources that emit the same ultrasonic fre-
quencies that the system works with.
Examples of such sources include horns,
wet tyres on asphalt, pneumatic brakes and
exhaust noises from motorcycles etc.
Cleaning the sensors
Sensor location, front.
Sensor location, rear.
The sensors must be cleaned regularly to
ensure that they work properly. Clean them
with water and car shampoo.
NOTE
Dirt, ice and snow covering the sensors may
cause incorrect warning signals.
