City Safety™
04
186
When City Safety™ 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 City Safety™ has stopped the car, unless
the driver manages to depress the clutch pedal
beforehand.
NOTE
•Keep the windscreen surface in front of
the laser sensor free from ice, snow and
dirt (see the illustration for sensor loca-
tion, page 184).
•Do not affix or mount anything on the
windscreen in front of the laser sensor
•Remove ice and snow from the bonnet
- snow and ice must not exceed a height
of 5 cm.
Fault tracing and action
If the message Windscreen Sensors
blocked is shown on the instrument panel dis-
play, it indicates that the laser sensor is
blocked and cannot detect vehicles in front of
the car. This means that City Safety™ is not
operational.The
Windscreen Sensors blocked message
is not shown for all situations in which the laser
sensor is blocked. The driver must therefore be
diligent about keeping the windscreen and
area in front of the laser sensor clean.
The following table presents possible causes
for the message being shown, along with sug-
gestions for appropriate action.
CauseAction
The windscreen sur-
face in front of the
laser sensor is dirty
or covered with ice
or snow.Clean the wind-
screen surface in
front of the sensor
from dirt, ice and
snow.
The laser sensor
field of vision is
blocked.Remove the block-
ing object.
IMPORTANT
If there are cracks, scratches or stone chips
in the windscreen in front of either of the
laser sensor's "windows" and they cover a
surface of approx. 0.5 x 3.0 mm (or larger),
then a workshop must be contacted for
repair or replacement of the windscreen
(see the illustration for sensor location, page
184) - an authorised Volvo workshop is rec-
ommended.
Failure to take action may result in reduced
performance for City Safety™.
To avoid the risk of reducing City Safety™
performance the following also applies:
•The same type or a Volvo-approved
windscreen must be fitted during
replacement
•The same type or Volvo-approved
windscreen wipers must be fitted during
replacement.
Laser sensor
The City Safety™ function includes a sensor
which transmits laser light. Contact a qualified
workshop in the event of a fault or if the laser
sensor needs servicing - an authorised Volvo
workshop is recommended.

WARNING
Never look into the laser sensor (which
emits spreading invisible laser radiation) at
a distance of 100 mm or closer with magni-
fying optics such as a magnifying glass,
microscope, lens or similar optical instru-
ments - this would involve a risk of eye injury
(the illustration on page 184 shows sensor
location).
For more information on the laser sensor, see
page 10.

Collision Warning & Pedestrian Detection with Auto Brake*

* Option/accessory, for more information, see Introduction.189 Function
Functions overview.
Visual warning signal in the event of a col-
lision risk
Radar sensor
Camera sensor
Collision warningTogether with a camera sensor, the radar sen-
sor detects pedestrians, stationary vehicles as
well as vehicles driving in the same direction in
front of the car.
In the event of there being a risk of collision with
a pedestrian or such a vehicle your attention is
drawn with a red flashing warning signal and a
warning sound.
Brake supportIf the risk of collision still increases after the
collision warning then the brake support is acti-
vated. The brake support prepares the brake
system for rapid braking and the brakes are
applied gently, which may be noticed as a
slight jerk.
If the brake pedal is depressed sufficiently
quickly then full brake function is implemented.
Brake support also reinforces the driver's brak-
ing if the system considers that the braking is
not sufficient to avoid a collision.
Auto BrakeIf the driver has not yet started an evasive
manoeuvre in this situation and the risk of a
collision is imminent then the Auto Brake func-
tion comes into effect, without the driver need-
ing to touch the brake pedal. Braking then
takes place with full brake force in order to
reduce collision speed, or with limited brake
force if it is sufficient to avoid collision.
Operation
Settings are made from MY CAR via the centre
console display screen and menu system. For
information on how the menu system is used,
see page 142.
NOTE
The Brake Support and Auto Brake func-
tions are always enabled - they cannot be
deactivated.
On and OffTo select whether the collision warning system
should be switched on or off: Search with the
menu system MY CAR via the centre console
display screen and locate Settings

Collision Warning. For information on the
menu system,see page 142.
An activated function is tested at each engine
start by briefly illuminating the warning lamp's
separate points of light.
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.

Driver 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 181.
NOTE
Even if the warning distance has been set toLong then in certain situations warnings
could be perceived as being late. E.g. in the
event of large differences in speed or if vehi-
cles 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
Driver support systems
Collision Warning, see page 142.
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 177.
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 195 and Lane
Departure Warning, see page 198.
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.

192* Option/accessory, for more information, see Introduction.
Detection of pedestrians (Pedestrian
detection)
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 is an
assistance tool.
It cannot detect all pedestrians in all situa-
tions and it cannot see e.g. partially
obscured pedestrians, shorter people or
children (below 80 cm) or people in clothing
that hides the contours of the body.
•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 detectpedestrians, 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.

The function is activated when speed
exceeds 65 km/h and remains active
as long as the speed is over
60 km/h.
The display shows a level mark with 1-5 bars,
where a low number of bars indicates incon-
sistent driving style. A high number of bars
indicates stable driving.
If the vehicle is driven inconsistently then the
driver is alerted by an acoustic signal as well as
the text message
Driver Alert Time for a
break. The warning is repeated after a time if
driving ability does not improve.
WARNING
An alarm should be taken very seriously, as
a sleepy driver is often not aware of his/her
own condition.
In the event of an alarm or a feeling of tired-
ness; stop the car in a safe manner as soon
as possible and rest.
Studies have shown that it is equally as dan-
gerous to drive while tired as it is under the
influence of alcohol.
