City Safety™

168
Limitations
The sensor used by City Safety™ is designed
to detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and dark-
ness.
However, there are certain limitations and the
laser sensor’s function may be reduced by, for
example, heavy rain or snowfall, or by dense
fog or thick, blowing dust or snow. Condensa-
tion, dirt, ice or snow on the windshield may
also interfere with the sensor’s function.
Objects such as warning flags hanging from
long objects on the roof or accessories such as
auxiliary lights or protective arches on the front
of the vehicle that are higher than the hood may
also impede the sensor’s function.
Braking distance to the vehicle ahead increa-
ses on slippery road surfaces, which may
reduce City Safety’s capacity to avoid a colli-
sion. In situations like this, the DSTC system
(see page 148) will help provide the best pos-
sible braking capacity and stability.
City Safety™ emits infrared light and measures
the way in which the light is reflected. There-
fore, vehicles or objects with low-reflective sur-
faces may not be detected. Normally, the
license plate and taillight reflectors give the
rear section of a vehicle ahead sufficient reflec-
tive surfaces to be detected.NOTE
•Keep the windshield in front of the laser
sensor free of ice, snow, dirt, etc. See
page 167.
•Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sen-
sor. Keep the hood free of ice and snow.
•Do not mount or in any way attach any-
thing on the windshield that could
obstruct the laser sensor.
Troubleshooting
If Windscreen Sensors blocked appears in
the information display, this indicates that the
City Safety™ laser sensor is obstructed in
some way and cannot detect vehicles ahead of
you, which means that the system is not func-
tioning.
However, this message will not be displayed in
all situations in which the sensor is obstructed.
For this reason, the driver must ensure that the
area of the windshield in front of the sensor is
always kept clean.
The following table shows some of the situa-
tions that can cause the message to be dis-
played and suggested actions.
CauseAction
The area of the
windshield in front of
the sensor is dirty or
covered by ice or
snow.Clean the wind-
shield or remove the
ice/snow.
The laser sensor's
field of view is
obstructed.Remove the
obstruction.
CAUTION
If a crack, scratch or stone chip should
occur in the section of the windshield in
front the laser sensor and covers an area of
approximately 1/50 x 1/10 in. (0.5 x 3 mm)
or larger, contact a trained and qualified
Volvo service technician to repair or replace
the windshield (see the illustration showing
the location of the sensor on page 167).
Failing to do so may result in reduced City
Safety™ functionality.
To help prevent reduced functionality,
please also observe the following:
•If the windshield is replaced, use the
same type or a windshield approved by
Volvo.
•When replacing windshield wipers, use
the same type or ones approved by
Volvo.

Collision warning with Full Auto-brake and Pedestrian Detection*

* Option/accessory, for more information, see Introduction.175
The camera’s limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 179), and Lane Departure Warning (see
page 182).
NOTE
•To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.
•Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.
WARNING
•The camera has the same limitations as
the human eye. In other words, its
“vision is impaired” by adverse weather
conditions such as heavy snowfall,
dense fog, etc. These conditions may
reduce the function of systems that
depend on the camera or cause these
systems to temporarily stop function-
ing.
•Never place any objects, decals, etc.,
on the windshield in front of the camera.
This could reduce or block the camera’s
function, and could cause one or more
of the systems that utilize the camera to
stop functioning.
•Strong sunlight, reflections from the
road surface, ice or snow covering the
road, a dirty road surface, or unclear
lane marker lines may drastically reduce
the camera’s capacity to detect the side
of a lane, a pedestrian or another vehi-
cle.
Pedestrians
The system cannot identify all pedestrians
The Collision Warning system can only identify
and detect a pedestrian who is standing
upright. This person can be standing still, walk-
ing or running.
This means that the system has to be able to
identify a person's head, arms, shoulders, legs,
the upper and lower parts of the body and a
person's pattern of movement when walking or
running.
If parts of the body are not visible to the cam-
era, the system cannot detect the pedestrian.
The following conditions apply:
•In order to detect a pedestrian, the system
must have a full view of the person's entire

body and the person must be at least
32 in. (80 cm) tall.
•The system cannot detect a pedestrian
carrying a large object.
•The camera's capacity to see a pedestrian
at dawn or dusk is limited, much as it is for
the human eye.
•The camera's function is deactivated and
will not detect a pedestrian in darkness or
in tunnels, even if there is street lighting in
the area.
WARNING
•Collision Warning with Full Auto-brake
and Pedestrian Detection is designed to
be a supplementary driving aid. It is not,
however, intended to replace the driv-
er's attention and judgement. The driver
is always responsible for operating the
vehicle in a safe manner.
•The system cannot detect all pedes-
trians in all situations, such as in dark-
ness/at night and cannot detect parti-
ally hidden pedestrians, people who are
less than approx. 32 in. (80 cm) tall, or
people wearing clothing that obscures
the contours of their bodies.
Fault tracing and actions
If the message Windscreen Sensors
blocked is displayed, this means that the cam-
era is obscured and cannot detect pedestrians,
vehicles or road marker lines in front of the
vehicle.
This, in turn, means that Collision Warning with
Full Auto-brake and Pedestrian Detection,
Lane Departure Warning, and Driver Alert Con-
trol will not have full functionality.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.

Rear Park Assist Camera (PAC)*
04
190* Option/accessory, for more information, see Introduction.
Using PAC
Activation
PAC is activated when the gear selector is
moved to R if the system is selected in the MY
CAR menu system or by pressing the CAM
button in the center console. See page 131 for
a description of the menu system.
If the Volvo Navigation System (VNS) is in use,
PAC will automatically override the navigation
system to show the camera&#39;s image on the
screen instead of navigation information, for as
long as reverse gear is selected.
ZoomThe camera can be useful when attaching a
trailer. Press CAM to zoom in on the trailer
hitch (and press this button again to return to
the normal camera view).With the camera zoomed in on the trailer hitch,
a guiding line showing the hitch&#39;s path toward
the trailer will be projected. This feature can be
activated in the MY CAR menu, see
page 132. The guiding lines for the wheels (see
the following section &#34;Guiding lines&#34;) and for
the trailer hitch cannot be displayed at the
same time.
If the camera shows an enlarged (zoomed)
image, turn TUNE counterclockwise, or press
EXIT, CAM or OK to return to a normal view.
DeactivationMove the gear selector from R to another posi-
tion. There is a slight delay in the PAC system,
which means that the view from behind the
vehicle will remain on the screen for approxi-
mately 15 seconds after the gear selector has
been moved from the R position or until the
vehicle reaches a forward speed of 6 mph
(10 km/h). The screen will then revert to the
mode that it was in before R was selected and
will, for example, display navigation system
information.
NOTE
If any button on the center console control
panel is pressed, the camera image will dis-
appear from the display. Pressing CAM will
return the camera image to the display.
Guiding lines
The lines on the screen are projected as if they
were a path on the ground behind the vehicle
and are affected by the way in which the steer-
ing wheel is turned. This enables the driver to
see path the vehicle will take, even if he/she
turns the steering wheel while backing up.
NOTE
When backing up with a trailer, the guiding
lines show the path that the vehicle will
take, not the trailer.
