The laser sensor
The upper decal describes the laser beam's
classification and contains the following text:
Invisible Laser radiation – Do not view directly
with optical instruments (magnifiers) – Class
1M laser product.
The lower decal describes the laser beam's
physical data and contains the text:
IEC 60825-1:1993 + A2:2001. Complies with
FDA performance standards for laser prod-
ucts except for deviations pursuant to Laser
Notice No. 50, dated July 26th, 2001
The laser beam's physical data is listed in the
following table:
Maximum pulse energy
2.64 μJ
Maximum average output
45 mW
Pulse length
33 ns
Divergence (horizontal × verti-
cal)
28° × 12°
The function of aftermarket laser detectors
may be affected by City Safety's laser sen-
sor.
WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
WARNING
Eye injury may occur if any of the following
points are not followed:
•
It is essential that all pertinent instruc-
tions be followed when handling laser
instruments. Testing, repairing, remov-
ing, adjusting and/or replacing any
components in the laser sensor may
only be done by a trained and qualified
Volvo service technician.
•
Do not remove the laser sensor
(including removal of the lenses). A
laser sensor that has been removed
belongs to laser class 3B according to
standard IEC 60825-1. Devices in laser
class 3B present a risk of injury to the
eyes.
•
The laser sensor’s connector must be
disconnected before the sensor is
removed from the windshield.
•
The laser sensor must be mounted in
place on the windshield before con-
necting the sensor’s connector.
•
Do not view the laser sensor (which
emits spreading, invisible laser beams)
with optical instruments from a dis-
tance of less than 4 inches (100 mm).

Collision warning – introduction
Pedestrian and Cyclist Detection with Full
Auto Brake is designed to assist the driver if
there is a risk of a collision with a pedestrian,
a cyclist, a vehicle ahead that is at a standstill
or one that is moving in the same direction as
your vehicle.
This system consists of the following three
functions:
•
Collision Warning warns the driver of a
potential collision situation.
•
Brake Support helps the driver brake
efficiently in a critical situation.
•
Auto-brake brakes the vehicle automati-
cally if a collision with a pedestrian, a
cyclist or another vehicle cannot be avoi-
ded and the driver does not apply the
brakes in time or steer around the per-
son/vehicle. Auto-brake can help prevent
a collision or reduce the speed at which a
collision occurs.
Since Pedestrian and Cyclist Detection with
Full Auto Brake is activated in circumstances
where the driver should have begun braking
much sooner, the system will not be able to
assist the driver in all situations.
This system is designed to activate as late as
possible to help avoid unnecessary interven-
tion.
The system should not be used in such a way
that the driver changes his/her way of operat-
ing the vehicle. If the driver relies entirely on
the system, the chances of an accident even-
tually occurring increase considerably.
The Pedestrian and Cyclist Detection with Full
Auto Brake and City Safety™ systems sup-
plement each other. See City Safety – intro-
duction (p. 202) for detailed information about
City Safety™.
WARNING
No automatic system can be guaranteed
to function 100% correctly in all situations.
For that reason, never test the Auto-brake
system by driving toward a person or
object. This could result in serious injury or
death.

WARNING
•
Pedestrian and Cyclist Detection with
Full Auto Brake does not work in all
driving, traffic, weather and road con-
ditions. It does not react to vehicles
not traveling in the same direction as
your vehicle.
•
Pedestrian and Cyclist Detection with
Full Auto Brake does not react to ani-
mals.
•
Warnings are only provided when the
risk of collision is high. The "Function"
section provides information about
limitations that the driver must be
aware of before using Collision Warn-
ing.
•
Pedestrian and Cyclist Detection with
Full Auto Brake will not provide a
warning or brake the vehicle for
pedestrians or cyclists at speeds
above 50 mph (80 km/h).
WARNING
•
Pedestrian and Cyclist Detection with
Full Auto Brake will not provide a
warning or brake the vehicle for
pedestrians in darkness or in tunnels,
even if there is street lighting in the
area.
•
The auto-brake function can help pre-
vent a collision or reduce the speed at
impact but the driver should always
apply the brakes for the best possible
braking effect, even if auto-brake is
actively applying the brakes.
•
Never wait for a collision warning. This
system is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's atten-
tion and judgement. The driver is
responsible for maintaining a safe dis-
tance and speed, even when the colli-
sion warning system is in use.
•
Maintenance of the Pedestrian and
Cyclist Detection with Full Auto Brake
system's components must only be
performed by a trained and qualified
Volvo technician.

Collision warning* – function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision Warning
The radar sensor and the camera work
together to detect a pedestrian, a cyclist, sta-
tionary vehicles and vehicles that are moving
in the same direction as your vehicle. If there
is a risk of collision with a vehicle, a cyclist or
a pedestrian, the driver is alerted by a flash-
ing red warning light and an audible warning
signal. The system is active at speeds above
3 mph (4 km/h).
Brake Support
If the risk of collision continues to increase
after the collision warning has been given,
Brake Support is activated. Brake Support
prepares the brake system to react quickly,
and the brakes are applied slightly. This may
be experienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided. Brake Support also
increases brake force if the system deter-
mines that the driver has not applied ade-
quate pressure on the brake pedal.
Auto-brake
If a collision is imminent and the driver has
not applied the brakes or begun to steer
around the vehicle, pedestrian or a cyclist,
the auto-brake function is activated without
the driver pressing the brake pedal. Full brake
force is applied to help reduce the vehicle’s
speed when the collision occurs or limited
brake force is applied if this is sufficient to
avoid the collision.
The auto-brake and brake support func-
tions are always on and cannot be turned
off.

not reduce the driver’s reaction time.
•
For the system to be as effective as
possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see Dis-
tance Alert – operation (p. 198).
•
When Adaptive Cruise Control is used,
the warning light and signal will be
used by that function, even if the
warnings provided by Pedestrian and
Cyclist Detection with Full Auto Brake
have been deactivated by the driver.

Collision warning* – Cyclist detection
The system can detect a cyclist and auto-
brake if certain parameters are fulfilled.
Optimal example of what the system considers
to be a cyclist: clear body/bike contours, straight
from behind and directly in front of the vehicle
In order to help detect a cyclist, the system
has to receive clear information about the
contours of the cyclist's body and the bike. It
has to able to clearly detect the bike, the
cyclist's head, arms, shoulders, legs and
upper and lower body combined with the per-
son's pattern of movement when cycling.
The function only detects cyclists from behind
who are moving in the same direction as your
vehicle
The Cyclist Detection feature requires the fol-
lowing in order to function:
•
The cyclist must be an adult riding an
"adult-size" bike
•
The bike must be equipped with an
approved and clearly visible rear-facing
red reflector that is mounted at least
27 in. (70 cm) above the road surface
•
The feature can only detect a cyclist
straight from behind and who is moving in
the same direction as your vehicle
•
A cyclist who is to the left or right of your
vehicle may be detected late or not at all.
•
The camera's capacity to see a cyclist 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 cyclist in darkness or in

tunnels, even if there is street lighting in
the area.
•
For optimal cyclist detection, City
Safety™ must be activated.
WARNING
Pedestrian and Cyclist Detection with Full
Auto Brake is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's attention
and judgement. The driver is always
responsible for operating the vehicle in a
safe manner.
The system cannot detect a bike/cyclist if:
•
He/she is wearing loose-fitting clothing
that may obscure body contours
•
The bike is approaching your vehicle
from the side
•
The bike is not equipped with a rear-
facing red reflector
•
The bike is carrying large objects
•
Most of the cyclist's body or the bike
itself cannot be "seen" by the system's
camera

detection
The system cannot identify all pedestrians
The Pedestrian and Cyclist Detection with Full
Auto Brake system can only identify and
detect a pedestrian who is standing upright.
This person can be standing still, walking 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 sys-
tem 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 pedes-
trian 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.

however, intended to replace the driv-
er's attention and judgement. The
driver is always responsible for operat-
ing 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.

Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may make
the visual warning signal in the windshield dif-
ficult to see. For this reason, always activate
the audible warning signal.
Slippery driving conditions increase braking
distance, which can reduce the system's
capacity to avoid a collision. In these condi-
tions, the ABS and stability systems provide
the best possible braking effect while helping
to maintain stability.
The visual warning signal may be tempo-
rarily disengaged in the event of high pas-
senger compartment temperature due to
strong sunlight, etc. If this occurs, the
audible warning signal will be used, even if
it has been deactivated in the menu sys-
tem.

WARNING
•
In certain situations, the system can-
not provide warnings or warnings may
be delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian, a cyclist or a vehicle
ahead.
•
Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
•
The sensor system has a limited range
for pedestrians/cyclists and provides
warnings and braking effect most
effectively at speeds up to 30 mph
(50 km/h). For stationary or slow-mov-
ing vehicles, the system functions best
if your vehicle’s speed is below
approximately 45 mph (70 km/h).
•
Warnings for stationary or slow-mov-
ing vehicles may not be provided in
dark conditions or in poor visibility.
The Pedestrian and Cyclist Detection with Full
Auto Brake system uses the same radar sen-
sors as Adaptive Cruise Control. For more
information on the radar sensor and its limita-
tions, see Adaptive Cruise Control – limita-
If warnings are given too frequently, the
warning distance can be reduced (see Col-
lision warning* – operation (p. 212)). This
causes the system to provide later warn-
ings, which decreases the total number of
warnings provided.
WARNING
•
The system is not activated at speeds
under approx. 2 mph (4 km/h). There-
fore, it will not brake your vehicle if you
approach a vehicle ahead at very low
speed, such as when parking.
•
The driver's actions always have high-
est priority and override the Pedestrian
and Cyclist Detection with Full Auto
Brake system. This means that the
system will not intervene in situations
where the driver is actively steering,
braking or pressing the accelerator
pedal, even if a collision is imminent.
•
When Auto-brake has prevented a col-
lision with a stationary object, your
vehicle will remain at a standstill for
approx. 1.5 seconds. If your vehicle
has been braked for a moving vehicle
ahead, your vehicle's speed will be
reduced to the same speed as that
vehicle's.

The camera’s limitations
The camera has the same limitations as the
human eye.
The camera is used by Pedestrian and Cyclist
Detection with Full Auto Brake Collision warn-
ing – introduction (p. 209), Active High Beams
(Active high beams (AHB)* (p. 90)), Road Sign
Information (Road Sign Information (RSI)* –
introduction (p. 179)) and Driver Alert System
(Driver Alert System (p. 222)) with Lane
Departure Warning.
•
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 type of limi-
tations as the human eye, i.e., it can-
not see as well in heavy snowfall or
rain, thick fog or in heavy blowing dust
or snow. In such conditions, systems
depending on the camera may experi-
ence greatly reduced functionality or
may be temporarily deactivated.
•
Never place any objects, decals, etc.,
on the windshield in front of the cam-
era. 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,
a cyclist or another vehicle.
