155 Function
Location of the laser sensor in the windshield2
City Safety™ monitors traffic ahead of you
using a laser sensor mounted in the upper sec-
tion of the windshield. If a collision is imminent,
City Safety™ will automatically apply the
brakes, which may feel like hard braking.
If the difference in speed between your vehicle
and the vehicle ahead is more than approxi-
mately 9 mph (15 km/h), City Safety™ alone
cannot prevent a collision from taking place.
The driver must apply the brakes to help avoid
a collision or reduce its effect.
When the function activates and applies the
brakes, a message will appear in the informa-tion display to indicate that the system is/has
been active.
NOTE
•When City Safety™ applies the brakes,
the brake lights will illuminate.
•In cases where City Safety™ has stop-
ped the vehicle, the system will then
release the brakes. The driver must
apply the brakes to keep the vehicle at
a standstill.
Using City Safety™
NOTE
The City Safety™ function is activated auto-
matically each time the engine has been
switched off and restarted.
On and OffIn certain situations, it may be desirable to
switch City Safety™ off, such as when driving
in close quarters where leaves, branches, etc.
may obscure the hood and windshield.
When the engine is running, City Safety™ can
be switched off as follows:Press My Car in the center console control
panel and go to Settings
Car settings
Driver support systemsCity Safety.
Select
Off.
If the engine is switched off, City Safety™ will
reactivate when the engine is restarted.
WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
To switch City Safety™ on again:
•Follow the same procedure as for switch-
ing City Safety™ off but select On.
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.

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 (includ-
ing removal of the lenses). A laser sen-
sor 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 distance
of less than 4 inches (100 mm).
Symbols and messages in the display
When City Safety™ automatically applies the
brakes, one or more of the symbols in the main
instrument panel may illuminate and its asso-
ciated message will be displayed.
A text message can be erased by pressing
briefly on the OK button on the turn signal
lever.

Introduction
Collision Warning with Full Auto-brake and
Pedestrian Detection is designed to assist the
driver if there is a risk of a collision with a
pedestrian, a vehicle ahead that is at a stand-
still or one that is moving in the same direction
as your vehicle.
Collision Warning consists of the following
three functions:
•Collision Warning warns the driver of a
potential collision situation.
•Brake Support helps the driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision with a pedestrian or
another vehicle cannot be avoided and the
driver does not apply the brakes in time or
steer around the person/vehicle. Auto-
brake can help prevent a collision or
reduce the speed at which a collision
occurs.
Since Collision Warning with Full Auto-brake
and Pedestrian Detection is activated in cir-
cumstances 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 eventually
occurring increase considerably.
The Collision Warning and City Safety™ sys-
tems supplement each other. See page 154 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 sys-
tem by driving toward a person or object.
This could result in serious injury or death.
WARNING
•Collision Warning does not work in all
driving, traffic, weather and road condi-
tions. It does not react to vehicles not
traveling in the same direction as your
vehicle.
•Collision Warning does not react to ani-
mals.
•Warnings are only provided when the
risk of collision is high. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using Collision Warning.
•Collision Warning will not provide a
warning or brake the vehicle for pedes-
trians at speeds above 50 mph
(80 km/h).

WARNING
•Collision Warning will not provide a
warning or brake the vehicle for pedes-
trians 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 supplemen-
tary 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 Collision Warning
system's components must only be
performed by a trained and qualified
Volvo technician.
Function
Function overview
Audio-visual warning signals, collision risk
Radar sensor
Camera
Collision WarningThe radar sensor and the camera work
together to detect a pedestrian, stationary
vehicles and vehicles that are moving in the
same direction as your vehicle. If there is a risk
of collision with a vehicle or a pedestrian, the
driver is alerted by a flashing red warning light
and an audible warning signal. Collision warn-
ing is active at speeds above 3 mph (4 km/h).
Brake SupportIf 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 expe-
rienced 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 determines
that the driver has not applied adequate pres-
sure on the brake pedal.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes or begun to steer around the
vehicle or pedestrian, 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.
NOTE
The auto-brake and brake support functions
are always on and cannot be turned off.

Operation
Settings are made by pressing MY CAR on the
center console control panel and using the
menus displayed.
Activating/deactivating both warning
signals
To switch Collision Warning's audible and vis-
ual signals on or off at the same time, press
MY CAR on the center console control panel
and go to Settings

support systems
Collision Warning. If
Collision Warning is on, the system will perform
a self-test each time the engine is started by
briefly illuminating the warning light. See page
191 for a description of the menu system.
When the engine is switched on, the Collision
Warning setting that was being used when it
was switched off will be the default setting.
NOTE
The auto-brake and pedestrian detection
features are always on, even if the audible
and visual warning signals have been deac-
tivated.
Activating/deactivating the audible
warning signal only
The audible warning signal can be activated/
deactivated by pressing MY CAR on the centerconsole control panel and going to Settings

Warning distance.
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to Normal.
WARNING
•The setting Short should only be used
in situations where traffic is light and
moving at low speeds.
•Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
•For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 151.
NOTE
•When Adaptive Cruise Control is used,
the warning light and signal will be used
by that function, even if the warnings
provided by Collision Warning have
been deactivated by the driver.
•In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting
Long has been selected.
Checking settingsThe current Collision Warning settings can be
checked by pressing MY CAR on the center
console control panel and going to Settings
Car settingsDriver support systems
Collision Warning.
Limitations
Strong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult 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 DSTC systems provide the
best possible braking effect while helping to
maintain stability.
NOTE
The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger 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 system.
WARNING
•In certain situations, the system cannot
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 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 and provides warnings
and braking effect most effectively at
speeds up to 30 mph (50 km/h). For sta-
tionary or slow-moving vehicles, the
system functions best if your vehicle’s
speed is below approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions or in 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 146.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 162). This causes the system to pro-
vide later warnings, 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 Collision
Warning 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 vehi-
cle 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 limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 168), and Lane Departure Warning (see
page 171).
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
