166* Option/accessory, for more information, see Introduction.
Different time intervals to the
vehicle in front can be
selected and shown in the
display as 1-5 horizontal lines
- the more lines the longer the
time interval. One line corre-
sponds to
approximately 1 second to the vehicle in front,
5 lines approximately 3 seconds.
The number of lines for the
selected time interval is
shown during the setting itself
and for several seconds after-
wards. Then a smaller scale
version of the symbol is
shown to the right of the dis-
play. The same symbol is also shown when
adaptive cruise control is activated.
NOTE
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
The set time interval is also used by the
adaptive cruise control function, see
page 156.
Only use the time interval that is allowed in
accordance with local traffic regulations.
Limitations
The function uses the same radar sensor as
adaptive cruise control and the collision warn-
ing system. For more information on the radar
sensor and its limitations, see page 160.
NOTE
Strong sunlight, reflections or strong varia-
tions in light intensity, as well as wearing
sunglasses, could mean that the warning
light in the windscreen cannot be seen.
Poor weather or winding roads could affect
the radar sensor's capacity to detect vehi-
cles in front.
The size of other vehicles could also affect
detection capacity, e.g. motorcycles. This
could mean that the warning lamp illumi-
nates at a shorter distance than the setting
or that the warning is temporarily absent.
Extremely high speeds can also cause the
lamp to illuminate at a shorter distance than
that set due to limitations in sensor range.

City Safety™
04
168* Option/accessory, for more information, see Introduction.
General
City Safety™ is a function for helping the driver
to avoid a collision when driving in queues,
amongst other things, when changes in the
traffic ahead, combined with a lapse in atten-
tion, could lead to an incident.
The function is active at speeds
under50 km/h and it helps the driver by auto-
matically braking the car in the event of immi-
nent risk of collision with vehicles in front,
should the driver not react in time by braking
and/or steering away.
City Safety™ is activated in situations where
the driver should have started braking earlier,
which is why it cannot help the driver in every
situation.
City Safety™ is designed to be activated as
late as possible in order to avoid unnecessary
intervention.
City Safety™ must not be used as an excuse
for the driver to change his/her driving style. If
the driver solely relies on City Safety™ to do
the braking, there will be a collision sooner or
later.
The driver or passengers normally only notice
City Safety™ if a situation arises where the car
is extremely close to being in a collision.If the car is also equipped with a Collision
Warning function with Auto Brake*, these two
systems complement each other. For more
information on Collision Warning function with
Auto Brake, see page 173.
IMPORTANT
Maintenance and replacement of City
Safety™ components must only be per-
formed by a workshop - an authorised Volvo
workshop is recommended.
WARNING
City Safety™ does not engage in all driving
situations or traffic, weather or road condi-
tions.
City Safety™ does not react to vehicles
driving in a different direction from the car,
to small vehicles, motorcycles and bicycles
or to humans and animals.
City Safety™ can prevent collision at a
speed difference of less than 15 km/h - at a
higher speed difference, it is only possible
to reduce collision speed. In order to obtain
full brake function, the driver must depress
the brake pedal.
Never wait for City Safety™ to engage. The
driver always bears responsibility for main-
taining the proper distance and speed.
Function
Laser sensor transmitter and receiver window1.
City Safety™ detects the traffic in front of the
car with a laser sensor fitted in the top edge of
the windscreen. If there is an imminent risk of
collision, City Safety™ will automatically brake
the car, which may be experienced as sudden
braking.
If the speed difference is 4-15 km/h in relation
to the vehicle in front then City Safety™ can
completely prevent a collision.
City Safety™ activates a short, sharp braking
and stops the car in normal circumstances, just
behind the vehicle in front. For most drivers this
is well outside normal driving style and may be
experienced as being uncomfortable.
1NOTE: The illustration is schematic - details may vary depending on car model.

If the difference in speed between the vehicles
is greater than 15 km/h then City Safety™ may
not prevent the collision on its own. To obtain
full brake force, the driver must depress the
brake pedal. This could then make it possible
to prevent a collision, even at speed differen-
ces above 15 km/h.
When the function is activated and brakes, the
instrument panel display shows a message to
the effect that the function is/has been active.
NOTE
The brake lights come on when City
Safety™ brakes the car.
Operation
NOTE
The City Safety™ function is always ena-
bled after the engine has been started via
key position I and II (see page 78 on key
positions).
On and OffIn certain situations, it may advisable to disable
City Safety™, e.g. where leafy branches could
sweep over the bonnet and/or windscreen.
After starting the engine City Safety™ can be
deactivated as follows:
•Using MY CAR on the centre console dis-
play screen with its menu system, search
and locate Settings
Car settings
Driver support systemsCity Safety.
Select the
Off option. For more information
on the menu system MY CAR, see
page 202.
However, the function will be enabled the
next time the engine is started, regardless
of whether the system was enabled or dis-
abled when the engine was switched off.
WARNING
The laser sensor also transmits laser light
when City Safety™ is disabled manually.
To enable City Safety™ again:
•Follow the same procedure as for disa-
bling, but select the On option.
Limitations
The sensor in City Safety™ is designed to
detect cars and other large vehicles in front of
the car irrespective of whether it is day or night.
However, the sensor has limitations and has
poorer functionality - or none at all - in e.g.
heavy snowfall or rain, dense fog, dust storms
or snow flurries. Mist, dirt, ice or snow on the
windscreen may disrupt the function.Low-hanging objects, e.g. a flag/pennant for
projecting load, or accessories such as auxili-
ary lamps and bull bars that are higher than the
bonnet limit the function.
The laser light from the sensor in City
Safety™ measures how the light is reflected.
The sensor cannot detect objects with low
reflection capacity. The rear sections of the
vehicle generally reflect the light sufficiently
thanks to the number plate and rear light reflec-
tors.
On slippery road surfaces the braking distance
is extended, which may reduce the capacity of
City Safety™ to avoid a collision. In such sit-
uations the ABS and DSTC systems will pro-
vide best possible braking force with main-
tained stability.
When your own car is reversing, City Safety™
is temporarily deactivated.
City Safety™ is not activated at low speeds -
under 4 km/h, which is why the system does
not intervene in situations where a vehicle in
front is being approached very slowly, e.g.
when parking.
Driver commands are always prioritised, which
is why City Safety™ does not intervene in sit-
uations where the driver is steering or acceler-
ating in a clear manner, even if a collision is
unavoidable.

171 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 168 shows sensor
location).
For more information on the laser sensor, see
page 9.
Symbols and messages in the display
In conjunction with automatic braking by the
City Safety™ system, one or more symbols
may illuminate on the instrument panel and a
message may appear on its display.
A text message can be acknowledged by
briefly pressing the OK button on the direction
indicator stalk.

* Option/accessory, for more information, see Introduction.173 General
"Collision Warning with Auto Brake & Pedes-
trian Detection" is an aid to assist the driver
when there is a risk of colliding with a pedes-
trian or vehicle in front that is stationary or
moving in the same direction.
Collision Warning with Auto Brake & Pedestrian
Detection is activated in situations where the
driver should have started braking earlier,
which is why it cannot help the driver in every
situation.
Collision Warning with Auto Brake & Pedestrian
Detection is designed to be activated as late as
possible in order to avoid unnecessary inter-
vention.
Collision Warning with Auto Brake & Pedestrian
Detection may prevent a collision or reduce the
collision speed.
Collision Warning with Auto Brake & Pedestrian
Detection must not be used as an excuse for
the driver to change his/her driving style. If the
driver solely relies on Collision Warning with
Auto Brake to do the braking, there will be a
collision sooner or later.
Two system levelsDepending on how the car equipped, the Col-
lision Warning with Auto Brake & Pedestrian
Detection function may appear in two variants:
Level 1 and Level 2.
Level 1The driver is merely warned of occurring obsta-
cles by means of visual and acoustic signals -
no automatic braking intervenes, the driver
must himself brake.
Level 2The driver is warned of occurring obstacles by
means of visual and acoustic signals - the car
is braked automatically if the driver himself
does not act within a reasonable time.
IMPORTANT
Maintenance of components included in
Collision Warning with Auto Brake & Pedes-
trian Detection must only be carried out in a
workshop - an authorised Volvo workshop
is recommended.

Collision Warning with Auto Brake & Pedestrian Protection*
04
174* Option/accessory, for more information, see Introduction.
The collision warning system and City
Safety™ complement each other. For more
information on City Safety™, see page 168.
1 - Collision warningThe driver is first warned of a potentially immi-
nent collision.
The collision warning system detects pedes-
trians, stationary vehicles as well as vehicles
driving in the same direction in front of the car.
If there is a risk of collision with a pedestrian or
a vehicle, the driver's attention is attracted with
a flashing red warning signal (no. [1] in the illus-
tration on page 173) and an acoustic signal.
2 - Brake support2
If the risk of collision has increased further after
the collision warning then the brake support is
activated.
This means that the brake system is prepared
for rapid braking by applying the brakes lightly,
which may feel like a slight jolt.
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.
3 - Auto Brake2
The automatic brake function is activated last.
If in this situation the driver has not yet started
to take evasive action and the risk of collision
is imminent then the automatic braking func-
tion is deployed - this takes place irrespective
of whether or not the driver brakes. 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 a collision.WARNING
The collision warning system does not
engage in all driving situations or traffic,
weather or road conditions. The collision
warning system does not react to vehicles
driving in another direction to the car or to
animals.
Warning only activated in the event of a high
risk for collision. This section "Function"
and the section "Limitations" inform about
limitations that the driver must be aware of
before using the Collision Warning system
with Auto Brake.
Warnings and brake interventions for
pedestrians are switched off at vehicle
speeds exceeding 80 km/h.
Warnings and brake interventions for
pedestrians do not work in darkness and
tunnels - not even when streetlights are lit.
The auto-brake function can prevent a col-
lision or reduce collision speed. To ensure
full brake performance, the driver should
always depress the brake pedal - even when
the car auto-brakes.
Never wait for a collision warning. The driver
is always responsible that the correct dis-
tance and speed are maintained - even
when the collision warning system with
auto-brake is used.

* Option/accessory, for more information, see Introduction.175 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 an assistance tool.
This function cannot detect all pedestrians
in all situations and it cannot see e.g. parti-
ally obscured pedestrians, people in cloth-
ing 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.
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 202.
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:
•Use the menu system MY CAR via the
centre console display to search for

Collision Warning -
there, select
On or Off.
An activated function is tested every time the
engine is started by briefly illuminating the sep-
arate lights for the warning lamp (no. [1] in the
illustration on page 173).
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.
