Distance Alert*
04
* Option/accessory, for more information, see Introduction.181 General
Distance Alert is a function that informs the
driver about the time interval to vehicles in
front.
Distance alert is active at speeds above
30 km/h and only reacts to vehicles driving in
front of the car, in the same direction. No dis-
tance information is provided for oncoming,
slow or stationary vehicles.
Yellow warning light.
A yellow warning lamp in the windscreen illu-
minates with a constant glow if the distance to
the vehicle in front is shorter than the set time
interval.
NOTE
Distance Alert is deactivated during the time
that Adaptive Cruise Control is active.
WARNING
Distance Alert only reacts if the distance to
the vehicle ahead is shorter than the preset
value - the speed of the driver's vehicle is
not affected.
Operation
Press the button in the centre console to switch
the function on or off. The function is switched
on if one lamp is illuminated in the button.
Some combinations of the selected equipment
leave no vacant space for a button in the centreconsole - in which case the function is handled

182* 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 approx-
imately 2.5 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 173.
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 177.
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
184* 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 of up to
30 km/h and it helps the driver by automatically
braking the car in the event of imminent 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 188.
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 window.
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.

If the difference in speed between the vehicles
is 15-30 km/h, City Safety™ may not prevent
the collision on its own. To obtain full brake
force, the driver must depress the brake pedal.
This could make it possible to prevent a colli-
sion even at speed differences 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 81 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 display
screen with its menu system, search and locate
SETUP
Car settingsDriver support
system
City Safety. Select the option Off.
(For information on the menu system MY
CAR, see page 142.)
However, the function will be enabled the next
time the engine is started, regardless of
whether the system was enabled or disabled
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 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 infrared 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 the car is reversing City Safety™ cannot
be activated.
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, braking or
accelerating in a clear manner, even if a colli-
sion is unavoidable.
ProCarManuals.com

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).

Collision Warning & Pedestrian Detection with Auto Brake*
04
188* Option/accessory, for more information, see Introduction.
General
Collision Warning and Pedestrian Detection
with Auto Brake (Collision Warning and
Pedestrian Detection with Full Auto Brake) is
designed to assist the driver when there is a
risk of colliding with a pedestrian or vehicle in
front that is stationary or moving in the same
direction.
The collision warning system has the following
three functions.
•Collision Warning – Warns the driver of a
potentially imminent collision.
•Brake Support – Assists the driver to
brake effectively in a critical situation.
•Auto Brake - Brakes the car automatically
in the event of an imminent risk of collision
with a pedestrian or vehicle in front, if the
driver does not himself/herself react in time
by braking and/or steering away. The Auto
Brake function can prevent a collision or
reduce collision speed.
The collision warning system is activated in sit-
uations where the driver should have started
braking a lot earlier, which is why the function
cannot help the driver in every situation.
Collision Warning with Auto Brake is designed
to be activated as late as possible in order to
avoid unnecessary intervention.The collision warning system must not be used
as an excuse for the driver to change his/her
driving style. If the driver solely relies on Colli-
sion Warning with Auto Brake to do the brak-
ing, there will be a collision sooner or later.
The collision warning system and City
Safety™ complement each other. For more
information on City Safety™, see page 184.
IMPORTANT
Maintenance of collision warning system
components must only be performed at a
workshop - an authorised Volvo workshop
is recommended.
WARNING
No automatic system can guarantee
100 % correct function in all situations.
Therefore, never try out the Auto brake sys-
tem by driving towards people - this may
cause serious injuries or risk death.
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. The Function section and
the section after advise about limitations of
which the driver should be aware before
using Collision Warning 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.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.

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.
