City Safety™
04
188* 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 below
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 192.
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 80 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
Settings
Car settingsDriving support
systems
City Safety. Select the Off option.
For more information on the menu system MY
CAR, see page 144).
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.

Collision Warning with Auto Brake & Pedestrian Protection*
04
192* Option/accessory, for more information, see Introduction.
General
Collision Warning with Auto Brake and Pedes-
trian Detection is designed to assist the driver
when there is a risk of colliding with a pedes-
trian or vehicles in front that are 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 188.
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.

Activating/deactivating warning signalsThe warning lamp is activated automatically
when the engine is started if the system is
switched on.
The warning sound can be activated/deacti-
vated separately using the options for
On orOff in the menu system MY CAR under
Settings
Car settingsDriving support
systems
Warning sound if risk of
collision.
Set warning distanceThe warning distance regulates the distance at
which the visual and acoustic warnings are
deployed. Select one of the options from
Long, Normal or Short in the menu system
MY CAR under Settings
Car settings
Driving support systemsCollision
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 185.
NOTE
Even if the warning distance has been set toLong warnings could be perceived as being
late in certain situations, e.g. when there are
large differences in speed or if vehicles 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
Driving support systems
Collision Warning, see page 144.
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.

* Option/accessory, for more information, see Introduction.195
WARNING
Warnings and brake interventions could be
implemented late or not at all if the traffic
situation or external influences mean that
the radar or camera sensor cannot detect a
pedestrian or a vehicle in front correctly.
The sensor system has a limited range for
pedestrians and the system therefore pro-
vides effective warnings and brake inter-
ventions at vehicle speeds up to 50 km/h.
For stationary or slow-moving vehicles,
warnings and brake interventions are effec-
tive at vehicle speeds up to 70 km/h.
Warnings for stationary or slow-moving
vehicles could be disengaged due to dark-
ness or 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 181.
If warnings are perceived as being too frequent
or disturbing then the warning distance can be
reduced. This would lead to the system warn-
ing at a later stage, which reduces the total
number of warnings.
When the car is reversing Collision Warning
with Auto Brake cannot be activated.
Collision Warning with Auto Brake is not acti-
vated at low speeds - under 4 km/h, which iswhy the system does not intervene in situations
where the car is approaching a vehicle in front
very slowly, e.g. when parking.
Driver commands are always prioritised, which
is why Collision Warning with Auto Brake does
not intervene in situations where the driver is
steering, braking or accelerating in a clear
manner, even if a collision is unavoidable.
When Auto Brake 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 Auto Brake has stopped the car, unless
the driver manages to depress the clutch pedal
beforehand.
Camera sensor limitationsThe car's camera sensor is used by the three
functions - Collision Warning with Auto Brake,
Driver Alert Control, see page 199 and Lane
Departure Warning, see page 202.
NOTE
Keep the windscreen surface in front of the
camera sensor clean from ice, snow, mist
and dirt.
Do not attach or fit anything to the wind-
screen in front of the camera sensor, as this
could reduce or prevent the function of one
or more camera-dependent systems.
The camera sensors have limitations similar to
the human eye, i.e. they "see" worse in dark-
ness, heavy snowfall or rain and in thick fog for
example. Under such conditions the functions
of camera-dependent systems could be sig-
nificantly reduced or temporarily disengaged.
Strong oncoming light, reflections in the car-
riageway, snow or ice on the road surface, dirty
road surfaces or unclear lane markings could
also significantly reduce camera sensor func-
tion when it is used to scan the carriageway
and detect pedestrians and other vehicles.
During very high temperatures the camera is
temporarily switched off for about 15 minutes
after the engine is started in order to protect
camera functionality.

Driver Alert System – DAC*
04
* Option/accessory, for more information, see Introduction.199 General information on Driver Alert
System
The Driver Alert System is intended to assist
drivers whose driving ability is deteriorating or
who are inadvertently leaving the lane they are
driving on.
The Driver Alert System consists of two differ-
ent functions, which can either be switched on
at the same time or individually:
•Driver Alert Control (DAC)
•Lane Departure Warning (LDW), see
page 202.
A switched-on function is set in standby mode
and is not activated automatically until speed
exceeds 65 km/h.
The function is deactivated again when speed
decreases to below 60 km/h.
Both functions use a camera which is depend-
ent on the lane having side markings painted
on each side.
WARNING
The Driver Alert System does not work in all
situations but is instead only intended to be
of supplementary assistance.
The driver always has ultimate responsibility
that the car is driven safely.
General information on Driver Alert
Control - DAC
The function is intended to attract the driver's
attention when he/she starts to drive less con-
sistently, e.g. if he/she becomes distracted or
starts to fall asleep.
A camera detects the side markings painted on
the carriageway and compares the section of
the road with the driver's steering wheel move-
ments. The driver is alerted if the vehicle does
not follow the carriageway evenly.
NOTE
The camera sensor has certain limitations,
see page 195.
The objective for DAC is to detect slowly dete-
riorating driving ability and it is primarily
intended for major roads. The function is not
intended for city traffic.
In some cases driving ability is not affected
despite driver fatigue. In which case there may
not be any warning issued for the driver. For
this reason it is always important to stop and
take a break in the event of any signs of driver
fatigue, irrespective of whether or not DAC
issues a warning.
NOTE
The function must not be used to extend a
driving stint. Always plan breaks at regular
intervals and ensure that you are fully
rested.
LimitationIn some cases the system may issue a warning
despite driving ability not deteriorating, for
example:
•if the driver tests the LDW function.
•in strong side winds.
•on rutted road surfaces.

Driver Alert System - LDW*
04
202* Option/accessory, for more information, see Introduction.
General information on Lane Departure
Warning - LDW
The function is intended to reduce the risk for
single-vehicle accidents – accidents where, in
certain situations, the vehicle leaves the car-
riageway and is in danger of driving either into
a ditch or into oncoming traffic.
LDW consists of a camera that detects the side
markings painted on the carriageway. The
driver is alerted by an acoustic signal if the
vehicle crosses a side marking.
Operation and function
The function is switched on or off by means of
a switch on the centre console. An indicator
lamp in the button illuminates when the func-
tion is switched on.
The trip computer display shows
Lane Depart
Warn Standby <65 km/h when the function is
in standby mode due to speed being below 65
km/h.
The LDW function is activated automatically
from standby mode after the camera has scan-
ned in the carriageway's side markings and
speed exceeds 65 km/h. The trip computer
display then shows
Lane Depart Warn
Available.If the camera can no longer detect the carria-
geway's side markings the display shows
Lane Depart Warn Unavailable.
If speed decreases to below 60 km/h then the
function resumes standby mode and the dis-
play shows
Lane Depart Warn Standby <65
km/h.
If the vehicle crosses the left or right-hand side
marking of the carriageway without due cause
then the driver is alerted by an acoustic signal.
No warning is given in the following situations:
•Direction indicators activated
•The driver has his/her foot on the brake
pedal1
•In the event of the accelerator pedal being
depressed rapidly1
•In the event of rapid steering wheel move-
ments1
•In the event of a sudden turn so that the car
rolls.
The camera sensor also has certain limitations.
For more information, see page 195.
1A warning is still given when Increased sensitivity is selected, see page 204.

Park assist camera*
04
208* Option/accessory, for more information, see Introduction.
General
The parking camera is an assist system and is
activated when reverse gear is engaged (can
be changed in the settings menu, see
page 144).
The camera image is shown on the centre con-
sole's screen.
WARNING
•The parking camera serves as an aid. It
does not relieve the driver of responsi-
bility when reversing.
•The camera has blind spots, where
obstacles cannot be detected.
•Be aware of people and animals in the
vicinity of the car.
CAM button location.
The camera shows what is behind the car and
if something appears from the sides.
The camera shows a wide area behind the car
and part of the bumper and any towbar.
Objects on the screen may appear to tilt slightly
- this is normal.
NOTE
Objects on the display screen may be closer
to the car than they appear to be on the
screen.
If another view is active the parking camera
system takes over automatically and the cam-
era image is displayed on the screen.When reverse gear is engaged two unbroken
lines are shown graphically which illustrate
where the car's rear wheels will roll with the
current steering wheel angle, this facilitates
tight parking, reversing into tight spaces and
for hitching a trailer. The car's approximate
exterior dimensions are also illustrated by two
dashed lines, the park assist lines can be deac-
tivated in the settings menu.
If the car is also equipped with parking assis-
tance sensors* then their information is dis-
played graphically as coloured fields in order to
illustrate the distance to detected obstacles,
see page 205.
The camera is active approx. 5 seconds after
reverse gear has been disengaged or until the
car's speed exceeds 10 km/h.
