Adaptive cruise control*
04
180* Option/accessory, for more information, see Introduction.
NOTE
Activation of the cruise control below
30 km/h requires a vehicle in front within a
reasonable distance.
For shorter stops in connection with inching in
slow traffic or at traffic lights driving is auto-
matically resumed if the stops do not exceed
about 3 seconds - if it takes longer before the
car in front starts moving again then the cruise
control is set in standby mode. The driver must
then re-activate the cruise control in one of the
following ways:
•Press the steering wheel button .
or
•Press the accelerator pedal and accelerate
up to at least about 4 km/h (normal walking
pace).
The cruise control will then resume following
the vehicle in front.
NOTE
The cruise control can hold the car station-
ary for a maximum of 2 minutes - then the
parking brake is applied and the cruise con-
trol is disengaged.
•The driver has to release the parking
brake before the cruise control can be
reactivated.
Change of target
If the target vehicle in front suddenly turns then
there may be stationary traffic in front.
When the cruise control is following another
vehicle at speeds below 30 km/h and changes
target from a moving to a stationary vehicle, the
cruise control will slow down for the stationary
vehicle.
WARNING
When the cruise control is following another
vehicle at speeds in excess of 30 km/h and
the target is changed from a moving vehicle
to a stationary vehicle, the cruise control will
ignore the stationary vehicle and instead
select the stored speed.
•The driver must intervene him/herself
and brake.
Automatic standby mode with change of
target
Cruise control is disengaged and set in
standby mode:
•when the speed is below 15 km/h and
cruise control is not sure whether the target
object is a stationary vehicle or some other
object, e.g. a speed bump.
•when the speed is below 15 km/h and the
vehicle in front turns off so the cruise con-
trol no longer has a vehicle to follow.
Automatic braking ceases when
stationary
In certain situations the cruise control inter-
rupts braking when stationary. This means that
the foot brake is released and the driver must
brake himself/herself.
Cruise control releases the foot brake and is
set in standby mode when:
•the driver puts his/her foot on the brake
pedal
•the parking brake is applied
•the gear selector is moved to P, N or R
position
•the driver sets the cruise control in standby
mode.

City Safety™
04
189
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.

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 188).
•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
188) - 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.

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.

Function overview1.
Audio-visual warning signal in the event of
a collision 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 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, 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 suffi-
cient 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 144.
NOTE
The Brake Support and Auto Brake func-
tions are always enabled - they cannot be
deactivated.

should be switched on or off: Search with the
menu system MY CAR via the centre console

Driving support systems
Collision Warning. For information on the
menu system, see page 144.
An activated function is tested at each engine
start by briefly illuminating the warning lamp's
separate points of light.
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.

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.

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 a means of assistance.
It cannot detect all pedestrians in all situa-
tions and it cannot see e.g. partially
obscured pedestrians, people in clothing
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.
Fault tracing and action
If the display shows the message Windscreen
Sensors blocked then this means that the
camera sensor is blocked and cannot detect
pedestrians, vehicles or road markings in front
of the car.In turn this means that the Collision Warning
with Auto Brake, Lane Departure Warning and
Driver Alert Control functions are not operating
with full functionality.
The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The windscreen sur-
face in front of the
camera is dirty or
covered with ice or
snow.Clean the wind-
screen surface in
front of the camera
from dirt, ice and
snow.
Thick fog, heavy rain
or snow means that
the camera does not
work sufficiently
well.No action. At times
the camera does not
work during heavy
rain or snowfall.

General
Economical drivingDriving economically means driving smoothly
while thinking ahead and adjusting your driving
style and speed to the prevailing conditions.
•Drive in the highest gear possible, adapted
to the current traffic situation and road -
lower engine speeds result in lower fuel
consumption.
•Avoid driving with open windows.
•Avoid sudden unnecessary acceleration
and heavy braking.
•Remove unnecessary items from the car -
the greater the load the higher the fuel con-
sumption.
•Use engine braking to slow down, when it
can take place without risk to other road
users.
•A roof load and ski box increase air resis-
tance, leading to higher fuel consumption
- remove the load carriers when not in use.
•Do not run the engine to operating tem-
perature at idling speed, but rather drive
with a light load as soon as possible - a
cold engine consumes more fuel than a
warm one.
•Cars with the D5 engine and 6-speed man-
ual transmission or DRIVe engine and 6-
speed manual transmission are started in2nd gear under normal conditions on level
ground.
For more information and further advice, see
the pages 12 and 363.
WARNING
Never switch off the engine while moving,
such as downhill, this deactivates important
systems such as the power steering and
brake servo.
Driving in waterThe car can be driven through water at a maxi-
mum depth of 25 cm at a maximum speed of
10 km/h. Extra caution should be exercised
when passing through flowing water.
During driving in water, maintain a low speed
and do not stop the car. When the water has
been passed, depress the brake pedal lightly
and check that full brake function is achieved.
Water and mud for example can make the
brake linings wet resulting in delayed brake
function.
•Clean the electric contacts of the electric
engine block heater and trailer coupling
after driving in water and mud.
•Do not let the car stand with water over the
sills for any long period of time - this could
cause electrical malfunctions.
IMPORTANT
Engine damage can occur if water enters
the air filter.
In depths greater than 25 cm, water could
enter the transmission. This reduces the
lubricating ability of the oils and shortens
the service life of these systems.
In the event of the engine stalling in water,
do not try restart - tow the car from the water
to a workshop - an authorised Volvo work-
shop is recommended. Risk of engine
breakdown.
Engine, gearbox and cooling systemUnder special conditions, for example hard
driving in hilly terrain and hot climate, there is
a risk that the engine and drive system may
overheat - in particular with a heavy load.
For information about overheating when driv-
ing with a trailer, see page 283.
•Remove any auxiliary lamps from in front
of the grille when driving in hot climates.
•If the temperature in the engine's cooling
system is too high the instrument panel's
warning symbol is illuminated and there is
a text message displayed there
High
engine temp Stop safely - stop the car in
a safe way and allow the engine to run at
idling speed for several minutes to cool
down.

tank may need to be vented in the workshop in
order to restart the engine after fuelling.
Once the engine has stopped due to fuel star-
vation, the fuel system needs a few moments
to carry out a check. Do this before starting the
engine, once the fuel tank has been filled with
diesel:
1. Insert the remote control key in the ignition
switch and push it in to the end position
(see page 80).
2.
Press the START button without depress-
ing the brake and/or clutch pedal.
3. Wait approx. 1 minute.
4. To start the engine: Depress the brake and/
or clutch pedal and then press the
START button again.
NOTE
Before filling with fuel in the event of fuel
shortage:
•Stop the car on as flat/level ground as
possible - if the car is tilting there is a
risk of air pockets in the fuel supply.
Draining condensation from the fuel filterThe fuel filter separates condensation from the
fuel. Condensation can disrupt engine opera-
tion.The fuel filter must be drained at the intervals
specified in the Service and Warranty Booklet
or if you suspect that the car has been filled
with contaminated fuel.
IMPORTANT
Certain special additives remove the water
separation in the fuel filter.
Diesel particle filter (DPF)Diesel cars are equipped with a particle filter,
which results in more efficient emission con-
trol. The particles in the exhaust gases are col-
lected in the filter during normal driving. So-
called "regeneration" is started in order to burn
away the particles and empty the filter. This
requires the engine to have reached normal
operating temperature.
Regeneration of the filter is automatic and nor-
mally takes 10-20 minutes. It may take a little
longer at a low average speed. Fuel consump-
tion may increase slightly during regeneration.
Regeneration in cold weatherIf the car is frequently driven short distances in
cold weather then the engine does not reach
normal operating temperature. This means that
regeneration of the diesel particle filter does
not take place and the filter is not emptied.When the filter has become approximately
80% full of particles, a warning triangle on the
instrument panel illuminates, and the message
Soot filter full See manual is shown on the
instrument panel display.
Start regeneration of the filter by driving the car
until the engine reaches normal operating tem-
perature, preferably on a main road or motor-
way. The car should then be driven for approx-
imately 20 minutes more.
NOTE
A smaller reduction of engine power may be
noticed temporarily during regeneration.
When regeneration is complete the warning
text is cleared automatically.
Use the parking heater* in cold weather so that
the engine reaches normal operating tempera-
ture more quickly.
IMPORTANT
If the filter fills up with particles then it can
be difficult to start the engine and the filter
will be incapable of functioning. Then there
is a risk that the filter will have to be
replaced.
