Adaptive cruise control*
04
172* Option/accessory, for more information, see Introduction.
WARNING
Adaptive cruise control is not a collision
avoidance system. The driver must inter-
vene if the system does not detect a vehicle
in front.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcycles.
Nor for oncoming, slow or stationary vehi-
cles and objects.
Do not use the adaptive cruise control, for
example, in city traffic, in dense traffic, at
junctions, on slippery surfaces, with a lot of
water or slush on the road, in heavy rain/
snow, in poor visibility, on winding roads or
on slip roads.
The distance to the vehicle ahead is mainly
measured by a radar sensor. Cruise control
regulates the speed with acceleration and
braking. It is normal for the brakes to emit a low
sound when they are being used by cruise con-
trol.
WARNING
The brake pedal moves when the cruise
control brakes. Do not rest your foot under
the brake pedal as it could become trapped.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time interval
set by the driver. If the radar sensor cannot see
any vehicle in front then the car will instead
maintain the cruise control's set speed. This
also happens if the speed of the vehicle in front
exceeds the cruise control's set speed.
The cruise control aims to control the speed in
a smooth way. In situations that demand sud-
den braking the driver must brake himself/her-
self. This applies with large differences in
speed, or if the vehicle in front brakes heavily.
Due to limitations in the radar sensor, braking
may come unexpectedly or not at all, see
page 177.
The adaptive cruise control can be activated to
follow another vehicle at speeds from
30 km/h
1 up to 200 km/h. If the speed falls
below 30 km/h or if the engine speed becomes
too low, the cruise control is set in standby
mode at which automatic braking ceases - the
driver must then take over himself/herself to
maintain a safe distance to the vehicle ahead.
Warning lamp - braking by driver
required
Adaptive cruise control has a braking capacity
that is equivalent to more than 40% of the car's
braking capacity.If the car needs to be braked more heavily than
cruise control capacity and the driver does not
brake, then the cruise control uses the collision
warning system's warning lamp and warning
sound (see page 189) to alert the driver that
immediate intervention is required.
NOTE
The warning lamp may be difficult to notice
in strong sunlight or when sunglasses are
being worn.
WARNING
Cruise control only warns of vehicles
detected by the radar sensor. Consequently
there may be no warning or it may be sub-
ject to a delay. Do not wait for a warning but
brake when it is necessary.
Steep roads and/or heavy loadBear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The cruise control may have dif-
ficultly in keeping the correct distance from the
vehicle ahead when driving on steep roads,
with a heavy load or with a trailer - in which
case, be extra attentive and ready to slow
down.
1Cars with automatic gearbox ("Queue Assist") can operate in the range of 0-200 km/h, see page 175.

Adaptive cruise control*
04
174* Option/accessory, for more information, see Introduction.
NOTE
If any cruise control button is held
depressed for more than approx. 1 minute
then cruise control is disengaged. The
engine must be switched off in order to reset
cruise control.
In certain situations, cruise control cannot
be activated. Then the display shows
Cruise control Unavailable, see
page 179.
Set time intervalDifferent 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 distance. One line corre-
sponds to approximately
1 second, 5 lines approximately 2.5 seconds.
The time interval is increased or decreased
with the steering wheel keypad's thumbwheel
(or the buttons
/ for cars without Speed
limiter).
At low speed, when the distances are short, the
adaptive cruise control increases the time
interval slightly.The adaptive cruise control allows the time
interval to vary noticeably in certain situations
in order to allow the car to follow the vehicle in
front smoothly and comfortably.
Note that a short time interval only allows the
driver a short time to react and take action if
any unforeseen traffic problem should arise.
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
Distance Alert is activated, see page 181.
NOTE
Only use the time interval that is allowed in
accordance with local traffic regulations.
If cruise control does not seem to react to
activation the reason may be that the time
interval to the closest vehicle prevents an
increase in speed.
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
Temporary deactivation - standby mode
Press the steering wheel button to tempo-
rarily disengage the cruise control and set it in
standby mode - set speed is shown in brackets
in the display, e.g.
(100).
Keypad without Speed limiter
Press the steering wheel button to tempo-
rarily disengage cruise control and set it in
standby mode.
Standby mode due to driver interventionCruise control is temporarily disengaged and
set in standby mode if:
•the foot brake is used
•the clutch pedal is depressed for longer
than 1 minute4
•the gear selector is moved to N position
(automatic gearbox)
•the driver maintains a speed higher than
the set speed for longer than 1 minute
The driver must then regulate the speed.
A temporary increase in speed with the accel-
erator pedal, e.g. during overtaking, does not
affect the cruise control setting - the car returns
to the last stored speed when the accelerator
pedal is released.
4Disengaging and selecting a higher or lower gear does not involve standby mode.

* Option/accessory, for more information, see Introduction.175
Automatic standby modeAdaptive cruise control is dependent on other
systems e.g. stability and traction control
(DSTC). If any of these systems stop working
then cruise control is automatically deacti-
vated.
In the event of automatic deactivation a signal
will sound and the message
Cruise control
Cancelled is shown in the display. The driver
must then intervene and adapt the speed and
distance to the vehicle ahead.
An automatic deactivation can be due to:
•engine speed is too low/high
•speed falls below 30 km/h5
•wheels lose traction
•brake temperature is high
•the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).
Resume set speedCruise control in standby mode is re-activated
with one press on the steering wheel button
- the speed is then set to the last stored
speed.
NOTE
A significant increase in speed may arise
after the speed has been resumed with .
DeactivateThe cruise control is switched off with the
steering wheel button
. The set speed is
cleared and cannot be resumed with the
button.
Keypad without Speed limiterThe cruise control is switched off with the
steering wheel button
in standby mode or
with one long press in active mode. The set
speed is cleared and cannot be resumed with
the
button.
Queue Assist ACC and automatic
gearbox*
In cars with automatic gearbox the adaptive
cruise control has more functions than in cars
with manual gearbox.
Note that the lowest programmable speed for
the cruise control is 30 km/h - even though the
cruise control is capable of following another
vehicle down to a standstill, a lower speed
cannot be selected.The following functions are available:
Extended speed range
NOTE
In order to activate the cruise control the
driver's door must be closed and the driver
must be wearing the seatbelt.
•With the automatic gearbox the cruise con-
trol can follow another vehicle within the
range of 0-200 km/h - right down to sta-
tionary and up to 200 km/h.
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 .

City Safety™
04
186
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.

Collision Warning & Pedestrian Detection with Auto Brake*
04
* Option/accessory, for more information, see Introduction.191
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 177.
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 195 and Lane
Departure Warning, see page 198.
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.

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 are started in 2nd gear
under normal conditions on level ground.For more information and further advice, see
the pages 12 and 355.
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 278.
•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.

•If the text message High engine temp
Stop engine or Coolant level low, Stop
engine is shown then the engine must be
switched off after stopping the car.
•In the event of overheating in the gearbox
a built-in protection function is activated
which, amongst other things, illuminates
the instrument panel's warning symbol and
there is a text message displayed there
Transmission hot Reduce speed orTransmission hot Stop safely - follow
the recommendation given and lower the
speed and stop the car in a safe way and
allow the engine to run at idling speed for
a few minutes to allow the gearbox to cool
down.
•If the car overheats, the air conditioning
may be switched off temporarily.
•Do not turn the engine off immediately you
stop after a hard drive.
NOTE
It is normal for the engine's cooling fan to
operate for a while after the engine has been
switched off.
Open tailgate
WARNING
Do not drive with the tailgate open. Toxic
exhaust fumes could be drawn into the car
through the cargo area.
Do not overload the batteryThe electrical functions in the car load the bat-
tery to varying degrees. Avoid using the key
position II when the engine is switched off.
Instead use the I mode - which uses less
power.
Also, be aware of different accessories that
load the electrical system. Do not use functions
which use a lot of power when the engine is
switched off. Examples of such functions are:
•ventilation fan
•windscreen wiper
•audio system (high volume)
•headlamps.
If the battery voltage is low the information dis-
play shows the text
Low battery Power save
mode. The energy-saving function then shuts
down certain functions or reduces certain
functions such as the ventilation fan and/or
audio system.
In which case, charge the battery by star-
ting the engine and then running it for atleast 15 minutes - battery charging is more
effective during driving than running the
engine at idling speed while stationary.
Before a long journey
•Check that the engine is working normally
and that fuel consumption is normal.
•Make sure that there are no leaks (fuel, oil
or other fluid).
•Check all bulbs and tyre tread depths.
•Carrying a warning triangle is a legal
requirement in certain countries.
Winter drivingCheck the following in particular before the
cold season:
•The engine coolant must contain at least
50% glycol. This mixture protects the
engine against frost erosion down to
approximately –35 °C. To achieve optimum
antifreeze protection, different types of gly-
col must not be mixed.
•The fuel tank must be kept filled to prevent
condensation.
•Engine oil viscosity is important. Oils with
lower viscosity (thinner oils) facilitate star-
ting in cold weather and also reduce fuel
consumption while the engine is cold. For
more information on suitable oils, see
page 351.
