Ventilated front seats*The ventilation system consists of fans in the
seats and backrests that draw air through the
seat upholstery. The cooling effect increases
as the air in the passenger compartment
becomes cooler.
The ventilation is controlled by the ECC sys-
tem, which takes into account the seat tem-
perature, sunlight in the passenger compart-
ment, and the ambient temperature.
The ventilation can be used at the same time
as seat heating.
The ventilation system can be activated when
the engine is running. There are three comfort
levels that produce different cooling and dehu-
midifying effects:
•Level three: press the button once for
maximum output – three indicator lights
come on.
•Level two: press the button twice for a
lower output – two indicator lights come
on.

Recirculation/air quality system
Recirculation
This function can be used to
shut out exhaust fumes,
smoke, etc from the passen-
ger compartment. The air in
the passenger compartment
is then recirculated, i.e., no air
from outside the car is taken
into the car when this function is activated. The
indicator light in the button will illuminate when
recirculation is selected.
If the air in the car recirculates for too long,
there is a risk of condensation forming on the
insides of the windows, especially in winter.
TimerThe timer function minimizes the risk of fog-
ging, or stale air when the recirculation function
is selected by automatically switching off the
function after a certain length of time, depend-
ing on the ambient temperature. Activate/
deactivate the function under Climate
settings
Recirculation time. For a
description of the menu system, see
page 124.
NOTE
When Defroster is selected, recirculation is
always deactivated.
Interior Air Quality System–IAQS*This system consists of a mul-
tifilter and an air quality sen-
sor. The filter helps remove
gases and particles from the
incoming air, thereby reduc-
ing the amounts of odors and
contaminants entering the
vehicle. The air quality sensor detects
increased levels of contaminants in the outside
air. When the air quality sensor detects conta-
minated outside air, the air intake closes and
the air inside the passenger compartment is
recirculated, i.e., no outside air enters the vehi-
cle. The filter also cleans recirculated passen-
ger compartment air. When the AUTO button
is depressed the air quality sensor is always
engaged.
Activating the air quality sensorSwitch between the three
functions by pressing the but-
ton repeatedly.
•The left orange light comes on – the air
quality sensor is disengaged.
•The center green light comes on – recircu-
lation not engaged, providing it is not
required for cooling in hot weather.
•The right orange light comes on – recircu-
lation is engaged.
NOTE
•The air quality sensor should always be
engaged in order to obtain the best air
in the passenger compartment.
•Recirculation is limited in cold weather
to avoid fogging.
•If the insides of the windows start fog-
ging, disengage the air quality sensor.
Use the defroster function to increase
airflow to the front, side, and rear win-
dows.

* Option/accessory, for more information, see Introduction.159 Active chassis (Four C)
Active chassis, Four-C (Continuously Con-
trolled Chassis Concept)1, regulates the cha-
racteristics of the shock absorbers so that the
car's driving characteristics can be adjusted.
There are three settings: Comfort, Sport and
Advanced.
NOTE
This system is available on Canadian mod-
els only.
ComfortComfort mode offers a somewhat softer ride
and the transmission shifts gears at lower rpm.
This mode is particularly suitable for long-dis-
tance highway driving. The indicator light in the
button will be on when this mode is selected.
SportIn this mode, the vehicle's body sway is
reduced during cornering and steering
response is more immediate. The transmission
shifts up at higher rpm for sportier driving. The
indicator light in the button will be on to indi-
cate that Sport mode has been selected.
AdvancedIn this mode, body sway in curves is minimal
and steering response is very direct. Gear shift-ing is done at high rpm in each gear for
dynamic and active driving.
Operation
Chassis settings
Use the buttons in the center console to
change setting. The setting in use when the
engine is switched off is activated the next time
the engine is started.
Speed-dependent steering force*
Steering force increases with the speed of the
vehicle to give the driver enhanced sensitivity.
At low speed the vehicle is easy to steer in
order to facilitate parking, etc.
Steering force can be changed under Car

Adaptive Cruise Control (ACC)*
04
162* Option/accessory, for more information, see Introduction.
Introduction
Adaptive Cruise Control (ACC) is an optional
system designed to assist the driver by main-
taining a set speed or a set time interval to the
vehicle ahead. It is primarily intended for use
on long straight roads in steady traffic, such as
on highways and other main roads.
When the driver has set the desired speed and
the time interval to the vehicle ahead, ACC
functions as follows:
•If there are no other vehicles in the lane
ahead of you, your vehicle will travel at the
set speed.
•If ACC's radar sensor detects a slower
moving vehicle in the lane ahead, the sys-
tem will adapt your vehicle's speed to help
maintain the set time interval to the vehicle
ahead. When there are no longer slower
moving vehicles ahead, your vehicle will
accelerate to resume the set speed.
If ACC is switched off completely or in standby
mode and your vehicle comes too close to
another vehicle ahead, the driver will be
warned by the Distance Alert system (see
page 171).
WARNING
•Adaptive Cruise Control cannot cover
all driving situations and traffic, weather
and road conditions. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using this feature.
•This system is designed to be a supple-
mentary driving aid. It is not, however,
intended to replace the driver's atten-
tion and judgement. The driver is
responsible for maintaining a safe dis-
tance and speed and must intervene if
Adaptive Cruise Control does not main-
tain a suitable speed or suitable dis-
tance to the vehicle ahead.
•Maintenance of ACC components may
only be performed by a trained and
qualified Volvo technician.

Adaptive Cruise Control consists of:
•A cruise control system to maintain a set
speed
•A system to maintain a set distance to the
vehicle ahead, which is expressed as a
time interval. For example, you can choose
to remain approximately 2 seconds behind
the vehicle ahead. The actual distance
required to maintain a 2-second interval
will vary according the speed of the vehi-
cles.

Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.163
WARNING
•Adaptive Cruise Control is not a colli-
sion avoidance system. The driver is
always responsible for applying the
brakes if the system does not detect
another vehicle.
•Adaptive Cruise Control does not react
to people or animals, or small vehicles
such as bicycles and motorcycles. It
also does not react to slow moving,
parked or approaching vehicles, or sta-
tionary objects.
•Do not use Adaptive Cruise Control in
demanding driving conditions such as
city driving or other heavy traffic situa-
tions, in slippery conditions, when there
is a great deal of water or slush on the
road, during heavy rain or snow, in poor
visibility, on winding roads or on high-
way on- or off-ramps.
The distance to the vehicle ahead (in the same
lane) is monitored by a radar sensor. Your vehi-
cle's speed is regulated by accelerating and
braking. The brakes may emit a sound when
they are being modulated by the adaptive
cruise control system. This is normal.
WARNING
The brake pedal moves when the adaptive
cruise control system modulates the
brakes. Do not rest your foot under the
brake pedal.
The ACC system is designed to smoothly reg-
ulate speed. However, the driver must apply
the brakes in situations that require immediate
braking. This applies when there are great dif-
ferences in speed between vehicles, or if the
vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, brak-
ing may occur unexpectedly or not at all,
see page 166.
Adaptive Cruise Control can only be put in
active mode at speeds above 20 mph
(30 km/h). If speed falls below 20 mph
(30 km/h) or if engine speed (rpm) becomes too
low, ACC disengages (goes into standby
mode) and will no longer modulate the brakes.
WARNING
When Adaptive Cruise Control is in standby
mode or is switched off completely, the
brakes will not be modulated automatically.
The driver must assume full control over the
vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force
that is equivalent to approximately 25% of the
vehicle's total braking capacity. In situations
requiring more brake force than ACC can pro-
vide and if the driver does not apply the brakes,
an audible signal from the Collision Warning
system will sound and warning light will illumi-
nate (see page 174) in the windshield to alert
the driver to react.
NOTE
Strong sunlight, reflections, extreme light
contrasts, the use of sunglasses, or if the
driver is not looking straight ahead may
make the visual warning signal in the wind-
shield difficult to see.

* Option/accessory, for more information, see Introduction.165
When the symbol on the
left side of the display
changes to
, the radar sen-
sor has detected another
vehicle ahead. The distance
to a vehicle ahead is only
regulated when this symbol (
) is illumi-
nated.
Changing the set speedAfter a speed has been set, it can be increased
or decreased by using the
or buttons.
When the system is in active mode, the
but-
ton has the same function as
, but results in
a smaller increase in speed.
NOTE
•If one of the Adaptive Cruise Control
buttons is pressed for more than
approximately one minute, ACC will be
deactivated. The engine must then be
switched off and restarted to reset ACC.
•In some situations Adaptive Cruise
Control cannot be put in active mode.
Cruise control Unavailable is shown
in the display, see page 169.
Setting a time intervalThe set time interval to vehicles ahead can be
increased by pressing
and decreased by
pressing
. The current time interval is shown
briefly in the display following adjustment.
Different time intervals can be
selected and are shown in the
display as 1–5 horizontal bars.
The greater the number of
bars, the longer the time inter-
val. One bar represents a time
interval of approximately
1 second; 5 bars is approximately
2.5 seconds. At low speeds, when the distance
to the vehicle ahead is short, ACC increases
the time interval slightly. In order to follow the
vehicle ahead as smoothly as possible, ACC
allows the time interval to vary considerably in
certain situations.
WARNING
•Only use a time interval that is suitable
in current traffic conditions.
•A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is in active
mode, see page 171 .
Standby mode (temporary deactivation)
Press to temporarily deactivate cruise con-
trol (put it in standby mode). The set speed, for
example 55 mph, is then shown in parenthe-
ses.
The previously set speed and time interval are
resumed by pressing
.
WARNING
There may be a significant increase in speed
after the button has been pressed.
When ACC is in active mode, the vehicle’s
speed increases by approximately 1 mph
(1 km/h) each additional time
is pressed.

Standby mode due to action by the driverACC is temporarily deactivated and put in
standby mode:
•when the brakes are applied
•if the gear selector is moved to N
•if the accelerator pedal is depressed for
more than 1 minute.
NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic standby modeAdaptive cruise control is linked to other sys-
tems such as the stability and traction control
system (DSTC). If this system is not functioning
properly, adaptive cruise control is automati-
cally deactivated and will go into standby
mode.
In the event of automatic deactivation, an audi-
ble signal will sound and the message
Cruise
control Cancelled is shown in the display.
The driver must then intervene and adapt the
vehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.
An automatic switch to standby mode may be
caused if:
•the vehicle's speed falls below 20 mph
(30 km/h)
•the wheels lose traction
•brake temperature is high
•engine speed (rpm) is too low or too high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Turning ACC off completely
A short press on in standby mode or a long
press in active mode turns ACC off completely.
The set speed and time interval are then
cleared from the system's memory and cannot
be resumed by pressing
.
The radar sensor and its limitations
In addition to being used by ACC, the radar
sensor is also used by Distance Alert (see
page 171) and Collision Warning with Auto-
brake (see page 174). This sensor is designed
to detect cars or larger vehicles driving in the
same direction as your vehicle, in the same
lane.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.
The radar sensor's capacity to detect vehicles
ahead is impeded:
•if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor
clean.
•if the speed of vehicles ahead is signifi-
cantly different from your own speed.

* Option/accessory, for more information, see Introduction.171 Introduction
Distance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Distance Alert is active at speeds above
approximately 20 mph (30 km/h). Time interval
information is only given for a vehicle that is
driving ahead of your vehicle in the same direc-
tion. No information is provided for vehicles
driving toward you, moving very slowly, or at a
standstill.
G017362
A smaller section of the red warning light in the
windshield glows steadily if your vehicle is
closer to the one ahead than the set time inter-
val.
NOTE
Distance Alert only monitors distance to the
vehicle ahead while Adaptive Cruise Control
is in active mode.
WARNING
Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.
