A/C – ON/OFFWhen the indicator light in the
button is on, the air condition-
ing is controlled automati-
cally. This cools/heats and
dehumidifies the incoming air.
When the indicator light in the
button is off, the air condition-
ing is disengaged. Other functions are still con-
trolled automatically. When maximum
defroster is selected, the air conditioning sys-
tem is set for maximum blower speed and
dehumidification.
DefrosterThis function defrosts/de-ices
the windshield and front side
windows. The indicator light
in the defroster button lights
when the function is active.
•Blower speed increases automatically and
the air conditioning will switch on (if not
already on and if the passenger compart-
ment blower is not turned off) to dehumid-
ify the air in the passenger compartment.
Air conditioning can be switched off by
pressing the AC button.
•Recirculation will not function while defrost
is engaged.The climate system will return to its previous
settings when the defroster function is
switched off.
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 timer. See page
131 for a description of the menu system.
NOTE
When Defroster is selected, recirculation is
always deactivated.
Interior Air Quality System–IAQS*This system consists of a multifilter and an air
quality sensor. The filter helps remove gases
and particles from the incoming air, thereby
reducing the amounts of odors and contami-
nants entering the vehicle. The air quality sen-
sor detects increased levels of contaminants in
the outside air. When the air quality sensor
detects contaminated outside air, the air intake
closes and the air inside the passenger com-
partment is recirculated, i.e., no outside air
enters the vehicle. The filter also cleans recir-
culated passenger compartment air. When the
AUTO button is depressed the air quality sen-
sor is always engaged.

Active chassis (Four C)
Active chassis, Four-C (Continuously Con-
trolled Chassis Concept), 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

Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.153 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 163).
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.

154* Option/accessory, for more information, see Introduction.
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 158.
Adaptive Cruise Control can be put in active
mode at any permitted speed. However, if the
vehicle's speed falls below 18 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
2. The driver will
then have to maintain a safe distance to the
vehicle ahead.
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 40% 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 172) 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.
2Does not apply to vehicles with the optional Queue Assist. See page 157 for more information.

Fault tracing and actions
If the message Radar blocked See manual is
displayed, this means that the radar signals
from the sensor have been obstructed and that
a vehicle ahead cannot be detected.
This, in turn, means that the functions of the
ACC, Distance Alert, and Collision Warning
System with Auto-brake and Pedestrian
Detection will not function.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the
radar.

City Safety™
04
166
Introduction
City Safety™1 is a support system designed to
help the driver avoid low speed collisions when
driving in slow-moving, stop-and-go traffic.
City Safety™ is not active if your vehicle’s
speed is below approximately 2 mph (4 km/h).
This means that City Safety™ will not react if
your vehicle approaches another vehicle at
very low speed, for example, when parking.
The function is active at speeds up to approx-
imately 18 mph (30 km/h) and assists the driver
by applying the brakes automatically, thereby
avoiding or helping to reduce the effects of a
collision.
City Safety™ is designed to intervene as late
as possible to help avoid unnecessary activa-
tion.
City Safety™ triggers brief, forceful braking if a
low-speed collision is imminent. However, the
system will not intervene in situations where
the driver actively steers the vehicle or applies
the brakes, even if a collision cannot be avoi-
ded. This is done in order to always give the
driver’s actions highest priority.
City Safety™ activates in situations where the
driver has not applied the brakes in time, whichmeans that the system cannot help the driver
in all situations.
City Safety™ should not be used to alter the
way in which the driver operates the vehicle.
The driver should never rely solely on this sys-
tem to safely stop the vehicle.
Normally, the occupants of the vehicle will not
be aware of City Safety™ except when the
system intervenes when a low-speed collision
is imminent.
If the vehicle is also equipped with the optional
Collision Warning with Full Auto-brake and
Pedestrian Detection system, the two systems
interact. For more information about the Colli-
sion Warning with Auto-brake system, see
page 171.WARNING
•City Safety™ is a supplemental aid to
the driver. It can never replace the
driver’s attention to traffic conditions or
his/her responsibility for operating the
vehicle in a safe manner.
•City Safety™ does not function in all
driving situations or in all traffic, weather
or road conditions.
•City Safety™ only reacts to vehicles
traveling in the same direction as your
vehicle and does not react to small vehi-
cles, bicycles or motorcycles or to peo-
ple or animals.
•City Safety™ is not activated when your
vehicle is backing up.
•City Safety™ functions at speeds up to
18 mph (30 km/h). This system can help
prevent a collision if the difference in
speed between your vehicle and the
vehicle ahead is less than 9 mph
(15 km/h). If the difference in speed is
greater, a collision cannot be avoided
but the speed at which the collision
occurs can be reduced. The driver must
apply the vehicle’s brakes for full brak-
ing effect.
•Never wait for City Safety™ to intervene
in a potential collision situation. The
