Optimal sound reproductionThe audio system is calibrated for optimal
sound reproduction using digital signal pro-
cessing.
This calibration takes into account factors such
as the speakers, amplifier, cabin acoustics, the
listeners' seating positions, etc., for each com-
bination of vehicle/audio system.
There is also a dynamic calibration that takes
into consideration the volume level, radio
reception, and the speed of the vehicle.

Introduction
The Dynamic Stability and Traction Control
system (DSTC) consists of a number of func-
tions designed help reduce wheel spin, coun-
teract skidding, and to generally help improve
directional stability.
CAUTION
A pulsating sound will be audible when the
system is actively operating and is normal.
Traction control (TC)This function is designed to help reduce wheel
spin by transferring power from a drive wheel
that begins to lose traction to the wheel on the
opposite side of the vehicle (on the same axle).
TC is most active at low speeds.
This is one of DSTC's permanent functions and
cannot be switched off.
Active Yaw Control (AYC)This function helps maintain directional stabil-
ity, for example when cornering, by braking
one or more of the wheels if the vehicle shows
a tendency to skid or slide laterally.
This is one of DSTC's permanent functions and
cannot be switched off.
Spin control (SC)The spin control function is designed to help
prevent the drive wheels from spinning while
the vehicle is accelerating.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily switch off this function for maxi-
mum tractive force.
WARNING
The car's handling and stability characteris-
tics will be altered if the spin control function
has been disabled.

Symbols in the instrument panel
If the symbols and are displayed
at the same time, read the message in the
information display.
If the symbol
appears alone, it may
appear as follows:
•If the symbol flashes, this indicates that the
stability system is actively functioning to
help counteract wheel spin and/or a skid.
•If the symbol remains on for approximately
2 seconds after the engine has been
started, this indicates that the system is
performing a self-diagnostic test.
WARNING
The stability system is intended to help
improve driving safety. It supplements, but
can never replace, the driver's judgment
and responsibility when operating the vehi-
cle. Speed and driving style should always
be adapted to traffic and road conditions.

158* Option/accessory, for more information, see Introduction.
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.
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
settings
Steering force level. For a
description of the menu system, see
page 122.
NOTE
This steering force level menu function can-
not be accessed when the vehicle is in
motion.

Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.161 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 170).
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
162* 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 165.
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 173) 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.

Situations where ACC may not function
optimally
WARNING
•The radar sensor has a limited field of
vision. In some situations it may detect
a vehicle later than expected or not
detect other vehicles at all.
•If ACC is not functioning properly,
cruise control will also be disabled.
G021414
Radar sensor's field of vision (gray)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters the
lane between your vehicle and the one that
the system has already detected.
Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.
In curves, the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.

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 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.

Collision warning with Auto-brake*
04

* Option/accessory, for more information, see Introduction.173 Introduction
Collision Warning with Auto-brake is designed
to assist the driver if there is a risk of a collision
with a vehicle ahead that is at a standstill or
moving in the same direction as your vehicle.
Collision Warning consists of the following
three functions:
•Collision Warning warns the driver of a
potential collision situation.
•Brake Support helps the driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision cannot be avoided. Auto-
brake cannot prevent a collision but can
reduce the speed at which a collision
occurs.
WARNING
The auto-brake function cannot prevent a
collision but instead is intended to reduce
speed at the moment of impact. For full
braking effect, driver must apply the brakes.
WARNING
•Collision Warning does not work in all
driving, traffic, weather and road condi-
tions. It does not react to vehicles not
traveling in the same direction as your
vehicle.
•The collision warning system is not
designed to detect pedestrians.
•Warnings are only provided when the
risk of collision is high. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using Collision Warning.
•The auto-brake function can help
reduce the speed at impact but the
driver should always apply the brakes
for the best possible braking effect,
even if auto-brake is actively applying
the brakes.
•Never wait for a collision warning. This
system is designed to be a supplemen-
tary 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, even when the colli-
sion warning system is in use.
•Maintenance of the Collision Warning
system's components must only be
performed by a trained and qualified
Volvo technician.
