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 control
settings
Recirculation timer. For a
description of the menu system, see
page 122.
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.

Active chassis system–Four C
04
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.

Collision warning with Auto-brake*
04

* Option/accessory, for more information, see Introduction.161 Introduction
Collision Warning with Auto-brake is designed
to assist the driver if there is a risk of a collision
with the vehicle ahead, if that vehicle is at a
standstill or moving in the same direction as
your vehicle. Auto-brake helps reduce the col-
lision speed.
Collision Warning consists of the following
three functions:
•Collision warning warns the driver of the
imminent risk of a collision.
•Brake support helpsthe driver brake effi-
ciently in a critical situation.
•Auto-brake brakes the vehicle automati-
cally if a collision cannot be avoided.
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
•The collision warning system does not
work in all driving situations, and traffic,
weather and road conditions.
•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 use.
•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 components must only be per-
formed by a trained and qualified Volvo
technician.

Function overview
Visual warning signal, collision risk
Radar sensor
Camera
Collision warningThe radar sensor and the camera work
together to detect stationary vehicles and vehi-
cles that are moving in the same direction as
your vehicle. If there is a risk of collision, the
driver is alerted by a flashing red warning light
and an audible warning signal. Collision warn-
ing is active at speeds above 5 mph (7 km/h).
Brake supportIf the risk of collision continues to increase after
the collision warning has been given, brake

support is activated. Brake support prepares
the brake system to react quickly, and the
brakes are applied slightly. This may be expe-
rienced as a light tug.
If the brakes are applied quickly, full braking
effect will be provided, even if pressure on the
brake pedal is light.
Auto-brakeIf a collision is imminent and the driver has not
applied the brakes, the auto-brake function is
activated without the driver pressing the brake
pedal. Limited brake force is applied to reduce
the vehicle’s speed when the 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.
NOTE
The auto-brake function is always on and
cannot be turned off.
Operation
Some settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 122.
On and offTo switch Collision Warning on or off, go into
the menu Car settings
Collision warning
settings and select On or Off. When the engine
is started, the setting that was selected when
it was switched off will be used.
Activating/deactivating warning signalsThe collision warning system’s audible and vis-
ual signals are activated automatically when
the engine is started if the collision warning
system is activated.
The audible warning signal can be activated/
deactivated by selecting the alternative

Off in Car settingsCollision warning
settings
Warning sound.
Setting a warning distanceThis setting determines the distance at which
the visual and audible warnings are triggered.
Select
Long, Normal or Short under Car
settings
Collision warning settings
Warning distance
The warning distance determines the level of
sensitivity used by the system. The warning
distance
Long provides an earlier warning.
Begin by using Long and if the system gives
too many warnings, try changing to
Normal.
WARNING
•The setting Short should only be used
in situations where traffic is light and
moving at low speeds.
•Collision Warning alerts the driver to the
risk of a collision but this function can-
not reduce the driver’s reaction time.
•For Collision Warning to be as effective
as possible, it is recommended that Dis-
tance Alert be set to 4 or 5, see
page 180.
NOTE
•When adaptive cruise control is used,
the warning light and signal will be used
by cruise control, even if they have been
deactivated by the driver.
•In situations where traffic is moving at
considerably different speeds, or if the
vehicle ahead brakes suddenly, warn-
ings may be considered to be late, even
if the setting
Long has been selected.
Checking settingsThe current Collision Warning settings can be
checked by going into the menu system at Car
settings
Collision warning settings. See
page 122 for more information on the menu
system.

LimitationsStrong sunlight, reflections, extreme light con-
trasts, the use of sunglasses, or if the driver is
not looking straight ahead may make the visual
warning signal in the windshield difficult to see.
For this reason, always activate the audible
warning signal in such conditions.
NOTE
The visual warning signal may be temporar-
ily disengaged in the event of high passen-
ger compartment temperature due to strong
sunlight, etc. If this occurs, the audible
warning signal will be used, even if it has
been deactivated in the menu system.
Warnings may not appear if the distance to the
vehicle ahead is very small or if steering wheel
and pedal movements are great, for example,
due to a very active driving style.
WARNING
•In certain situations, the system cannot
provide warnings or warning may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect the
vehicle ahead.
•Warnings may not be provided if the
distance to the vehicle ahead is short,
or if movements of the steering wheel/
brake pedal are great, such as during
active driving.
•The sensor system has a limited range
for stationary or slow-moving vehicles
and may therefore give delayed or no
warnings if your vehicle’s speed is
above approximately 45 mph
(70 km/h).
•Warnings for stationary or slow-moving
vehicles may not be provided in dark
conditions.
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 176.
If no warning is given, or if a warning is delayed,
Auto-brake will also not be provided or will be
delayed.
NOTE
If warnings are given too frequently, the
warning distance can be reduced (see
page 162. This causes the system to pro-
vide later warnings, which decreases the
total number of warnings provided.
The camera’s limitationsThe camera is used by Collision Warning with
Auto-brake, Driver Alert Control (see
page 183), and Lane Departure Warning (see
page 186).
NOTE
•To help protect the camera in very hot
conditions, it may be temporarily
switched off for approximately 15
minutes after the engine has been
started.
•Keep the section of the windshield in
front of the camera clean and free of ice,
snow, or condensation.

WARNING
•The camera has the same limitations as
the human eye. In other words, its
“vision is impaired” by adverse weather
conditions such as heavy snowfall,
dense fog, etc. These conditions may
reduce the function of systems that
depend on the camera or cause these
systems to temporarily stop function-
ing.
•Never place any objects, decals, etc.,
on the windshield in front of the camera.
This could reduce or block the camera’s
function, and could cause one or more
of the systems that utilize the camera to
stop functioning.
•Strong sunlight, reflections from the
road surface, ice or snow covering the
road, a dirty road surface, or unclear
lane marker lines may drastically reduce
the camera’s capacity to detect the side
of a lane or another vehicle.
Fault tracing and actions
If the message Windshield sensors
blocked is displayed, this means that the cam-
era is obscured and cannot detect vehicle or
road marker lines in front of the vehicle.
This, in turn, means that Collision Warning with
Auto-brake, Lane Departure Warning, and
Driver Alert Control will not have full function-
ality.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
CauseAction
The surface of the windshield in front of the camera is dirty or covered
with ice or snow.Clean or clear the section of the windshield in front of the camera.
Fog, heavy rain or snow is interfering with the function of the camera.No action possible. Heavy precipitation may affect the function of the
camera.

168
driver is always responsible for main-
taining a safe distance to the vehicle
ahead.
Function
Location of the laser sensor in the windshield
City Safety™ monitors traffic ahead of you
using a laser sensor mounted in the upper sec-
tion of the windshield. If a collision is imminent,
City Safety™ will automatically apply the
brakes at approximately 50% of the vehicle’s
full braking effect if you are traveling at speeds
between 2-18 mph (4-30 km/h).
•If the difference in speed between your
vehicle and the vehicle ahead is less than
approximately 9 mph (15 km/h), CitySafety™ can help prevent a collision from
taking place.
•If the difference in speed is between
approximately 10-18 mph (16-30 km/h),
City Safety™ alone cannot avoid a colli-
sion. The driver must apply the brakes for
full braking effect.
When the function activates and applies the
brakes, a message will appear in the informa-
tion display to indicate that the system is/has
been active.
NOTE
•When City Safety™ applies the brakes,
the brake lights will illuminate.
•In cases where City Safety™ has stop-
ped the vehicle, the system will then
release the brakes. The driver must
apply the brakes to keep the vehicle at
a standstill.
Using City Safety™
NOTE
The City Safety™ function is activated auto-
matically each time the engine has been
switched off and restarted.
On and OffIn certain situations, it may be desirable to
switch City Safety™ off, such as when driving
in close quarters where leaves, branches, etc.
may obscure the hood and windshield.

the START/STOP ENGINE button to start
the engine. This restarts City Safety™.
•Vehicles equipped with the optional
keyless drive: Press the START/STOP
ENGINE button to switch off the engine.
Depress the brake pedal and press the
START/STOP ENGINE button to start the
engine. This restarts City Safety™.
See page 79 for information on ignition modes.City Safety™ will be automatically switched on
the next time the engine is started, even if it was
off when the engine was switched off.
Limitations
The sensor used by City Safety™ is designed
to detect cars and other larger motor vehicles
ahead of your vehicle in both daylight and dark-
ness.
However, there are certain limitations and the
laser sensor’s function may be reduced by, for
example, heavy rain or snowfall, or by dense
fog or thick, blowing dust or snow. Condensa-
tion, dirt, ice or snow on the windshield may
also interfere with the sensor’s function.
Objects such as warning flags hanging from
long objects on the roof or accessories such as
auxiliary lights or protective arches on the front
of the vehicle that are higher than the hood may
also impede the sensor’s function.
Braking distance to the vehicle ahead increa-
ses on slippery road surfaces, which may
reduce City Safety’s capacity to avoid a colli-
sion. In situations like this, the DSTC system
(see page 156) will help provide the best pos-
sible braking capacity and stability.
City Safety™ emits infrared light and measures
the way in which the light is reflected. There-
fore, vehicles or objects with low-reflective sur-faces may not be detected. Normally, the
license plate and taillight reflectors give the
rear section of a vehicle ahead sufficient reflec-
tive surfaces to be detected.NOTE
•Keep the windshield in front of the laser
sensor free of ice, snow, dirt, etc. See
page 168.
•Snow or ice on the hood deeper than
2 inches (5 cm) may obstruct the sen-
sor. Keep the hood free of ice and snow.
•Do not mount or in any way attach any-
thing on the windshield that could
obstruct the laser sensor.
Troubleshooting
If Windshield sensors blocked appears in
the information display, this indicates that the
City Safety™ laser sensor is obstructed in
some way and cannot detect vehicles ahead of
you, which means that the system is not func-
tioning.
However, this message will not be displayed in
all situations in which the sensor is obstructed.
For this reason, the driver must ensure that the
area of the windshield in front of the sensor is
always kept clean.

WARNING
The laser sensor emits light when the igni-
tion is in mode II or higher, even if City
Safety™ has been switched off.
WARNING
Eye injury may occur if any of the following
points are not followed:
•It is essential that all pertinent instruc-
tions be followed when handling laser
instruments. Testing, repairing, remov-
ing, adjusting and/or replacing any
components in the laser sensor may
only be done by a trained and qualified
Volvo service technician.
•Do not remove the laser sensor (includ-
ing removal of the lenses). A laser sen-
sor that has been removed belongs to
laser class 3B according to standard
IEC 60825-1. Devices in laser class 3B
present a risk of injury to the eyes.
•The laser sensor’s connector must be
disconnected before the sensor is
removed from the windshield.
•The laser sensor must be mounted in
place on the windshield before con-
necting the sensor’s connector.
•Do not view the laser sensor (which
emits spreading, invisible laser beams)
with optical instruments from a distance
of less than 4 inches (100 mm).
Symbols and messages in the display
When City Safety™ automatically applies the
brakes, one or more of the symbols in the main
instrument panel may illuminate and its asso-
ciated message will be displayed.
A text message can be erased by pressing
briefly on the READ button on the turn signal
lever.
