Rear Seat Entertainment - Dual Screen (RSE)–option
04``149 Introduction
The RSE system can be used at the same time
as the vehicle’s audio system.
When the rear seat passengers play a DVD,
connect an external device to the RSE AUX
connectors, etc., and listen to the audio
through the cordless headphones, the driver
and front seat passenger can still use the vehi-
cle's audio system to listen to the radio, a CD,
music stored on an MP3 player, etc.
Please also refer to the Quick Guide provided
with the RSE system for additional information.Electrical current - ignition keyThe RSE system can be activated with the igni-
tion in mode I or II. or when the engine is
running. While the engine is being started, a
film or music that is currently being played will
pause momentarily and resume playing when
the engine has started.
When the RSE system has been used once
when the ignition is switched off, it will be then
be blocked for further use. RSE can be restar-
ted by putting the ignition in mode I.
NOTE
Using RSE for more than approximately
10 minutes with the engine switched off may
drain the vehicle’s battery and make it diffi-
cult or impossible to start the engine.
If this occurs, a message will be displayed
on the RSE system’s screens.MusicListening to a music CD1. Open the cover on the armrest between the
front seats and insert a CD into the RSE
player’s slot with the disc’s label facing for-
ward (away from the buttons).

157 Active chassis (Four C)–option
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.

04 Comfort and driving pleasureCollision warning with Auto-brake (option)
04160
IntroductionCollision 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:1. Collision warningThe driver is warned of the imminent risk of a
collision.2. Brake supportThis helps the driver brake efficiently in a criti-
cal situation.3. Auto-brakeThis function brakes the vehicle automatically
if a collision cannot be avoided.
WARNING
The auto-brake function connot 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

Function overview
Visual warning signal, collision riskRadar sensorCamera
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 connot 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.OperationSome settings are controlled from the center
console via a menu system. For information on
how the menu system is used, see page 120.

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

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 173.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 120 for more information on the menu
system.

04 Comfort and driving pleasureCollision warning with Auto-brake (option)

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 169.
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 161. 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 176), and Lane Departure Warning (see
page 178).
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 actionsIf 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.
Cause
Action
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.

04 Comfort and driving pleasureAdaptive Cruise Control–ACC (option)
04166
IntroductionAdaptive Cruise Control (ACC) is an optional
system designed to assist the driver by main-
taining a set speed or a set distance 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.
WARNING
•
Do not use the adaptive cruise control
system in demanding driving conditions
such as city traffic, winding roads, at
intersections, on slippery surfaces, in
poor visibility, heavy rain, etc.
•
Maintenance of cruise control compo-
nents must only be performed by an
authorized Volvo workshop.
WARNING
•
Adaptive cruise control cannot cover all
driving situations and traffic, weather
and road conditions. The Function sec-
tion provides information about limita-
tions that the driver must be aware of
before using the adaptive cruise con-
trol.
•
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.
Function
G021412
Function overview
Warning light, braking by driver requiredControlsRadar sensor in front grille
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 (expressed as a time inter-
val. For example, you can choose to
remain approximately 2 seconds behind
the vehicle ahead).

04 Comfort and driving pleasure
Adaptive Cruise Control–ACC (option)
04``167
WARNING
•
Adaptive cruise control is not a collision
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 slow moving or stationary vehicles.
The distance to the vehicle ahead (in the same
lane) is measured by a radar sensor. Your vehi-
cle's speed is regulated by acceleration 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 adaptive cruise control system is designed
to follow the vehicle ahead of you in the same
lane, at a set time interval.
If the radar sensor has not detected a vehicle
ahead, the system will then attempt to maintain
the set speed. This is also the case if the speedof the vehicle ahead exceeds the speed that
you have set.
The adaptive cruise control system is designed
to smoothly regulate speed. However, the
driver must apply the brakes in situations that
require immediate braking. This applies when
there are great differences in speed between
vehicles, or if the vehicle ahead brakes sud-
denly.
WARNING
Due to limitations in the radar sensor, brak-
ing may occur unexpectedly or not at all,
see page 169.Adaptive cruise control can only be activated
at speeds above 20mph (30 km/h). If speed
falls below 20 mph (30 km/h) or if engine speed
(rpm) becomes too low, adaptive cruise control
disengages and will no longer modulate the
brakes. In situations when adaptive cruise con-
trol cannot be activated
Cruise Control
Unavailable
is shown in the display, see
page 171.
WARNING
When adaptive cruise control disengages,
the brakes will not be modulated automati-
cally. The driver must assume full control
over the vehicle.Warning light-driver braking requiredAdaptive cruise control has a braking capacity
that is equivalent to approximately 30% of the
vehicle's total braking capacity. In situations
requiring more brake force than ACC can pro-
vide, if the driver does not apply the brakes, an
audible signal will sound and a red warning
light will illuminate 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.
WARNING
Cruise control only warns of vehicles
detected by the radar sensor, see
page 169. In some cases there may be no
warning or the warning may be delayed. The
driver should always apply the brakes when
necessary.
