ing gently for a short period while the vehicle is
moving.Emergency Brake AssistanceEBA is designed to provide full brake effect
immediately in the event of sudden, hard brak-
ing. The system is activated by the speed with
which the brake pedal is depressed.
When the EBA system is activated, the brake
pedal will go down and pressure in the brake
system immediately increases to the maximum
level. Maintain full pressure on the brake pedal
in order to utilize the system completely. EBA
is automatically deactivated when the brake
pedal is released.
NOTE
•
When the EBA system is activated, the
brake pedal will go down and pressure
in the brake system immediately increa-
ses to the maximum level. You must
maintain full pressure on the brake
pedal in order to utilize the system com-
pletely. There will be no braking effect if
the pedal is released. EBA is automati-
cally deactivated when the brake pedal
is released.
•
When the vehicle has been parked for
some time, the brake pedal may sink
more than usual when the engine is
started. This is normal and the pedal will
return to its usual position when it is
released.

Ventilated front seats (option)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-
midification 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.
•

IntroductionThe 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-

04 Comfort and driving pleasureStability system
04154
IntroductionThe 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.Operation

Messages in the information displayDSTC Temporarily OFF
– system function
has been temporarily reduced due to high
brake disc temperature. The function is acti-
vated automatically when the brakes have
cooled.
DSTC Service required
– the system has
been disabled due to a fault. If this occurs:
1. Stop the vehicle in a safe place and turn off
the engine.
2. Restart the engine.
If the message remains when the engine is
restarted, drive to an authorized Volvo work-
shop to have the system inspected.

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.

04 Comfort and driving pleasureActive chassis system–Four C
04156
Active chassis (Four C)–optionActive 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
G021410
Chassis settingsUse 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
(option)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
