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.
Activate or deactivate this function in Climate
settings

NOTE
•The air quality sensor should always be
engaged in order to obtain the best air
in the passenger compartment.
•Recirculation is limited in cold weather
to avoid fogging.
•If the insides of the windows start fog-
ging, disengage the air quality sensor.
Use the defroster function to increase
airflow to the front, side, and rear win-
dows.

Stability system
04
148* Option/accessory, for more information, see Introduction.
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.
Trailer Stability Assist – TSA*Trailer Stability Assist helps stabilize a vehicle
that is towing a trailer when the vehicle and
trailer have begun to sway. See page 281 for
more information.
This system is automatically deactivated if the
driver selects Sport mode.
Operation
Sport modeThe stability system is always activated and
cannot be switched off.
However, the driver can select Sport mode,
which offers more active driving characteris-
tics. In this mode, the engine management sys-
tem monitors movement of the accelerator
pedal and steering wheel for sportier driving byallowing more lateral movement of the rear
wheels before DSTC is activated.
Under certain circumstances, such as when
driving with snow chains, or driving in deep
snow or loose sand, it may be advisable to
temporarily use Sport mode for maximum
tractive force.
If the driver releases pressure on the acceler-
ator pedal, DSTC will also activate to help sta-
bilize the vehicle.
To switch to Sport mode:
1.
Press the My Car button in the center con-
sole control panel and select My XC70
DSTC in the menu.
2. Unselect the symbol and leave the menu
by pressing EXIT.
>
This puts DSTC in Sport mode.
Sport mode remains active until the driver
switches it off in the menu or until the engine is
switched off. DSTC will return to normal mode
when the engine is restarted.

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.

Active chassis system–Four C*
04
150* 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.
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
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 MY CAR
Car settingsSteering wheel force.Select
Low, Medium or High. For a descrip-
tion of the menu system, see page 131.
NOTE
This steering force level menu function can-
not be accessed when the vehicle is in
motion.
