Electric parking brake
An electric parking brake has the same func-
tion as a manual parking brake.
NOTE
•A faint sound from the parking brake's
electric motor can be heard when the
parking brake is being applied. This
sound can also be heard during the
automatic function check of the parking
brake.
•The brake pedal will move slightly when
the electric parking brake is applied or
released.
Low battery voltageIf the battery voltage is too low, the parking
brake cannot be applied or released. Connect
an auxiliary battery if the battery voltage is too
low, see page 109.
Applying the electric parking brake
Parking brake control
1. Press firmly on the brake pedal.
2. Push the control.
3. Release the brake pedal and ensure that
the vehicle is at a standstill.
4. When the vehicle is parked, the gear selec-
tor must be in position P.
The
symbol in the instrument panel
flashes while the parking bake is being applied,
and glows steadily when the parking brake has
been fully applied.
NOTE
•In an emergency the parking brake can
be applied when the vehicle is moving
by holding in the control. Braking will be
interrupted when the accelerator pedal
is depressed or the control is released.
•An audible signal will sound during this
procedure if the vehicle is moving at
speeds above 6 mph (10 km/h).
Parking on a hill
•If the vehicle is pointing uphill, turn the front
wheels so that they point away from the
curb.
•If the vehicle is pointing downhill, turn the
front wheels so that they point toward the
curb.
The parking brake should also be applied.

Parking brake not applied – A fault is pre-
venting the parking brake from being applied.
Try to apply and release. Contact a Volvo work-
shop if the message remains.
Parking brake Service required – A fault has
occurred. Contact a Volvo workshop if the fault
remains.
WARNING
If the vehicle must be parked before the fault
has been corrected, always put the gear
selector in P and turn the wheels so that
they point away from the curb if the vehicle
is pointing uphill or toward the curb if it is
pointing downhill.

channels will be displayed as 93.9 – 2
WNYC, 93.9 - 3 WNYC, etc.
•Reception coverage area: Due to current
IBOC transmitter power limitations, the
reception coverage area in digital mode is
somewhat more limited than the station's
analogue coverage area. Please be aware
that as with any radio broadcast technol-
ogy, terrain, time of day, foliage level and
building location can have positive or neg-
ative effects on radio reception.
•Analogue to digital/digital to analogue
blending: Analogue to digital blending will
occur as the signal strength reaches a pre-
set threshold in the receiver. This will be
noticeable in fringe areas (areas with weak
reception) and is normal.
NOTE
There may be a noticeable difference in
sound quality when a change from analogue
to digital or digital to analogue occurs, such
as:
•Volume increase or decrease
•Equalizer settings, i.e., Bass/ Midrange/
Treble cut or boost
•Time alignment (Digital program mate-
rial in extreme cases can be as much as
8 seconds behind the analogue). This
will noticeable as a "stuttering" effect.
The above items are dependant on the
broadcaster's equipment settings and do
not indicate a fault in the vehicle's radio
receiver or antenna systems.
Switching HD on or offThe factory setting for HD radio is on. However,
when driving through areas with weak HD sig-
nals (fringe areas), you may experience that the
radio repeatedly switches between analogue/
digital and digital/analogue reception. If this
happens, it may be desirable to switch HD off.
To do so:
1. Be sure the audio system is switched on
and in AM or FM mode.
2.
Press MENU in the center console control
panel.3.
Press ENTER to turn HD off (the X will dis-
appear from the box on the display screen).
This will disable the radio's capability to receive
digital broadcasts but it will continue to func-
tion as a conventional (analogue) AM/FM
receiver. Please note that when HD is switched
off, it will not be possible to tune to sub-chan-
nels (see the following section for a more
detailed explanation of sub-channels).
Repeat steps 2 and 3 above to reactivate HD
(an X will appear in the box on the display
screen).
Sub-channels
Example of an HD Radio station with sub-channels
In many cases, a main HD Radio station (FM
wavebands only) will also have sub-channels
offering additional types of programming or
music.

Adaptive Cruise Control (ACC)*
04
166* Option/accessory, for more information, see Introduction.
Standby mode due to action by the driverACC is temporarily deactivated and put in
standby mode:
•when the brakes are applied
•if the gear selector is moved to N
•if the accelerator pedal is depressed for
more than 1 minute.
NOTE
If the accelerator pedal is only depressed for
a short time, such as when passing another
vehicle, ACC is deactivated temporarily and
is reactivated when the pedal is released.
Automatic standby modeAdaptive cruise control is linked to other sys-
tems such as the stability and traction control
system (DSTC). If this system is not functioning
properly, adaptive cruise control is automati-
cally deactivated and will go into standby
mode.
In the event of automatic deactivation, an audi-
ble signal will sound and the message
Cruise
control Cancelled is shown in the display.
The driver must then intervene and adapt the
vehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.
An automatic switch to standby mode may be
caused if:
•the vehicle's speed falls below 20 mph
(30 km/h)
•the wheels lose traction
•brake temperature is high
•engine speed (rpm) is too low or too high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Turning ACC off completely
A short press on in standby mode or a long
press in active mode turns ACC off completely.
The set speed and time interval are then
cleared from the system's memory and cannot
be resumed by pressing
.
The radar sensor and its limitations
In addition to being used by ACC, the radar
sensor is also used by Distance Alert (see
page 171) and Collision Warning with Auto-
brake (see page 174). This sensor is designed
to detect cars or larger vehicles driving in the
same direction as your vehicle, in the same
lane.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.
The radar sensor's capacity to detect vehicles
ahead is impeded:
•if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.
NOTE
Keep the area in front of the radar sensor
clean.
•if the speed of vehicles ahead is signifi-
cantly different from your own speed.

Adaptive Cruise Control (ACC)*
04
168* 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.
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.

CauseAction
Swirling water or snow from the surface of the road may interfere with
the radar signals.No action possible. A very wet or snow-covered road surface may affect
the function of the radar.
The surface of the radar is clean but the message remains in the display.Wait a short time. It may take several minutes for the radar to detect that
it is no longer obstructed.

Collision warning with Auto-brake*
04

* Option/accessory, for more information, see Introduction.175
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 or begun to steer around the
vehicle, 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. The
driver must apply the brakes for full braking
effect.
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.
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.
When the engine is switched on, the Collision
Warning setting that was being used when it
was switched off will be the default setting.
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 switched on.
The audible warning signal can be activated/
deactivated by selecting the alternative
Collision warning on or Collis'n warning

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

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 171.

Driver Alert System*
04

* Option/accessory, for more information, see Introduction.181 Operating DAC
Certain settings can be made from the menu
system controlled from the center instrument
panel.
The current system status can be checked on
the trip computer’s display by using the but-
tons on the left steering wheel lever.
Thumb wheel. Turn this wheel until Driver
Alert is displayed. The second line shows
the alternatives Off, Unavailable, or [-----
], i.e., the number of bars.
READ button. Confirms and erases a mes-
sage in the display.
Activating DACIn the center instrument panel, go to Car
settings and select Driver Alert on.
The function is activated when the
vehicle exceeds a speed of 40 mph
(65 km/h). The display will show level
markings of 1–5 bars, where a low
number of bars indicates erratic driving. A high
number of bars indicates stable driving.
If the vehicle is being driven erratically, the
driver will be alerted by an audible signal and
the message Driver Alert, Time for a break is
displayed. The warning will be repeated after a
short time if the driving pattern remains the
same.
WARNING
•An alert should be taken seriously since
it is sometimes difficult for a driver to
realize that he/she is fatigued.
•In the event of a warning or if the driver
feels fatigued, stop as soon as possible
in a safe place and rest.
