Adaptive Cruise Control (ACC)*
04
156* Option/accessory, for more information, see Introduction.
When the symbol on the
left side of the display
changes to
, the radar sen-
sor has detected another
vehicle ahead. The distance
to a vehicle ahead is only
regulated when this symbol (
) is illumi-
nated.
Changing the set speedAfter a speed has been set, it can be increased
or decreased by using the
or buttons.
Each time one of these buttons is pressed, the
vehicle's speed changes by 5 mph
(approximately 8 km/h).
When the system is in active mode, the
but-
ton has the same function as
, but results in
a smaller increase in speed.
NOTE
•If one of the Adaptive Cruise Control
buttons is pressed for more than
approximately one minute, ACC will be
deactivated. The engine must then be
switched off and restarted to reset ACC.
•In some situations Adaptive Cruise
Control cannot be put in active mode.
Cruise control Unavailable is shown
in the display, see page 161.
Setting a time intervalThe set time interval to vehicles ahead can be
increased by pressing
and decreased by
pressing
. The current time interval is shown
briefly in the display following adjustment.
Different time intervals can be
selected and are shown in the
display as 1–5 horizontal bars.
The greater the number of
bars, the longer the time inter-
val. One bar represents a time
interval of approximately
1 second; 5 bars is approximately
2.5 seconds. At low speeds, when the distance
to the vehicle ahead is short, ACC increases
the time interval slightly. In order to follow the
vehicle ahead as smoothly as possible, ACC
allows the time interval to vary considerably in
certain situations.
WARNING
•Only use a time interval that is suitable
in current traffic conditions.
•A short time interval gives the driver lim-
ited reaction time if an unexpected sit-
uation occurs in traffic.
The number of bars indicating the selected
time interval are shown while the setting is
being made and for several seconds afterward.
A smaller version of the symbol is then shown
to the right in the display. The same symbol is
also displayed when Distance Alert is in active
mode, see page 163 .
Standby mode (temporary deactivation)
Press to temporarily deactivate cruise con-
trol (put it in standby mode). The set speed, for
example 55 mph, is then shown in parenthe-
ses.
The previously set speed and time interval are
resumed by pressing
.
WARNING
There may be a significant increase in speed
after the button has been pressed.
When ACC is in active mode, the vehicle’s
speed increases by approximately 1 mph
(1 km/h) each additional time
is pressed.

Standby mode due to action by the driverACC is temporarily deactivated and put in
standby mode:
•when the brakes are applied
•if the driver's seat belt is taken off
•If the driver's door is opened
•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 wheels lose traction
•brake temperature is high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Queue Assist*The following functions are linked to your vehi-
cle's automatic transmission and comprise the
Queue Assist feature.
Please note that the lowest speed that can be
set is 18 mph (30 km/h), although ACC can
maintain a set speed/distance to a vehicle
ahead down to a standstill. Queue Assist con-
sists of the following features:
Enhanced speed intervalYour vehicle can maintain the set time interval
to the vehicle ahead at any permissible speed,
including a complete stop.
In order to activate ACC at speeds below
18 mph (30 km/h):
•The vehicle ahead must be within a rea-
sonable distance (not farther away than
approx. 100 ft/30 meters)
•The lowest speed that can be selected is
18 mph (30 km/h), although ACC will also
help maintain the set time interval to thevehicle ahead at lower speeds, including a
complete stop.
During short stops (less than approximately
3 seconds) in slow-moving traffic, your vehicle
will begin moving again automatically as soon
as the vehicle ahead begins to move.
If it takes more than 3 seconds for the vehicle
ahead to begin moving, ACC will be automati-
cally go into standby mode.
The driver will then have to reactivate ACC in
one of the following ways:
•By pressing
•By accelerating up to at least 3 mph
(4 km/h)
Your vehicle will then resume following the
vehicle ahead at the set time interval.
NOTE
ACC can remain active and keep your vehi-
cle at a standstill for up to 2 minutes. After
2 minutes have elapsed, the parking brake
will be engaged and ACC will go into
standby mode.
To reactivate ACC, the driver must release
the parking brake (see page 122) and press
.

In curves, the radar sensor may detect the
wrong vehicle or lose sight of the target
vehicle.
WARNING
•Adaptive Cruise Control cannot cover
all driving situations and traffic, weather
and road conditions. The "Function"
section provides information about lim-
itations that the driver must be aware of
before using this feature.
•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 to the vehicle ahead.
•Maintenance of ACC components may
only be performed by a trained and
qualified Volvo technician.
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 and Pedestrian
Detection 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.

* Option/accessory, for more information, see Introduction.163 Introduction
Distance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Distance Alert is active at speeds above
approximately 18 mph (30 km/h). Time interval
information is only given for a vehicle that is
driving ahead of your vehicle in the same direc-
tion. No information is provided for vehicles
driving toward you, moving very slowly, or at a
standstill.
Amber warning light1.
An amber warning light in the windshield glows
steadily if your vehicle is closer to the one
ahead than the set time interval.
NOTE
Distance Alert only monitors distance to the
vehicle ahead while Adaptive Cruise Control
is in standby mode or off.
WARNING
Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.
Operation
Press the button in the center instrument panel
to switch this function on or off. The indicator
light in the button illuminates when the function
is on.Depending on the optional equipment
selected, there may not be room for a Distance
Alert button in the center console. In this case,
the function is controlled through the menu
system. Press MY CAR and go to Settings

164* Option/accessory, for more information, see Introduction.
Five different time intervals
can be selected and are
shown in the display as 1–5
horizontal bars. The greater
the number of bars, the longer
the time interval. One bar rep-
resents approximately
1 second to the vehicle ahead; 5 bars is
approximately 2.5 seconds.
The number of bars indicating
the selected time interval are
shown while the setting is
being made and for several
seconds afterward. A smaller
version of the symbol is then
shown to the right in the dis-
play. The same symbol is displayed when
Adaptive Cruise Control (ACC) is activated.
NOTE
•The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
•The set time interval is also used by
Adaptive Cruise Control, see page 155.
WARNING
Only use a time interval that is suitable in
current traffic conditions.
Limitations
Distance Alert uses the same radar sensor
used by Adaptive Cruise Control and the Col-
lision Warning system. See page 158 for more
information on the radar sensor’s limitations.
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
•Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
•The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all.
