Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.147
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
•engine speed (rpm) is too low or too high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Special ACC functionsThe following ACC functions are linked to your
vehicle's automatic transmission.
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
20 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
20 mph (30 km/h), although ACC will also
help maintain the set time interval to the
vehicle 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 117 and press
.
Automatic standby mode when ACC
changes target vehicles
If the vehicle ahead turns suddenly, there may be
a stationary vehicle ahead

148* Option/accessory, for more information, see Introduction.
The following only applies at speeds below
approximately 20 mph (30 km/h):
If ACC changes target vehicles (the vehicle that
the radar sensor has detected) from a moving
vehicle to a stationary one, the system will
apply the brakes in your vehicle.
WARNING
At speeds above 20 mph (30 km/h), ACC
will not react to a stationary vehicle and
apply the brakes but will instead accelerate
to the previously set speed. The driver must
actively apply the brakes to stop the vehicle.
ACC disengages and goes into standby mode
if:
•Your vehicle's speed goes below 10 mph
(15 km/h) and ACC cannot determine if the
target object is a stationary vehicle or some
other type of object such as e.g., a speed
bump.
•Your vehicle's speed goes below 10 mph
(15 km/h) and the vehicle ahead turns so
that ACC no longer has a target vehicle to
follow.
No automatic braking when at a
standstill
In certain situations, ACC will no longer apply
the brakes and go into standby mode while thevehicle is not moving. This means that the
driver will have to apply the brakes.
This happens if:
•The driver presses the brake pedal
•The parking brake is activated
•The gear selected is moved to P,N or R
•The driver presses the button to put
ACC in standby mode
The parking brake is applied
automatically
In certain situations, ACC will apply the parking
brake in order to continue keeping the vehicle
at a standstill.
This happens if:
•The driver opens the door or takes off
his/her seat belt
•DSTC is put in Sport mode (see page 138)
•ACC has kept the vehicle at a standstill for
more than 2 minutes
•The engine has been switched off
•The brakes have overheated
Turning ACC off completely
Pressing 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 153) and Collision Warning with Full
Auto-brake and Pedestrian Detection (see
page 162). 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.

Situations where ACC may not function
optimally
WARNING
•The radar sensor has a limited field of
vision. In some situations it may detect
a vehicle later than expected or not
detect other vehicles at all.
•If ACC is not functioning properly,
cruise control will also be disabled.
Radar sensor's field of vision (dark gray)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters the
lane between your vehicle and the target
vehicle.
Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.
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 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.

Press Brake To hold + an
audible signalThe vehicle is at a standstill and ACC will release the brakes before the parking brake engages to keep
the vehicle stopped but a problem with the parking brake means that the vehicle may begin to roll.
The driver will have to apply the brakes. The message will remain in the display and the audible signal
will continue until the driver applies the brakes or presses the accelerator pedal.
–Below 20 mph Only follow-
ingThis is displayed if you try to activate ACC at speeds below 20 mph (30 km/h) without a vehicle ahead
within range (approx. 100 ft/30 meters).

04 Comfort and driving pleasure
Distance Alert*
04

* Option/accessory, for more information, see Introduction.153 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 20 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 light
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 active mode.
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
Car settingsDistance alertOn/Off.
Setting a time interval
Controls and display
Time interval: Increase/decrease
Time interval: On, while it is being set
Time interval: On, after it has been set
Turn the thumb wheel (4) up to increase the
time interval or down to decrease it.

Distance Alert*
04
154* 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 145.
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 148 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.

Collision warning with Full Auto-brake and Pedestrian Detection*
04
164* Option/accessory, for more information, see Introduction.
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 153.
NOTE
•When Adaptive Cruise Control is used,
the warning light and signal will be used
by that function, even if the warnings
provided by Collision Warning 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 pressing MY CAR on the center
console control panel and going to Settings
Car settingsCollision warning.
Limitations
Strong 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.
Slippery driving conditions increase braking
distance, which can reduce the system's
capacity to avoid a collision. In these condi-
tions, the ABS and DSTC systems provide the
best possible braking effect while helping to
maintain stability.
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.
WARNING
•In certain situations, the system cannot
provide warnings or warnings may be
delayed if traffic conditions or other
external factors make it impossible for
the radar sensor or camera to detect a
pedestrian or a 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 pedestrians and provides warnings
and braking effect most effectively at
speeds up to 30 mph (50 km/h). For sta-
tionary or slow-moving vehicles, the
system functions best if your vehicle’s
speed is below 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 148.
