Adaptive cruise control*
04

* Option/accessory, for more information, see Introduction.171 General information on ACC
The adaptive cruise control (ACC – Adaptive
Cruise Control) helps the driver maintain a safe
distance from the vehicle ahead. It provides a
more relaxing driving experience on long jour-
neys on motorways and long straight main
roads in smooth traffic flows.
The driver sets the desired speed and time
interval to the car in front. When the radar
detector detects a slower vehicle in front of the
car, the speed is automatically adapted to that.
When the road is clear again the car returns to
the selected speed.
If the adaptive cruise control is switched off or
set to the standby mode and the car comes too
close to a vehicle in front, then the driver is
warned by Distance Alert (see page 181) about
the short distance.WARNING
The driver must always be observant with
regard to the traffic conditions and intervene
when the adaptive cruise control is not
maintaining a suitable speed or suitable dis-
tance.
The adaptive cruise control cannot handle
all traffic, weather and road conditions.
The Function section and onwards informs
about limitations of which the driver should
be aware before using the adaptive cruise
control.
The driver always bears responsibility for
maintaining the correct distance and speed,
even when the adaptive cruise control is
being used.
IMPORTANT
Maintenance of adaptive cruise control
components must only be performed at a
workshop - an authorised Volvo workshop
is recommended.
Automatic gearboxThe adaptive cruise control has enhanced
functionality (Queue Assist) on cars with auto-
matic gearbox, see page 175.

172* Option/accessory, for more information, see Introduction.
WARNING
Adaptive cruise control is not a collision
avoidance system. The driver must inter-
vene if the system does not detect a vehicle
in front.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcycles.
Nor for oncoming, slow or stationary vehi-
cles and objects.
Do not use the adaptive cruise control, for
example, in city traffic, in dense traffic, at
junctions, on slippery surfaces, with a lot of
water or slush on the road, in heavy rain/
snow, in poor visibility, on winding roads or
on slip roads.
The distance to the vehicle ahead is mainly
measured by a radar sensor. Cruise control
regulates the speed with acceleration and
braking. It is normal for the brakes to emit a low
sound when they are being used by cruise con-
trol.
WARNING
The brake pedal moves when the cruise
control brakes. Do not rest your foot under
the brake pedal as it could become trapped.
The adaptive cruise control aims to follow the
vehicle ahead in the same lane at a time interval
set by the driver. If the radar sensor cannot see
any vehicle in front then the car will instead
maintain the cruise control's set speed. This
also happens if the speed of the vehicle in front
exceeds the cruise control's set speed.
The cruise control aims to control the speed in
a smooth way. In situations that demand sud-
den braking the driver must brake himself/her-
self. This applies with large differences in
speed, or if the vehicle in front brakes heavily.
Due to limitations in the radar sensor, braking
may come unexpectedly or not at all, see
page 177.
The adaptive cruise control can be activated to
follow another vehicle at speeds from
30 km/h
1 up to 200 km/h. If the speed falls
below 30 km/h or if the engine speed becomes
too low, the cruise control is set in standby
mode at which automatic braking ceases - the
driver must then take over himself/herself to
maintain a safe distance to the vehicle ahead.
Warning lamp - braking by driver
required
Adaptive cruise control has a braking capacity
that is equivalent to more than 40% of the car's
braking capacity.If the car needs to be braked more heavily than
cruise control capacity and the driver does not
brake, then the cruise control uses the collision
warning system's warning lamp and warning
sound (see page 189) to alert the driver that
immediate intervention is required.
NOTE
The warning lamp may be difficult to notice
in strong sunlight or when sunglasses are
being worn.
WARNING
Cruise control only warns of vehicles
detected by the radar sensor. Consequently
there may be no warning or it may be sub-
ject to a delay. Do not wait for a warning but
brake when it is necessary.
Steep roads and/or heavy loadBear in mind that the adaptive cruise control is
primarily intended for use when driving on level
road surfaces. The cruise control may have dif-
ficultly in keeping the correct distance from the
vehicle ahead when driving on steep roads,
with a heavy load or with a trailer - in which
case, be extra attentive and ready to slow
down.
1Cars with automatic gearbox ("Queue Assist") can operate in the range of 0-200 km/h, see page 175.

174* Option/accessory, for more information, see Introduction.
NOTE
If any cruise control button is held
depressed for more than approx. 1 minute
then cruise control is disengaged. The
engine must be switched off in order to reset
cruise control.
In certain situations, cruise control cannot
be activated. Then the display shows
Cruise control Unavailable, see
page 179.
Set time intervalDifferent time intervals to the
vehicle in front can be
selected and shown in the
display as 1-5 horizontal lines
- the more lines the longer the
time distance. One line corre-
sponds to approximately
1 second, 5 lines approximately 2.5 seconds.
The time interval is increased or decreased
with the steering wheel keypad's thumbwheel
(or the buttons
/ for cars without Speed
limiter).
At low speed, when the distances are short, the
adaptive cruise control increases the time
interval slightly.The adaptive cruise control allows the time
interval to vary noticeably in certain situations
in order to allow the car to follow the vehicle in
front smoothly and comfortably.
Note that a short time interval only allows the
driver a short time to react and take action if
any unforeseen traffic problem should arise.
The number of lines for the
selected time interval is
shown during the setting itself
and for several seconds after-
wards. Then a smaller scale
version of the symbol is
shown to the right of the dis-
play. The same symbol is also shown when
Distance Alert is activated, see page 181.
NOTE
Only use the time interval that is allowed in
accordance with local traffic regulations.
If cruise control does not seem to react to
activation the reason may be that the time
interval to the closest vehicle prevents an
increase in speed.
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
Temporary deactivation - standby mode
Press the steering wheel button to tempo-
rarily disengage the cruise control and set it in
standby mode - set speed is shown in brackets
in the display, e.g.
(100).
Keypad without Speed limiter
Press the steering wheel button to tempo-
rarily disengage cruise control and set it in
standby mode.
Standby mode due to driver interventionCruise control is temporarily disengaged and
set in standby mode if:
•the foot brake is used
•the clutch pedal is depressed for longer
than 1 minute4
•the gear selector is moved to N position
(automatic gearbox)
•the driver maintains a speed higher than
the set speed for longer than 1 minute
The driver must then regulate the speed.
A temporary increase in speed with the accel-
erator pedal, e.g. during overtaking, does not
affect the cruise control setting - the car returns
to the last stored speed when the accelerator
pedal is released.
4Disengaging and selecting a higher or lower gear does not involve standby mode.

Automatic standby modeAdaptive cruise control is dependent on other
systems e.g. stability and traction control
(DSTC). If any of these systems stop working
then cruise control is automatically deacti-
vated.
In the event of automatic deactivation a signal
will sound and the message
Cruise control
Cancelled is shown in the display. The driver
must then intervene and adapt the speed and
distance to the vehicle ahead.
An automatic deactivation can be due to:
•engine speed is too low/high
•speed falls below 30 km/h5
•wheels lose traction
•brake temperature is high
•the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).
Resume set speedCruise control in standby mode is re-activated
with one press on the steering wheel button
- the speed is then set to the last stored
speed.
NOTE
A significant increase in speed may arise
after the speed has been resumed with .
DeactivateThe cruise control is switched off with the
steering wheel button
. The set speed is
cleared and cannot be resumed with the
button.
Keypad without Speed limiterThe cruise control is switched off with the
steering wheel button
in standby mode or
with one long press in active mode. The set
speed is cleared and cannot be resumed with
the
button.
Queue Assist ACC and automatic
gearbox*
In cars with automatic gearbox the adaptive
cruise control has more functions than in cars
with manual gearbox.
Note that the lowest programmable speed for
the cruise control is 30 km/h - even though the
cruise control is capable of following another
vehicle down to a standstill, a lower speed
cannot be selected.The following functions are available:
Extended speed range
NOTE
In order to activate the cruise control the
driver's door must be closed and the driver
must be wearing the seatbelt.
•With the automatic gearbox the cruise con-
trol can follow another vehicle within the
range of 0-200 km/h - right down to sta-
tionary and up to 200 km/h.
NOTE
Activation of the cruise control below
30 km/h requires a vehicle in front within a
reasonable distance.
For shorter stops in connection with inching in
slow traffic or at traffic lights driving is auto-
matically resumed if the stops do not exceed
about 3 seconds - if it takes longer before the
car in front starts moving again then the cruise
control is set in standby mode. The driver must
then re-activate the cruise control in one of the
following ways:
•Press the steering wheel button .
5Does not apply to cars with automatic gearbox ("Queue Assist") - they manage right down to stationary.

or
•Press the accelerator pedal and accelerate
up to at least about 4 km/h (normal walking
pace).
The cruise control will then resume following
the vehicle in front.
NOTE
The cruise control can hold the car station-
ary for a maximum of 2 minutes - then the
parking brake is applied and the cruise con-
trol is disengaged.
•The driver has to release the parking
brake before the cruise control can be
reactivated.
Change of target
If the target vehicle in front suddenly turns then
there may be stationary traffic in front.
When the cruise control is following another
vehicle at speeds below 30 km/h and changes
target from a moving to a stationary vehicle, the
cruise control will slow down for the stationary
vehicle.
WARNING
When the cruise control is following another
vehicle at speeds in excess of 30 km/h and
the target is changed from a moving vehicle
to a stationary vehicle, the cruise control will
ignore the stationary vehicle and instead
select the stored speed.
•The driver must intervene him/herself
and brake.
Automatic standby mode with change of
target
Cruise control is disengaged and set in
standby mode:
•when the speed is below 15 km/h and
cruise control is not sure whether the target
object is a stationary vehicle or some other
object, e.g. a speed bump.
•when the speed is below 15 km/h and the
vehicle in front turns off so the cruise con-
trol no longer has a vehicle to follow.
Automatic braking ceases when
stationary
In certain situations the cruise control inter-
rupts braking when stationary. This means that
the foot brake is released and the driver must
brake himself/herself.
Cruise control releases the foot brake and is
set in standby mode when:
•the driver puts his/her foot on the brake
pedal
•the parking brake is applied
•the gear selector is moved to P, N or R
position
•the driver sets the cruise control in standby
mode.
Automatic activation parking brakeIn some situations the cruise control applies
the parking brake in order to keep a stationary
car remaining stationary.
This takes place if:
•the driver opens the door or takes off his/
her seatbelt
•DSTC is changed from Normal to Sport
mode
•cruise control has held the car stationary
for more than 2 minutes
•the engine is switched off
•the brakes have overheated.

* Option/accessory, for more information, see Introduction.177 The radar sensor and its limitations
Apart from the adaptive cruise control, the
radar sensor is also used by the Collision
Warning with Auto Brake function (see
page 188) and the Distance Alert function (see
page 181). The function of the radar sensor is
to detect cars or larger vehicles in the same
direction, in the same lane.
Modification of the radar sensor could result in
it being illegal to use.
WARNING
The driver must always be observant with
regard to the traffic conditions and intervene
when the adaptive cruise control is not
maintaining a suitable speed or suitable dis-
tance.
The adaptive cruise control cannot handle
all traffic, weather and road conditions.
The Function section and onwards informs
about limitations of which the driver should
be aware before using the adaptive cruise
control.
The driver always bears responsibility for
maintaining the correct distance and speed,
even when the adaptive cruise control is
being used.
WARNING
Accessories or other objects such as auxil-
iary lamps must not be installed in front of
the grille.
WARNING
Adaptive cruise control is not a collision
avoidance system. The driver must inter-
vene if the system does not detect a vehicle
in front.
The adaptive cruise control does not brake
for humans or animals, and not for small
vehicles such as bicycles and motorcycles.
Nor for oncoming, slow or stationary vehi-
cles and objects.
Do not use the adaptive cruise control, for
example, in city traffic, in dense traffic, at
junctions, on slippery surfaces, with a lot of
water or slush on the road, in heavy rain/
snow, in poor visibility, on winding roads or
on slip roads.
The capacity of the radar sensor to detect vehi-
cles in front is reduced significantly:
•if the radar sensor becomes blocked and
cannot detect other vehicles e.g. in heavy
rain or slush, or if other objects have col-
lected in front of the radar sensor.
NOTE
Keep the surface in front of the radar sensor
clean.
•if the speed of vehicles in front is signifi-
cantly different from your own speed.
Examples where the cruise control does
not work optimally
The radar sensor has a limited field of vision. In
some situations another vehicle is not
detected, or the detection is made later than
expected.

The ACC cannot see small vehicles (Dark triangle:
ACC field of vision).
Sometimes the radar sensor is late at
detecting vehicles at close distances, e.g.
a vehicle that drives in between the car and
vehicles in front.
Small vehicles, such as motorcycles, or
vehicles not driving in the centre of the lane
can remain undetected.
In bends the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.
Fault tracing and action
If the display shows the message Radar
blocked See manual this means that the
radar signals from the radar sensor are blocked
and that vehicles in front of the car could not
be detected.
In turn this means that the Adaptive Cruise
Control, Distance Alert and Collision Warning
with Auto Brake functions are not operating
either.The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The radar surface in the grille is dirty or covered with ice or snow.Clean the radar surface in the grille from dirt, ice and snow.
Heavy rain or snow blocking the radar signals.No action. Sometimes the radar does not work during heavy rain or
snowfall.
