Adaptive cruise control*
04
154* Option/accessory, for more information, see Introduction.
General information on ACC
The adaptive cruise control (ACC – Adaptive
Cruise Control) helps the driver maintain a safe
distance from the vehicle ahead. An adaptive
cruise control provides a more relaxing driving
experience on long journeys 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 Warning (see page 165)
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.
Read the whole of this section for informa-
tion on the limitations of the adaptive cruise
control. The driver must be familiar with this
information 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 gearboxCars with automatic gearbox have enhanced
functionality with the adaptive cruise control's
Queue Assistant, see page 159.

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 the Adap-
tive cruise control.
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 adaptive cruise control aims to control the
speed in a smooth way. In situations that
demand sudden braking the driver must brake
himself/herself. This applies with large differ-
ences 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 160.
The adaptive cruise control can be activated to
follow another vehicle at speeds from
30 km/h
2 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 173) 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. It may have difficultly 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 atten-
tive and ready to slow down.
2Queue Assistant (in cars with automatic gearbox) can operate in the range of 0-200 km/h, see page 159.

Changing the speedTo change the stored speed:
•Adjust with short presses on or -
every press gives +/- 5 km/h. The last
presses made are stored in the memory.
If speed is increased using the accelerator
pedal prior to pressing the
/ button,
then it is the car's current speed when the
button is pressed that is stored in the
cruise control.
•In active mode the button has the same
function as
but results in a lower
increase in speed: + 1 km/h.
NOTE
If any of the Cruise Control buttons are held
down for more than approx. 1 minute, it is
blocked and disabled. To be able to reacti-
vate Cruise Control, the car must be stop-
ped and the engine restarted.
In certain situations, cruise control cannot
be activated. Then the display shows
Cruise control Unavailable, see
page 162.
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 interval. One line corre-
sponds to approx. 1 second
to the vehicle in front, 5 lines
approx. 3 seconds.
To set/change the time interval:
•Increase or decrease with the steering
wheel keypad's thumbwheel (or the but-
tons
/ 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 small intervals only allow 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 Warning is activated, see page 165.
NOTE
Only use the time intervals permitted by
local traffic regulations.
If Cruise Control does not appear to react
when activated, this may be because the
time distance to the car in front is preventing
an increase in speed.
The higher the speed the longer the calcu-
lated distance in metres for a given time
interval.
Temporary deactivation - standby modeTo temporarily disengage Cruise control and
set it in standby mode:
•Press the steering wheel button .

•Press the steering wheel button .
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 minute6
•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.
Automatic standby modeThe Adaptive cruise control is dependent on
other systems, e.g.. DSTC (see page 146). Ifany of these systems stop working then cruise
control is automatically deactivated.
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/h7
•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 .
Overtaking another vehicleWhen the car is following another vehicle and
the driver indicates an imminent overtake with
the direction indicator
8, the Cruise control
helps to briefly accelerate the car towards the
vehicle in front.
The function is active at speeds
above 70 km/h.
WARNING
Be aware that this function can be activated
in more situations other than during over-
taking, e.g. when a direction indicator is
used to indicate a change of lane or exit to
another road - the car will then accelerate
briefly.

With a further short press the cruise control is
deactivated. The set speed is cleared and can-
not be resumed with the
button.
Queue Assistant
In cars with automatic gearbox Adaptive cruise
control is supplemented with the Queue Assis-
tant function (also referred to as "Queue
Assist").
Queue Assistant has the following functions:
•Extended speed range - also below 30 km/
h and at standstill
•Change of target
•Automatic braking ceases when stationary
•Automatic activation parking brake.
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.
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 automatic gearbox the cruise control can
follow another vehicle within the range of
0-200 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 with automatic
braking. The driver must then re-activate the
cruise control in one of the following ways:
•Press the steering wheel button .
or
•Depress the accelerator pedal.
> The cruise control will then resume follow-
ing the vehicle in front.
NOTE
Queue Assist can hold the car stationary for
a maximum of 4 minutes - then the parking
brake is applied and Cruise Control is dis-
engaged.
•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 5 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 5 km/h and the
vehicle in front turns off so the cruise con-
trol no longer has a vehicle to follow.
Termination of automatic braking at a
standstill
In certain situations Queue Assist automati-
cally interrupts braking when stationary. This
means that the brakes are released and the car
may start to roll - the driver must therefore
intervene and brake the car himself/herself in
order to maintain its position.Queue Assist releases the foot brake and sets
cruise control in standby mode in the following
situations:
•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 Queue Assist applies the
parking brake in order to keep the car station-
ary.
This takes place if:
•the driver opens the door or takes off his/
her seatbelt
•DSTC is changed from Normal to Sport
mode
•Queue Assist has held the car stationary
for more than 4 minutes
•the engine is switched off
•the brakes have overheated.
The radar sensor and its limitations
The radar sensor is used - apart from by Adap-
tive cruise control - by the following functions
as well:
•Collision Warning with Auto Brake, see
page 173
•Distance Warning, see page 165.
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.
