Adaptive cruise control*
04
* Option/accessory, for more information, see Introduction.175 General information on ACC
The adaptive cruise control (ACC – Adaptive
Cruise Control) helps the driver maintain a safe
distance from the vehicle ahead. The cruise
control provides a more relaxing driving expe-
rience 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 185)
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.

functionality with the adaptive cruise control's

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 181.
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 193) 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.
2Queue Assistant (in cars with automatic gearbox) can operate in the range of 0-200 km/h, see page 179.

•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 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/h8
•wheels lose traction
•brake temperature is high
•the radar sensor is covered e.g. by wet
snow or heavy rain (radar waves blocked).

Queue Assistant
In cars with automatic gearbox the adaptive
cruise control has the Queue Assistant function
(sometimes also referred to as "Queue
Assist").
Queue Assistant has the following functions:
•Extended speed range
•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 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.
8Does not apply to a car with Queue Assistant - it manages right down to stationary.

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.
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 192) and the Distance Warning function
(see page 185). The function of the radar sen-
sor 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.
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.
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

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.
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 Warning and Collision Warn-
ing with Auto Brake functions are not operating
either.
The following table presents possible causes
for a message being shown along with the
appropriate action.
