Adaptive Cruise Control (ACC)*
04

* Option/accessory, for more information, see Introduction.155 Introduction
Adaptive Cruise Control (ACC) is an optional
system designed to assist the driver by main-
taining a set speed or a set time interval to the
vehicle ahead. It is primarily intended for use
on long straight roads in steady traffic, such as
on highways and other main roads.
When the driver has set the desired speed and
the time interval to the vehicle ahead, ACC
functions as follows:
•If there are no other vehicles in the lane
ahead of you, your vehicle will travel at the
set speed.
•If ACC's radar sensor detects a slower
moving vehicle in the lane ahead, the sys-
tem will adapt your vehicle's speed to help
maintain the set time interval to the vehicle
ahead. When there are no longer slower
moving vehicles ahead, your vehicle will
accelerate to resume the set speed.
If ACC is switched off completely or in standby
mode and your vehicle comes too close to
another vehicle ahead, the driver will be
warned by the Distance Alert system (see
page 165).
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.

Adaptive Cruise Control consists of:
•A cruise control system to maintain a set
speed
•A system to maintain a set distance to the
vehicle ahead, which is expressed as a
time interval. For example, you can choose
to remain approximately 2 seconds behind
the vehicle ahead. The actual distance
required to maintain a 2-second interval
will vary according the speed of the vehi-
cles.

156* Option/accessory, for more information, see Introduction.
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.
The distance to the vehicle ahead (in the same
lane) is monitored by a radar sensor. Your vehi-
cle's speed is regulated by accelerating and
braking. The brakes may emit a sound when
they are being modulated by the adaptive
cruise control system. This is normal.
WARNING
The brake pedal moves when the adaptive
cruise control system modulates the
brakes. Do not rest your foot under the
brake pedal.
The ACC system is designed to smoothly reg-
ulate speed. However, the driver must apply
the brakes in situations that require immediate
braking. This applies when there are great dif-
ferences in speed between vehicles, or if the
vehicle ahead brakes suddenly.
WARNING
Due to limitations in the radar sensor, brak-
ing may occur unexpectedly or not at all,
see page 160.
Adaptive Cruise Control can be put in active
mode at any permitted speed. However, if the
vehicle's speed falls below 18 mph (30 km/h)
or if engine speed (rpm) becomes too low, ACC
disengages (goes into standby mode) and will
no longer modulate the brakes
2. The driver will
then have to maintain a safe distance to the
vehicle ahead.
WARNING
When Adaptive Cruise Control is in standby
mode or is switched off completely, the
brakes will not be modulated automatically.
The driver must assume full control over the
vehicle.
Warning light—driver braking requiredAdaptive Cruise Control can exert brake force
that is equivalent to approximately 40% of the
vehicle's total braking capacity. In situations
requiring more brake force than ACC can pro-
vide and if the driver does not apply the brakes,
an audible signal from the Collision Warning
system will sound and warning light will illumi-
nate (see page 174) in the windshield to alert
the driver to react.
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.
2Does not apply to vehicles with the optional Queue Assist. See page 159 for more information.

158* 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 163.
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 165 .
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 125) and press
.

Driver Alert System*
04

* Option/accessory, for more information, see Introduction.181 Introduction
The Driver Alert System is designed to help a
driver who may be becoming fatigued or who
is inadvertently leaving the lane.
The Driver Alert System consists of two differ-
ent functions that can be switched on together
or separately.
•Driver Alert Control (DAC)
•Lane Departure Warning (LDW), see
page 184
When one or both of the functions has been
switched on, it is in standby mode and is acti-
vated when the vehicle exceeds a speed of
40 mph (65 km/h).
The function deactivates if the vehicle's speed
goes under 37 mph (60 km/h).
Both functions use a camera that is dependent
on the road/lane being clearly marked by pain-
ted lines on each side.
WARNING
The Driver Alert System does not function in
all situations and is designed to be a sup-
plementary aid. It is not, however, intended
to replace the driver’s attention and judge-
ment.
Driver Alert Control (DAC)–
introduction
This function is intended to alert the driver if
his/her driving becomes erratic, such as if the
driver is distracted or fatigued.
NOTE
The camera has certain limitations, see
page 160.
A camera monitors the painted lines marking
the lane in which the vehicle is traveling and
compares the direction of the road with the
driver’s movements of the steering wheel. The
driver is alerted if the vehicle does not follow
the lane smoothly.DAC is designed to help detect a slowly chang-
ing driving pattern. It is primarily intended to be
used on main roads and is not meant for use in
city traffic.
WARNING
•DAC is not intended to extend the dura-
tion of driving. Always plan breaks at
regular intervals to help remain alert.
•In certain cases, fatigue may not affect
the driver’s behavior. In situations of
this type, no warning will be provided.
Therefore, it is important to take breaks
at regular intervals, regardless of
whether or not DAC has given a warn-
ing.
LimitationsIn certain situations, DAC may provide warn-
ings even if the driver’s driving pattern has not
become erratic.
•if the driver is testing the LDW function
•in strong crosswinds
•on grooved road surfaces.
