133 Introduction
Examples of readable road signs
Road Sign Information (RSI) is a feature that
helps the driver see road signs with the posted
speed limit.
If the vehicle passes a sign showing the speed
limit, this will be displayed in the center con-
sole.
WARNING
RSI does not function in all situations and is
only intended to provide supplementary
information.
The driver is always responsible for operat-
ing the vehicle safely.
Operation
Registered speed information
When RSI registers a road sign showing the
speed limit, this sign is displayed as a symbol
on the instrument panel.

Limitations
RSI's camera has the same limitations as the
human eye. See page 161 for more informa-
tion about the camera's limitations.
Signs that indirectly indicate the speed limit
(such as a sign with a town's name and the
permitted speed limit) will not be registered by
RSI.
Other factors that may interfere with RSI
include:
•Faded signs
•Signs located in a curve

•During wheel spin or wheel lock-up.
•If the vehicle's speed is increased by using
the accelerator pedal for more than
1 minute.
The currently set speed will be saved in the
system's memory.
Temporary deactivationThe driver can temporarily deactivate cruise
control by pressing 0. The saved speed is
shown in brackets in the information display.
Resume set speedIf cruise control has been deactivated tempo-
rarily, it can be reactivated by pressing
. The
vehicle's speed returns to the most recently set
speed.
WARNING
There may be a significant increase in speed
after the button has been pressed.
Deactivation
Cruise control is disengaged by pressing or
by switching off the engine. The set speed is
cleared.
WARNING
Cruise control should not be used in heavy
traffic or when driving on wet or slippery
roads. Cruise control may not maintain set
speed on steep downgrades.

Adaptive Cruise Control (ACC)*
04
* Option/accessory, for more information, see Introduction.137 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 148).
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.
Function

Warning light, braking by driver required
Controls in steering wheel
Radar sensor in front grille
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.

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 143.
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 158) 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 141 for more information.

WARNING
Adaptive Cruise Control only warns of vehi-
cles detected by the radar sensor, see
page 143. In some cases there may be no
warning or the warning may be delayed. The
driver should always apply the brakes when
necessary.
Steep inclines and/or heavy loadsACC is primarily intended for use on fairly level
roads. The system may have difficulty main-
taining the correct distance to a vehicle ahead
on steep inclines, if the vehicle is carrying a
heavy load or is towing a trailer. In these situa-
tions, the driver should always be prepared to
apply the brakes if necessary.

first be put in standby mode.
To do so:
Press
.
The
symbol appears in the display and
parentheses (---) indicate that ACC is in
standby mode.
NOTE
The driver's door must be closed and the
driver's seat belt must be fastened before
ACC can be put in active mode. If the driv-
er's seat belt is taken off or if the driver's
door is opened, ACC will return to standby
mode.
Setting a speedOnce ACC has been put in standby mode, use
the
or buttons to store (set) the vehicle's
current speed. This puts the system in active
mode. The set speed, for example 55 mph, is
shown in the display.

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 146.
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 3 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 situa-
tions.
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 148 .
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:
•if the brakes are applied
•if the gear selector is moved to N
•if the driver drives at a speed higher than
the set speed for more than 1 minute.
In this happens, the driver will have to regulate
the vehicle's speed.
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 thevehicle's speed to the surrounding traffic and
regulate the distance to the vehicle ahead.
An automatic switch to standby mode may be
caused if:
•engine speed (rpm) is too high/low
•the vehicle's speed goes below 18 mph
(30 km/h)3
•the wheels lose traction
•brake temperature is high
•the radar sensor is obstructed by, for
example, wet snow or rain.
Resuming the set speedIf ACC is in standby mode, it can be reactivated
by pressing the
button on the steering
wheel keypad. The vehicle will return to the
most recently set speed.
WARNING
The vehicle may accelerate quickly after has been pressed if its current speed is
considerably lower than the set speed.
Passing another vehicleIf your vehicle’s speed is being regulated by
ACC and the driver indicates that he/she would
like to pass the vehicle ahead by using theleft turn signal, ACC can assist by accelerating
briefly.
This function is active at speeds above approx-
imately 45 mph (70 km/h).
WARNING
Please be aware that this function will also
cause the vehicle to accelerate briefly in
certain situations other than passing
another vehicle, for example using the left
turn signal to indicate a lane change or a
turn toward a highway exit at speeds above
approximately 45 mph (70 km/h).
Queue AssistQueue Assist is an added ACC feature that is
linked to your vehicle's automatic transmis-
sion.
Queue Assist consists of the following func-
tions:
•Enhanced speed interval (including when
the vehicle is at a complete stop or is mov-
ing at speed below 18 mph (30 km/h))
•Automatic standby mode when ACC
changes target vehicles
•No automatic braking when at a standstill
•The parking brake is applied automatically

142* Option/accessory, for more information, see Introduction.
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 interval
NOTE
The driver's door must be closed and the
driver's seat belt must be fastened before
ACC can be put in active mode. If the driv-
er's seat belt is taken off or if the driver's
door is opened, ACC will return to standby
mode.
Your 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 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). ACC will then resume following
the vehicle ahead.
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 4 minutes. After
4 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).
Automatic standby mode when ACC
changes target vehicles
If the vehicle ahead turns suddenly, there may be
a stationary vehicle ahead
The following only applies at speeds below
approximately 18 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 18 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:
