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.

or cancel by pressing EXIT.
Limitations
RSI's camera has the same limitations as the
human eye. See page 158 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

WARNING
Adaptive Cruise Control only warns of vehi-
cles detected by the radar sensor, see
page 140. 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.

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 143.
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 145 .
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.

138* Option/accessory, for more information, see Introduction.
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
3Does not apply to vehicles equipped with the optional Queue Assist

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.
Fault tracing and actions
If the message Radar blocked See manual is
displayed, this means that the radar signals
from the sensor have been obstructed and that
a vehicle ahead cannot be detected.
This, in turn, means that the functions of the
ACC, Distance Alert, and Collision Warning
System with Auto-brake and Pedestrian
Detection will not function.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
CauseAction
The surface of the radar in the grille is dirty or obstructed in some way.Clean the radar surface, or remove the object causing the obstruction.
Heavy rain or snow is interfering with the radar signals.No action possible. Heavy precipitation may affect the function of the
radar.
