Engaging the cruise control functionBefore ACC can be used, it must first be put in
standby mode. To do so, press
. The symbol
illuminates in the display and (---) indicate
that ACC is in standby mode.Setting a speedUse the
or
buttons to store (set) the
vehicle's current speed. The set speed, for
example 55 mph, is shown in the display.
NOTE
Adaptive cruise control cannot be engaged
at speeds below 20 mph (30 km/h).
The “car” symbol illuminates
on the left side of the display
when the radar sensor
detects another vehicle
ahead. The distance to a vehi-
cle ahead is only regulated
when this symbol is illumi-
nated.
Adjusting the set speedAfter a speed has been set, it can be increased
or decreased by using the
or
buttons.
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 but-
tons is pressed for more than approxi-
mately one minute, ACC will be deacti-
vated. The engine must then be
switched off and restarted to reset ACC.
•
In some situations cruise control cannot
be activated.
Cruise Control
Unavailable is shown in the display,
see page 170.
Setting a time intervalThe set time interval to vehicles ahead is
increased with
and decreased with
.
The current time interval is shown briefly in the
display following adjustment.
Five 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 interval. At low
speeds, when the distance to
the vehicle ahead is short, ACC increases the
time interval slightly. In order to follow the vehi-
cle 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 acti-
vated, see page 172 .Deactivating and resuming settingsCruise control is deactivated, either with a
short press on
, or by action taken by the
driver, such as braking, etc. The set speed, for
example 55 mph, is then shown in parenthe-
ses. Speed and time interval are resumed by
pressing
.
WARNING
There may be a significant increase in speed
after the
button has been pressed.
A short press on
in standby mode or a long
press in active mode deactivates cruise con-trol. The set speed is then cleared and cannot
be resumed.
When ACC is activated, the vehicle’s speed
increases by approximately 1 mph (1 km/h)
each additional time
is pressed.
Deactivation due to action by the driverACC is deactivated:•
when the brakes are applied
•
if the gear selector is moved to N
•
if the accelerator pedal is depressed for an
extended period.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 deactivationAdaptive cruise control is linked to other sys-
tems such as ABS, the stability and traction
control system (DSTC), and the Distance Alert
System. If any of these systems are not func-
tioning properly, adaptive cruise control is
automatically deactivated.
In the event of automatic deactivation a signal
will sound and the message
Cruise Control
Canceled
is shown in the display. The drivermust then intervene and adapt the vehicle's
speed to the surrounding traffic.
Automatic deactivation may be caused if:
•
the vehicle's speed falls below 20 mph
(30 km/h)
•
the wheels lose traction or if the anti-lock
brake system (ABS) is activated
•
brake temperature is high
•
engine speed (rpm) is too low
•
the radar sensor is obstructed by, for
example, wet snow or rain.
The radar sensor and its limitationsThe radar sensor is used by both Adaptive
Cruise Control and the Collision Warning Sys-
tem with Auto-brake. It is designed to detect
cars or larger vehicles driving in the same
direction as your vehicle.
WARNING
Accessories or other objects, such as extra
headlights, must not be installed in front of
the grille.
Modification of the radar sensor could make
its use illegal.The radar sensor's capacity to detect vehicles
ahead is impeded:

•
if the radar sensor is obstructed and can-
not detect other vehicles, for example in
heavy rain, or if snow or other objects are
obscuring the radar sensor.NOTE
Keep the area in front of the radar sensor
clean.•
if the speed of vehicles ahead is signifi-
cantly different from your own speed.WARNING
The radar sensor has a limited field of vision.
In some situations it may detect a vehicle
later than expected or not detect vehicles at
all.
G021414
Radar sensor field of vision (gray)
In certain situations, the radar sensor can-
not detect vehicles at close quarters, for
example a vehicle that suddenly enters thelanes between your vehicle and the one
that the system has already detected.
Small vehicles, such as motorcycles, or
vehicles not driving in the center of the lane
may remain undetected.In curves, the radar sensor may detect the
wrong vehicle or lose a detected vehicle
from view.
Fault tracing and actionsIf 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 will not function.
The table lists possible causes for this mes-
sage being displayed, and suitable actions.
Cause
Action
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.

Cause
Action
Swirling water or snow from the surface of the road may interfere with
the radar signals.
No action possible. A very wet or snow-covered road surface may affect
the function of the radar.
The surface of the radar is clean but the message remains in the display.
Wait a short time. It may take several minutes for the radar to detect that
it is no longer obstructed.

04172
IntroductionDistance Alert is part of Adaptive Cruise Con-
trol and is a function that provides information
about the time interval to the vehicle ahead.
Time interval information is only given for a
vehicle that is driving ahead of your vehicle, in
the same lane, and in the same direction. No
information is provided for vehicles driving
toward you, moving very slowly, or at a stand-
still.
G017362
A smaller section of the red warning light in the
windshield glows steadily if your vehicle is
closer to the vehicle ahead than the set time
interval.
NOTE
Distance Alert is in active mode while Adap-
tive Cruise Control is active.
Distance Alert is active at speeds above
approximately 20 mph (30 km/h).
WARNING
Distance Alert only indicates the distance to
the vehicle ahead. It does not affect the
speed of your vehicle.Operation

NOTE
•
The higher your vehicle’s speed, the
greater the distance to the vehicle
ahead, measured in feet (meters), for a
given time interval.
•
The set time interval is also used by
Adaptive Cruise Control, see page 167.WARNING
Only use a time interval that is suitable in
current traffic conditions.
LimitationsThe Distance Alert function uses the same
radar sensor used by Adaptive Cruise Control
and the Collision Warning system. See page
168 for more information on the radar sensor’s
limitations.
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.
WARNING
•
Bad weather or winding roads may
affect the radar sensor’s capacity to
detect vehicles ahead.
•
The size of the vehicle ahead, such as a
motorcycle, may also make it difficult to
detect. This may result in the warning
light illuminating at a shorter distance
than the one that has been set, or that
the light will not come on at all.

The function is activated when the
vehicle exceeds a speed of 40 mph
(65 km/h). The display will show level
markings of 1–5 bars, where a low
number of bars indicates erratic driving. A high
number of bars indicates stable driving.
If the vehicle is being driven erratically, the
driver will be alerted by an audible signal and
the message Driver Alert, Time for a break is
displayed. The warning will be repeated after a
short time if the driving pattern remains the
same.
WARNING
•
An alert should be taken seriously since
it is sometimes difficult for a driver to
realize that he/she is fatigued.
•
In the event of a warning or if the driver
feels fatigued, stop as soon as possible
in a safe place and rest.
