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
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 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 area in front of the radar sensor
clean - see "Maintenance" on page 176.
•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.

162* Option/accessory, for more information, see Introduction.
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.
This means that in addition to the Adaptive
Cruise Control, Distance Warning and CollisionWarning with Auto Brake functions are not
operating either.
The following table presents possible causes
for a message being shown along with the
appropriate action.
CauseAction
The radar surface in the grille is dirty or covered with ice or snow.Clean the radar surface in the grille from dirt, ice and snow.
Heavy rain or snow blocking the radar signals.No action. Sometimes the radar does not work during heavy rain or
snowfall.
Water or snow from the road surface swirls up and blocks the radar sig-
nals.No action. Sometimes the radar does not work on a very wet or snowy
road surface.
The radar surface has been cleaned but the message remains.Wait. It could take several minutes for the radar to sense that it is no
longer blocked.

Cruise control UnavailableAdaptive cruise control cannot be activated.
This could be due to:
•brake temperature is high
•the radar sensor is blocked by e.g. wet snow or rain.
Radar blocked See manualAdaptive cruise control temporarily disengaged.
•The radar sensor is blocked and cannot detect other vehicles. For example, in the event that heavy
rain or if slush has collected in front of the radar sensor.

(Only with Queue Assistant)The car is stationary and the cruise control will release the foot brake to allow the parking brake to
take over and hold the car, but a fault in the parking brake means the car will shortly begin to roll.
•The driver must brake himself/herself. The message remains and the alarm sounds until the driver
depresses the brake pedal or uses the accelerator pedal.

Distance Warning*
04
* Option/accessory, for more information, see Introduction.165 General
Distance Warning (Distance Alert) is a function
that informs the driver about the time interval
to vehicles in front.
Distance Warning is active at speeds above
30 km/h and only reacts to vehicles driving in
front of the car, in the same direction. No dis-
tance information is provided for oncoming,
slow or stationary vehicles.
Orange warning lamp1.
An orange warning lamp in the windscreen illu-
minates with a constant glow if the distance to
the vehicle in front is shorter than the set time
interval.
NOTE
Distance warning is deactivated during the
time the adaptive cruise control is active.
WARNING
Distance warning only reacts if the distance
to the vehicle ahead is shorter than the pre-
set value - the speed of the driver's vehicle
is not affected.
Operation
Press the button in the centre console to switch
the function on or off. The function is switched
on if one lamp is illuminated in the button.Some combinations of the selected equipment
leave no vacant space for a button in the centre
console - in which case the function is handled

166* Option/accessory, for more information, see Introduction.
Different time intervals to the
vehicle in front can be
selected and shown in the
display as 1-5 horizontal lines
- the more lines the longer the
time interval. One line corre-
sponds to
approximately 1 second to the vehicle in front,
5 lines approximately 3 seconds.
The number of lines for the
selected time interval is
shown during the setting itself
and for several seconds after-
wards. Then a smaller scale
version of the symbol is
shown to the right of the dis-
play. The same symbol is also shown when
adaptive cruise control is activated.
NOTE
The higher the speed, the longer the calcu-
lated distance in metres for a specific time
interval.
The set time interval is also used by the
adaptive cruise control function, see
page 156.
Only use the time interval that is allowed in
accordance with local traffic regulations.
Limitations
The function uses the same radar sensor as
adaptive cruise control and the collision warn-
ing system. For more information on the radar
sensor and its limitations, see page 160.
NOTE
Strong sunlight, reflections or strong varia-
tions in light intensity, as well as wearing
sunglasses, could mean that the warning
light in the windscreen cannot be seen.
Poor weather or winding roads could affect
the radar sensor's capacity to detect vehi-
cles in front.
The size of other vehicles could also affect
detection capacity, e.g. motorcycles. This
could mean that the warning lamp illumi-
nates at a shorter distance than the setting
or that the warning is temporarily absent.
Extremely high speeds can also cause the
lamp to illuminate at a shorter distance than
that set due to limitations in sensor range.

176* Option/accessory, for more information, see Introduction.
Activating/deactivating warning signalsThe warning lamp (no. [1] in the illustration on
page 173) is activated automatically when the
engine is started if Collision Warning is ena-
bled.
The warning sound can be activated/deacti-
vated separately:
•Select On or Off in the menu system MY
CAR under Settings
Car settings
Driver support systemsCollision
Warning
Warning sound.
Set warning distanceThe warning distance regulates the distance at
which the visual and acoustic warnings are
deployed.
•Select one of the options from Long,Normal or Short in the menu system MY
CAR under Settings
Car settings
Driver support systemsCollision
Warning
Warning distance.
The warning distance determines the system's
sensitivity. Warning distance
Long provides an
earlier warning. First test with Long and if this
setting produces too many warnings, which
could be perceived as irritating in certain sit-uations, then change to warning distance
Normal.
Only use warning distance
Short in excep-
tional cases, e.g. for dynamic driving.
NOTE
When the adaptive cruise control is in use
the warning lamp and warning sound will be
used by the cruise control even if the colli-
sion warning system is switched off.
The collision warning system warns the
driver in the event of a risk of a collision, but
the function cannot shorten driver reaction
time.
In order for the collision warning system to
be effective, always drive with the Distance
Alert set at time interval 4 – 5. see
page 165.
NOTE
Even if the warning distance has been set toLong warnings could be perceived as being
late in certain situations, e.g. when there are
large differences in speed or if vehicles in
front brake heavily.
WARNING
No automatic system can guarantee
100 % correct function in all situations.
Therefore, never test the Auto Brake system
by driving at people or vehicles - this may
cause severe damage and injury and risk
lives.

For the sensors to work correctly, they must be
kept clear of dirt, ice and snow, and be cleaned
regularly with water and car shampoo.
NOTE
Dirt, ice and snow covering the sensors will
reduce their function and may prevent
measurement.
Limitations
Collision Warning with Auto Brake and Pedes-
trian Detection is active from approx. 4 km/h.
The visual warning signal (no. [1] in the illustra-
tion on page 173) may be difficult to notice in
the event of strong sunlight, reflections, when
sunglasses are being worn or if the driver is not
looking straight ahead. The warning sound
should therefore always be activated.
On slippery road surfaces the braking distance
is extended, which may reduce the capacity to
avoid a collision. In such situations the ABS
and DSTC systems will provide best possible
braking force with maintained stability.
NOTE
The visual warning signal can be temporarily
disengaged in the event of high passenger
compartment temperature caused by
strong sunlight for example. If this occurs
then the warning sound is activated even if
it is deactivated in the menu system.
•Warnings may not appear if the dis-
tance to the vehicle in front is small or if
steering wheel and pedal movements
are large, e.g. a very active driving style.
WARNING
Warnings and brake interventions could be
implemented late or not at all if the traffic
situation or external influences mean that
the radar or camera sensor cannot detect a
pedestrian or a vehicle in front correctly.
The sensor system has a limited range for
pedestrians and the system therefore pro-
vides effective warnings and brake inter-
ventions at vehicle speeds up to 50 km/h.
For stationary or slow-moving vehicles,
warnings and brake interventions are effec-
tive at vehicle speeds up to 70 km/h.
Warnings for stationary or slow-moving
vehicles could be disengaged due to dark-
ness or poor visibility.
Warnings and brake interventions for
pedestrians are switched off at vehicle
speeds exceeding 80 km/h.
The collision warning system uses the same
radar sensors as adaptive cruise control. For
more information on the radar sensor and its
limitations, see page 178.
If warnings are perceived as being too frequent
or disturbing then the warning distance can be
reduced. This then leads to the system provid-
ing a warning at a later stage, which reduces
the total number of warnings; see the section
"Set warning distance" on page 176.
