may have occurred. The possible reasons
of this limitation are something blocking
the camera view or a fault.
In this condition it will still be possible
to drive the car normally, but automatic
braking will not be available in the event
of an impending collision.
If an obstruction is signalled, clean the
area of the windscreen indicated in
fig. 69.
When the conditions limiting the system
functions end, this will go back to normal
and complete operation. Should the
fault persist, contact an Alfa Romeo
Dealership.
System failure signalling
If the system switches off and a
dedicated message is shown on the
display, it means that there is a fault on
the system.
In this case, it is still possible to drive the
vehicle, but you are advised to contact
an Alfa Romeo Dealership as soon as
possible.
Radar indication not available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message appears on the display.
This generally occurs in the event of poor
visibility, such as when it is snowing or
raining heavily.
The system can also be temporarily
dimmed due to obstructions such as
mud, dirt or ice on the bumper. In such
cases, a dedicated message will be
shown on the display and the system
will be deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflective
tiles or ice or snow).
When the conditions limiting the system
functions end, this will go back to normal
and complete operation.
In certain particular cases, this dedicated
message could be displayed when the
radar is not detecting any vehicles or
objects within its view range.
If atmospheric conditions are not the real
reason behind this message, check if the
sensor is dirty.
It could be necessary to clean or remove
any obstructions in the area shown in
fig. 68.
If the message appears often, even in the
absence of atmospheric conditions such
as snow, rain, mud or other obstructions,
contact an Alfa Romeo Dealership for a
sensor alignment check.
In the absence of visible obstructions,
cleaning the radar surface, by manually
removing the decorative cover trim,
could be required. Have this operation
performed at an Alfa Romeo Dealership.
WARNING It is recommended that you
do not install devices, accessories or
aerodynamic attachments in front of the
sensor or darken it in any way, as this can
compromise the correct functioning of
the system.
Frontal collision alarm with active
braking
(where provided)
If this function is selected, the brakes are
operated to reduce the speed of the car
in the event of potential frontal impact.
This function applies an additional
braking pressure if the braking pressure
applied by the driver does not suffice to
prevent potential frontal impact.
The function is active with speed above
2.5 mph (4 km/h).
Driving in special conditions
In certain driving conditions, such as, for
example:
driving close to a bend;
the vehicle ahead is leaving a
roundabout;
vehicles with small dimensions and/or
not aligned in the driving lane;
lane change by other vehicles;
vehicles travelling at right angles to
the vehicle;
System intervention might be
unexpected or delayed. The driver must
therefore be very careful, keeping
