STARTING AND DRIVING

vehicle ahead, the system could continue
the deceleration, if necessary, also after
it is cancelled or deactivated within the
minimum speed settable on the system.
SYSTEM LIMITED OPERATION
WARNING
If the dedicated message is shown on
the instrument panel display, a condition
limiting the system operation may have
occurred. The possible reasons of this
limitation are something blocking the
camera view or a fault.
In case of obstruction or blinding of the
camera (e.g. caused by low sun in front
of the windscreen or in the conditions
of fog or heavy rain), wait until the light
and glare conditions cease and allow
the system to operate fully or clean the
windscreen.
If an obstruction is signalled, clean the
area of the windscreen indicated in
fig. 164 and check that the message has
disappeared.
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.
PRECAUTIONS WHILE DRIVING
The system may not work correctly in
some driving conditions (see below): the
driver must control the car at all times.
Vehicle not aligned
The system may not detect a vehicle
travelling on the same lane but which is
not aligned along the same direction of
travel or a vehicle which is cutting in from
a side lane. Sufficient distance from the
vehicles ahead may not be guaranteed in
these cases.
The non-aligned vehicle can weave in and
out of the driving direction causing the
car to brake or accelerate unexpectedly.
Steering and curves
On bends fig. 173 with the system set,
it could limit speed and acceleration to
guarantee car stability even if no cars are
detected ahead.
When leaving the bend, the system tends
to reset the previously set speed.

WARNING In case of narrow bends, the
performance of the system could be
limited. In this case, it is advisable to
deactivate the device.
Using the system on gradient
When driving on roads with variable
gradient, the system may not detect
the presence of a vehicle on the
lane. The system performance be
limited according to speed, load of the
car, traffic conditions and gradient
steepness.
Lane change
The system may not detect the presence
of a vehicle until it is fully in your lane
fig. 174.
In this case, sufficient distance from
the vehicle which is changing lane may
not be guaranteed: it is advisable to pay
the utmost attention at all times and
be always ready to press the brakes if
needed.

Small vehicles
Some narrow vehicles (e.g. bicycles and
motorcycles fig. 175) travelling near the
outer edges of the lane or which enter
