System limitations
Fig. 159 On the instrument panel display: ini-
tial system self-calibr
ation indication.
Front Assist has certain limitations inherent to
the syst
em. Thus, in cert
ain cir
cumstances,
some of the reactions may be inappropriate
from the driver's standpoint. So pay attention
in order to intervene if necessary.
The following conditions may cause the
Front Assist not to react or to do so too
late:
●
In the first few instants of driving after
switching on the ignition, due to the system’s
initial auto-calibration. During this phase, the
instrument panel screen will display the fol-
lowing indication

Fig. 159.
Unrecognised objects
●
Vehicles travelling outside the reach of the
sensors at close range from your own vehicle.
●
Vehicles that suddenly change to the lane
on which your vehicle is travelling.
●
Pedestrians that cannot be recognised be-
cause they are partially or totally hidden.
●
Objects such as walls, posts, fences, trees
or garage doors.
●
Loads and accessories of other vehicles
that protrude over the sides, backwards or
over the top.
●
Vehicles that cross or approach in the op-
posite direction.
