on the inside of glass or when driving in
bad weather.
In these cases, the system will have
degraded performance.
The ACC and FCW systems will recover
operation after the vehicle has left these
areas. Under rare conditions, when the
camera is not tracking any vehicles or
objects in its path this warning may
temporarily occur.
If weather conditions are not a factor,
the driver should examine the windshield
and the camera. They may require
cleaning or removal of an obstruction.
When the condition that created limited
functionality is no longer present, the
ACC and FCW systems will return to full
functionality.
NOTE:
If the windshield wiper warning
message occurs frequently (e.g. more
than once on every trip) without any
snow, rain, mud, or other obstruction,
have the windshield and forwardfacing
camera inspected at an Authorized
Maserati Dealer.
Service ACC/FCW Warning
If the ACC and FCW systems turn off,
and the system displays a service
warning, there may be an internal system
fault or a temporary malfunction that
limits functionality.
Although the vehicle is still driveable
under normal conditions, ACC and FCW
will be temporarily unavailable. If this
occurs, try activating ACC and FCW
again later, following an ignition cycle.
If the problem persists, contact an
Authorized Maserati Dealer.
Precautions while Driving with
ACC
Offset Driving
ACC may not detect a vehicle in the
same lane that is offset from your direct
line of travel, or a vehicle merging in from
a side lane. There may not be sufficient
distance to the vehicle ahead. The offset
vehicle may move in and out of the line
of travel, which can cause your vehicle
to brake or accelerate unexpectedly.
Driving and Driver Assistance Systems
Turns and Bends
When driving on a curve with ACC
engaged, the system may decrease
the vehicle speed and acceleration for
stability reasons, with no target vehicle
detected. Once the vehicle is out of
the curve the system will resume your
original set speed. This is a part of
normal ACC system functionality.
Moreover, the radar sensor might detect
a vehicle on a nearby lane or no longer
detect the target vehicle.
