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
Towing a Trailer
WARNING!
Towing a trailer when using Adaptive
Cruise Control (ACC) can lead to serious
system failures which can cause severe
accidents.
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.
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.
Driver Assistance Systems
Using ACC on Hills
When driving on steep hills, ACC may
not detect a vehicle in your lane when
vehicle reaches the crest. Depending
on the speed, vehicle load, traffic
conditions, and the steepness of the
hills, ACC performance may be limited.
Lane Changing
ACC may not detect a vehicle until it is
completely in the lane in which you are
traveling.
