Instruments and Controls
• an acoustic signal is provided (if
provided), synchronously with the
message visualization.
When a failure occurs, the information
on the screen is replaced by the failure
information.
In case of any warning that includes
the activation of a specific hardware
warning light on the side sector of
the instrument cluster, the relative
message and icon on the display
is shown, (see example in picture)
following the logic described below.
At the end of the visualization time,
if the warning is still present, the
hardware warning light remain active
while the icon disappear from the
dedicated area on the display.
Priority Logic for Warning Messages
The failures are divided into two
groups: very serious (high priority) and
less serious (low priority) failures.
The visualization of the warning
messages is maintained for a long time
for the high priority messages and for
a shorter time for the low priority
messages.
The message is shown again, at every
key-on, until the relative malfunction
is solved.
In case of contemporary failure events,
high priority messages have priority of
visualization, then follows the failures
with low priority.
The visualization time can be
interrupted in two ways:
• disappearance of the malfunction
that provokes warning visualization;
• short pressure of the MENU button
on the left multifunction lever
behind the steering wheel. In
this case the screen before the
failure event shall be shown again,
but the relative warning light (if
present) shall remain active until the
malfunction is solved.
If, during visualization of a high
priority failure message, a low priority
failure occurs, it will wait until the
visualization cycle is completed and
then is displayed on the screen.
Subsequent visualization logic shall
remain “rolling”.
Information and Feedback Messages
The management of the visualization
of the information and feedback
messages on the screen is similar to
the one described for the warning
messages.
The only exception for information
messages is the absence of acoustic
signaling that accompanies the
message (except for some cases,
example: door open with car moving).
The feedback messages, that generally
indicate the activation/deactivation
of a specific function upon driver’s
request, remain valid the same
considerations described for the
visualization of the information
messages.
The prescriptions regarding
visualization logic of feedback
messages are the same as for the low
priority failure messages.
Rolling Mode Visualization
“Rolling” mode is a method of
visualization where the screens are
alternated depending on the priority
or appearance order of the relative
events.
“Rolling” mode is based on cycle
of visualizations. The total number
of cycles is able to cover the total
respective times of visualization.
