The instrument cluster includes the analog
instruments. It also presents two devices to
communicate information to the driver, the
telltale lights and the Driver Information Display
(DID).
Indications and warnings are presented
according to three levels of attention required:
1. THE TELLTALE LIGHTS
The highest level of attention. The telltale lights
are temporary and exceptional; they present
information critical to safety or vehicle integrity.
2. POP-UP MESSAGES
The second level of attention. Pop-up messages
appear in the Driver Information Display DID
without the driver’s intervention and
acknowledgement. Pop-up messages present
supplemental information to the driver.
3. THE STATUS LINE
The lowest level of attention. The status line
monitors certain systems and gives feedback to
the driver concerning current actions and
functions.
