System warnings
System warnings alert you to possible problems or malfunctions in your
vehicle’s operating systems.
In the event of a multiple warning situation, the message center will
cycle the display to show all warnings by displaying each one for four
seconds.
The message center will display the last selected feature if there are no
more warning messages.
Types of messages and warnings:
• Some messages will appear briefly to inform you of something you
may need to take action on or be informed of.
• Some messages will appear once and then again when the vehicle is
restarted.
• Some messages will reappear after clearing or being reset if a problem
or condition is still present and needs your attention.
• Some messages can be acknowledged and reset by pressing RESET.
This allows you to use the full message center functionality by clearing
the message.
