Driver Controls
The message center will display the last selected feature if there are no
more warning messages. This allows you to use the full functionality of
the message center after you acknowledge the warning by pressing the
SELECT/RESET control and clearing the warning message.
Warning messages that have been reset are divided into two categories:
• They will reappear on the display ten minutes from the reset.
• They will not reappear until an ignition OFF-RUN cycle has been
completed.
This acts as a reminder that these warning conditions still exist within
the vehicle.
