Fail-Safe Function

The center display unit performs the fail-safe control when the system detects an abnormal high temperature in the unit:

• When the center display unit temperature rises over about 149 deg.F (65 deg.C), the display brightness dims gradually.
• When the center display unit temperature rises over 176 deg.F (80 deg.C), the center display unit sends the error status to the audio-navigation unit, and the center display unit displays the error message for 30 seconds and then the display back light turns off.
• When the center display unit temperature drops to below 167 deg.F (75 deg.C), the display back light turns on, and the display brightness returns gradually with the temperature drops.
