Rear Window Defrost

When the rear window defrost switch (integral to the FCIM) is activated, the FCIM activates the rear window defrost relay (integral to the BJB).

If equipped, the rear window defrost can also be commanded on and off using voice commands or by touching the rear window defrost button located on the touchscreen interface (FDIM). For additional information on voice or touchscreen commanded features, refer to the Owner's Literature.

The FCIM deactivates the rear window defrost relay when one of these conditions is met:

• The rear window defrost switch is pressed when the feature is active.
• If equipped, the rear window defrost is commanded off using voice command or the touchscreen interface when the feature is active.
• Ignition state is changed from ON to OFF.
• A predetermined timer completes.
• Battery voltage has dropped below a specified threshold (load management strategy).
