Open the fender fuse compartment (under the driver side window).
Press and hold the EXTEND switch to release the generator slide tray
Hold switch ON until the slide is fully extended.

CLOSE THE GENERATOR SLIDE:
Anthem/Cornerstone:
Turn the ignition ON and press and hold the RETRACT button to pull in the generator slide.

Once the slide is closed, start the engine and resume operation of the AC system until the
compressor cycles 3 times.
