  7. Push and hold the top of this button located behind the shift lever.

The windows will automatically lower and the top will raise. A chime will sound when the top has raised completely.

After the top is fully raised, release the retractable hardtop button.

If the radio is on, you may notice a brief mute in sound. This is normal and due to a new audio system equalization being loaded for the vehicle with the top raised.

Under certain conditions, the Driver Information Center (DIC) may display messages regarding the retractable hardtop. See DIC Warnings and Messages for more information.

If the retractable hardtop does not operate, and there are no messages displayed on the Driver Information Center (DIC), then perform the "Power Window Initialize" steps under Power Windows .

  1. Lower both sun visors and open both doors.
  2. Use the key to open the trunk. See Keys and Trunk for more information.
