  7. Push and hold the top of the retractable hardtop 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 you press the button again within five seconds, the windows will automatically close.

If your 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 a message regarding the retractable hardtop. If this happens, see DIC Warnings and Messages for more information.

Manually Raising the Retractable Hardtop

If your vehicle has a power loss, such as a dead battery, you can still raise the top manually by doing the following:

  1. Lower both sun visors and open both doors.
  2. Use the key to open the trunk. See Keys and Trunk for more information.
  3. Raise the trunk by hand.
  4. Remove the wrench located inside the passenger's side storage compartment.
