If your vehicle has this option, the switches are located on the headliner between the sun visors.

There are two switches that operate the sunroof. The switches will only work when the ignition is on or when RAP is active. See "Retained Accessory Power (RAP)" under Ignition Positions .

The OPEN/CLOSE switch has positions for open or close and express open. The TILT/CLOSE switch has positions for tilt or close.

Open: Press and hold the OPEN/CLOSE switch to the first position to open the glass panel and sunshade. The sunshade can also be opened by hand.

Comfort Stop: Press and release the OPEN/CLOSE switch rearward to the second position to express open the glass panel to the comfort stop position. The comfort stop position is designed to help reduce noise and make the passengers more comfortable.

Express Open: The glass panel may be fully opened by pressing the OPEN/CLOSE switch rearward again. When the glass panel is express opening, pressing either switch in any direction will stop it. If you press and hold the OPEN/CLOSE switch in the express open position for more than one and a half seconds, the express open operation will be overridden and the sunroof will operate manually.

Tilt: To tilt open the glass panel, press and hold the TILT/CLOSE switch. The sunshade must be opened by hand.

Close: To close the glass panel, press and hold the OPEN/CLOSE or TILT/CLOSE switch in the close position. As the glass panel reaches the closed position, it will open slightly towards the tilt position and then drop down to the closed position to provide a better seal.
