If your vehicle has this feature, the cover on the passenger's side lower window will open so that the glass can be cleaned.

Caution: Never open the passenger side door glass with the ignition on. You can be injured if the window linkage moves. Open this glass only with the ignition off.

To open the window cover, pull on the latch at the rear of the window and swing the window cover open. When closing the window cover, push firmly at the latch to close completely.
