Ashtray(s) and Cigarette Lighter The front ashtray is located near the center of the instrument panel or on the front console, if equipped. Pull on the ashtray door to open it. Notice: If papers, pins, or other flammable items are put in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage the vehicle. Never put flammable items in the ashtray. To remove the front ashtray pull the ashtray up. To use the cigarette lighter, push it in all the way, and let go. When it is ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating does not let the lighter back away from the heating element when it is hot.
