Ashtrays 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. Climate Controls Climate Control System Notice: If you put papers or other flammable items in the ashtray, hot cigarettes or other smoking materials could ignite them and possibly damage your 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's ready, it will pop back out by itself. Notice: Holding a cigarette lighter in while it is heating will not allow the lighter to back away from the heating element when it is hot. Damage from overheating may occur to the lighter or heating element, or a fuse could be blown. Do not hold a cigarette lighter in while it is heating.
