Ashtrays and Lighter
The center front ashtray is located just below the
instrument panel's comfort controls at the front of the
console. To remove the ashtray, open the front
compartment storage door. Then open the small black
door, lift up on the ashtray and pull it out.
The rear ashtray is located within a small door at the rear
of the console. Push on the right side of the door. The
ashtray will then rotate to the right for usage. You can
only access the ashtray by pushing on the door's right
side. To remove the ashtray, push down on the snuffer
located in the middle of the ashtray and lift it out.
NOTICE:
Don't put papers and other things that burn
into your ashtrays. If you do, cigarettes or
other smoking materials could set them on fire,
causing damage.
To use the lighter, just push it in all the way and let go.
When it's ready, it will pop back by itself.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overheat, damaging the
lighter and the heating element.
