Rear Ashtray
To use a rear ashtray, if you have them, pull at the top of
the ashtray door to flip the door open.
To remove a rear ashtray, press down on the inside tabs
and open the door fully.
To use the cigarette lighter, push it in all the way, and let
go. When it’s done heating, it will pop back by itself.
NOTICE:
Holding a cigarette lighter in with your hand
while it is heating can make it overload,
damaging the lighter and the heating element.
Just push the lighter all the way in and let go.
When it’s done heating, it will pop back by itself.
Accessory Power Outlets
Two auxiliary power outlets are located near the
cigarette lighter. Use these outlets to power mobile
telephones or other devices designed to operate with
vehicle electrical systems.
