Your car should have come with a medium thick book that shows the various fuse boxes and locations/purpose of each fuse. The cigar lighter fuse is contained in the fuse box that is located just under the steering wheel. You need to find the very bottom lever and pull it out, then the panel will come forward to expose th e fuse block.
On the 2006 CGT it is fuse#84 for front and #85 for rear (both are 15A fuses). The fuses are located on the lowermost row, 6 and 7 if you count them from left to right.
The yellow coloured tool to remove the fuses are located in the trunk on the left side by the battery.
