The 1st generation Toyota Highlander was produced in 2000, 2001, 2002, 2003, 2004, 2005, 2006 and 2007 with the U20 designation. In some countries it is known as Toyota Kluger V. In this publication we will show the locations of the electronic control units, describe in detail the fuses and relays of the Toyota Highlander 1 Kluger with box diagrams and photo examples of their execution. Note the cigarette lighter fuse.
The arrangement of blocks and elements in them may differ from that shown and depends on the year of manufacture, the level of equipment and the region of delivery. Check the information with your diagrams on the box cover.

There is something to add to the material – write in the comments.
Its good siet I like it
My fuse boxes look nothing like these fuse boxes. I have a 2008 right hand drive Toyota kluger. I had to put a new alternator in it plus a brand new battery. Now it won’t start. Power is going to everywhere accept power windows, and ignition. Although the lights on the ignition panel come on. I think the problem lies the the ABS and brake malfunction lights coming on.
Where is the fuse for the cruise control, for a 2007 Kluger Grande?
