The cigar lighter (power outlet) fuses are fuse No.5 and fuse No.22 , located in the Engine Compartment Fuse Box .
The fuse panel is located in the lower passenger side area behind the kick panel.
The power distribution box is located in the engine compartment.
In vehicles with heated seats, there is a relay box situated beneath the driver’s seat that houses two relays—one for the driver’s heated seat and another for the passenger’s.
