      1. Opening/Ending Ceremony


        • An opening ceremony which allows for anticipation of a pleasant drive is used. The opening ceremony operates as follows:


          1. When the power switch is turned on (IG), the needles of the speedometer, hybrid system indicator, engine coolant temperature gauge and fuel gauge illuminate.

          2. Then, the gauges and panels of the speedometer, hybrid system indicator, engine coolant temperature gauge and fuel gauge and the multi-information display illuminate.

          3. When the power switch is turned off, the panels of the speedometer, hybrid system indicator, engine coolant temperature gauge and fuel gauge and the multi-information display fade out.

          4. Then, the needles of the speedometer, hybrid system indicator, engine coolant temperature gauge and fuel gauge fade out.
