■Remaining hybrid battery (tract ion battery) charge display
The charge amount of the hybrid battery (traction battery) is automatically
controlled by the hybrid system. For this reason, even if electricity is recov-
ered via the regenerative braking, or el ectricity is generated via the gasoline
engine, the displayed hybrid battery (traction battery) charge amount may not
reach the highest level (level 8). However, this does not indicate a malfunc-
tion.

Selecting “Clear” on the “Trip Information” screen will reset the fuel consump-
tion and the regenerated energy for the past 15 minutes. Selecting “Clear” on
the “Past Record” screen will reset the past records and best past fuel con-
sumption. Selecting “Yes” on the following screen will confirm resetting of all
the data.
