Shows the remaining high voltage battery charge level.
■High Voltage Battery Charge Level Gauge1High Voltage Battery Charge Level Gauge
When the number of bars displayed on the High 
Voltage Battery Charge Level Gauge becomes one, 
assist by the high-voltage  battery is limited and the 
vehicle output is lowered.
The high voltage battery ch arge level may decrease 
under the following conditions:
•When the 12-volt battery has been replaced.•When the 12-volt battery has been disconnected.
•When the high voltage battery control system 
corrects its reading.
The charge level readi ng will be corrected 
automatically while driving.
Changes in the temperature of the high voltage 
battery can increase or  decrease the battery’s 
charging capacity. If temp erature changes cause the 
battery’s capacity to  change, the number of 
indicators in the battery ch arge level gauge may also 
change, even if the amount of charge remains the 
same.
