1High Voltage Battery Charge Level Gauge
When the number of bars displayed on the High
Voltage Battery Charge Level Gauge becomes 2,
assist by the high-voltage battery is limited and the
vehicle output is lowered.
The high voltage battery charge 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 reading 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 temperature changes cause the
battery's capacity to change, the number of
indicators in the battery charge level gauge may also
change, even if the amount of charging remains the
same.
