      If the SOC is substantially below 40%, the auxiliary battery may go dead. Therefore, do not allow the SOC to reach substantially below 40%.

    8. Move the shift lever to the P position and turn the ignition switch off.
    9. Disconnect the negative terminal from the auxiliary battery and leave it for 1 minute or more.
    10. Reconnect the negative terminal to the auxiliary battery and turn the ignition switch to the ON position.
    11. Select the following menu items: DIAGNOSIS /ENHANCED OBD II / DATA LIST / PRIMARY / COOLANT TEMP.
    12. Check that the engine coolant temperature is 83°C (181°F) or more.

      HINT:

      If the engine coolant temperature is below 83°C (181°F), start the engine by depressing the accelerator pedal with the shift lever in the P position to increase the coolant temperature.

    13. Select the following menu items: DIAGNOSIS / ENHANCED OBD-II / DATA LIST / PRIMARY /CALC LOAD.
