*1: If the vehicle has not been used for a long time, the battery charge may be low and stop and start control operation may be prohibited. In this case, recharge the battery, initialize the integrated current* using the GTS and drive the vehicle approximately 5 to 40 minutes until stop and start control operation is permitted.

*: Use the GTS to perform Integrated Current Value Initialization.

Tip:

If the Data List item "Integrated Current" is 0 or higher, it is not necessary to perform initialization.
