        Check the battery condition and recharge or replace the battery

        B

        Integrated current value is limited for stop and start control due to battery temperature (too high/low)

        Leave the battery under room temperature conditions until its temperature becomes as specified. Then check the battery condition and recharge or replace the battery.

        • After recharging the battery, initialize the integrated current value* and drive the vehicle until stop and start control operation is permitted (approximately 15 to 40 minutes).

          *: Disconnect the cables from the battery, wait for 30 seconds or more and then reconnect the cables.
