mable and explosive. Therefore, observe the following precautio ns before
recharging:
● If recharging with the 12-volt battery installed on the vehicle, be sure to dis-
connect the ground cable.
● Make sure the power switch on the charger is off when connecting and dis-
connecting the charger cables to the 12-volt battery.
■ After recharging/reconnecting the 12-volt battery
● The hybrid system may not start. Follow the procedure below to initialize the
system.
Shift the shift lever to P.
Open and close any of the doors.
Restart the hybrid system.
● Vehicles with entry function: Unlocking the doors using the smart entry &
start system may not be possible immediately after reconnecting the 12-volt
battery. If this happens, use the wireless remote control or th e mechanical
key to lock/unlock the doors.
● Start the hybrid system with the power switch in ACCESSORY mode. The
hybrid system may not start with the power switch turned off. H owever, the
hybrid system will operate normally from the second attempt.
● The power switch mode is recorded by the vehicle. If the 12-volt battery is
reconnected, the vehicle will return the power switch mode to t he status it
was in before the 12-volt battery was disconnected. Make sure t o turn off
the power switch before disconnect the 12-volt battery. Take ex tra care
when connecting the 12-volt battery if the power switch mode pr ior to dis-
