■
Starting the hybrid system when the 12-volt battery is discharged
The hybrid system cannot be started by push-starting.
■ To prevent 12-volt battery discharge
●Turn off the headlights and the audio system while the hybrid system is
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic.
■ Precautions when the 12-volt batter y is discharged (vehicles with a
smart key system)
● In some cases, it may not be possible to unlock the doors using the smart
key system immediately after the 12-volt battery has been disconnected
and reconnected. Use the wireless remote control or the mechanical key
to lock or unlock the doors.
● The hybrid system may not start on the first attempt after the 12-volt bat-
tery has recharged but will start normally after the second attempt. This is
not a malfunction.
● The “POWER” switch mode is memorized by the vehicle. When the 12-
volt battery is reconnected, the system will return to the mode it was in
before the 12-volt battery was discharged. Before disconnecting the 12-
volt battery, turn the “POWER” switch off.
If the “POWER” switch was in ACCESSORY or ON mode before the 12-
volt battery was discharged, the audio system and/or air conditioning
system may operate when the 12-volt battery is reconnected.
■ Charging the 12-volt battery
The electricity stored in the 12-volt battery will discharge gradually even
when the vehicle is not in use, due to natural discharge and the draining
effects of certain electrical appliances. If the vehicle is left for a long time, the
12-volt battery may discharge, and the hybrid system may be unable to start.
(The 12-volt battery recharges automatically while the hybrid system is oper-
ating.)
