■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 elec-
trical appliances. If the vehicle is left for a long time, the 12-volt battery may dis-
charge, and the engine may be unable to start. (The 12-volt battery recharges
automatically during driving.)
■When recharging or replacing the 12-volt battery
●Make sure that the key is not inside the vehicle when recharging or replacing the
12-volt battery. The key may be locked in the vehicle if the alarm is activated.
(  P. 8 9 )
●In some cases, it may not be possible to unlock the doors using the smart access
system with push-button start when the 12-volt battery is discharged. Use the wire-
less remote control or the mechanical key to lock or unlock the doors.
●The engine may not start on the first atte mpt after the 12-volt battery has recharged
but will start normally after the second attempt. This is not a malfunction.
●The “START STOP ENGINE” 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 “START STOP ENGINE” switch off.
If you are unsure what mode the “START STOP ENGINE” switch was in before the
12-volt battery discharged, be especially careful when reconnecting the 12-volt
battery.
CAUTION
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prev ent accidentally igniting the flammable
gas that may be emitted from the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal and that it is
not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+” terminal to
come into contact with any other parts or metal surfaces in the area, such as
brackets or unpainted metal.
●Do not allow the + and - clamps of the jumper cables to come into contact with
each other.
●Do not smoke, use matches, cigarette lighters or allow open flame near the 12-
volt battery.
