646 8-2. Steps to take in an emergency
● Turn off any unnecessary electrical components when the vehicle is running at a low speed for an extended period, such as in heavy traffic.
●When ACC customization is in off, power is still provided to the multimedia system even though the
power switch is off. To turn off the multimedia system, use the multimedia system power switch. For
details, refer to the“ MULTIMEDIA OWNER’ S MANUAL”.
■ 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 EV system may be unable to start.( The 12-volt battery
recharges automatically while the EV system is operating.)
■ When the 12-volt battery is removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery
is depleted, have the vehicle inspected at your SUBARU dealer.
●In some cases, it may not be possible to unlock the doors using the
smart key system when the 12- volt battery is discharged. Use the wireless remote control or the
mechanical key to lock or unlock the doors.
●The EV system may not start on the first attempt after the 12-volt battery 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 you are unsure what mode the
power switch was in before the 12-volt battery discharged, be especially careful when reconnecting the 12-volt battery.
●If the 12-volt battery discharges, it may not be possible to shift the shift position to other positions. In this case, the vehicle cannot be
towed without lifting both front wheels because the front wheels will be locked.
●The power back door( if equipped) must be initialized.( �P. 172)
■ When replacing the 12-volt battery
●Use a 12-volt battery that conforms to European regulations.
●Use a 12-volt battery that the case
size is same as the previous one( LN1), 20 hour rate capacity( 20HR) is equivalent( 45Ah) or
greater, and performance rating( CCA) is equivalent( 286A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.
• If an improper 12-volt battery is
used, battery performance may decrease and the EV system may not be able to restart.
• If the 20 hour rate capacity is low, even if the time period where the vehicle is not used is a short time,
the 12-volt battery may discharge and EV system may not be able to start.
For details, consult your SUBARU dealer.
