■Before recharging
When recharging, the battery produces hydrogen gas which is flammable
and explosive. Therefore, before recharging:
●If recharging with the battery installed on the vehicle, be sure to discon-
nect the ground cable.
● Make sure the power switch on the charger is off when connecting and
disconnecting the charger cables to the battery.
■ After recharging/reconnecting the battery (vehicles with a keyless
access with push button start system)
●Unlocking the doors using the keyless access with push button start sys-
tem may not be possible immediately after reconnecting the battery. If
this happens, use the remote keyless entry system or the mechanical
key to lock/unlock the doors.
● Start the engine with the push-button i gnition switch in “ACC” mode. The
engine may not start with the push-button ignition switch turned off. How-
ever, the engine will operate normally from the second attempt.
● The push-button ignition switch mode is recorded by the vehicle. If the
battery is reconnected, the vehicle will return the push-button ignition
switch mode to the status it was in before the battery was disconnected.
Make sure to turn off the engine before disconnect the battery. Take extra
care when connecting the battery if the push-button ignition switch mode
prior to discharge is unknown.
If the engine will not start even after multiple attempts, contact your
SUBARU dealer.

■
Stopping the engine
Vehicles with an automatic transmission: Shift the select lever to P and press
the push-button ignition switch as you normally do when stopping the
engine.
Vehicles with a manual transmission: Shift the shift lever to neutral and press
the push-button ignition switch as you normally do when stopping the
engine.
■ Replacing the key battery
As the above procedure is a temporary measure, it is recommended that the
access key battery be replaced immediately when the battery depletes.
(→ P. 392)
■ Alarm (if equipped)
Using the mechanical key to lock the doors will not set the alarm system.
If a door is unlocked using the mechanical key when the alarm system is set,
the alarm may be triggered. ( →P. 87)

■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ Avoiding a discharged battery
●Turn off the headlights and the air conditioning system while the engine 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, etc.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long time, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ Precautions when the battery is discharged (vehicles with a keyless
access with push button start system)
●In some cases, it may not be possible to unlock the doors using the key-
less access with push button start system when the battery is dis-
charged. Use the remote keyless entry system or the mechanical key to
lock or unlock the doors.
● The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a
malfunction.
● The push-button ignition switch mode is memorized by the vehicle. When
the battery is reconnected, the system will return to the mode it was in
before the battery was discharged. Before disconnecting the battery, turn
the push-button ignition switch off.
If you are unsure what mode the push-button ignition switch was in
before the battery discharged, be especially careful when reconnecting
the battery.
