■
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. 387)
■ 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)
■ If the doors cannot be locked or unlocked by the keyless access with
push button start system
Lock and unlock the doors by the mechanical key or remote keyless entry
system.

Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.
Vehicles with a keyless access with push button start sys-
tem only: Open and close any of the doors of your vehicle
with the push-button ignition switch off.
Vehicles without a keyless access with push button start
system: Maintain the engine speed of the second vehicle
and turn the engine switch to the “ON” position, then start
the vehicle's engine.
Vehicles with a keyless access with push button start sys-
tem: Maintain the engine speed of the second vehicle and
turn the push-button ignition switch to “ON” mode, then
start the vehicle's engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your SUBARU
dealer as soon as possible.STEP 2

■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.
