Access key battery depletion
● The standard battery life is 1 to 2 years.
● If the battery charge becomes low, a buzzer will sound in the cabin and a
message will be displayed on the multi-information display when the
engine is stopped. ( →P. 446)
● As the access key always receives radio waves, the battery will become
depleted even if the access key is not used. The following symptoms
indicate that the access key battery may be depleted. Replace the bat-
tery when necessary. ( →P. 392)
• The keyless access with push button start system or the remote key- less entry system does not operate.
• The detection area becomes smaller.
• The LED indicator on the key surface does not turn on.
● To avoid serious deterioration, do not leave the access key close to any
of the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Glass top ranges
• Table lamps
■ When the access key battery is fully depleted
→ P. 392
■ If the keyless access with push button start system has been deacti-
vated in a customized setting
● Locking and unlocking the doors, unlocking the trunk lid: Use the remote
keyless entry system or mechanical key. ( →P. 38, 476)
● Starting the engine and changing push-button ignition switch modes:
→ P. 477
● Stopping the engine: →P. 4 7 9

red zone, a buzzer will sound and
a warning message will be dis-
played.
Engine oil temperature gauge
Displays the engine oil tempera-
ture.
Vo l t m e t e r
Displays the charging voltage.
As voltage displayed may
be different from the actual
battery voltage, use the volt-
meter as a guideline.
●Pressing and holding will turn the range value display on the
engine coolant temperature gauge display on/off.

BRZ_U (A4450BE-A)
■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.

Washer fluidIf the washer fluid level is at
“LOW”, add washer fluid.
CAUTION
■When recharging the battery
Never recharge the battery while the engine is running. Also, be sure all
accessories are turned off.
■ When adding distilled water
Avoid overfilling. Water spilled during battery recharging may cause corro-
sion.
■Using the gauge
The washer fluid level can be checked by
observing the position of the level on the
liquid-covered holes in the gauge.
If the level falls below the second hole
from the bottom (the “LOW” position),
refill the washer fluid.

5-2. Steps to take in an emergency
BRZ_U (A4450BE-A)
Stop the vehicle immediately.
The following warning indicates the possibility of damage to the vehi-
cle that may lead to an accident. Immediately stop the vehicle in a
safe place and contact your SUBARU dealer.
Warning lightWarning light/Details
Charging system warning light Indicates a malfunction in the vehicle’s charging system.
Low engine oil pressure warning light Indicates that the engine oil pressure is too low.
(Flashes or illu- minates in red) High engine coolant temperature warning light (if
equipped)
Indicates that the engine is almost overheating. ( →P. 485)
As the engine coolant temperature increases, this warning
light will change from flashing to constantly illuminated.

BRZ_U (A4450BE-A)
■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.
