■
Use a CR2016 (vehicles without a keyless access with push button
start system) or CR2032 (vehicles with a keyless access with push but-
ton start system) lithium battery
●
Batteries can be purchased at your SUBARU dealer, local electrical
appliance shops or camera stores.
●
Replace only with the same or equivalent type recommended by the
manufacturer.
●
Dispose of used batteries according to local laws.
■
If the key battery is depleted
The following symptoms may occur:
●
The keyless access with push button start system (if equipped) and
remote keyless entry system will not function properly.
●
The operational range will be reduced.
■

push button start system)
WARNING
■
Removed battery and other parts
Keep away from children. These parts are small and if swallowed by a child,
they can cause choking. Failure to do so could result in death or serious
injury.
Insert the module from directly above.
Inserting it on an angle may prevent the
key buttons from operating properly.

■
After a fuse is replaced
●
If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. (
→P. 400)
●
If the replaced fuse blows again, have the vehicle inspected by your
SUBARU dealer.
■
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
WARNING
■
To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
●
Never use a fuse of a higher amperage rating than indicated, or use any
other object in place of a fuse.
●
Always use a genuine SUBARU fuse or equivalent.
●
Do not modify the fuse or the fuse box.
CAUTION
■
Before replacing fuses
Have the cause of electrical overload determined and repaired by your
SUBARU dealer.
