Alarm system 
The alarm system helps to protect your vehicle and 
valuables from theft. The horn sounds and the turn
signal lights flash if someone attempts to break into your vehicle. 
The system can be armed and disarmed with the re- 
mote transmitter. 
The system does not operate when the key is inserted 
into the ignition switch. 
Your vehicle’s alarm system has been set for activa- 
tion at the time of shipment from the factory. You can 
set the system for deactivation yourself or have it done
by your SUBARU dealer. !System alarm operation
The alarm system will give the following alarms when 
triggered: " The vehicle’s horn will sound and the turn signal
lights will flash for 30 seconds. " If any door (or the rear gate/trunk lid) remains open
after the 30-second period, the horn will continue to
sound for a maximum of 3 minutes. If the door (or the
rear gate/trunk lid) is closed while the horn is sound- 
ing, the horn will stop sounding with a delay of up to 30 seconds.

Maintenance and service
Air cleaner element
Do not operate the engine with the air cleaner 
element removed. The air cleaner element not
only filters intake air but also stops flames if the 
engine backfires. If the air cleaner element is 
not installed when the engine backfires, you
could be burned.
The air cleaner element functions as a filter screen. 
When the element is perforated or removed, engine 
wear will be excessive and engine life shortened. 
The air cleaner element is a dry type. It is unnecessary 
to clean or wash the element. ! Replacing the air cleaner element
Replace the air cleaner element according to the 
maintenance schedule in the “Warranty and Mainte- 
nance Booklet”. Under extremely dusty conditions, re-
place it more frequently. It is recommended that you 
always use genuine SUBARU parts. !
