1. Insert a key or other hard pointed ob-
ject into the slot in the connector (buckle)
on the right-hand side and push it in, and
the connector (tongue) plate will discon-
nect from the buckle.
2. Allow the retractor to roll up the belt. You should hold the webbing end and
guide it back into the retractor while it is
rolling up. Insert the tongue plate into the
belt holder.
Seatbelt maintenance
To clean the seatbelts, use a mild soap
and lukewarm water. Never bleach or dye
the belts because this could seriously af-
fect their strength.
Inspect the seatbelts and attachments in-
cluding the webbing and all hardware pe-
riodically for cracks, cuts, gashes, tears,
damage, loose bolts or worn areas. Re-
place the seatbelts even if only minor
damage is found.
100118
100289
Do not allow the retractor to roll
up the seatbelt too quickly. Other-
wise, the metal tongue plates may
hit against the trim, resulting in
damaged trim.
Have the seatbelt fully rolled up
so that the tongue plates are neat-
ly stored. A hanging tongue plate
can swing and hit against the trim
during driving, causing damage to
the trim.
100290Keep the belts free of polishes,
oils, chemicals and particularly
battery acid.
Never attempt to make modifica-
tions or changes that will prevent
the seatbelt from operating prop-
erly.

Manual tuning (TUNE)
Push the “ ” side of the tuning button
(3) to increase the tuning frequency and
press the “ ” side of the button to de-
crease it.
Each time the button is pressed, the fre-
quency changes 10 KHz in the AM wave-
band and 0.2 MHz in the FM waveband.
Constant pressure on the button causes a
continuous change in the frequency.
Automatic tuning (SCAN)
Press the “SCAN ” button (1) to change the
radio to the SCAN mode. In this mode, the
radio scans through the radio band until a
station is found. The radio will stop at the
station for five seconds while displaying
the frequency, after which scanning will
continue until the entire band has been
scanned from the low end to the high end.
Press the “SCAN ” button again to cancel
the SCAN mode and to stop on any dis-
played frequency.
When the “SCAN ” button is pressed for
automatic tuning, stations are scanned in
the direction of low frequencies to high fre-
quencies only.
Automatic tuning may not function proper-
ly if the station reception is weakened by
distance from the station or proximity to
tall buildings and hills.
Selecting preset stations
Presetting a station with a “Preset ” button
(5) allows you to select that station in a
single operation. Up to six AM, FM1 and
FM2 stations each may be preset.
How to preset stations
1. Press the “FM/AM ” selection button to
select AM, FM1 or FM2 reception.
2. Press the “SCAN ” button (1) or tune
the radio manually until the desired station
frequency is displayed.
3. Press one of the “Preset ” buttons (5)
for at least 2 seconds to store the fre-
quency. The frequency of the station will
flash once on the display at this time. If the
button is pressed for less than 2 seconds,
the preceding selection will remain in
memory.
NOTE
If the connection between the radio
and battery is broken for any reason
such as vehicle maintenance or radio
removal, all stations stored in the pre-
set buttons are cleared. If this occurs,
it is necessary to reset the preset but-
tons.
If a cell phone is placed near the ra-
dio, it may cause the radio to emit
noise when it receives calls. This noise
does not indicate a radio fault.

for at least 1.5 seconds to store the fre-
quency. The frequency of the station will
flash once on the display at this time. If the
button is pressed for less than 1.5 sec-
onds, the preceding selection will remain
in memory.

Starting the engine
Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and acces-
sories.
3. Press the clutch pedal to the floor and
shift the shift lever into neutral. Hold the
clutch pedal to the floor while starting the
engine.
The starter motor will only operate when
the clutch pedal is pressed fully to the
floor.
4. Turn the ignition switch to the “ON ” po-
sition and check the operation of the warn-
ing and indicator lights. Refer to the“ Warning and indicator lights ” section
(chapter 3).
5. Turn the ignition switch to the “START ”
position without depressing the accelera-
tor pedal. Release the key immediately af-
ter the engine has started. If the engine does not start, try the follow-
ing.
1) Turn the ignition switch to the “OFF ”
position and wait for at least 10 sec-
onds. After checking that the parking
brake is firmly set, turn the ignition
switch to the “START ” position while de-
pressing the accelerator pedal slightly
(approximately a quarter of the full
stroke). Release the accelerator pedal
as soon as the engine starts.
2) If this fails to start the engine, turn the
ignition switch back to the “OFF ” posi-
tion and wait for at least 10 seconds.
Then fully depress the accelerator ped-
al and turn the ignition switch to the“ START ” position. If the engine starts,
quickly release the accelerator pedal.
3) If this fails to start the engine, turn the
ignition switch again to the “OFF ” posi-
tion. After waiting for 10 seconds or
longer, turn the ignition switch to the“ START ” position without depressing
the accelerator pedal.
4) If the engine still refuses to start, con-
tact your nearest SUBARU dealer for
assistance.
6. Confirm that all warning and indicator
lights have gone off after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the en-
gine warms up.
NOTE
The engine may be difficult to start
when the battery has been disconnect-
ed and reconnected (for maintenance
or other purposes). This difficulty is
caused by the electronically controlled
throttle ’s self-diagnosis function. To
overcome it, keep the ignition switch in
the “ON ” position for approximately 10
seconds before starting the engine.
