Starting and operating
As additional guidance, only use fuels suited for your
vehicle as explained below.y
Fuel should be unleaded and have an octane rating
no lower than that specified in this manual.y Methanol (methyl or wood alcohol) is sometimes
mixed with unleaded gasoline. Methanol can be used
in your vehicle ONLY if it does not exceed 5% of the
fuel mixture AND if it is accompanied by sufficient
quantities of the proper cosolvents and corrosion in-
hibitors required to prevent damage to the fuel system.
Do not use fuel containing methanol EXCEPT under
these conditions. y If undesirable driveability problems are experienced
and you suspect they may be fuel related, try a differ-
ent brand of gasoline before seeking service at your
SUBARU dealer. y Fuel system damage or driveability problems which
result from the use of improper fuel are not covered
under the SUBARU Limited Warranty.
Do not let fuel spill on the exterior surfaces of
the vehicle. Fuels containing alcohol may
cause paint damage, which is not covered un-
der the SUBARU Limited Warranty. „

weather, which may cause injury.
3. Stop filling the tank after the fuel filler pump auto-
matically stops. Do not add any more fuel.
4. Put the cap back on, turn it clockwise until you hear
a clicking noise. Be certain not to catch the tether un-
der the cap while tightening.
5. Close the fuel filler lid completely.
If you spill any fuel on the painted surface, rinse it off
immediately. Otherwise, the painted surface could be
damaged.
NOTE
If the fuel filler cap is not tightened until it clicks or
if the tether is caught under the cap, the CHECK
ENGINE warning light may come on. Refer to the
“Warning and indicator lights” section located in
chapter 3.
y Never add any cleaning agents to the fuel
tank. The addition of a cleaning agent may
cause damage to the fuel system. y Make sure that the cap is tightened until it
clicks to prevent fuel spillage in the event of an
accident. y
Do not let fuel spill on the exterior surfaces of
the vehicle.
Fuels may cause paint damage, which is not
covered under the SUBARU Limited Warranty. y Always use a genuine SUBARU fuel filler cap.
If you use the wrong cap, it may not fit or have
proper venting, and your fuel tank and emis-
sion control system might be damaged.

Preparing to drive
You should perform the following checks and adjust-
ments every day before you start driving.
1. Check that all windows, mirrors, and lights are
clean and unobstructed.
2. Check the appearance and condition of the tires.
Also check tires for proper inflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood, trunk and rear gate are fully
closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside and outside mir-
rors.
7. Fasten your seatbelt. Check that your passengers
have fastened their seatbelts.
8. Check the operation of the warning and indicator
lights when the ignition switch is turned to the “ON” po- sition.
9. Check the gauges, indicator and warning lights af-
ter starting the engine.
NOTE
Engine oil, engine coolant, brake fluid, washer flu-
id and other fluid levels should be checked daily,
weekly or at fuel stops.
Starting the engine
Do not operate the starter motor continuously
for more than ten seconds. If the engine fails to
start after operating the starter for five to ten
seconds, wait for ten seconds or more before
trying again.
„ Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
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” position and
check the operation of the warning 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 accelerator pedal. Release
the key immediately after the engine has started.

7-10
Starting and operating
If the engine does not start, try the following:
1) Turn the ignition switch to the “OFF” position and
wait for at least 10 seconds. After checking that the
parking brake is firmly set, turn the ignition switch to
the “ON” position while depressing the accelerator
pedal slightly (about a quarter of the full stroke). Re-
lease 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” position and wait for at
least 10 seconds. Then fully depress the accelerator
pedal and turn the ignition switch to the “START”
position. If the engine starts, quickly release the ac-
celerator pedal.
3) If this fails to start the engine, turn the ignition
switch again to the “OFF” position. After waiting for
10 seconds or longer, turn the ignition switch to the
“START” position without depressing the accelera-
tor pedal.
4) If the engine still refuses to start, contact 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 automatically lowers the idle speed as the en-
gine warms up. „
Automatic transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and accessories.
3. Shift the selector lever to the “P” or “N” position
(preferably “P” position).
The starter motor will only operate when the select le-
ver is at the “P” or “N” position.
4. Turn the ignition switch to the “ON” position and
check the operation of the warning 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 accelerator pedal. Release
the key immediately after the engine has started.
If the engine does not start, try the following: 1) Turn the ignition switch to the “OFF” position and
wait for at least 10 seconds. After checking that the

3) If this fails to start the engine, turn the ignition
switch again to the “OFF” position. After waiting for
10 seconds or longer, turn the ignition switch to the
“START” position without depressing the accelera-
tor pedal.
4) If the engine still refuses to start, contact your
nearest SUBARU dealer for assistance.
6. Confirm that all warning and indicator lights have
gone out after the engine has started. The fuel injec-
tion system automatically lowers the idle speed as the
engine warms up.
While the engine is warming up, make sure that the
selector lever is at the “P” or “N” position and that the
parking brake is applied.
If you restart the engine while the vehicle is
moving, shift the selector lever into the “N” po-sition. Do not attempt to place the selector lever
of a moving vehicle into the “P” position.
Stopping the engine
The ignition switch should be turned off only when the
engine is idling.
Do not stop the engine when the vehicle is mov-
ing. This will cause loss of power to the power
steering and the brake booster, making steer-
ing and braking more difficult. It could also re-
sult in accidental activation of the “LOCK” po-
sition on the ignition switch, causing the steer-
ing wheel to lock.

the transmission to try shifting into reverse
when the vehicle is moving.
„ Shifting speeds
T Recommended shifting speeds
The best compromise between fuel economy and ve-
hicle performance during normal driving is ensured by
shifting up at the speeds listed in the following table. T
Maximum allowable speeds
The following tables show the maximum speeds that
are possible with each different gear. The tachome-
ter’s needle will enter the red area if these speeds are
exceeded.
With the exception of cases where sudden accelera-
tion is required, the vehicle should not be driven with
the tachometer’s needle inside the red area. Failure to
observe this precaution can lead to excessive engine
wear and poor fuel economy.
When shifting down a gear, ensure that the ve-
hicle is not travelling at a speed exceeding the
Maximum Allowable Speed for the gear which
is about to be selected. Failure to observe this
precaution can lead to engine over-revving and

Manual transmission – 5 speeds (ex-
cept WRX-STi)
The manual transmission is a fully synchromeshed, 5-
forward-speed and 1-reverse-speed transmission.
The shift pattern is shown on the shift lever knob.
When shifting from 5th gear to reverse gear, first re-
turn the shift lever to the neutral position then shift into
reverse gear.
To change gears, fully depress the clutch pedal, move
the shift lever, and gradually let up on the clutch pedal.
If it is difficult to shift into gear, put the transmission in
neutral, release the clutch pedal momentarily, and then try again.
Do not drive the vehicle with the clutch disen-
gaged (i.e., when the clutch pedal is depressed)
or with the shift lever in the neutral position.
Engine braking has no effect in either of these
conditions and the risk of an accident is conse-
quently increased.
Shift into reverse ONLY when the vehicle has
completely stopped. It may cause damage to
the transmission to try shifting into reverse
when the vehicle is moving.
