whenever the low fuel warning
light illuminates. Engine misfires
as a result of an empty tank
could cause damage to the en-
gine.
State emission testing (U.S.
only)
WARNING
Testing of an All-Wheel Drive model
must NEVER be performed on a
single two-wheel dynamometer. At-
tempting to do so will result in
uncontrolled vehicle movement and
may cause an accident or injuries to
persons nearby.
CAUTION
. At state inspection time, remem-
ber to tell your inspection or
service station in advance not to
place your SUBARU AWD vehicle
on a two-wheel dynamometer.
Otherwise, serious transmission
damage will result.
. Resultant vehicle damage due to
improper testing is not covered
under the SUBARU Limited War-
ranty and is the responsibility of
the state inspection program or
its contractors or licensees.
California and a number of federal states
have Inspection/Maintenance programs to inspect your vehicle
’s emission control
system. If your vehicle does not pass this
test, some states may deny renewal of
your vehicle’ s registration.
Your vehicle is equipped with a computer
that monitors the performance of the
engine’ s emission control system. Certi-
fied emission inspectors will inspect the
On-Board Diagnostic (OBDII) system as
part of the state emission inspection
process. The OBDII system is designed
to detect engine and transmission pro-
blems that might cause the vehicle emis-
sions to exceed allowable limits. OBDII
inspections apply to all 1996 model year
and newer passenger cars and trucks.
Over 30 states plus the District of Colum-
bia have implemented emission inspec-
tion of the OBDII system.
. The inspection of the OBDII system
consists of a visual operational check of
the “CHECK ENGINE ”warning light/mal-
function indicator light (MIL) and an
examination of the OBDII system with an
electronic scan tool.
. A vehicle
passes the OBDII system
inspection if proper operation of the
“CHECK ENGINE ”warning light is ob-
served, there are no stored diagnostic
trouble codes, and the OBDII readiness
monitors are all complete.Starting and operating

Starting and operating
. A vehicle
fails the OBDII inspection if
the “CHECK ENGINE ”warning light is not
properly operating (light is illuminated or is
not working due to a burned out bulb) or
there is one or more diagnostic trouble
codes stored in the vehicle’ s computer.
. A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBDII system readiness monitors “NOT
READY ”is greater than one. If the
vehicle’ s battery has been recently re-
placed or disconnected, the OBDII system
inspection may indicate that the vehicle is
not ready for the emission test. Under this
condition, the vehicle driver should be
instructed to drive his/her vehicle for a few
days to reset the readiness monitors and
return for an emission re-inspection.
. Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Some states still use dynamometers in
their emission inspection program. A
dynamometer is a treadmill or roller-like
testing device that allows your vehicle ’s
wheels to turn while the vehicle remains in
one place. Prior to your vehicle being put
on a dynamometer, tell your emission
inspector
not to place your SUBARU
AWD vehicle on a two-wheel dynam-
ometer. Otherwise, serious transmis-
sion damage will result. The U.S. Environmental Protection
Agency (EPA) and states using two-wheel
dynamometers in their emission testing
program have EXEMPTED SUBARU
AWD vehicles from the portion of the
testing program that involves a two-wheel
dynamometer. There are some states that
use four-wheel dynamometers in their
testing program. When properly used, this
equipment should not damage a SUBARU
AWD vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
Preparing to driveYou should perform the following checks
and adjustments 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 (4-door)
and rear gate (5-door) are fully closed.
5. Check the adjustment of the seat.
6. Check the adjustment of the inside
and outside mirrors.
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”position.
9. Check the gauges, indicator and warn-
ing lights after starting the engine.NOTEEngine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.

Starting the engine
CAUTION
Do not operate the starter motor
continuously for more than 10 sec-
onds. If the engine fails to start after
operating the starter for 5 to 10
seconds, wait for 10 seconds or
more before trying again.NOTEIt may be difficult to start the engine
when the battery has been discon-
nected and reconnected (for mainte-
nance or other purposes). This diffi-
culty 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.
1. Apply the parking brake.
2. Turn off unnecessary lights and ac-
cessories.
3. Depress 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 depressed 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
“Warning and indicator lights ”F 3-12.
5. Turn the ignition switch to the “START”
position without depressing the accelera-
tor 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
parking brake is firmly set, turn the
ignition switch to the “START”position
while depressing 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”
position and wait for at least 10
seconds. Then fully depress the accel-
erator pedal 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”
position. 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,
contact your nearest SUBARU dealer
for assistance.
6. Confirm that all warning and indicator
lights have turned off after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the
engine warms up.

Starting and operating
Stopping the engineThe ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
WARNING
Do not stop the engine when the
vehicle is moving. This will cause
loss of power to the power steering
and the brake booster, making steer-
ing and braking more difficult. It
could also result in accidental acti-
vation of the “LOCK ”position on the
ignition switch, causing the steering
wheel to lock.
Remote engine start system
(dealer option)
WARNING
. Do not start the engine using the
remote start system in an en-
closed environment (e.g., in a
closed garage). Prolonged opera-
tion of a motor vehicle in an
enclosed environment can cause
a harmful build-up of Carbon
Monoxide. Carbon Monoxide is
harmful to your health. Exposure
to high levels of Carbon Monox-
ide can cause headaches, dizzi-
ness or in extreme cases uncon-
sciousness and/or death.
. Before performing any servicing
of the vehicle, temporarily place
the remote engine start system in
service mode to prevent the
system from unexpectedly start-
ing the engine.
& Starting your vehicleThe remote engine start system is acti-
vated by pressing the “
”button twice
within 3 seconds on your remote engine
start transmitter. The system will check
certain pre-conditions before starting, and
if all safety parameters are correct, the
engine will start within 5 seconds. While
the vehicle is operating via remote engine
start, the vehicle ’s power window features
will be disabled. Also, the system has a

& System maintenance! Changing the batteries
CAUTION
.Do not let dust, oil or water get on
or in the remote engine start
transmitter when replacing the
battery.
. Be careful not to damage the
printed circuit board in the re-
mote engine start transmitter
when replacing the battery.
. Be careful not to allow children to
touch the battery and any re-
moved parts; children could
swallow them.
. There is a danger of explosion if

Black plate (263,1)

an incorrect replacement battery
is used. Replace only with the
same or equivalent type of bat-
tery.
. Batteries should not be exposed
to excessive heat such as sun-
shine, fire or the like.
The two 3-volt lithium batteries (model
CR-1220 ) supplied in your remote engine
start transmitter should last approximately
3 years, depending on usage. When the
batteries begin to weaken, you will notice
a decrease in range (distance from the
vehicle that your remote engine start
system operates). Follow the instructions
below to change the remote engine start
transmitter batteries.
1. Carefully pry the remote engine start
transmitter halves apart using a small flat-
head screwdriver.
2. Remove the circuit board from the
bottom half of the case and slide the white
plastic battery holder out from under the
battery tab releasing the batteries. Re-
move the old batteries and replace with
new ones. Be sure to observe the (+) sign
on the old batteries before removing them
to ensure that the new batteries are
inserted properly (battery “+”should be
pointed away from the transmitter circuit
board on both batteries).
3. Carefully snap the case halves back
together, then test the remote engine start
system.
