not damage an AWD SUBARU vehicle.
Under no circumstances should the rear
wheels be jacked off the ground, nor
should the driveshaft be disconnected for
state emission testing.
The EPA has issued regulations for in-
specting the On-Board Diagnostic (OBD)
system as part of the state emissions in-
spection. The OBD system is designed to
detect engine and transmission problems
that might cause vehicle emissions to ex-
ceed allowable limits. These inspections
apply to all 1996 model year and newer
passenger cars and light trucks. Over 30
states plus the District of Columbia have
implemented the OBD system inspection. yThe inspection of the OBD system con-
sists of a visual operational check of the
“CHECK ENGINE” warning light/mal-
function indicator lamp (MIL) and an ex-
amination of the OBD system with an
electronic scan tool while the engine is
running y A vehicle passes
the OBD system in-
spection if proper the “CHECK ENGINE”
warning light/MIL illumination is observed,
there is no stored diagnostic trouble
codes, and the OBD system readiness
monitors are complete. y A vehicle fails
the OBD inspection if the “CHECK ENGINE”
warning light/MIL is
not properly operating or there is one or
more diagnostic trouble codes stored in
vehicle’s computer with the “CHECK EN-
GINE” warning light/MIL illuminated.
y A state emission inspection may reject
(not pass or fail) a vehicle if the number of
OBD system readiness monitors “Not
Ready” is greater than one. Under this
condition, the vehicle operator should be
instructed to drive his/her vehicle for a few
days to set the monitors and return for an
emission re-inspection. y Owners of rejected or failing vehicles
should contact their SUBARU Dealer for
service.
Preparing to drive
You 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 infla-
tion.
3. Look under the vehicle for any sign of
leaks.
4. Check that the hood and rear gate 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.
NOTE
Engine oil, engine coolant, brake fluid,
washer fluid and other fluid levels
should be checked daily, weekly or at
fuel stops.

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
(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” 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. „ Automatic transmission vehi-

2. Turn off unnecessary lights and acces-
sories.
3. Shift the selector lever to the “P” or “N”
position (preferably “P” position).
The starter motor will only operate when
the select lever is at the “P” or “N” position.
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”

tor pedal. Release the key immediately af-
ter the engine has started.
If the engine does not start, try the follow-
ing.
Do not operate the starter motor
continuously for more than ten sec-
onds. If the engine fails to start after
operating the starter for five to ten
seconds, wait for ten seconds or
more before trying again.

7-8 Starting and operating
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
(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” 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 out after the engine has
started. The fuel injection system auto-
matically lowers the idle speed as the en-
gine 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.
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.
Stopping the engine
The ignition switch should be turned off
only when the vehicle is stopped and the
engine is idling.
If you restart the engine while the
vehicle is moving, shift the selector
lever into the “N” position. Do not
attempt to place the selector lever of
a moving vehicle into the “P” posi-
tion.
Do not stop the engine when the ve-
hicle is moving. This will cause loss
of power to the power steering and
the brake booster, making steering
and braking more difficult. It could
also result in accidental activation
of the “LOCK” position on the igni-
tion switch, causing the steering
wheel to lock.

Starting and operating 7-17
– CONTINUED –
The ABS system prevents the lock-up of
wheels which may occur during sudden
braking or braking on slippery road surfac-
es. This helps prevent the loss of steering
control and directional stability caused by
wheel lock-up.
When the ABS system is operating, you
may hear a chattering noise or feel a slight
vibration in the brake pedal. This is normal
when the ABS operates.
The ABS system will not operate when the
vehicle speed is below approximately 6
mph (10 km/h). „
ABS system self-check
You may feel a slight shock in the brake
pedal and hear the operating sound of
ABS from the engine compartment just af-
ter the vehicle is started. This is caused by
an automatic functional test of the ABS
system being carried out and does not in-
dicate any abnormal condition. „
ABS warning light
1) U.S.-spec. models
2) Canada-spec. models
The ABS warning light comes on when the
ignition switch is turned to the “ON” posi-
tion and goes out after approximately two
seconds.
This is an indication that the ABS system
is working properly.
When driving with an insufficient battery
voltage such as when the engine is jump
started, the ABS warning light may come
on. This is due to the low battery voltage
and does not indicate a malfunction.
When the battery becomes fully charged,
the light will go out.
NOTE
If the warning light behavior is as de-
scribed in the following, the ABS sys-
tem may be considered normal. y The warning light comes on right af-
ter the engine is started but goes out
y
When you feel the ABS system
operating, you should maintain
constant brake pedal pressure.
Do not pump the brake pedal
since doing so may defeat the op-
eration of the ABS system.

700333 If the warning light behaves as fol-
lows, the ABS system may not be
working properly.
When the warning light is on, the
ABS function shuts down; however,
the conventional brake system con-
tinues to operate normally. y
The warning light does not come
on when the ignition switch is
turned to the “ON” position.
y The warning light comes on when
the ignition switch is turned to the
“ON” position, but it does not go
out even when the vehicle speed
exceeds approximately 8 mph (12
km/h).
y The warning light comes on dur-
ing driving.
If these occur, have the ABS system
repaired at the first available oppor-
tunity by your SUBARU dealer.

motion may therefore become somewhat
harder to control.
If the brake system warning light and ABS
warning light illuminate simultaneously,
take the following steps:
1. Stop the vehicle in the nearest safe, flat
place.
2. Shut down the engine, then restart it.
3. Release the parking brake. If both
warning lights go out, the EBD system
may be faulty.
Drive carefully to the nearest SUBARU
dealer and have the system inspected.
4. If both warning lights come on again
and stay illuminated after the engine has
been restarted, shut down the engine
again, apply the parking brake, and check
the brake fluid level.
5. If the brake fluid level is not below the
“MIN” mark, the EBD system may be
faulty. Drive carefully to the nearest
SUBARU dealer and have the system in-
spected.
6. If the brake fluid level is below the
“MIN” mark, DO NOT drive the vehicle. In-
stead, have the vehicle towed to the near-
est SUBARU dealer for repair.
Parking your vehicle
y
Driving with the brake system
warning light on is dangerous.
This indicates your brake system
may not be working properly. If
the light remains on, have the
brakes inspected by a SUBARU
dealer immediately.
yIf at all in doubt about whether the
brakes are operating properly, do
not drive the vehicle. Have your
vehicle towed to the nearest SUB-
ARU dealer for repair.
yNever leave unattended children
or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent opera-
tion of the vehicle. Also, on hot or
sunny days, the temperature in a
closed vehicle could quickly be-
come high enough to cause se-
vere or possibly fatal injuries to
people.
yDo not park the vehicle over flam-
mable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.
yBe sure to stop the engine if you
take a nap in the vehicle. If engine
exhaust gas enters the passenger
compartment, occupants in the
vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.

thrown around in the vehicle and cause in-
jury. Do not pile heavy loads on the roof.
Those loads raise the vehicle’s center of
gravity and make it more prone to tip over. y
If you must rock the vehicle to free it
from sand or mud, depress the accelera-
tor pedal slightly and move the selector le-
ver back and forth between “D” and “R” re-
peatedly. Do not race the engine. For the
best possible traction, avoid spinning the
wheels when trying to free the vehicle.
When the road surface is extremely slip-
pery, you can obtain better traction by
starting the vehicle with the transmission
in 2nd than 1st (both for MT and AT). y Never equip your vehicle with tires larg-
er than those specified in this manual.y Frequent driving of an AWD vehicle un-
der hard-driving conditions such as rough
roads or off roads will necessitate more
frequent replacement of engine oil, brake
fluid and transmission oil than that speci-
fied in the maintenance schedule de-
scribed in the “Warranty and Maintenance
Booklet”.
Remember that damage done to your
SUBARU while operating it off-road and
not using common sense precautions
such as those listed above is not eligible
for warranty coverage.y Wash the vehicle’s underbody after off-
road driving. Suspension components are particularly prone to dirt buildup, so they
need to be washed thoroughly.
Winter driving „
Operation during cold weath- er
Carry some emergency equipment, such
as tire chains, a window scraper, a bag of
sand, flares, a small shovel, and jumper
cables.
Check the battery and cables. Cold tem-
peratures reduce battery capacity. The
battery must be in good condition to pro-
vide enough power for cold winter starts.
Use an engine oil of proper grade and vis-
cosity for cold weather. Heavy summer oil
will cause harder starting.

Connection of trailer lights to your vehi-
cle’s electrical system requires modifica-
tions to the vehicle’s lighting circuit to in-
crease its capacity and accommodate wir-
ing changes. To ensure the trailer lights
are connected properly, please consult
your SUBARU dealer. Check for proper
operation of the turn signals, the brake
lights and parking lights each time you
hitch up. T
Tires
Make sure that all the tires on your vehicle
are properly inflated to the pressure spec-
ified on the tire placard located on the driv-
er’s side center pillar.
Trailer tire condition, size, load rating and
proper inflation pressure should be in ac-
cordance with the trailer manufacturer’s
specifications. „
Trailer towing tips
TBefore starting out on a trip
y Check that the vehicle and vehicle-to-
hitch mounting are in good condition. If
any problems are apparent, do not tow the
trailer. y Check that the vehicle sits horizontally
with the trailer attached. If the vehicle is
tipped sharply up at the front and down at
the rear, check the total trailer weight,
GVW, GAWs and tongue load again, then
confirm that the load and its distribution
are acceptable. y Check that the tire pressures are cor-
rect. y Check that the vehicle and trailer are connected properly. Confirm that
– the trailer tongue is connected prop-
erly to the hitch ball.
– the trailer lights connector is connect-
ed properly and trailer’s brake lights illu-
minate when the vehicle’s brake pedal
is pressed, and that the trailer’s turn sig-
nal lights flash when the vehicle’s turn
signal lever is operated.
– the safety chains are connected prop-
erly.
– all cargo in the trailer is secured safe-
ty in position.
– the side mirrors provide a good rear-
ward field of view without a significant
blind spot.
y Sufficient time should be taken to learn
the “feel” of the vehicle/trailer combination
before starting out on a trip. In an area free
of traffic, practice turning, stopping and
backing up. T Driving with a trailer
y You should allow for considerably more
stopping distance when towing a trailer.
Avoid sudden braking because it may re-
sult in skidding or jackknifing and loss of
control. y Avoid abrupt starts and sudden acceler-
ations. If your vehicle has a manual trans-
mission, always start out in first gear and
release the clutch at moderate engine rev-
Never tow a trailer when the tempo-
rary spare tire is used. The tempo-
rary spare tire is not designed to
sustain the towing load. Use of the
temporary spare tire when towing
can result in failure of the spare tire
and/or less stability of the vehicle.
y Never exceed 45 mph (72 km/h)
when towing a trailer in hilly coun-
try on hot days.
y When towing a trailer, steering,
stability, stopping distance and
braking performance will be dif-
ferent from normal operation. For
safety’s sake, you should employ
extra caution when towing a trail-
er and you should never speed.
You should also keep the follow-
ing tips in mind:

11 - 1 0 Maintenance and service
The oil quantity indicated above is only a
guideline. The necessary quantity of oil
depends on the quantity of oil that has
been drained. The quantity of drained oil
differs slightly depending on the tempera-
ture of the oil and the time the oil is left
flowing out. After pouring oil into the en-
gine, therefore, you must use the dipstick
to confirm that the level is correct.
13.Start the engine and make sure that no
oil leaks appear around the filter’s rubber
seal.
14.Run the engine until it reaches the nor-
mal operating temperature. Then stop the
engine and wait a few minutes to allow the
oil drain back. Check the oil level again
and if necessary, add more engine oil. „Recommended grade and
viscosity
Oil grade:
ILSAC GF-4, which can be identified
with the ILSAC certification mark
(Starburst mark)
or API classification SM with the
words “ENERGY CONSERVING”
These recommended oil grades can be
identified by looking for either or both of
the following marks displayed on the oil
container. API Service label
1) Indicates the oil quality by API designa-
tions
2) Indicates the SAE oil viscosity grade
3) Indicates that the oil has fuel saving ca- pabilities ILSAC Certification Mark (Starburst
Mark)
In choosing an oil, you want the proper
quality and viscosity, as well as one that
will add to fuel economy. The following ta-
ble lists the recommended viscosities and
applicable temperatures.
When adding oil, different brands may be
used together as long as they are the
same API classification and SAE viscosity
as those recommended by SUBARU.
