which are designed for 12V DC.
The maximum power rating of an
appliance that can be connected
varies among outlets as shown in
the following. Do not use an
appliance which exceeds the in-
dicated wattage for each outlet.
Outlet beside front pocket: 80W
or less
Outlet in cargo area: 120W or less
When using appliances con-
nected to two outlets simulta-
neously, the total power con-
sumed by them must not exceed
120W. Overloading the accessory
power outlet can cause a short
circuit. Do not use dual adapters
or more than one electrical appli-ance.
. If the plug on your electric appli-
ance is either too loose or too
tight for the accessory power
outlet, this can result in a poor
contact or cause the plug to get
stuck. Only use plugs that fit
properly.
. Use of an electric appliance in the
accessory power outlet for a long
period of time while the engine is
not running can cause battery discharge.
. Before driving your vehicle, make
sure that the plug and the cord
on your electrical appliance will
not interfere with your shifting
gears and operating the accel-
erator and brake pedals. If they
do, do not use the electrical
appliance while driving.
& Use with a cigarette lighter
(Canada only, if equipped)
To use the accessory power outlet beside
the front pocket as a cigarette lighter
socket, purchase the cigarette lighter plug,
which is an optional accessory.
A cigarette lighter plug is available from your SUBARU dealer.
The cigarette lighter operates only when
the ignition switch is in the
“ON ”or “Acc ”
position.
To use the cigarette lighter, push in the
knob and wait a few moments. It will
automatically spring up when ready foruse.
WARNING
To avoid being burned, never grasp
the lighter by the end with the
heating element. Doing so could
result in injury and could also
damage the heating element.
CAUTION
. Do not hold the lighter pushed in,
because it will overheat.
. The electrical power socket lo-
cated on the lower part of the
instrument panel is originally de-
signed to use a genuine SUBARU
cigarette lighter plug. Do not use
a non-genuine cigarette lighter
plug in the socket. Doing so
may cause a short-circuit and
overheating, resulting in a fire.
. If the socket is ever used for a Interior equipment

CAUTION
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.
The EPA has issued regulations for
inspecting the On-Board Diagnostic
(OBD) system as part of the state emis-
sions inspection. The OBD system is
designed to detect engine and transmis-
sion problems that might cause vehicle
emissions to exceed 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. . The inspection of the OBD system
consists of a visual operational check of the “CHECK ENGINE ”warning light/mal-
function indicator lamp (MIL) and an
examination of the OBD system with an
electronic scan tool while the engine isrunning. . Avehicle
passes the OBD system
inspection if proper the “CHECK ENGINE ”
warning light/MIL illumination is observed,
there is nostored diagnostic trouble codes, and the OBD system readiness
monitors are complete. .
A vehicle
fails the OBD inspection if the
“ CHECK ENGINE ”warning light/MIL is
not properly operating or there are one or
more diagnostic trouble codes stored in
the vehicle ’s computer with the “CHECK
ENGINE ”warning light/MIL illuminated.
. 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. . 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 properinflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood, trunk (Sedan)
and rear gate (Wagon) 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
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.
& Manual transmission vehicle
1. Apply the parking brake.
2. Turn off unnecessary lights and ac- cessories.
3. Press the clutch pedal to the floor and
shift the shift lever into neutral. Hold the
clutch pedal to the floor while starting theengine.
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 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 gone off after the engine has
started. The fuel injection system auto- matically lowers the idle speed as the
engine warms up.
NOTE
The engine may be difficult to start
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

CAUTION
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. Stopping the engine
The 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.

The driver ’s control center differential
allows you to freely change the degree
of limitation of the differential action
(limited slip differential (LSD) torque) of
your vehicle ’s center differential.
By using the center differential control dial,
you can set an initial LSD torque to match
the road surface conditions, driving con-
ditions and your driving style.
1) LSD torque
2) Traction torque
A) Initial LSD torque (adjustable)
B) Mechanical LSD torque &
Auto mode
In the auto mode, the system estimates
the driving and road conditions using
signals from the wheel speed sensor,
throttle position sensor, steering angle
sensor and brake switch, etc. According
to the result, it electronically and auto-
matically controls the degree of limitation
of the differential action (LSD torque) to
optimize the differential action of the
center differential. When the ignition
switch is turned ON, the “AUTO ”indicator
light in the combination meter comes on.
The system can be switched to a manual mode. &
Manual mode
In the manual mode, you can use the
center differential control dial to adjust the
initial LSD torque as desired. When this
mode is selected, the “AUTO ”indicator

To shift the selector lever from the“P ”
position to any other position, you have to
depress the brake pedal fully when the
ignition switch is in the “ON ”position. This
prevents the vehicle from lurching when it
is started.
If the shift lever does not move from the “ P ” position with the brake pedal de-
pressed, refer to the “Shift lock release ”
section in this chapter. ! R (Reverse)
This position is for backing the vehicle.
To shift from the “N ” to “R ” position, first
stop the vehicle completely then move the
lever to the “R ”position.
! N (Neutral)
This position is for restarting a stalledengine.
In this position the wheels and transmis-
sion are not locked. In this position, the
transmission is neutral; the vehicle will roll
freely, even on the slightest incline unless
the parking brake or foot brake is on.
Avoid coasting with the transmission neutral.
During coasting, there is no engine brak-
ing effect. NOTE
If you stop the engine with the selector
lever in the
“N ” position, move the
selector lever to the “P ” position
immediately. Otherwise, you may find
that the selector lever soon cannot be
moved to the “P ” position. If you find
that the selector lever cannot be moved
from the “N ” position to the “P ” posi-
tion, turn the ignition switch to the“ ON ”position and try again.
WARNING
Do not drive the vehicle with the
selector lever in the “N ” (neutral)
position. Engine braking has no
effect in this condition and the risk
of an accident is consequently in-creased.
! D (Drive)
This position is for normal driving.
The transmission automatically shifts into
a suitable gear from 1st to 4th according to
the vehicle speed and the acceleration
you require.
When more acceleration is required in this
position, press the accelerator pedal fully
to the floor and hold that position. The
transmission will automatically downshift to 3rd, 2nd or 1st gear. When you release
the pedal, the transmission will return to
the original gear position. !
While climbing a grade
When driving up hill, undesired upshift to
4th gear is prevented from taking place
when the accelerator pedal is released.
This minimizes the chances of subse-
quent downshifting to a lower gear when
accelerating again. This prevents re-
peated upshifting and downshifting result-
ing in a smoother operation of the vehicle. NOTE
The transmission may downshift to 2nd
or 1st gear, depending on the way the
accelerator pedal is pressed to accel-
erate the vehicle again. ! While going down a hill
When descending a steep hill, depressing
the brake pedal will cause the transmis-
sion to downshift to 3rd gear, thus apply-
ing engine braking. Reacceleration for a
short time will cause the transmission to
upshift normally. NOTE
In some cases, depressing the brake
pedal on a downhill grade does not
result in an automatic downshift to 3rd
gear. This can happen when the auto- Starting and operating

.Always set the parking brake when
parking your vehicle. Do not hold the
vehicle with only the transmission. . Do not keep the vehicle in a stationary
position on an uphill grade by using the “ D ”, “3 ”, “2 ”,or “1 ” position. Use the brake
instead.
The engine may, on rare occasions, knock
when the vehicle rapidly accelerates or
rapidly pulls away from a standstill. This
phenomenon is not an indication of a
problem in your vehicle.
& Shift lock release
If the selector lever does not move fromthe “P ” position with the brake pedal
depressed and the ignition switch in the“ ON ”position, perform the following steps:
To override the shift lock:
1. Set the parking brake and stop the engine.
2. Take out the screwdriver from the tool bag.
3. Remove the cover by prying on the
edge with the screwdriver.
4. Insert the screwdriver into the hole.
5. Push down on the screwdriver and
move the selector lever from the “P ”to the
“ N ”position.
6. Remove the screwdriver from the hole.

. When driving on badly surfaced
roads, gravel roads, icy roads, or
over deep newly fallen snow,
stopping distances may be long-
er for a vehicle with the ABS
system than one without. When
driving under these conditions,
therefore, reduce your speed and
leave ample distance from othervehicles.
. 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
operation of the ABS system.
& ABS system self-check
Just after the vehicle is started, you may
feel on the brake pedal a vibration similar
to when the ABS operates, and you may
also hear the sound of the ABS working
from the engine compartment. This is
caused by an automatic functional test of
the ABS system being carried out and
does not indicate any abnormal condition. &
ABS warning light
The ABS warning light comes on when the
ignition switch is turned to the “ON ”
position and goes out after approximately
2 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.
CAUTION
If the warning light behaves as
follows, 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. . The warning light does not come
on when the ignition switch is
turned to the “ON ”position.
. The warning light comes on when
the ignition switch is turned tothe “ON ”position, but it does not
go out even when the vehicle
speed exceeds approximately 8
mph (12 km/h).
. 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.
NOTE
If the warning light behavior is as
described in the following, the ABS
system may be considered normal. . The warning light comes on right

and other obstructions on the
ground when parking. The under-
spoilers could be damaged by con-
tact with them. Cruise control
Cruise control enables you to maintain a
constant vehicle speed without holding
your foot on the accelerator pedal and it is
operative when the vehicle speed is 25
mph (40 km/h) or more. Make sure the
main switch is turned
“OFF ”when the
cruise control is not in use to avoid
unintentionally setting the cruise control.
NOTE
If you move the cruise control lever or
press the main switch button while
turning the ignition switch “ON ”, the
cruise control function is deactivated
and the “CRUISE ”indicator light
flashes. To reactivate the cruise control
function, turn the ignition switch back
to the “Acc ”or “LOCK ”position, and
then turn it again to the “ON ”position.
WARNING
Do not use the cruise control under
any of the following conditions. This
may cause loss of vehicle control: . driving up or down a steep grade
. driving on slippery or winding
roads
. driving in heavy traffic &
To set cruise control
1. Push the main switch button.
The “”indicator light on the combina-
tion meter will come on.
2. Depress the accelerator pedal until the

vehicle reaches the desired speed.
3. Push the control lever downward in the “SET/COAST ”direction and release it.
Then release the accelerator pedal.
At this time, the “”indicator light is
illuminated in the combination meter. The vehicle will maintain the desired speed.
Vehicle speed can be temporarily in-
creased while driving with the cruise
control activated. Simply depress the
accelerator pedal to accelerate the vehi-
cle. When the accelerator pedal is re-
leased, the vehicle will return to and
maintain the previous cruising speed.
& To temporarily cancel the
cruise control
There are five ways to cancel the cruise
control temporarily:
. Pull the control lever in the “CANCEL ”
direction. . Depress the brake pedal.
. Depress the clutch pedal (manual transmission vehicles only)..
Shift the selector lever into the “N ”
position (automatic transmission vehicles only). . Shift the shift lever into neutral position
(manual transmission vehicles only). The “
”indicator light in the combination
meter goes off when the cruise control is canceled.
To resume the cruise control after it has
been temporarily canceled and with vehi-
cle speed of approximately 20 mph (32
km/h) or more, push the control lever
upward in the “RES/ACC ”direction to
return to the original cruising speed auto-
matically. The “
”indicator light in the combination
meter will automatically come on at this time. & To turn off the cruise control
There are two ways to turn off the cruise control: . Push the main switch again.
. Turn the ignition switch to the “Acc ”or
