Operating tips for heater and
air conditioner „Cleaning ventilator grille
Always keep the front ventilator inlet grille
free of snow, leaves, or other obstructions
to ensure efficient heating and defrosting.
Since the condenser is located in front of
the radiator, this area should be kept
clean because cooling performance is im-
paired by any accumulation of insects and
leaves on the condenser. „ Efficient cooling after parking
in direct sunlight
After parking in direct sunlight, drive with
the windows open for a few minutes to al- low outside air to circulate into the heated
interior. This results in quicker cooling by
the air conditioner. Keep the windows
closed during the operation of the air con-
ditioner for maximum cooling efficiency. „
Lubrication oil circulation in
the refrigerant circuit
Operate the air conditioner compressor at
a low engine speed (at idle or low driving
speeds) a few minutes each month during
the off-season to circulate its oil. „ Checking air conditioning
system before summer sea-son
Check the air conditioner unit for refriger-
ant leaks, hose conditions, and proper op-
eration each spring. Have your SUBARU
dealer perform this check. „ Cooling and dehumidifying in
high humidity and low tem-
perature weather condition
Under certain weather conditions (high
relative humidity, low temperatures, etc.)
a small amount of water vapor emission
from the air outlets may be noticed. This
condition is normal and does not indicate any problem with the air conditioning sys-
tem. „
Air conditioner compressor
shut-off when engine is
heavily loaded
To improve acceleration and gas mileage,
the air conditioner compressor is de-
signed to temporarily shut off during air
conditioner operation whenever the accel-
erator is fully depressed such as during
rapid acceleration or when driving on a
steep upgrade. „ Refrigerant for your climate
control system
Your air conditioner uses ozone friendly
refrigerant HFC134a. Therefore, the
method of adding, changing or checking
the refrigerant is diffe rent from the method
for CFC12 (freon). Consult your SUBARU
dealer for service. Repairs needed as a
result of using the wrong refrigerant are
not covered under warranty.

Starting and operating 7-7
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 li ght trucks. Over 30
states plus the Distr ict of Columbia have
implemented the OBD system inspection. y The inspection of the OBD system con-
sists of a visual operational check of the “ CHECK ENGINE ” warning light/malfunc-
tion indicator lamp (MIL) and an examina-
tion 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, trunk (Sedan)
and rear gate (Station 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.

Gearshifts can be performed using the se-
lector lever.
Using the selector lever
Shift to the next-higher gear by briefly
pushing the selector
lever toward the “+”
end of the manual gate.
Shift to the next-lower gear by briefly pull-
ing the selector lever toward the “–” end of
the manual gate.
NOTE
Please read the following points care-
fully and bear them in mind when using
the manual mode.y The transmission does not automati-
cally shift up in the manual mode. Per-
form gearshifts in accordance with
road conditions so that the tachometer
needle does not enter the red zone. If the engine speed reaches a predeter-
mined level, a fuel-cut function will op-
erate. Shift up if this happens.y
If you attempt to sh ift down when the
engine speed is too high, i.e., when a
downshift would push the tachometer
needle beyond the red zone, beeps will
be emitted to warn you that the down-
shift is not possible. y If you attempt to shift up when the
vehicle speed is too low, the transmis-
sion will not respond.y You can perform a skip-shift (for ex-
ample, from 4th to 2nd) by operating
the selector lever twice in rapid suc-
cession. y The transmission automatically se-
lects 1st gear when the vehicle stops moving. y If the temperature of the automatic
transmission fluid becomes too high,
the “AT OIL TEMP” warning light will
come on and upshifts to 4th gear will
not be possible. Immediately stop the
vehicle in a safe place and let the en-
gine idle until the warning light goes off. „
Maximum speeds
The following tables show the maximum
speeds that are possible with each differ-
ent gear.
When down shifting, it is important to con-
firm that the current vehicle speed is not in
excess of the Maximum Allowable Speed
of the gear which is about to be selected.
700111
When down shifting, ensure that the
vehicle 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 this in turn can result in
engine damage.
In addition, sudden application of
engine braking caused by down
shifting when the vehicle is travel-
ling on a slippery surface can lead to
wheel locking; as a consequence,
control of the vehicle may be lost
and the risk of an accident in-
creased.

ground from under your tires, resulting in
possible loss of traction and even vehicle
rollover.y
Always check your brakes for effective-
ness immediately after driving in sand,
mud or water. Do this by driving slowly
and stepping on the brake pedal. Repeat
that process several times to dry out the
brake discs and brake pads.y Do not drive or park over or near flam-
mable materials such as dry grass or fall-
en leaves, as they may burn easily. The
exhaust system is very hot while the en-
gine is running and right after engine
stops. This could create a fire hazard.y After driving through tall grass, mud,
rocks, sand, rivers, etc., check that there
is no grass, bush, paper, rags, stones,
sand, etc. adhering to or trapped on the
underbody. Clear off any such matter from
the underbody. If the vehicle is used with
these materials trapped or adhering to the
underbody, a mechanical breakdown or
fire could occur. y Secure all cargo carried inside the vehi-
cle and make certain that it is not piled higher than the seatbacks. During sudden
stops or jolts, unsecured cargo could be
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. y When the road surface is extremely
slippery, 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 vehi cle with tires larg-
er than those specified in this manual. 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. y Frequent driving of an AWD vehicle un-
der hard-driving condit ions 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.
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.

sary, use 1st gear) in order to utilize the
engine braking effect and prevent over-
heating of your vehicle’s brakes. Do not
make sudden downshifts. yWhen driving uphill in hot weather, the
air conditioner may turn off automatically
to protect the engine from overheating. y When driving uphill in hot weather, pay
attention to the water temperature gauge
pointer (for all vehicles) and AT OIL TEMP
warning light (for AT vehicles) since the
engine and transmission are relatively
prone to overheating under these condi-
tions. If the water temperature gauge
pointer approaches the OVERHEAT zone
or the AT OIL TEMP warning light illumi-
nates, immediately switch off the air con-
ditioner and stop the vehicle at the nearest
safe place. Refer to the “Engine overheat-
ing” section in chapter 9, and “Warning
and indicator lights” section in chapter 3.
NOTE
With AT vehicles, the temperature of
engine coolant is less likely to rise to
the OVERHEAT zone in the “D” posi-
tion than in the manual mode position. y If your vehicle has an automatic trans-
mission, avoid using the accelerator pedal
to stay stationary on an uphill slope in-
stead of using the parking brake or foot
brake. That may cause the transmission fluid to overheat. T
Parking on a grade
Always block the wheels under both vehi-
cle and trailer when parking. Apply the
parking brake firmly. You should not park
on a hill or slope. But if parking on a hill or
slope cannot be avoided, you should take
the following steps:
1. Apply the brakes and hold the pedal
down.
2. Have someone place wheel blocks un-
der both the vehicle and trailer wheels.
3. When the wheel blocks are in place, re-
lease the regular brakes slowly until the
blocks absorb the load.
4. Apply the regular brakes and then ap-
ply the parking brake; slowly release the
regular brakes.
5. Shift into 1st or reverse gear (manual
transmission) or “P” (automatic transmis-
sion) and shut off the engine.

9-8 In case of emergency
10.Remove the wheel nuts and the flat tire.
11.Before putting the spare tire on, clean
the mounting surface of the wheel and
hub with a cloth.
12.Put on the spare tire. Replace the wheel nuts. Tighten them by hand.
13.Turn the jack handle counterclockwise
to lower the vehicle.
14.Use the wheel nut wrench to securely
tighten the wheel nut
s to the specified
torque, following the tightening order in
the illustration.
The torque for tightening the nuts is 74 to
89 lbf·ft (100 to 120 N·m, 10 to 12 kgf·m).
This torque is equivalent to applying ap- proximately 88 to 110 lbs (40 to 50 kg) at
the top of the wheel
nut wrench. Never
use your foot on the wheel nut wrench or
a pipe extension on the wrench because
you may exceed the specified torque.
Have the wheel nut torque checked at the
nearest automotive service facility.
15.Store the flat tire in the spare tire com- partment.
Put the spacer and tighten the attaching
bolt firmly.
Also store the jack and jack handle in their
storage locations.

Do not use oil or grease on the
wheel studs or nuts when the spare
tire is installed. This could cause the
nuts to become loose and lead to an
accident.
