cessitate more frequent replacement of engine oil,
brake fluid and transmission oil than that specified in
the maintenance schedule described in the “Warranty
and Maintenance Booklet”.
Remember that damage done to your Subaru while
operating it off-road and not using common sense pre-
cautions such as those listed above is not eligible for
warranty coverage.
Always maintain a safe driving speed accord-
ing to the road and weather conditions in order
to avoid having an accident on a sharp turn,
during sudden braking or under other similar
conditions. Always use the utmost care in driving – over-
confidence because you are driving an all
wheel drive vehicle could easily lead to a seri-
ous accident.
Winter driving Operation during cold weather
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 temperatures re-
duce battery capacity. The battery must be in good
condition to provide enough power for cold winterstarts.
Use an engine oil of proper grade and viscosity for
cold weather. Heavy summer oil will cause harder

starting.
Keep the door locks from freezing by squirting them
with deicer or glycerin.
Forcing a frozen door open may damage or separate
the rubber weather strips around the door. If the door
is frozen, use hot water to melt the ice, and afterwards
thoroughly wipe the water away.
Use a windshield washer fluid that contains an anti-
freeze solution. Do not use engine antifreeze or other
substitutes because they may damage the paint of the
vehicle.
Before driving your vehicle
Before entering the vehicle, remove any snow or ice
from your shoes because that could make the pedals
slippery and dangerous.
While warming up the vehicle before driving, check
that the accelerator pedal, brake pedal, and all other
controls operate smoothly.
Clear away ice and snow that has accumulated under
the fenders to avoid making steering difficult. During
severe winter driving, stop when and where it is safe
to do so and check under the fenders periodically.
Parkingincoldweather
Do not use the parking brake when parking for long
periods in cold weather since it could freeze in that po-
sition. Instead, observe the following:
1. Place the shift lever in “1” or “R” for manual trans-
mission vehicles, and in “P” for automatic transmission
vehicles.
2. Use tire stops under the tires to prevent the vehicle
from moving.
When the vehicle is parked in snow or when it snows,
raise the wiper blades off the glass to prevent damage
to them.
When the vehicle has been left parked after use on
roads heavily covered with snow, or has been left
parked during a snowstorm, icing may develop on the
brake system, which could cause poor braking action.
Check for snow or ice buildup on the suspension, disc
brakes and brake hoses underneath the vehicle.
If there is caked snow or ice, remove it, being careful
not to damage the disc brakes and brake hoses and
ABS harness.
Snow can trap dangerous exhaust gases under
your vehicle. Keep snow clear of the exhaust

ally.
When passing other vehicles, considerable dis-
tance is required because of the added weight and
length caused by attaching the trailer to your vehicle.
1) Left turn
2) Right turn
Backing up with a trailer is difficult and takes prac-
tice. When backing up with a trailer, never accelerate
or steer rapidly. When turning back, grip the bottom of
the steering wheel with one hand and turn it to the left
for a left turn, and turn it to the right for a right turn. If the ABS warning light illuminates while the vehicle
is in motion, stop towing the trailer and have repairs performed immediately by the nearest SUBARU deal- er.
Driving on grades
Before going down a steep hill, slow down and shift
into lower gear (if necessary, use 1st gear) in order to
utilize the engine braking effect and prevent overheat-
ing of your vehicle’s brakes. Do not make sudden
downshifts. When driving uphill in hot weather, the air condition-
er may turn off automatically to protect the engine from
overheating. 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 conditions. If the water tem-
perature gauge pointer approaches the OVERHEAT
zone or the AT OIL TEMP warning light illuminates,
immediately switch off the air conditioner and stop the
vehicle at the nearest safe place. Refer to the “Engine
overheating” section in chapter 9, and “Warning and
indicator lights” section in chapter 3. If your vehicle has an automatic transmission, avoid
using the accelerator pedal to stay stationary on an
uphill slope instead of using the parking brake or foot
brake. That may cause the transmission fluid to over-
heat. Also, if your vehicle is equipped with an automat-

ic transmission, avoid driving with the gear selector
lever in “D” when towing a heavy trailer to prevent fluid
overheating. A lower gear should be used. Parking on a grade
Always block the wheels under both vehicle 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 under both the
vehicle and trailer wheels.
3. When the wheel blocks are in place, release the
regular brakes slowly until the blocks absorb the load.
4. Apply the regular brakes and then apply the park-
ing brake; slowly release the regular brakes.
5. Shift into 1st or reverse gear (manual transmission)
or “P” (automatic transmi ssion) and shut off the en-
gine.

Maintenance and service
the materials in the vehicle may be hazardous if
improperly used or handled, for example, bat-
tery acid.
Your vehicle should only be serviced by per-
sons fully competent to do so. Serious person-
al injury may result to persons not experienced
in servicing vehicles. Always use the proper tools and make certain
that they are well maintained. Never get under the vehicle supported only
by a jack. Always use a safety stands to sup-
port the vehicle. Never keep the engine running in a poorly
ventilated area, such as a garage or other
closed areas. Do not smoke or allow open flames around
the fuel or battery. This will cause a fire. Because the fuel system is under pressure,
replacement of the fuel filter should be per-
formed only by your SUBARU dealer. Wear adequate eye protection to guard
against getting oil or fluids in your eyes. If
something does get in your eyes, thoroughly
wash them out with clean water. Do not tamper with the wiring of the SRS air-
bag system or seatbelt pretensioner system, or
attempt to take its connectors apart, as that may activate the system or it can render it inop-
erative. The wiring and connectors of these
systems are yellow for easy identification. NEV-
ER use a circuit tester for these wiring.
If your SRS airbag or seatbelt pretensioner
needs service, consult your nearest SUBARU
dealer.
Before checking or servicing in the en-
gine compartment
Always stop the engine and set the parking
brake firmly to prevent the vehicle from mov-
ing. Always let the engine cool down. Engine
parts become very hot when the engine is run-
ning and remain hot for some time after the en-
gine is stopped. Do not spill engine oil, engine coolant, brake
fluid or any other fluid on hot engine compo-
nents. This may cause a fire. Always remove the key from the ignition
switch. When the ignition switch is in the “ON”
position, the cooling fan may operate suddenly

Automatic transmission fluid
Checking the fluid level
The automatic transmission fluid expands largely as
its temperature rises; the fluid level differs according to
fluid temperature. Therefore, there are two different
scales for checking the level of hot fluid and cold fluid
on the dipstick.
Though the fluid level can be checked without warm-
ing up the fluid on the “COLD” range, we recommend
checking the fluid level when the fluid is at operating temperature. Checking the fluid level when the fluid is hot
Check the fluid level monthly.
1. Drive the vehicle several miles to raise the temper-
ature of the transmission fluid up to normal operating
temperature; 154 to 176 °F (70 to 80 °C) is normal.
2. Park the vehicle on a level surface and set the park-
ing brake.
3. First shift the selector lever in each position. Then
shift it in the “P” position, and run the engine at idling
speed. 1) Yellow handle
