reduce HC, CO and NOx in exhaust gas-
es, thus providing cleaner exhaust.
To avoid damage to the catalytic convert- er: yUse only unleaded gasoline. Even a
small amount of leaded gasoline will dam-
age the catalytic converter. y Never start the engine by pushing or
pulling the vehicle. y Avoid racing the engine.
y Never turn off the ignition switch while
the vehicle is moving.y Keep your engine tuned-up. If you feel
the engine running rough (misfiring, back-
firing or incomplete combustion), have
your vehicle checked and repaired by an
authorized SUBARU dealer. y Do not apply undercoating or rust pre-
vention treatment to the heat shield of cat-
alytic converter and the exhaust system.Periodic inspections
To keep your vehicle in the best condition
at all times, always have the recommend-
ed maintenance services listed in the
maintenance schedule in the “Warranty
and Maintenance Booklet” performed at
the specified time or mileage intervals.Driving in fo reign countries
When planning to use your vehicle in an- other country: y Confirm the availability of the correct fu-
el. (Refer to the “Fuel requirements” sec-
tion in chapter 7.) y Comply with all regulations and require-
ments of each country.

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.
Keep the door locks from freezing by

required due to the additional load. (Refer
to “Maintenance schedule under severe
driving conditions” in the “Warranty and
Maintenance Booklet”.)
Under no circumstances should a trailer
be towed with a new vehicle or a vehicle
with any new powertrain component (en-
gine, transmission, differential, wheel
bearings, etc.) for the first 1,000 miles
(1,600 km) of driving. „
Maximum load limits
TTotal trailer weight
Total trailer weight
The total trailer weight (trailer weight plus
its cargo load) must never exceed the
maximum weight indicated in the following table.
Never exceed the maximum load
limits explained in the following. Ex-
ceeding the maximum load limits
could cause personal injury and/or
vehicle damage. y Adequate size trailer brakes are
required when the trailer and its
cargo exceed 1,000 lbs (453 kg)
total weight.
yBefore towing a trailer, check the
trailer total weight, GVW, GAWs
and tongue load. Make sure the
load and its distribution in your
vehicle and trailer are acceptable.

Maintenance and serviceMaintenance schedule
The scheduled maintenance items re-
quired to be serviced at regular intervals
are shown in the “Warranty and Mainte-
nance Booklet”.
For details of your maintenance schedule,
read the separate “Warranty and Mainte-
nance Booklet”.Maintenance precautions
When maintenance and service are re-
quired, it is recommended that all work be
done by an authorized SUBARU dealer.
If you perform maintenance and service
by yourself, you should familiarize your-
self with the information provided in this
section on general maintenance and ser-
vice for your SUBARU.
Incorrect or incomplete service could
cause improper or unsafe vehicle opera-
tion. Any problems caused by improper
maintenance and service performed by
you are not eligible for warranty coverage.
yTesting of an All-Wheel Drive ve-
hicle must NEVER be performed
on a single two-wheel dynamome-ter or similar apparatus. Attempt-
ing to do so will result in transmis-
sion damage and in uncontrolled
vehicle movement and may cause
an accident or injuries to persons
nearby.
y Always select a safe area when
performing maintenance on yourvehicle.
yAlways be very careful to avoid in-
jury when working on the vehicle.
Remember that some of the mate-
rials in the vehicle may be hazard-
ous if improperly used or handled,
for example, battery acid.
yYour vehicle should only be ser-
viced by persons fully competent
to do so. Serious personal injury
may result to persons not experi-
enced in servicing vehicles.
yAlways use the proper tools and
make certain that they are well
maintained.
yNever get under the vehicle sup-
ported only by a jack. Always use
a safety stands to support the ve- hicle.
yNever keep the engine running in
a poorly ventilated area, such as a
garage or other closed areas.
yDo not smoke or allow open
flames around the fuel or battery.
This will cause a fire.
yBecause the fuel system is under
pressure, replacement of the fuel
filter should be performed only by
your SUBARU dealer.

11 - 1 0 Maintenance and service
If you check the oil level just after stopping
the engine, wait a few minutes for the oil to
drain back into the oil pan before checking
the level.
To prevent overfilling the engine oil, do not
add any additional oil above the upper lev-
el when the engine is cold.
In 2.5-liter-engine models, the dipstick has
a notch above the upper level.
Just after driving or while the engine is
warm, the engine oil level reading may be
in a range between the upper level and
the notch mark. This is caused by thermal
expansion of the engine oil. „Changing the oil and oil filter
Change the oil and oil filter according to
the maintenance schedule in the “Warran-
ty and Maintenance Booklet”.
The engine oil and oil filter must be
changed more frequently than listed in the
maintenance schedule when driving on
dusty roads, when short trips are frequent-
ly made, or when driving in extremely cold
whether.
1. Warm up the engine by letting the en-
gine idle for approximately 10 minutes to
ease draining the engine oil.
2. Park the vehicle on a level surface and
stop the engine. 3. Remove the oil filler cap.
2.5-liter models
3.0-liter models
4. Drain out the engine oil by removing the drain plug while the engine is still
warm. The used oil should be drained into
an appropriate container and disposed of
properly.
5. Wipe the seating surface of the drain
plug with a clean cloth and tighten it se-
curely with a new sealing washer after the
oil has completely drained out.

Never attempt to remove the radia-
tor cap until the engine has been
shut off and has cooled down com-
pletely. Since the coolant is under
pressure, you may suffer serious
burns from a spray of boiling hot
coolant when the cap is removed.
