After driving through tall grass, mud, rock, 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 under-
body. If the vehicle is used with these materials trapped or adhering to
the underbody, a mechanical breakdown or fire could occur. Secure all cargo carried inside the vehicle and make certain that it is
not piled higher than the seatbacks. During sudden stops or jolts, unse-
cured cargo could be thrown around in the vehicle and cause injury. 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. Cargo should be evenly distributed over the cargo bed. Keep heavier
items as low and far forward as possible. Loading the vehicle improperly
can deteriorate handling capability and contribute to loss of vehicle con-
trol. Be sure the cargo is secured properly. Unsecured cargo in the cargo
bed can be thrown around when driving on off-road. To prevent loose
cargo from entering the passenger compartment, always close the
switchback door while driving off-road. Always close the tailgate while driving off-road. Also remove the bed
extender (if so equipped) to avoid damage. If you must rock the vehicle to free it from sand or mud, depress the
accelerator pedal slightly and move the selector lever back and forth be-tween “D” and “R” repeatedly. Do not race the engine. For the best pos-
sible traction, avoid spinning the wheels when trying to free the vehicle. 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). Never equip your vehicle with tires larger than those specified in this
manual. Frequent driving of an AWD vehicle under 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 specified in the main-
tenance 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 precautions such as those listed above is

Trailer towing
Your vehicle is designed and intended to be used primarily to carry pas-
sengers and cargo. Towing a trailer puts additional loads on your
vehicle’s engine, drivetrain, brakes, tires and suspension and has an ad-
verse effect on fuel economy.
If you do decide to tow a trailer, your safety and satisfaction depend
upon proper use of correct equipment and cautious operation of your ve-
hicle. Seek the advice of your SUBARU dealer to assist you in purchas-
ing a hitch and other necessary towing equipment appropriate for your
vehicle. In addition, be sure to follow the instructions on correct installa-
tion and use provided by the trailer and other towing equipment
manufacturers.
SUBARU assumes no responsibility for injuries or vehicle damage that
result from trailer towing equipment, or from any errors or omissions in
the instructions accompanying such equipment or for your failure to fol-
low the proper instructions.
Warranties and maintenance
SUBARU warranties do not apply to vehicle damage or malfunction
caused by trailer towing. If you use your vehicle to tow a trailer, more
frequent maintenance will be 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 (engine, transmis-
sion, differential, wheel bearings, etc.) for the first 1,000 miles (1,600km) of driving. Maximum load limits
WARNING
Never exceed the maximum load limits explained below. Exceed- ing the maximum load limits could cause personal injury and/or
vehicle damage.

10-6
Before the beginning of winter, check the condition of underbody
components, such as the exhaust system, fuel and brake lines, brake
cables, suspension, steering system, floor pan, and fenders. If any of
them are found to be rusted, they should be given an appropriate rust
prevention treatment or should be replaced. Contact your SUBARU
dealer to perform this kind of maintenance and treatment if you needassistance. Repair chips and scratches in the paint as soon as you find them.
Check the interior of the vehicle for water and dirt accumulation under
the floor mats because that could cause corrosion. Occasionally
check under the mats to make sure the area is dry.
Keep your garage dry. Do not park your vehicle in a damp, poorly
ventilated garage. In such a garage, corrosion can be caused by
dampness. If you wash the vehicle in the garage or put the vehicle
into the garage when wet or covered with snow, that can causedampness.
If your vehicle is operated in cold weather and/or in areas where road
salts and other corrosive materials are used, the door hinges and
locks, trunk lid lock, and hood latch should be inspected and lubri-
cated periodically.
Cleaning the interior
Use a vacuum cleaner to get rid of the dust and dirt. Wipe the vinyl areas with a clean, damp cloth. Seat fabric
Remove loose dirt, dust or debris with a vacuum cleaner. If the dirt is
caked on the fabric or hard to remove with a vacuum cleaner, use asoft blush then vacuum it.
Wipe the fabric surface with a tightly wrung cloth and dry the seat
fabric thoroughly. If the fabric is still dirty, wipe using a solution of mild
soap and lukewarm water then dry thoroughly.
If the stain does not come out, try a commercially-available fabric

The scheduled maintenance items required to be serviced at regular in-
tervals are shown in the “Warranty and Maintenance Booklet ”.
For details of your maintenance schedule, read the separate “Warranty
and Maintenance Booklet ”.
Maintenance precautions
When maintenance and service are required, it is recommended that all
work be done by an authorized SUBARU dealer.
If you perform maintenance and service by yourself, you should familiar-
ize yourself with the information provided in this section on general main-
tenance and service for your SUBARU.
Incorrect or incomplete service could cause improper or unsafe vehicle
operation. Any problems caused by improper maintenance and service
performed by you are not eligible for warranty coverage. WARNING
Testing of an All-Wheel Drive vehicle must NEVER be per-
formed on a single two-wheel dynamometer or similar apparatus.Attempting to do so will result in transmission damage and inuncontrolled vehicle movement and may cause an accident or
injuries to persons nearby. Always select a safe area when performing maintenance on
your vehicle. Always be very careful to avoid injury when working on the ve-
hicle. Remember that some of the materials in the vehicle may behazardous if improperly used or handled, for example, batteryacid. Your vehicle should only be serviced by persons fully compe-
tent to do so. Serious personal injury may result to persons not
experienced in servicing vehicles.

Changing the oil and oil filter
Change the oil and oil filter according to the maintenance schedule in the “Warranty 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 frequently made, or when driving in extremely
cold whether.
1. Warm up the engine by letting the engine idle for about 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.
HBB005BB
4. Drain out the engine oil by removing the drain plug while the en-
gine is still warm. The used oil should be drained into an appropriate
container and disposed of properly.
WARNING
Be careful not to burn yourself with hot engine oil.
5. Wipe the seating surface of the drain plug with a clean cloth and
tighten it securely with a new sealing washer after the oil has com-pletely drained out.

12. Reinstall the cover under the oil filter.
13. Pour engine oil through the filler neck.
Oil capacity (Guideline): 4.2 US qt (4.0 liters, 3.5 Imp qt)
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 refilling the
engine with oil, therefore, you must use the dipstick to confirm that the
level is correct.
14. Start the engine and make sure that no oil leaks appear aroundthe filter ’s rubber seal and drain plug.
15. Run the engine until it reaches the normal 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 CAUTION
Use only engine oil with the recommended grade and viscosity.
Oil grade: ILSAC GF-3, which can be identified with the new API certification mark (Starburst mark)
or API classification SL with the words “ENERGY CON-
SERVING” (if you cannot obtain the oil with SL grade,
you may use SJ grade “ENERGY CONSERVING ” oil).
These recommended oil grades can be identified by looking for either
or both of the following marks displayed on the oil container.

Recommended grade and viscosity under severe driving conditions
If the vehicle is used in desert areas, in areas with very high tempera-
tures, or used for heavy-duty applications such as towing a trailer, use
of oil with the following grade and viscosities is recommended.
API classification SL (or SJ): SAE viscosity No.: 30, 40, 10W-50,
20W-40, 20W-50
Cooling system
WARNING
Never attempt to remove the radiator cap until the engine has
been shut off and has cooled down completely. Since the coolantis under pressure, you may suffer serious burns from a spray ofboiling hot coolant when the cap is removed.
CAUTION
The cooling system has been filled at the factory with a high
quality, corrosion-inhibiting, year-around coolant which providesprotection against freezing down to –33°F ( –36 °C). For adding,
use genuine SUBARU coolant or an equivalent: a mixture of 50%
soft water and 50% ethylene-glycol basis coolant. Use of improp-er coolants may result in corrosion in the cooling system. It is im-portant to maintain protection against freezing and corrosion,even if freezing temperatures are not expected. Never mix differ-ent kinds of coolant. Do not splash the engine coolant over painted parts. The alco-
hol contained in the engine coolant may damage the paint sur-face.
Hose and connections
Your vehicle employs an electric cooling fan which is thermostatically
