and may produce a sulfur exhaust odor or smell. SUBARU recom-
mends that you try a different brand of unleaded gasoline having low-
er sulfur to determine if the problem is fuel related before returningyour vehicle to an authorized dealer for service. Gasoline for cleaner air
Your use of gasoline with detergent additives will help prevent depos-
its from forming in your engine and fuel system. This helps keep your
engine in tune and your emission control system working properly,
and is a way of doing your part for cleaner air. If you continuously use
a high quality fuel with the proper detergent and other additives, youshould never need to add any fuel system cleaning agents to your
fuel tank.
Many gasolines are now blended with materials called oxygenates.
Use of these fuels can also help keep the air cleaner. Oxygenated
blend fuels, such as MTBE (Methyl Tertiary Butyl ether) or ethanol(ethyl or grain alcohol) may be used in your vehicle, but should con-
tain no more than 15% MTBE or 10% ethanol for the proper operationof your SUBARU.
In addition, some gasoline suppliers are now producing reformulated
gasoline, which is designed to reduce vehicle emissions. SUBARU
approves the use of reformulated gasoline.
If you are not sure what the fuel contains, you should ask your service station operators if their gasoline contains detergents and oxygenates
and if they have been reformulated to reduce vehicle emissions. As additional guidance, only use fuels suited for your vehicle as ex-
plained below. Fuel should be unleaded and have an octane rating no lower than
that specified in this manual. Methanol (methyl or wood alcohol) is sometimes mixed with un-
leaded gasoline. Methanol can be used in your vehicle ONLY if it
does not exceed 5% of the fuel mixture AND if it is accompanied by
sufficient quantities of the proper cosolvent and corrosion inhibitors
required to prevent damage to the fuel system. Do not use fuel con-

7-4
taining methanol EXCEPT under these conditions.
If undesirable drivability problems are experienced and you sus-
pect they may be fuel related, try a different brand of gasoline before
seeking service at your SUBARU dealer. Fuel system damage or drivability problems which result from the
use of improper fuel are not covered under the SUBARU Limited War-
ranty.
Fuel filler door and cap Refueling
WARNING
Gasoline vapor is highly flammable. Before refueling, always
first stop the engine and make sure that there are no lighted ciga- rettes, open flames or electrical sparks in the adjacent area. When opening the cap, do not remove the cap quickly. Fuel
may be under pressure and spray out of the fuel filler neck espe-
cially in hot weather, which may cause injury. Never fill gasoline containers on the cargo bed. Static electric-
ity may ignite gasoline vapor when filling portable containers.
Approved containers must be removed from the vehicle and
placed on the ground when filling.Do not fill any portable container on a vehicle.
CAUTION
Never add any cleaning agents to the fuel tank. The addition of
a cleaning agent may cause damage to the fuel system. Make sure that the cap is tightened until it clicks to prevent
fuel spillage in the event of an accident. Do not let fuel spill on the exterior surfaces of the vehicle.
Fuels may cause paint damage, which is not covered under the
SUBARU Limited Warranty. Always use a genuine SUBARU fuel filler cap. If you use the
wrong cap, it may not fit or have proper venting, and your fuel

At state inspection time, remember to tell your inspection or service
station in advance not to place your Subaru AWD vehicle on a two-
wheel dynamometer. Otherwise, serious transmission damage willresult.
Some states have started using dynamometers in their state inspection
programs in order to meet their obligation under federal law to implement
stricter vehicle emission standards to reduce air pollution from cars. A
dynamometer is a treadmill or roller-like testing device that allows your
car’s wheels to turn while the car remains in one place. Depending on
the severity of a state ’s air pollution problems, the states must adopt
either a “basic” or “enhanced” vehicle emission inspection test. Nor-
mally, a portion of the basic emission test consists of an emission
inspector inserting an analyzer probe into the exhaust pipe of an idling
vehicle for a short period of time. States with more severe air pollution
problems are required to adopt an enhanced vehicle emission test. This
test simulates actual driving conditions on a dynamometer and permits
more accurate measurement of tailpipe emitted pollution than the basic emission test.
The U.S. Environmental Protection Agency (EPA) and states using two-
wheel dynamometers in their emission testing programs haveEXEMPTED Subaru AWD vehicles from the portion of the testing pro-
gram that involves a two-wheel dynamometer.
There are some states that use four-wheel dynamometers in their testing
programs. When properly used, that equipment will not damage an AWD Subaru vehicle.
Under no circumstances should the rear wheels be jacked off the
ground, nor should the drive shaft be disconnected for state emission testing.
The EPA has issued regulations for inspecting the On-Board Diagnostic
(OBD) system as part of the state emissions inspection. The OBD sys-
tem is designed to detect engine and transmission problems that mightcause vehicle emissions to exceed allowable limits. These inspectionsapply to all 1996 model year and newer passenger cars and light trucks. The inspection of the OBD system consists of a visual operational

7-8
check of the “CHECK ENGINE ” warning light/malfunction indicator lamp
(MIL) and an examination of the OBD system with an electronic scan tool while the engine is running. A vehicle passes
the OBD system inspection 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. 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 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 three. 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 be-
fore you start driving.
1. Check that all windows, mirrors, and lights are clean and unob- structed.
2. Check the appearance and condition of the tires. Also check tires for
proper inflation.
3. Look under the vehicle for any sign of leaks.
4. Check that the hood is 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 theirseatbelts.
8. Check the operation of the warning and indicator lights when the igni-
tion switch is turned to the “ON” position.

nTires
WARNING
Never tow a trailer when the temporary spare tire is used. The temporary spare tire is not designed to sustain the towing load.
Use of the temporary spare tire when towing can result in failureof the spare tire and/or less stability of the vehicle.
Make sure that all the tires on your vehicle are properly inflated.
The recommended cold tire pressure under trailer towing conditions
is indicated on the tire placard located under the door striker on the
driver’ s side. Adjust the rear tire pressure to the recommended pres-
sure shown on the tire placard when the tires are cold. Normal pres-
sure should be maintained in the front tires.
Trailer tire condition, size, load rating and proper inflation pressure
should be in accordance with the trailer manufacturer ’s specifications.
In the event your vehicle gets a flat tire when towing a trailer, ask a
commercial road service to repair the flat tire.
If you carry a regular size spare tire in your vehicle or trailer as a pre-
caution against getting a flat tire, be sure that the spare tire is firmly
secured. Trailer towing tips CAUTION
Never exceed 45 mph (72 km/h) when towing a trailer in hilly
country on hot days. When towing a trailer, steering, stability, stopping distance and
braking performance will be different from normal operation. For
safety’ s sake, you should employ extra caution when towing a
trailer and you should never speed. You should also keep the fol-lowing tips in mind:

9. Use the wheel nut wrench to securely tighten the wheel nuts to the
specified torque, following the tightening order in the illustration.
The torque for tightening the nuts is 66 to 81 ft-lb (90 to 110 N-m, 9 to
11 kg-m). This torque is equivalent to applying about 88 to 110 lbs
(40 to 50 kg) at the top of the wheel nut wrench provided to your ve-
hicle. Never use your foot on the wheel nut wrench or a pipe exten-
sion on the wrench because you may exceed the specified torque.
Have the wheel nut torque checked at the nearest automotive service
facility. Storage of the flat tire CAUTION
Secure the flat tire in the cargo bed (with the outer side of the
wheel facing up) by using the designated tire holding rod and
retainer. If the flat tire is not properly secured, it may fall out andcreate a dangerous road hazard that could lead to a serious acci-dent. Do not store the flat tire under the floor. Doing so could dam-
age the underside of the vehicle.
1. Take the tire holding rod and retainer out of the tool bag.

the radiator. After the pressure has been fully released, remove the
cap by pressing down and turning it.
Towing
WARNING
Never tow AWD vehicles (both AT and MT) with the front wheelsraised off the ground while the rear wheels are on the ground, orwith the rear wheels raised off the ground while the front wheelsare on the ground. This will cause the vehicle to spin away due tothe operation or deterioration of the center differential.
HB9064BA
If towing is necessary, it is best done by your SUBARU dealer or a com-
mercial towing service. Observe the following procedures for safety.
Towing and tie-down hooks
CAUTION
Use only specified towing hooks and tie-down hooks. Never
use suspension parts or other body parts for towing or tie-downpurposes. Never use the tie-down hook closest to the muffler under the
vehicle for towing purposes. Do not apply excessive lateral load to the towing hooks.

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.
