„ Fuel requirements
T 2.5 Liter models
The 2.5 Liter engine is designed to operate using un-
leaded gasoline with an octane rating of 87 AKI or
higher. T 3.0 Liter models
The 3.0 Liter engine is designed to operate using pre-
mium unleaded gasoline with an octane rating of 91
AKI or higher. Regular unleaded gasoline with an oc-
tane rating of 87 AKI may be used if necessary. For
optimum engine performance and driveability, it is rec-
ommended that you use premium grade unleaded
gasoline. T Fuel octane rating
This octane rating is the average of the Research Oc- tane and Motor Octane numbers and is commonly re-
ferred to as the Anti Knock Index (AKI).
Using a gasoline with a lower octane rating can cause
persistent and heavy knocking, which can damage the
engine. Do not be concerned if your vehicle some-
times knocks lightly when you drive up a hill or when
you accelerate. See your dealer or a qualified service
technician if you use a fuel with the specified octane
rating and your vehicle knocks heavily or persistently. T
Unleaded gasoline
The neck of the fuel filler pipe is designed to accept
only an unleaded gasoline filler nozzle. Under no cir-
cumstances should leaded gasoline be used because
it will damage the emission control system and may
impair driveability and fuel economy. T California fuel
If your vehicle was certified to California Emission
Standards as indicated on the underhood tune-up la-
bel. It is designed to optimize engine and emission
control system performance with gasoline that meets
the clean burning low-sulfur California gasoline speci-
fications. If you live in any other state than California,
your vehicle will operate on gasoline meeting Federal
specifications. Gasoline sold outside California is per-
mitted to have higher sulfur levels, which may affect
the performance of your vehicle’s catalytic converter

cal system and cause a malfunction of your ve-
hicle’s lighting system.
Connection of trailer lights to your vehicle’s electrical
system requires modifications to the vehicle’s lighting
circuit to increase its capacity and accommodate wir-
ing changes. To ensure the trailer lights are connected
properly, please consult your SUBARU dealer. Check
for proper operation of the turn signals, the brake
lights and parking lights each time you hitch up. T Tires
Never tow a trailer when the temporary spare
tire is used. The temporary spare tire is not de-
signed to sustain the towing load. Use of the
temporary spare tire when towing can result in
failure of 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 tow-
ing conditions is shown in chapter 12, “Specifications” and in “GAS STATION REFERENCE” at the end of
this manual. Adjust the rear tire pressure to the recom-
mended pressure when the tires are cold. Normal
pressure should be maintained in the front tires.
Trailer tire condition, size, load rating and proper infla-
tion 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 precaution against getting a flat tire, be
sure that the spare tire is firmly secured. „
Trailer towing tipsyNever exceed 45 mph (72 km/h) when towing
a trailer in hilly country on hot days. y 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

al times, applying the same pedal force each time. The
distance the pedal travels should not vary.
2. With the brake pedal depressed, start the engine.
The pedal should move slightly down to the floor.
3. With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds. The
pedal height should not change.
4. Start the engine again and run for about one minute
then turn it off. Depress the brake pedal several times
to check the brake booster. Brake booster operates
properly if the pedal stroke decreases with each de-pression.Brake pedal
Check the brake pedal free play and reserve distance
according to the maintenance schedule in the “War-
ranty and Maintenance Booklet”. „Checking the brake pedal free play

tor, it will result in the need for costly brake ro-
tor repair or replacement.

the brake pads wear close to their service limit, the
wear indicator makes a very audible scraping noise
