Cargo area cover (if equipped)
The cargo area cover is provided for covering the car-
go area and to protect its contents from direct sunlight.
This cover is detachable to make room for additional
cargo. !Using the cover
To extend the cover, pull the end of the cover out of
the housing, then insert its hooks into the catches as
shown. To rewind it, unhook it from the catches and it
will rewind automatically. You should hold on to the
cover and guide it back into the cover housing while it is rewinding.
Do not place anything on the extended cover.
Putting excessive weight on the extended cov-
er can break it and an object on the cover could
tumble forward in the event of a sudden stop or
collision. This could cause serious injury.
Be careful not to scratch the rear gate stays
while extending and rewinding the cover.
Scratches on the stays could cause leakage of
gas from the stays, which may result in their in-
ability to hold the rear gate open.

Use of a fuel which is low in quality or use of an
inappropriate fuel additive may cause engine
damage.
! Fuel requirements
! 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. ! 2.0 Liter (turbo) models
The 2.0 Liter turbo engine is designed to operate using
premium unleaded gasoline with an octane rating of
91 AKI or higher. If premium unleaded gasoline is not
available, regular unleaded gasoline with an octane
rating of 87 AKI or higher may be temporarily used.
For optimum engine performance and driveability, it is
recommended that you use premium grade unleaded
gasoline. !
2.5 Liter (turbo) model
The 2.5 Liter turbo engine is designed to operate using
super-premium unleaded gasoline with an octane rat-
ing of 93 AKI or higher. If super-premium unleaded
gasoline with an octane rating of 93 AKI or higher is
not available, premium unleaded gasoline with an oc-
tane rating of 91 AKI or higher can be used. For opti-
mum engine performance and driveability, it is recom-
mended that you use super-premium grade unleaded
gasoline with an octane rating of 93 AKI or higher. ! 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. ! 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

3. Stop filling the tank after the fuel filler pump auto-
matically stops. Do not add any more fuel.
4. Put the cap back on, turn it clockwise until you hear
a clicking noise. Be certain not to catch the tether un-
der the cap while tightening.
5. Close the fuel filler lid completely.
If you spill any fuel on the painted surface, rinse it off
immediately. Otherwise, the painted surface could be
damaged.
NOTE
If the fuel filler cap is not tightened until it clicks or
if the tether is caught under the cap, the CHECK
ENGINE warning light may come on. Refer to the
“Warning and indicator lights” section located in
chapter 3.
" 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 tank and emis-
sion control system might be damaged.

inspection program or its contractors or licens-ees.
The EPA has issued regulations for inspecting the On-
Board Diagnostic (OBD) system as part of the state
emissions inspection. The OBD system is designed to
detect engine and transmission problems that might
cause vehicle emissions to exceed allowable limits.
These inspections apply to all 1996 model year and
newer passenger cars and light trucks. Several states
plus the District of Columbia have opted to start the
OBD system inspection prior to the required EPA reg-
ulation effective date of January 1, 2002. Other states
will add OBD system inspection in 2002. " The inspection of the OBD system consists of a vi-
sual operational check of the “ CHECK ENGINE” warn-
ing light/malfunction indicator lamp (MIL) and an ex-
amination 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 illumi-
nation is observed, there is no stored diagnostic trou-
ble 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 readinessmonitors “ 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.
