Towing with a sling-type truck
WARNING
■
Installing towing eyelets to the vehicle
Make sure that towing eyelet is installed securely.
If not securely installed, towing eyelets may come loose during towing. This
may lead to accidents that cause serious injury or even death.
■ After towing
● Always remove the towing eyelet. Failure to do so can cause the SRS air-
bags to not operate correctly in the event of a frontal collision.
● Always remove the towing eyelets. Failure to do so may prevent the fuel
pump shut off system from operating properly if the vehicle receives an
impact from the rear.

Fuel information
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your SUBARU has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ If your engine knocks
● Consult your SUBARU dealer.
● You may occasionally notice light knocking for a short time while acceler-
ating or driving uphill. This is normal and there is no need for concern.
■ Gasoline quality
In very few cases, driveability problems may be caused by the brand of gas-
oline you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your SUBARU dealer.
■ Fuel octane rating
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 vehi-
cle sometimes knocks lightly when you drive up a hill or when you acceler-
ate. Contact your SUBARU dealer if you use a fuel with the specified octane
rating and your vehicle knocks heavily or persistently.
RON
This octane rating is the Research Octane Number.
AKI
This octane rating is the average of the Research Octane and Motor Octane
numbers and is commonly referred to as the Anti Knock Index (AKI). The engine is designed to operate at maximum performance using
unleaded gasoline with an octane rating of 93 AKI (98 RON) or
higher. If 93 AKI (98 RON) fuel is not readily available in your area,
unleaded gasoline with an octane rating of 91 AKI (95 RON) may be
used with no detriment to engine durability or driveability. However,
you may notice a slight decrease in maximum engine performance
and you may hear some knocking (pinging) from the engine while
using 91 AKI (95 RON) fuel. Use of 91 AKI (95 RON) fuel will not affect
your warranty coverage.

■
SUBARU does not recommend blended gasoline
● If you use gasohol in your SUBARU, be sure that it has an octane rating
no lower than 93 AKI (98 RON).
● SUBARU DOES NOT recommend the use of gasoline containing metha-
nol.
■ SUBARU does not recommend gasoline containing MMT
Some gasoline contains octane enhancing additive called MMT (Methylcy-
clopentadienyl Manganese Tricarbonyl).
SUBARU DOES NOT recommend the use of gasoline that contains MMT. If
fuel containing MMT is used, your emission control system may be
adversely affected.
The malfunction indicator lamp on the instrument cluster may come on. If
this happens, contact your SUBARU dealer for service. ●
Use only gasoline containing a maxi-
mum of 10% ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 10% etha-
nol, including from any pump labeled
E15, E30, E50, E85 (which are only
some examples of fuel containing more
than 10% ethanol).
DO NOT use gasoline
containing more than 10%
ethanol.

(50% ethanol)
(85% ethanol)
