Consumer information and Reporting safety defects
& Tire care –maintenance and
safety practices.
Check on a daily basis that the
tires are free from serious damage,
nails, and stones. At the same time,
check the tires for abnormal wear.
.
Inspect the tire tread regularly
and replace the tires before their
tread wear indicators become visi-
ble. When a tire ’streadwear
indicator becomes visible, the tire
is worn beyond the acceptable limit
and must be replaced immediately.
With a tire in this condition, driving
at even low speeds in wet weather
can cause the vehicle to hydro-
plane. Possible resulting loss of
vehiclecontrolcanleadtoan
accident.
.
To maximize the life of each tire
and ensure that the tires wear
uniformly, it is best to rotate the
tires every 7,500 miles (12,000 km).
For information about the tire rota-
tion order, refer to “Tire rotation ”
F 11-36
.Replace any damaged or
unevenly worn tires at the time of rotation. After tire rotation, adjust
the tire pressures and make sure
the wheel nuts are correctly tigh-
tened. For information about the
tightening torque and tightening
sequence for the wheel nuts, refer
to
“Flat tires” F9-6
.
& Vehicle load limit –how to
determineThe load capacity of your vehicle is
determined by weight, not by avail-
able cargo space. The load limit of
your vehicle is shown on the
vehicle placard attached to the
driver ’s side B-pillar. Locate the
statement “The combined weight
of occupants and cargo should
never exceed XXX kg or XXX lbs ”
on your vehicle ’s placard.
Thevehicleplacardalsoshows
seating capacity of your vehicle.
The total load capacity includes the
total weight of driver and all pas-
sengers and their belongings, any
cargo, any optional equipment such
as a trailer hitch, roof rack or bike carrier, etc., and the tongue load of
a trailer. Therefore cargo capacity
can be calculated by the following
method.
Cargo capacity = Load limit
(total
weight of occupants + total weight
of optional equipment + tongue
load of a trailer (if applicable))
For information about vehicle load-
ing, refer to “Loading your vehicle ”
F 8-12
.
NOTEYour vehicle is neither designed
nor intended to be used for
trailer towing. Therefore, never
tow a trailer with your vehicle.

GAS STATION REFERENCE
&
Fuel:
! Non-turbo models
Use only unleaded gasoline with an octane rating of 87 AKI
(90 RON) or higher .
! Turbo models except STI
Use premium unleaded gasoline with an octane rating of 91
AKI (95 RON) or higher . If premium unleaded gasoline with an
octane rating of 91 AKI (95 RON) is not available, regular
unleaded gasoline with octane rating of 87 AKI (90 RON) or
higher may be temporarily used. For optimum engine perfor-
mance and driveability, it is required that you use premium
grade unleaded gasoline with an octane rating of 91 AKI (95
RON) or higher.
! STI
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 while using 91 AKI (95 RON)
fuel. Use of 91 AKI (95 RON) fuel will not affect your warranty
coverage.
&
Fuel octane rating:
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). Refer to “Fuel octane rating”F7-3.&
Fuel capacity:
16.9 US gal (64 liters, 14.1 Imp gal)&
Engine oil:
Use SUBARU approved motor oil or equivalent.
For the details, refer to “Engine oil”F 12-5.&
Engine oil capacity:
4.4 US qt (4.2 liters, 3.7 Imp qt)&
