BRZ_U
CAUTION
■When replacing the tires (vehicles with a tire pressure monitoring
system)
When removing or fitting the wheels, tires or the tire pressure warning
valve and transmitter, contact your SUBARU dealer as the tire pressure
warning valve and transmitter may be damaged if not handled correctly.
■To avoid damage to the tire pressure warning valves and transmit-
ters (vehicles with a tire pressure monitoring system)
When a tire is repaired with liquid sealants, the tire pressure warning
valve and transmitter may not operate properly. If a liquid sealant is
used, contact your SUBARU dealer or other qualified service shop as
soon as possible. Make sure to replace the tire pressure warning valve
and transmitter when replacing the tire. (→P. 371)
■Replacing a flat tire
Do not hit and bend the disc rotor backing plate when removing and
installing the tire. A bent backing plate may scrape against the disc rotor
and cause noise while the vehicle is in motion.
■Stowing the jack
When stowing the jack in the jack holder, make sure that the part that the
jack handle attaches to is pointing towards the inside of the trunk. Failure
to do so may damage the vehicle body.

Oil viscosity (0W-20 is explained here as an example):
• The 0W in 0W-20 indicates the characteristic of the oil which allows
cold startability. Oils with a lower value before the W allow for easier
starting of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated at high
speeds, or under extreme load conditions.
How to read oil container labels:
Either or both API registered marks are added to some oil containers
to help you select the oil you should use.
API Service Symbol
Top portion: The oil quality desig-
nation by API (American Petro-
leum Institute) (SN or SN PLUS)
Center portion: The SAE viscosity
grade (SAE 0W-20)
Lower portion: “RESOURCE
CONSERVING” means that the
oil has fuel saving and environ-
mental protection capabilities.
ILSAC Certification Mark
The ILSAC (International Lubri-
cant Specification Advisory Com-
mittee) Certification Mark is
displayed on the front of the con-
tainer.

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.
(15% ethanol)
(50% ethanol)
(85% ethanol)

Tre ad w ea r
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use. Performance may differ significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
■Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ability to stop on wet pavement as
measured under controlled conditions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci-
fied indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
Grade C corresponds to a level of performance which all passenger
car tires must meet under the Federal Motor Vehicle Safety Standard
No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
