WARNING
■
TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ When the Vehicle stability control (VSC) and/or brake LSD function is
activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/Vehicle stability co ntrol (VSC) systems are turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/Vehicle stability control (VSC) systems off
unless necessary.
■ Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and Vehicle stability cont rol (VSC) systems will not function
correctly if different tires are installed on the vehicle.
Contact your SUBARU dealer for further information when replacing tires or
wheels.
■ Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.

Vehicle exterior
ItemsCheck points
Door/trunk lid • Operate smoothly?
Engine hood • The lock system works properly?
Fluid leaks • Is there any leakage after park-
ing?
Ti re • Inflation pressure is correct?
• Tire surfaces not worn or dam-
aged?
• Tires rotated according to the maintenance schedule?
• Wheel nuts are not loose?
Windshield wipers
•The wiper blades should not show
any signs of cracking, splitting,
wear, contamination or deforma-
tion.
•The wiper blades should clear the
windshield without streaking or
skipping.
WARNING
■ If the engine is running
Turn the engine off and ensure that there is adequate ventilation before per-
forming maintenance checks.

Maintenance and care
BRZ_U
Installing tire pressure warning valves and transmitters (vehicles
with a tire pressure monitoring system)
When replacing tires or wheels, tire pressure warning valves and
transmitters must also be installed.
When new tire pressure warning valves and transmitters are
installed, new tire pressure warning valve and transmitter ID codes
must be registered in the tire pressure warning computer and tire
pressure monitoring system must be initialized. Have tire pressure
warning valve and transmitter ID codes registered by your SUBARU
dealer. ( →P. 372)
Vehicles with a spare tire of the same wheel type as the
installed tires
Rotate the tires in the order
shown.
To equalize tire wear and
extend tire life, SUBARU rec-
ommends that tire rotation is
carried out at the same inter-
val as tire inspection.
■The tire pressure monitoring system (if equipped)
Your SUBARU is equipped with a tire pressure monitoring sys-
tem that uses tire pressure warning valves and transmitters to
detect low tire inflation pressure before serious problems arise.

■Maximum load of tire
Check that the maximum load of the replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
■Tire types
1Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
2 All season tires All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions, as well as for use
year round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also,
all season tires fall short in acceleration and handling performance
compared with summer tires in highway driving.
3 Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations for possible restriction. Snow tires
should be installed on all wheels. ( →P. 274)
For the GAWR, see the Certification
Label. For the maximum load of the
tire, see the load limit at maximum cold
tire inflation pressure mentioned on the
sidewall of the tire. (
→P. 505)

■Initializing the tire pressure monitoring system (if equipped)
Initialize the system with the tire inflation pressure adjusted to the speci-
fied level.
■Routine tire inflation pressure checks (vehicles with a tire pressure
monitoring system)
The tire pressure monitoring system does not replace routine tire infla-
tion pressure checks. Make sure to check tire inflation pressure as part
of your routine of daily vehicle checks.
■Tire pressure monitoring system certification (if equipped)

CAUTION
■Repairing or replacing tires, wheels, tire pressure warning valves,
transmitters and tire valve caps (vehicles with a tire pressure moni-
toring system)
●When removing or fitting the wheels, tires or the tire pressure warning
valves and transmitters, contact your SUBARU dealer as the tire pres-
sure warning valves and transmitters may be damaged if not handled
correctly.
●When replacing tire valve caps, do not use tire valve caps other than
those specified. The cap may become stuck.
■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.
■Driving on rough roads
Take particular care when driving on roads with loose surfaces or pot
holes.
These conditions may cause losses in tire inflation pressure, reducing
the cushioning ability of the tires. In addition, driving on rough roads may
cause damage to the tires themselves, as well as the vehicle’s wheels
and body.
■Low profile tires and wheels
Low profile tires may cause greater damage than usual to the wheel
when receiving impact from the road surface. Therefore pay attention to
the following:
●Be sure to use proper tire inflation pressure. If tires are under-inflated,
they may be damaged more severely.
●Avoid pot holes, uneven pavement, curbs and other road hazards.
Failure to do so may lead to severe tire and wheel damage.
