When driving
BRZ_U (A4450BE-A)
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.

BRZ_U (A4450BE-A)
■Refueling in cold weather
To help prevent moisture from forming in the fuel system and the risk of its
freezing, use of an antifreeze additive in the fuel tank is recommended dur-
ing cold weather.
Use only additives that are specifically designed for this purpose. When an
antifreeze additive is used, its effect lasts longer if the tank is refilled when-
ever the fuel level reaches half empty.
WARNING
■Driving with snow tires
Observe the following precautions to reduce the risk of accidents.
Failure to do so may result in a loss of vehicle control and cause death or
serious injury.
●Use tires of the specified size, and that are the same for the following
items:
•Size
• Circumference
• Speed symbol
• Load index
• Construction
• Manufacturer
• Brand (tread pattern)
• Degrees of wear
●Maintain the recommended level of air pressure.
●Use snow tires on all, not just some wheels.

CAUTION
■Repairing or replacing snow tires (vehicles with a tire pressure moni-
toring system)
Request repairs or replacement of snow tires from SUBARU dealers or
legitimate tire retailers.
This is because the removal and attachment of snow tires affects the
operation of the tire pressure warning valves and transmitters.
■Fitting tire chains (vehicles with a tire pressure monitoring system)
The tire pressure warning valves and transmitters may not function cor-
rectly when tire chains are fitted.

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.

Tires
Replace or rotate tires in accordance with maintenance sched-
ules and treadwear.
■Checking tires
New tread
Treadwear indicator
Worn tread
The location of treadwear
indicators is shown by the
“TWI” or “ ” marks, etc.,
molded on the sidewall of
each tire.
Check spare tire condition
and pressure if not rotated.
■Tire rotation
Vehicles with a compact spare tire
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.

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. 376)
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.
