2016 SUBARU BRZ maintenance

316 4-3. Do-it-yourself maintenance
■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)
MODEL/FCC IDs:
Transmitter: PAXPMVC010
Receiver: HYQ23AAA (vehicles without a keyless access with push
button start system)
HYQ23AAE (vehicles with a keyless access with push but-
ton start system)
NOTE:
This device complies with part 15 of the FCC Rules. Operation is subject
to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
FCC WARNING:
Changes or modifications not expressly approved by the party responsi-
ble for compliance could void the user's authority to operate the equip-
ment.

Maintenance and care
WARNING
■Tire pressure monitoring system operation (if equipped)
The tire pressure monitoring system may not provide warning immedi-
ately if a tire bursts or if sudden air leakage occurs.
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train, as well as
dangerous handling characteristics, which may lead to an accident
resulting in death or serious injury.
●Make sure to install 4 tires that are of the specified size, and that all 4
tires are the same for the following items:
•Size
• Circumference
• Speed symbol
• Load index
• Construction
• Manufacturer
• Brand (tread pattern)
• Degrees of wear
You must obey the specification printed on the tire placard. The tire plac-
ard is located on the driver's door pillar.
If all four tires are not the same in items listed above, there is a possibil-
ity that it may lead to serious mechanical damage to the drive train of
your car and affect the following.
•Ride
• Handling
•Braking
• Speedometer/Odometer calibration
• Clearance between the body and the tires
It also may be dangerous and lead to loss of vehicle control as well as an
accident.
●Only use radial tires.
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.

318 4-3. Do-it-yourself maintenance
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.
■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.
■If tire inflation pressures become low while driving
Do not continue driving, or your tires and/or wheels may be ruined.

Maintenance and care
Tire inflation pressure
■Tire inflation pressure
The recommended cold tire inflation pressure and tire size is dis-
played on the tire and loading information label. (oP. 424)

320 4-3. Do-it-yourself maintenance
■Tire inflation pressure check interval
You should check tire inflation pressure every two weeks, or at least
once a month.
Do not forget to check the spare.
■Inspection and adjustment procedure
Tire valve
Tire pressure gauge
Remove the tire valve cap.
Press the tip of the tire pressure gauge onto the tire valve.
Read the pressure using the graduations of the gauge.
If the tire inflation pressure is not within the recommended
levels, adjust the pressure.
If you add too much air, press the center of the valve to
lower.
After completing the tire inflation pressure measurement
and adjustment, apply soapy water to the valve and check
for leakage.
Reinstall the tire valve cap.

Maintenance and care
■Effects of incorrect tire inflation pressure
Driving with incorrect tire inflation pressure may result in the following:
●Reduced fuel economy
●Reduced driving comfort and poor handling
●Reduced tire life due to wear
●Reduced safety
●Damage to the drive train
If a tire needs frequent refilling, have it checked by your SUBARU dealer.
■Instructions for checking tire inflation pressure
When checking tire inflation pressure, observe the following:
●Check only when the tires are cold.
If your vehicle has been parked for at least 3 hours and has not been
driven for more than 1 mile or 1.5 km, you will get an accurate cold
tire inflation pressure reading.
●Always use a tire pressure gauge.
It is difficult to judge if a tire is properly inflated based only on its
appearance.
●It is normal for the tire inflation pressure to be higher after driving as
heat is generated in the tire. Do not reduce tire inflation pressure after
driving.
●Never exceed the vehicle capacity weight.
Passengers and luggage weight should be placed so that the vehicle
is balanced.

322 4-3. Do-it-yourself maintenance
WARNING
■Proper inflation is critical to save tire performance
Keep your tires properly inflated.
If the tires are not properly inflated, the following conditions may occur
which could lead to an accident resulting in death or serious injury:
●Excessive wear
●Uneven wear
●Poor handling
●Possibility of blowouts resulting from overheated tires
●Air leaking from between tire and wheel
●Wheel deformation and/or tire damage
●Greater possibility of tire damage while driving (due to road hazards,
expansion joints, sharp edges in the road, etc.)
CAUTION
■When inspecting and adjusting tire inflation pressure
Be sure to reinstall the tire valve caps.
If a valve cap is not installed, dirt or moisture may get into the valve and
cause an air leak, resulting in decreased tire inflation pressure.

Maintenance and care
Wheels
If a wheel is bent, cracked or heavily corroded, it should be
replaced. Otherwise, the tire may separate from the wheel or
cause loss of handling control.
■Wheel selection
When replacing wheels, care should be taken to ensure that
they are equivalent to those removed in load capacity, diameter,
rim width, and inset
*.
Replacement wheels are available at your SUBARU dealer.
*: Conventionally referred to as “offset”.
SUBARU does not recommend using:
●Wheels of different sizes or types
●Used wheels
●Bent wheels that have been straightened
■Aluminum wheel precautions
●Use only SUBARU wheel nuts and wrenches designed for
use with your aluminum wheels.
●When rotating, repairing or changing your tires, check that the
wheel nuts are still tight after driving 1000 miles (1600 km).
●Be careful not to damage the aluminum wheels when using
tire chains.
●Use only SUBARU genuine balance weights or equivalent
and a plastic or rubber hammer when balancing your wheels.
