When Replacing Wheels; When Installing The Wheel Nuts - Subaru 2014 BRZ Owner's Manual

When replacing wheels (vehicles with a tire pressure monitoring
I
system)
The wheels of your SUBARU are equipped with tire pressure warning
valves and transmitters that allow the tire pressure monitoring system to
provide advanced warning in the event of a loss in tire inflation pressure.
Whenever wheels are replaced, the tire pressure warning valves and
transmitters must be installed. ( P. 311)
WARNING

When replacing wheels

I
Do not use wheels that are a different size from those recommended in
G
the Owner’' s Manual, as this may result in loss of handling control.
Never use an inner tube in a leaking wheel which is designed for a
G
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.

When installing the wheel nuts

I
Tapered portion
Never use oil or grease on the wheel bolts or wheel nuts.
G
Oil and grease may cause the wheel nuts to be excessively tightened,
leading to bolt or disc wheel damage. In addition, the oil or grease can
cause the wheel nuts to loosen and the wheel may fall off, causing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
4-3. Do-it-yourself maintenance
Be sure to install the wheel nuts with
G
the tapered ends facing inward.
Installing the nuts with the tapered
ends facing outward can cause the
wheel to break and eventually cause
the wheel to come off while driving,
which could lead to an accident
resulting in death or serious injury.
