low oil pressure TOYOTA COROLLA 2013 11.G Owners Manual

384 4-3. Do-it-yourself maintenance
■When replacing wheels
The wheels of your Toyota, except for the compact spare tire, are
equipped with tire pressure warning valves and transmitters that allow
the tire pressure warning system to provide advanced warning in the
event of a loss in tire inflation pressure. Whenever wheels are replaced,
the tire pressure warning valves a nd transmitters must be installed.
(  P. 372)
CAUTION
■When replacing wheels
●Do not use wheels that are a different size from those recommended in
the Owner’s Manual, as this may re sult in loss of handling control.
●Never use an inner tube in a leaking wheel which is designed for a
tubeless tire. Doing so may result in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Never use oil or grease on the wheel bolts or wheel nuts.
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.
●Be sure to install the wheel nuts with
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.
