4466-3. Do-it-yourself maintenance
■When replacing wheels
The wheels of your vehicle are equipped with tire pressure warn ing
valves and transmitters that allow the tire pressure warning sy stem to
provide advance warning in the event of a loss in tire inflatio n pressure.
Whenever wheels are replaced, tir e pressure warning valves and trans-
mitters must be installed. ( P. 427)
■When installing the wheel o rnament (on some models)
WARNING
■When replacing wheels
●Do not use wheels that are a different size from those recommen ded in
the Owner’s Manual, as this may result in a loss of handling control.
●Never use an inner tube in a leaking wheel which is designed fo r a
tubeless tire. Doing so may resu lt in an accident, causing death or seri-
ous injury.
■When installing the wheel nuts
●Be sure to install the wheel nuts with the tapered ends facing inward.
(  P. 515) Installing the nuts with th e tapered ends facing outward can
cause the wheel to break and ev entually cause the wheel to come off
while driving, which could lead to an accident resulting in dea th or seri-
ous injury.
●Never use oil or grease on the wheel bolts or wheel nuts.
Oil and grease may cause the wheel nuts to be excessively tight ened,
leading to bolt or disc wheel damage. In addition, the oil or g rease can
cause the wheel nuts to loosen and the wheel may fall off, caus ing an
accident and resulting in death or serious injury. Remove any oil or
grease from the wheel bolts or wheel nuts.
Align the notch of the wheel and orna-
ment.
