[Vehicle with aluminum wheels]
• Normal wheels
Temporarily tighten the wheel nuts (flange nuts) until
their flange section comes in contact with the wheel and it
is no longer loose.
• Compact spare wheel
Install the wheel nuts with their tapered ends facing
inward, then tighten by hand until the wheel is no longer
loose.
CAUTION
!
Never apply oil to either the wheel bolts or the nuts
or they will tighten too much.
NOTE
Flange nuts can be temporarily used on the compact spare
or steel wheel, but return them to the original wheel and
tire as soon as possible.
If all four wheels are changed to steel wheels, use tapered
nuts.
