Buick 2009 Enclave - Manual (Page 352)

{ CAUTION:
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after time. The wheel could come off and cause an
accident. When changing a wheel, remove any rust
or dirt from places where the wheel attaches to the
vehicle. In an emergency, use a cloth or a paper
towel to do this; but be sure to use a scraper or wire
brush later, if needed, to get all the rust or dirt off.
See Changing a Flat Tire on page 5-76.
7. Remove any rust or dirt
from the wheel bolts,
mounting surfaces, and
spare wheel.
8. Install the compact spare tire.
{ CAUTION:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle’s wheel
could fall off, causing a crash.
9. Put the wheel nuts back on with the rounded end of
the nuts toward the wheel. Turn each nut clockwise
by hand until the wheel is held against the hub.
10. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
