6. Raise the jack by turning the
wheel wrench clockwise until the
slots in the jack head fit into the
metal flange located behind the
V shaped locating notches on
the plastic molding as shown.
7. Put the compact spare tire
near you.
8. Raise the vehicle by turning the
wheel wrench clockwise. Raise
the vehicle far enough off the
ground for the compact spare
tire to fit under the vehicle.
9. Remove all of the wheel nuts
and the flat tire.
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, a cloth or a
paper towel can be used;
however, use a scraper or wire
brush later to remove all rust
or dirt.
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.
