3. Place the jack at the position marked
with a half circle.
4. Place the hex tube end of the wrench
over the hex head of the jack to
attach it.
5. Turn the wheel wrench clockwise until
the lift head is firmly contacting the
proper lifting point nearest the flat tire.
Warning
Getting under a vehicle when it is lifted
on a jack is dangerous. If the vehicle slips
off the jack, you could be badly injured
or killed. Never get under a vehicle when
it is supported only by a jack.
Warning
Raising the vehicle with the jack
improperly positioned can damage the
vehicle and even make the vehicle fall. To
help avoid personal injury and vehicle
damage, be sure to fit the jack lift head
into the proper location before raising
the vehicle.
Warning
Lifting a vehicle and getting under it to
do maintenance or repairs is dangerous
without the appropriate safety equipment
and training. If a jack is provided with
the vehicle, it is designed only for
changing a flat tire. If it is used for
anything else, you or others could be
badly injured or killed if the vehicle slips
off the jack. If a jack is provided with the
vehicle, only use it for changing a
flat tire.
6. Turn the wheel wrench clockwise to raise
the vehicle far enough off the ground so
there is enough room for the spare tire
to fit underneath the wheel well.
7. Turn the wheel nuts counterclockwise to
remove them.
8. Remove the flat tire.
Warning
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 a crash. 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.
