3. Place the jack at the position markedwith a half circle.
4. Place the hex tube end of the wrenchover 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.

crash.
11. Reinstall the wheel nuts. Turn each nut clockwise, by hand, until the wheel is
held against the hub. 12. Lower the vehicle by turning the wheel
wrench counterclockwise. Lower the jack
completely.
{Warning
Wheel nuts that are improperly or
incorrectly tightened can cause the
wheels to become loose or come off. The
wheel nuts should be tightened with a
torque wrench to the proper torque
specification after replacing. Follow the
torque specification supplied by the
aftermarket manufacturer when using
accessory locking wheel nuts. See
Capacities and Specifications 0324 for
original equipment wheel nut torque
specifications.
Caution
Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To
avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper
sequence and to the proper torque
specification. See Capacities and
Specifications 0324 for the wheel nut
torque specification.
13. Tighten the wheel nuts firmly with the wheel wrench in a crisscross sequence, as
shown.
Caution
Wheel covers will not fit on the vehicle's
compact spare. If you try to put a wheel
cover on the compact spare, the cover or
the spare could be damaged.
