above. Grab the wrench near the end of the handle
and pull up on the handle. Be careful that the wrench
does not slip off the nut.
Do not remove the nuts yet Ð just unscrew them
about one-half turn.

6. After making sure no one is in the vehicle, raise
it high enough so that the spare tire can be
installed.
Allow for the fact that you need more ground
clearance when putting on the spare tire than when
removing the flat tire.
To raise the vehicle, insert the jack handle extension
into the jack (it is a loose fit) and turn it clockwise
with the handle, making sure the handle remains firmly
fitted onto the jack handle extension. As the jack
touches the vehicle and begins to lift, double-check
that it is properly positioned.
CAUTION
Never get under the vehicle when the vehicle
is supported by the jack alone.
7. Remove the wheel nuts and remove the flat tire.
Lift the flat tire straight off and put it aside.
Roll the spare wheel into position and align the holes
in the wheel with the bolts. Then lift up the wheel
and get at least the top bolt started through its hole.
Wiggle the tire and press it back over the other bolts.

IN CASE OF AN EMERGENCY

Before putting on the wheel, remove any corrosion
on the mounting surfaces with a wire brush or such.
Installation of wheels without good metal-to-metal
contact at the mounting surface can cause wheel nuts
to loosen and eventually cause a wheel to come off
while driving.8. Reinstall all the wheel nuts finger tight.
Reinstall the wheel nuts and tighten them as much
as you can by hand. Press the tire back and see
if you can tighten them more.
CAUTION
Never use oil or grease on the bolts or nuts.
Doing so may lead to overtightening the nuts
and damaging the bolts. The nuts may loose and
the wheels may fall off, which could cause a
serious accident. If there is oil or grease on any
bolt or nut, clean it.

9. Lower the vehicle completely and tighten the
wheel nuts.
To lower the vehicle, turn the jack handle extension
counterclockwise with the handle, making sure the
handle remains firmly fitted onto the jack handle
extension.
Use only the wheel nut wrench to tighten the nuts.
Do not use other tools or any additional leverage other
than your hands, such as a hammer, pipe or your foot.
Make sure the wrench is securely engaged over the
nut.
Tighten each nut a little at a time in the order shown.
Repeat the process until all the nuts are tight.
CAUTION
When lowering the vehicle, make sure all
portions of your body and all other persons
around will not be injured as the vehicle is
lowered to the ground.
Have the wheel nuts tightened with torque
wrench to 112 N´m (11.5 kgf´m, 83 ft´lbf), as
soon as possible after changing wheels.
Otherwise, the nuts may loosen and the
wheels may fall off, which could cause a
serious accident.
