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.

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.

10. Reinstall the wheel ornament.
Put the wheel ornament into position and then tap it
firmly with the side or heel of your hand to snap it
into place.
CAUTION
Take due care in handling the ornament to avoid
unexpected personal injury.
11. After changing the wheel, check the air
pressure of the replaced tire. Stow all the tools,
jack and flat tire securely.
If the pressure of the replaced tire is low, drive slowly
to the nearest service station and fill to the correct
pressure.Do not forget to reinstall the tire valve cap as dirt and
moisture could get into the valve core and possible
cause air leakage. If the cap is missing, put a new
one on as soon as possible.
This is the same procedure for changing or rotating
your tires.
CAUTION
Before driving, make sure all the tools, jack and
flat tire are securely in place in their storage
location to reduce the possibility of personal
injury during a collision or sudden braking.

clues are:

Engine missing, stumbling, or pinging

Appreciable loss of power

Strange engine noises

A fluid leak under the vehicle (However, water dripping from
the air conditioning after use is normal.)

Change in exhaust sound (This may indicate a dangerous
carbon monoxide leak. Drive with the windows open and
have the exhaust system checked immediately.)

Flat-looking tires, excessive tire squeal when cornering,
uneven tire wear

Vehicle pulls to one side when driving straight on a level
road

Strange noises related to suspension movement

Loss of brake effectiveness, spongy feeling brake pedal,
