3. Remove the wheel ornament.
Pry off the wheel ornament, using the
beveled end of the wheel nut wrench
as shown.
CAUTION
Do not try to pull off the orna-
ment by hand. Take due care in
handling the ornament to avoid
unexpected personal injury.
4. Loosen all the wheel nuts.
Always loosen the wheel nuts before
raising the vehicle.
Turn the wheel nuts counterclockwise
to loosen. To get maximum leverage,
fit the wrench to the nut so that the
handle is on the right side, as shown
above. Grab the wrench near the end
of the handle and pull up on the han-
dle. Be careful that the wrench does
not slip off the nut.
Do not remove the nuts yet—just un-
screw them about one −half turn.
CAUTION
Never use oil or grease on the
bolts or nuts. The nuts may loose
and the wheels may fall off,
which could cause a serious ac-
cident.

5. Position the jack at the correctjack point as shown.
Make sure the jack is positioned on
a level and solid place.
Jack point guide
With side mud guards—The jack point
guides are located under the side
mud guards. They indicate the jack
point positions.6. After making sure that no one is in the vehicle, raise it high
enough so that the spare tire
can be installed.
Remember you will need more ground
clearance when putting on the spare
tire than when removing the flat tire.
To raise the vehicl e, insert the jack
handle into the jack (it is a loose fit)
and turn it clockwise. As the jack
touches the vehicle and begins to lift,
double −check that it is properly posi-
tioned.

CAUTION
Never get under the vehicle when
the vehicle is supported by the
jack alone.
7. Remove the wheel nuts andchange tires.
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 wheels, remove any
corrosion on the mounting surfaces
with a wire brush or such. Installation
of wheels without good metal− to−met-
al 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 fin-ger tight.
Reinstall the wheel nuts (tapered end
inward) and tighten them as much as
you can by hand. Press back on 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 seri-
ous accident. If there is oil or
grease on any bolt or nut, clean
it.
9. Lower the vehicle completely and tighten the wheel nuts.
Turn the jack handle counterclock-
wise to lower the vehicle.
Use only the wheel nut wrench and
turn it clockwise to tighten the nuts.
Do not use other tools or any addition-
al leverage other than your hands,
such as a hammer, pipe or your foot.
Make sure the wrench is securely en-
gaged over the nut.
Tighten each nut a little at a time in
the order shown. Repeat the process
until all the nuts are tight.

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 103 N·m
(10.5 kgf·m, 77 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.

curely in the luggage storage
box. Then secure the flat tire in
the luggage compartment with
the tire tiedown belts and tie
down hooks as follows.
CAUTION
Before driving, make sure all the
tools, jack and flat tire are se-
curely in place in their storage
location to reduce the possibility
of personal injury during a colli-
sion or sudden braking.

storage box lid. Then pull the ends
of the belts to se cure the tire se-
curely.
After stowing the flat tire, check that
the tire and belts are secured.
To loosen the tire tie −down belts, see
“Tie −down hooks and tire tie −down
belts” on page 178 in Section 1 −10. 11. Check the air pressure of the re-
placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 308 in
Section 8. If the pressure is lower,
drive slowly to the nearest service
station and fill to the correct pressure.
Do not forget to reinstall the tire infla-
tion valve cap as dirt and moisture
could get into th e valve core and
possibly cause air leakage. If the cap
is missing, have a new one put on as
soon as possible.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 308 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire.
