4. After the tire is lowered completely to the ground,
remove the holding bracket.
CAUTION
Do not take out the spare tire from under the
vehicle until it is lowered completely to the
ground. When removing the spare tire, take care
that fingers are not pinched between the wheel
and holding bracket.
When storing the spare tire, place it with the outer
side of the wheel facing up. Then secure the tire,
taking care that the tire goes straight up without
catching on any other part, to prevent it from flying
forward during a collision or sudden braking.

Vehicles with kinetic dynamic suspension system Ð
When raising the spare tire, pull the tire toward the
rear of the vehicle. After raising the tire, visually check
that the tire does not interfere with the suspension
components. If interference occurs, lower the spare
tire and start again.
NOTICE
Tighten the spare tire clamp bolt to hold the
spare wheel carrier by the hook securely.
Vehicles with kinetic dynamic suspension
system Ð Make sure that the spare tire does
not interfere with the suspension components
when the spare tire is stowed. If interference
occurs, the suspension system will be
damaged.

2. Block the wheel diagonally opposite the flat tire
to keep the vehicle from rolling when it is jacked
up.
When blocking the wheel, place a wheel block in front
of one of the front wheels or behind one of the rear
wheels.3. Remove the wheel ornament.
Pry off the wheel ornament, using the beveled end
of the wheel ornament remover as shown.

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 them.
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 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.
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 accident.

3Jack handle extension without bolt
4Jack handle
Put a jack handle, jack handle extensions and jack
handle end together as shown in the illustration.
CAUTION
Make sure they are securely fixed with the
screws.
When connecting a jack handle extension with a jack
handle end, use a Phillips-head screwdriver or jack
handle to tighten the bolts on the joints as shown in
the illustration. When connecting the jack handle with
extension, tighten the bolt on the jack handle securely.
Make sure the hollow meets the bolt on any joint when
you tighten the bolts.
NOTICE
Tighten all the joints securely. Otherwise, the
extension may come off and it may damage the
paint or vehicle body.

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
480
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.

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.

IF YOUR VEHICLE BECOMES
STUCK
If your vehicle becomes stuck in snow, mud, sand, etc.,
then you may attempt to rock the vehicle free by moving
it forward and backward.
In this situation, lock the center differential and turn off the
vehicle stability control system. (For details, see
Four-wheel drive systemº on page 384.)
CAUTION
Do not attempt to rock the vehicle free by moving it
forward and backward if people or objects are anywhere
near the vehicle. During the rocking operation the
vehicle may suddenly move forward or backward as it
becomes unstuck, causing injury or damage to nearby
people or objects.
NOTICE
If you rock your vehicle, observe the following
precautions to prevent damage to the transmission and
other parts.
Do not depress the accelerator pedal while shifting
the selector lever or before the transmission is
completely shifted to forward or reverse gear.
Do not race the engine and avoid spinning the
wheels.
If your vehicle remains stuck after rocking the vehicle
several times, consider other ways such as towing.
