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. 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 ± just unscrew them about one±half
turn.
CAUTION
Never use oil or grease on the bolts or nuts. The nuts
may loosen and the wheels may fall off, which could
cause a serious accident.

8. Reinstall all the wheel nuts finger tight.
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.
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 loosen 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.
Turn the jack handle counterclockwise to lower the vehicle.
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.
As soon as possible after changing wheels, have the
wheel nuts tightened by torque wrench at 103 N´m
(10.5 kgf´m, 76 ft´lbf.).
