To store the jack, align the hole of the
jack head with the vehicle hook. Turn the
jack joint until the jack base fits securely
with the vehicle body.
This prevents the jack from flying forward
during a collision or sudden stop.To remove the spare tire:
1. Loosen the nut and remove it.
2. Remove the spare tire cover.
3. Loosen the bolt and remove it.
4. Remove the spacer. (compact spare tire only)
Then take the spare tire out of the ve-
hicle.
When storing the spare tire, put it in place
with the outer side of the wheel facing up.
Then secure the tire by repeating the
above removal steps in reverse order to
prevent it from flying forward during a
collision or sudden braking.2. Block the wheel diagonally opposite the flat tire to keep the vehicle from
rolling when it is j acked up.
When blocking the wheel, place a wheel
block in front of one of the front wheels
or behind one of the rear wheels.

CAUTION
Never use oil or grease on the bolts
or nuts. Doing so may lead to over-
tightening the nuts and damaging the
bolts. The nuts may loose and the
wheels may fall off, which could cau-
se a serious accident. If there is oil
or grease on any bolt or nut, clean
it.
9. Lower the vehicle completely andtighten 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 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.
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 103 N·m (10.5
kgf·m, 77 ft·lbf), as soon as pos-
sible after changing wheels. Other-
wise, the nuts may loosen and the
wheels may fall off, which could
cause a serious accident.

10. Reinstall the wheel ornament.1. Put the wheel ornament into position.
Align the cutout of the wheel ornament
with the valve stem as shown. 2. Tap it firmly with the side or heel of your hand to snap it into place.
CAUTION
Take due care in handling the orna-
ment to avoid unexpected personal
injury.
11. Check the air pressure of the re- placed tire.
Adjust the air pressure to the specification
designed on page 290 in Section 8. If the
pressure is lower, drive slowly to the
nearest service station and fill to the cor-
rect pressure.
Do not forget to reinstall the tire inflation
valve cap as dirt and moisture could get
into the valve core and possibly cause air
leakage. If the cap is missing, have a new
one put on as soon as possible.
12. Restow all the tools, jack and flat tire securely.
As soon after changing wheels as pos-
sible, tighten the wheel nuts to the torque
specified on page 290 in Section 8 with
a torque wrench. Have a technician repair
the flat tire and replace the spare tire with
it.
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 in-
jury during a collision or s udden
braking.
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.
Vehicles with traction control system—
Turn off the traction control system to
become unstuck to allow the tires to
spin enough to remove the vehicle from
the obstruction. (For details, see “Trac-
tion control system” on page 124 in
Section 16.)
CAUTION
Do not attempt to rock the vehicle
free by moving it forward and back-
ward if people or objects are any-
where 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 ob-
jects.
