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 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 extension coun-
terclockwise with handle to lower the
vehicle, making sure the handle re-
mains firmly fitted onto the jack han-
dle extension.
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.

11. Check the air pressure of the re-placed tire.
Adjust the air pressu re to the specifi-
cation designated on page 466 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.
12.Restow all the tools, jack and flat tire securely.
With a spare tire of the same wheel
type as the installed tires—
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 466 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire. With a spare tire of different wheel
type from the installed tires—
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 466 in Sec-
tion 8 with a torque wrench. Have a
technician repair the flat tire and re-
place the spare tire with it.
Initial adjustment of the tire pres-
sure warning system is necessary
after you have replaced your tires
or wheels. See “Tire pressure
warning system” on page 200 in
Section 17.
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.
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.
Twowheel drive models—Turn off the
traction control system to become un-
stuck to allow the tires to spin enough
to remove the vehicle from the obstruc-
tion. For details, see “Traction control
system” on page 184 in Section 17.
Fourwheel drive models—Lock the cen-
ter differential to become unstuck. For
details, see “Fourwheel drive system”
on page 179 in Section 17.
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.

A driver must be in the vehicle to steer
it and operate the brakes.
Towing in this manner may be done only
on hard−surfaced roads for a short dis-
tance and at low speeds. Also, the
wheels, axles, drive train, steering and
brakes must all be in good condition.
CAUTION
Use extreme caution when towing the
vehicle. Avoid sudden starts or errat-
ic driving maneuvers which would
place excessive stress on the emer-
gency towing hook and towing cable
or chain. The hook and towing cable
or chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing hook provided.
Before towing, release the parking brake,
put the transmission in “N” and as to the
four −wheel drive models, moreover, set
the transfer in “2WD” mode. The key must
be in “ACC” (engine off) or “ON” (engine
running).
CAUTION
If the engine is not running, the pow-
er assist for the brakes and steering
will not work so steering and braking
will be much harder than usual.
Before emergency towing, check that
the hook is not broken or damaged and
that the installation bolts are not loose.
Fasten the towing cable or chain se-
curely to the hook.
Do not jerk the hook. Apply steady and
even force.
To avoid damaging the hook, do not
pull from the side or at a vertical
angle. Always pull straight ahead.

buckles, retractors and anchors operate
properly and smoothly. Make sure the belt
webbing is not cut, frayed, worn or dam-
aged.
Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
In a safe place, check that the brakes do
not pull to one side when applied. Parking brake

and that, on a safe incline, your vehicle
is held securely with only the parking
brake applied.

nism
On a safe incline, check that your vehicle
is held securely with the selector lever in
“P” position and all brakes released.
OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
specified.
Fluid leaks
Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has
been parked for a while. If you smell fuel
fumes or notice any leak, have the cause
found and corrected immediately.
Doors and engine hood
Check that all doors including back door
operate smoothly and all latches lock se-
