To remove the spare tire:
1. Raise the luggage compartment floor.
2. On vehicles with compact spare tire,
take the tool holder with tools out.
3. Loosen the bolt with spacer and re-
move it.
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.
—Blocking the wheel
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 from the front for the front wheels
or from the rear for the rear wheels.

Before putting on wheels, remove any cor-
rosion 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. Therefore after the
first 1600 km (1000 miles), check to see
that the wheel nuts are tight.
—Reinstalling wheel nuts
8. Reinstall all the wheel nuts finger
tight.
Reinstall the wheel nuts (tapered end in-
ward) and tighten them as much as you
can by hand. Press back on the tire and
see if you can tighten them more.
—Lowering your vehicle
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 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.

—After changing wheels
11. Check the air pressure of the re-
placed tire.
Adjust the air pressure to the specification
designed in part 8. If the pressure is low-
er, drive slowly to the nearest service sta-
tion and fill to the correct 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 as possible after changing
wheels, tighten the wheel nuts to the
torque specified in Part 8 with a torque
wrench and have a technician repair the
flat tire.
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 sudden
braking.
(a) Towing with wheel lift type truck—
—From front
—From rear
(b) Using flat bed truck
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice. In consultation with them, have
your vehicle towed using either (a) or
(b).
Only when you cannot receive a towing
service from a Toyota dealer or com-
mercial tow truck service, tow your ve-
hicle carefully in accordance with the
instructions given in ”—Emergency tow-
ing” in this Part.
Proper equipment will help ensure that
your vehicle is not damaged while being
towed. Commercial operators are generally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is
towed incorrectly. Although most operators
know the correct procedure, it is possible
to make a mistake. To avoid damage to
your vehicle, make sure the following few
precautions are observed. If necessary,
show this page to the tow truck driver.
TOWING PRECAUTIONS:
Use a safety chain system for all towing,
and abide by the state/provincial and local
laws. The wheels and axle on the ground
must be in good condition. If they are
damaged, use a towing dolly.

—Emergency towing
If towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-
vice.
If towing service is not available in an
emergency, your vehicle may be tempo-
rarily towed by a cable or chain se-
cured to the emergency towing eyelet
under the vehicle. Use extreme caution
when towing vehicles.
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 ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing eyelets and towing cable or
chain. The eyelets 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 eyelets provided.
Before towing, release the parking brake
and put the transmission in neutral (manu-
al) or ”N” (automatic). The key must be
in ”ACC” (engine off) or ”ON” (engine run-
ning).
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.
