7. Remove the wheel nuts and change tires.
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 thetop bolt started through its hole. Wigglethe tire and press it back over the other bolts.Before putting on wheels, 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. Therefore
after the first 1600 km (1000 miles), check
to see that the wheel nuts are tight.8. Reinstall all the wheel nuts finger tight.
Reinstall the wheel nuts (tapered end in-
ward) and tighten them as much as youcan by hand. Press back on the tire back and see if you can tighten them more.

9. Lower the vehicle completely and
tighten the wheel nuts.
Turn the jack handle extension counter-
clockwise with handle to lower the vehicle,
making sure the handle remains firmly
fitted onto the jack handle extension.
Use only the wheel nut wrench and turn it
clockwise to tighten the nuts. Do not use other tools or any additional leverage oth-
er 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 a time in the order
shown. Repeat the process until all the
nuts are tight.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.
Take due care in handling the orna- ment to avoid unexpected personal
injury. CAUTION
! 11. Check the air pressure of the re-
placed tire.
Adjust
the air pressure to the specification
designated in Part 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 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 thetorque specified in Part 8 with a torque wrench, and have a technician repair the flat tire.
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 suddenbraking. CAUTION

Two-wheel drive modelsFour-wheel drive modelsIf towing is necessary, we recommend
you to have it done by your Toyota
dealer or a commercial tow truck ser-vice. Proper equipment will help ensure that your vehicle is not damaged while being
towed. Commercial operators are gener-
ally
aware of the state/provincial and local
laws pertaining to towing.
Your vehicle can be damaged if it is towed
incorrectly. Although most operatorsknow 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.

All modelsÐ
(c) Towing with sling type truck fromrear
NOTICE
Do not tow with sling type truck. This may cause body damage.
If towing service is not available in an
emergency, your vehicle may be tem-
porarily towed by a cable secured to
the emergency towing hook under the
front of the vehicle. 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 andbrakes must all be in good condition. Before towing, release the parking brake
and put the transmission in neutral
(manual) or Nº (automatic). The key must
be in ACCº (engine off) or ONº (enginerunning).
CAUTION!
If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual.
ÐEmergency towing

Before emergency towing, check that the hook installation bolts are not loose.
Fasten the towing rope or cable se-curely to the hook.
Do not jerk the hook.
To avoid damaging the hook, do not
pull from the side or at a vertical angle.
Always pull straight ahead.

If your keys are locked in the vehicle and
you cannot get a duplicate, many Toyota
dealers
can still open the door for you, us-
ing their special tools. If you must break a
window to get in, we suggest breaking the
smallest side window because it is the least expensive to replace. Be extremely cautious to avoid cuts from the glass.

High pressure water or steam is effec-
tive for cleaning the vehicle's under-
side and wheel housings. Pay particu-
lar attention to these areas as it is
difficult to see all the mud and dirt. It
will do more harm than good to simply
wet the mud and debris without remov-
ing them. The lower edge of doors,
rocker panels and frame members
have drain holes which should not be
allowed to clog with dirt as trapped wa-
ter in these areas can cause corrosion.
Wash the underside of the vehicle
thoroughly when winter is over.
See Washing and waxing your Toyotaº
for more tips.
Check the condition of your vehicle's
paint and trim. If you find any chips or
scratches in the paint, touch them up im- mediately to prevent corrosion from start- ing. If the chips or scratches have gone
through the bare metal, have a qualified
body shop make the repair. Check the interior of your vehicle.
Wa-
ter and dirt can accumulate under the floor
mats and could cause corrosion. Occa-
sionally check under the mats to make sure the area is dry. Be particularly careful
when transporting chemicals, cleansers,
fertilizers, salt, etc.; these should be
transported in proper containers. If a spill
or leak should occur, immediately clean
and dry the area.
Use mud shields on your wheels. If you
drive on salted or gravel roads, mud
shields help protect your vehicle. Full- size shields, which come as near to the
ground as possible, are the best. We rec-
ommend that the fittings and the area
where the shields are installed be treated
to resist corrosion. Your Toyota dealer will
be happy to assist in supplying and instal-
ling the shields if they are recommended for your area. Do not park your vehicle in a damp, poorly ventilated garage.
If you wash
your vehicle in the garage, or if you drive
it in covered with water or snow, your ga- rage may be so damp it will cause corro-
sion. Even if your garage is heated, a wet
vehicle can corrode if the ventilation is
poor.

Washing your Toyota by hand
Work in the shade and wait until the ve-
hicle body is not hot to the touch.
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the un-
derside of the vehicle or in the wheel wells.
2. Wash with a mild car-wash soap, mixed
according to the manufacturer's in-
structions. Use a soft cotton mitt and keep it wet by dipping it frequently into the wash
water. Do not rub hardÐlet the soap and water remove the dirt. Aluminum wheels: Use only a mild soap or
neutral detergent.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted surfaces.
Do not use gasoline or strong
solvents, which may be toxic or
cause damage.
NOTICE
3. Rinse thoroughlyÐdried soap can
cause streaking. In hot weather you may need to rinse each section right after you wash it. 4. To prevent water spots, dry the vehicle using a clean soft cotton towel. Do not rub
or press hardÐyou might scratch thepaint.
Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some type of
brushes, unfiltered washing water, or the
washing process itself. Scratching re- duces
paint durability and gloss, especial-
ly on darker colors. The manager of the car wash should be able to advise you whether the process is safe for the paint
on your vehicle.
Waxing your Toyota
Polishing and waxing is recom-
mended to maintain the original
beauty of your Toyota's finish.
1. Always wash and dry the vehicle be-
fore you begin waxing, even if you are us-
ing a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has become extremely weath-
ered, use a car-cleaning polish, followed
by a separate wax. Carefully follow the
manufacturer 's instructions and precau-
tions. Be sure to polish and wax the chrome trim as well as the paint. 3. Wax the vehicle again when water
does
not bead but remains on the surface
in large patches.
