4. Loosen all the wheel nuts.
Always loosen the wheel nuts before rais-
ing the vehicle.
Turn the wheel nuts counterclockwise to
loosen. 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 onehalf turn.5. Position the jack at the correct jack point as shown.
Make sure the jack is positioned on a
level and solid place.6. After making sure that no one is in the vehicle, raise it high enough so
that the spare tire can be installed.
Remember you will need more ground
clearance when putting on the spare tire
than when removing the flat tire.
To raise the vehicle, insert the jack handle
into the jack (it is a loose fit) and turn it
clockwise. As the jack touches the vehicle
and begins to lift, doublecheck that it is
properly positioned.

CAUTION
Never get under the vehicle when the
vehicle is supported by the jack
alone.
7. Remove the wheel nuts and changetires.
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 the
top bolt started through its hole. Wiggle
the tire and press it back over the other
bolts.Before putting on wheels, remove any cor-
rosion on the mounting surfaces with a
wire brush or such. Installation of wheels
without good metaltometal 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 fingertight.
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.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.
CAUTION
When lowering the vehicle, make sure
all portions of your body and all oth-
er persons around will not be injured
as the vehicle is lowered to the
ground.

10. Reinstall the wheel ornament.1. Put the wheel ornament into position.
On some models, align the cutout of the
wheel ornament with the valve stem as
shown. 2. Then 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 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 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 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.

OUTSIDE THE VEHICLE
Items listed below should be performed
from time to time, unless otherwise
specified.
Tire pressure
Check the pressure with a gauge every
two weeks, or at least once a month. See
Section 72 for additional information.Tire surface and wheel nuts
Check the tires carefully for cuts, damage
or excessive wear. See Section 72 for
additional information. When checking the
tires, make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary.
Tire rotation
Rotate the tires according to the mainte-
nance schedule. (For scheduled mainte-
nance information, please refer to the
“Scheduled Maintenance Guide” or “Own-
er ’s Manual Supplement”.) See Section
72 for additional information.

Power steering fluid level
Check the level through the reservoir. The
level should be in the “HOT” or “COLD”
range depending on the fluid temperature.
See Section 72 for additional information.
Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have
the cause located and corrected immedi-
ately. (See “Engine exhaust cautions” in
Section 2.)Be on the alert for changes in perfor-
mance, sounds, and visual tipoffs that
indicate service is needed. Some impor-
tant clues are as follows:
Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monoxide
leak. Drive with the windows open and
have the exhaust system checked im-
mediately.)
Flatlooking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving
straight on a level road
Strange noises related to suspension
movement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal;pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continually
higher than normalIf you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.

Clean all dirt from outside of the reservoir
tank and look at the fluid level. If the fluid
is cold, the level should be in the “COLD”
range. Similarly, if it is hot, the fluid level
should be in the “HOT” range. If the level
is at the low side of either range, add
automatic transmission fluid DEXRON
II or III to bring the level within the range.
To remove the reservoir cap, turn it coun-
terclockwise and lift up. To reinstall it,
turn it clockwise. After replacing the reser-
voir cap, visually check the steering box
case, vane pump and hose connections
for leaks or damage.
CAUTION
The reservoir tank may be hot so be
careful not to burn yourself.
NOTICE
Avoid overfilling, or the power steer-
ing could be damaged.
Keep your tire pressures at the proper
level.
The recommended cold tire pressures, tire
size and the vehicle capacity weight are
given in Section 8. They are also on the
tire pressure label as shown.
You should check the tire pressures every
two weeks, or at least once a month. And
don’t forget the spare!
Incorrect tire pressure can reduce tire
life and make your vehicle less safe to
drive. Low tire pressure results in excessive
wear, poor handling, reduced fuel econo-
my, and the possibility of blowouts from
overheated tires. Also, low tire pressure
can cause poor sealing of the tire bead.
If the tire pressure is excessively low,
there is the possibility of w
heel deforma-
tion and/or tire separation.
High tire pressure produces a harsh ride,
handling problems,excessive wear at the
center of the tire tread, and a greater
possibility of tire damage from road haz-
ards.
If a tire frequently needs ref illing, have it
checked by your Toyota dealer.
The following instructions for checking
tire pressure should be observed:
The pressure should be checked only
when the tires are cold. If your ve-
hicle has been parked for at least 3
hours and has not been driven for
more than 1.5 km or 1 mile since, you
will get an accurate cold tire pressure
reading.
Always use a tire pressure gauge.
The appearance of a tire can be mis-
leading. Besides, tire pressures that
are even just a few pounds off can
degrade ride and handling.
Checking tire pressure

’02 Corolla U (L/O 0105)
2192002 Corolla_U (OM12743U)
Take special care when adding air to
the compact spare tire. The smaller
tire size can gain pressure very quick-
ly. Add compressed air in small quanti-
ties and check the pressure often until
it reaches the specified pressure.
Do not bleed or reduce tire pressure
after driving. It is normal for the tire
pressure to be higher after driving.
Never exceed the vehicle capacity
weight. The passenger and luggage
weight should be located so that the
vehicle is balanced.
Be sure to reinstall the tire inflation
valve caps. Without the valve caps,
dirt or moisture could get into the valve
core and cause air leakage. If the caps
have been lost, have new ones put on
as soon as possible.
Tread wear indicator
CHECKING YOUR TIRES
Check the tires tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have builtin
tread wear indicators to help you know
when the tires need replacement. When
the tread depth wears to 1.6 mm (0.06
in.) or less, the indicators will appear. If
you can see the indicators in two or more
adjacent grooves, the tire should be re-
placed. The lower the tread, the higher
the risk of skidding.
The effectiveness of snow tires is lost
if the tread wears down below 4 mm
(0.16 in.). Check the tires regularly for damage
such as cuts, splits and cracks. If any
damage is found, consult with a techni-
cian and have the tire repaired or re-
placed.
Even if the damage does not appear seri-
ous, a qualified technician should examine
the damage. Objects which have pene-
trated the tire may have caused internal
damage.
Any tires which are over 6 years old
must be checked by a qualified techni-
cian even if damage is not obvious.
Tires deteriorate with age even if they
have never or seldom been used.
This applies also to the spare tire and
tires stored for future use.
REPLACING YOUR TIRES
When replacing a tire, use only the
same size and construction as original-
ly installed and with the same or great-
er load capacity.
Using any other size or type of tire may
seriously affect handling, ride, speedome-
ter/odometer calibration, ground clearance,
and clearance between the body and tires
or snow chains.
