7. Remove the wheel nuts andchange 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 the top bolt started through
its hole. Wiggle the 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−met-
al contact at the mounting surface can
cause wheel nuts to loosen and
eventually cause a wheel to come off
while driving.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 completelyand tighten the wheel nuts.
Turn the jack handle counterclock-
wise 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 engaged 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
by torque wrench at 103 N·m
(10.5 kgf·m, 76 ft·lbf), as soon
as possible after changing
wheels. Otherwise, the nuts
may loosen and the wheels
may fall off, which could cause
a serious accident.
 Do not attach a heavily dam-
aged plastic wheel ornament.
It may fly off the wheel and
cause accidents while the ve-
hicle is moving.

ment with the valve stem as shown. 2. Press hand firmly on one side of wheel ornament and then firmly
tap the other side around the edge
of wheel ornament with the heel
of your hand to snap into place.
CAUTION
Take due care in handling the or-
nament to avoid unexpected per-
sonal injury.
11. Check the air pressure of the re- placed tire.
Adjust the air pressu re to the specifi-
cation designed on page 292 in Sec-
tion 8. If the pre ssure 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.
As soon after changing wheels as
possible, tighten the wheel nuts to the
torque specified on page 292 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 124 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.
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 120 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.
NOTICE
If you rock your vehicle, observe the
following precautions to prevent dam-
age to the transmission and other
parts.
Do not depress the accelerator ped-
al while shifting the selector lever
or before the transmission is com-
pletely shifted to forward or reverse
gear.
 Do not race the engine and avoid
spinning the wheels.

(a) Towing with wheel lift type truck——From front
—From rear
(b) Using flat bed truckIf 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” on page 236 in this Section.
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 pre-
cautions 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. (a) Towing with wheel lift type truck
From front—
Release the parking brake.
NOTICE
When lifting wheels, take care to en-
sure adequate ground clearance for
towing at the opposite end of the
raised vehicle. Otherwise, the bumper
and/or underbody of the towed vehicle
will be damaged during towing.
From rear—
Manual transmission:
We recommend using a towing dolly
under the front wheels. If you do not
use a towing dolly, place the ignition
key in the “ACC” position and put the
transmission in neutral.
NOTICE
Do not tow with the key removed or
in the “LOCK” position when towing
from the rear without a towing dolly.
The steering lock mechanism is not
strong enough to hold the front
wheels straight.

2008 COROLLA from Aug. ’07 Prod. (OM12B28U)
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 eyelet and towing cable or
chain. The eyelet 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 eyelet 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.
If you cannot shift the selector lever
out of “P” position to other positions
even though the brake pedal is de-
pressed, use the shift lock override but-
ton as follows:
1. Turn the ignition key to “LOCK” position. Make sure the parking
brake is applied.
2. Pry up the cover with a flathead screwdriver or equivalent.

Toyota, through the diligent research, de-
sign and use of the most advanced
technology available, helps prevent corro-
sion and provides you with the finest qual-
ity vehicle construction. Now, it is up to
you. Proper care of your Toyota can help
ensure long −term corrosion prevention.
The most common causes of corrosion
to your vehicle are:
The accumulation of road salt, dirt and
moisture in hard −to −reach areas under
the vehicle.
Chipping of paint, or undercoating
caused by minor accidents or by
stones and gravel.
Care is especially important if you live
in particular areas or operate your ve-
hicle under certain environmental condi-
tions:
Road salt or dust control chemicals will
accelerate corrosion, as will the pres-
ence of salt in the air near the sea −
coast or in areas of industrial pollution.
High humidity accelerates corrosion es-
pecially when temperatures range just
above the freezing point.
Wetness or dampness to certain parts
of your vehicle for an extended period
of time, may cause corrosion even
though other parts of the vehicle may
be dry.
High ambient temperatures can cause
corrosion to those components of the
vehicle which do not dry quickly due to
lack of proper ventilation.
The above signifies the necessity to keep
your vehicle, particularly the underside, as
clean as possible and to repair any dam-
age to paint or protective coatings as
soon as possible.
To help prevent corrosion on your
Toyota, follow these guidelines:
Wash your vehicle frequently. It is, of
course, necessary to keep your vehicle
clean by regular washing, but to prevent
corrosion, the following points should be
observed:
If you drive on salted roads in the
winter or if you live near the ocean,
you should hose off the undercarriage
at least once a month to minimize cor-
rosion.
High pressure water or steam is effec-
tive for cleaning the vehicle’s underside
and wheel housings. Pay particular
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 removing. The
lower edge of doors, rocker panels and
frame members have drain holes which
should not be allowed to clog with dirt
as trapped water in these areas can
cause corrosion.
Wash the underside of the vehicle thor-
oughly when winter is over.
See “Washing and waxing your Toyota” on
page 241 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.
Protecting your Toyota from
corrosion

’08 Corolla_U (L/O 0706)
241
2008 COROLLA from Aug. ’07 Prod. (OM12B28U)
Check the interior of your vehicle. Wa-
ter and dirt can accumulate under the
floor mats and could cause corrosion. Oc-
casionally check under the mats to make
sure the area is dry. Be particularly care-
ful when transporting chemicals, cleans-
ers, 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 recommend
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 installing
the shields if they are recommended for
your area.
Keep your vehicle in a well ventilated
garage or a roofed place. Do not park
your vehicle in a damp, poorly venti-
lated garage. If you wash your vehicle in
the garage, or if you drive it covered with
water or snow, your garage may be so
damp as to cause corrosion. Even if your
garage is heated, a wet vehicle can cor-
rode if the ventilation is poor. Washing your Toyota
Keep your vehicle clean by regular
washing.
The following cases may cause weakness
to the paint or corrosion to the body and
parts. Wash your vehicle as soon as pos-
sible.
When driving in a coastal area
When driving on a road sprinkled with
antifreeze
When exposed to coal tar, tree sap,
bird droppings and carcass of an insect
When driving in areas where there is
a lot of smoke, soot, dust, iron dust or
chemical substances
When the vehicle becomes remarkably
dirty with dust and mud
Handwashing your Toyota
Work in the shade and wait until the
vehicle body is not warm to the touch.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your
hands.
Exhaust gases cause the exhaust
pipe to become quite hot. When
washing the vehicle, be careful not
to touch the pipe until it has cooled
sufficiently, as touching a hot ex-
haust pipe can cause burns.
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or the wheel
wells.
2. Wash with a mild car −wash soap,
mixed according to the manufacturer ’s
instructions. Use a soft cotton mitt and
keep it wet by dipping it frequently into
the wash water. Do not rub hard—let
the soap and water remove the dirt.
Fuel filler door: Do not apply water (high −
pressure car wash, for example) at or
near the fuel tank inlet with the fuel filler
door opened. If the water enters the air
vent, you may experience trouble with re-
fueling or rough engine idling.
Plastic wheel ornaments: The plastic
wheel ornaments are damaged easily by
organic substances. If any organic sub-
stances splash an ornament, be sure to
wash them off with water and check if the
ornament is damaged.

Aluminum wheels: Use only a mild soap
or neutral detergent.
NOTICE
Do not use corrosive chemical
based cleaners on your wheels.
(Example: hydrofluoric acid)
 Do not use steam cleaners or the
chemicals therein to clean your
wheels.
 Do not use scouring pads, wire
brushes, or coarse abrasives to
clean your wheels.
 Do not use alcohol, solvents, gaso-
line, or other nonneutral deter-
gents, because they may alter the
wheel’s appearance and resistance
to corrosion.
Plastic bumpers: Wash carefully. Do not
scrub with abrasive cleaners. The bumper
faces are soft. Exterior lights: Wash carefully. Do not use
organic substances or scrub them with a
hard brush. This may damage the sur-
faces of the lights.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
3. Rinse thoroughly—dried 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 hard—you might scratch
the paint.
NOTICE
Do not use organic substances
(gasoline, kerosene, benzine or
strong solvents), which may be tox-
ic or cause damage.
 Do not scrub any part of the ve-
hicle with a hard brush, which may
cause damage.
Automatic car wash
Your vehicle may be washed in an auto-
matic car wash, but remember that the
paint can be scratched by some types of
brushes, unfiltered washing water, or the
washing process itself. Scratching reduces
paint durability and gloss, especially on
darker colors. The manager of the car
wash should be able to advise you wheth-
er the process is safe for the paint on
your vehicle.
NOTICE
To prevent damage to the antenna,
make sure it is removed before driv-
ing your Toyota through an automatic
car wash.
Waxing your Toyota
Polishing and waxing is recommended
to maintain the original beauty of your
Toyota’s finish.
Apply wax once a month or if the vehicle
surface does not repel water well.
1. Always wash and dry the vehicle be- fore you begin waxing, even if you are
using a combined cleaner and wax.
