In the following cases, contact your Toyo-
ta dealer as soon as possible:

The SRS airbags have been inflated.

The front part of the vehicle (shaded in
the illustration) was involved in an ac-
cident not of the extent to cause the
SRS airbags to inflate

The pad section of the steering wheel or
front passenger airbag cover (shaded in
the illustration) is scratched, cracked, or
otherwise damaged. Toyota strongly urges the use of child
restraint systems for children small
enough to use them.
The laws of all fifty states in the U.S.A.
and Canada now require the use of a child
restraint system.
Your vehicle conforms to SAEJ1819.
If a child is too large for a child restraint
system,
the child should sit in the rear seat
and must be restrained using the vehicle's
seat belt. See Seat beltsº for details.CAUTION!

For effective protection in automo-
bile accidents and sudden stops,
children must be properly re-
strained using a seat belt or child
restraint system depending on the
age and size of the child. Holding
a child in your arms is not a substi-
tute for a child restraint system. In
an accident, the child can be
crushed against the windshield, or
between you and the vehicle's in-
terior.

Toyota strongly urges use of a
proper child restraint system
which conforms to the size of the
child and is put on the rear seat.
According to accident statistics,
the child is safer when properly re-
strained in the rear seat than in the
front seat.

Never install a r ear-facing child re-
straint system on the front seat. In
the event of an accident, the force
of the rapid inflation of the airbag
can cause severe injury if a rear-
facing child restraint system is put
on the front seat.

Unless it is unavoidable, do not
put a forward-facing child re-
straint system on the front seat.

If you must install a forward-fac-
ing child restraint system on the
front seat, move the seat as far
back as possible.

Make sure that you have complied
with all installation instructions
provided by the child restraint
manufacturer and that the system
is properly secured.

CAUTION!

Do not mix summer and all season
tires on your vehicle as this can
cause dangerous handling charac-
teristics, resulting in loss of con-
trol.

Do not use tires other than the
manufacturer 's designated tires,
and never mix tires or wheels of the
sizes different from the originals.

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
bodyshop 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 trans-
ported 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.
CAUTION
When cleaning under floor or chas-
sis, be careful not to injure your
hands.!
1. Rinse off loose dirt with a hose. Re- move any mud or road salt from the
underside of the vehicle or in 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.
Aluminum wheels: Use only a mild soap or
neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub with ab rasive cleaners. The bumper
faces are soft.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.

Keep your tire pressures at the proper
level.
The recommended cold tire pressures,
tire size and the vehicle capacity weight
are also given in Part 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 wheel 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
pos-
sibility of tire damage from road hazards.
If a tire frequently needs refilling, have it
checked by your Toyota dealer.
The following instructions for check-
ing tire pressure should be observed:

The pressure should be checked
only when the tires are cold. If your
vehicle 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 pressure that
are even just a few pounds off can de-
grade handling and ride.

Do not bleed or reduce tire pres-
sure 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.

CHECKING YOUR TIRES
Check the tire tread for the tread wear
indicators. If the indicators show, re-
place the tires.
The tires on your Toyota have built-in
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 adja-
cent grooves, the tire should be replaced.
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 tech-
nician and have the tire repaired or re-
placed.
Even if the damage does not appear seri-
ous, a qualified technician should ex-
amine the damage. Objects which have
penetrated the tire may have caused in-
ternal damage.
Any tires which are over six 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
also applies 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 origi-
nally installed and with the same or
greater load capacity.
Using any other size or type of tire may se-
riously affect handling, ride, speedomeet-
er/odometer calibration, ground clear-
ance, and clearance between the body
and tires or snow chains.
CAUTION

Do not mix radial, bias belted, or
bias-ply tires on your vehicle. It
can cause dangerous handling
characteristics, r esulting in loss of
control.

Do not use tire or wheels other
than the manufacturer's recom-
mended size.!
Toyota recommends all four tires, or at
least both of the front or rear tires be
replaced at a time as a set.
See If you have a flat tireº in Part 4 for tire
change procedure.
When a tire is replaced, the wheel
should always be balanced.
An unbalanced wheel may affect vehicle
handling and tire life. Wheels can get out
of balance with regular use and should
therefore be balanced occasionally.
When replacing a tubeless tire, the air
valve should also be replaced with a
new one.

To equalize tire wear and help extend
tire life, Toyota recommends that you
rotate your tires every 12000 km (7500
miles). However, the most appropriate
timing for tire rotation may vary ac-
cording to your driving habits and
road surface conditions.
See If you have a flat tireº in Part 4 for tire
change procedure.
When rotating tires, check for even wear
and damage. Abnormal wear is usually
caused by incorrect tire pressure, improp-
er wheel alignment, out-of-balance
wheels, or severe braking. WHEN TO USE SNOW TIRES OR
CHAINS
Snow tires or chains are recom-
mended when driving on snow or ice.
On wet or dry roads, conventional tires
provide better traction than snow tires.
SNOW TIRE SELECTION
If you need snow tires, select tires of
the same size, construction and load
capacity as the original tires on your
Toyota.
Do not use tires other than those men-
tioned above.
Do not install studded tires
without first checking local regulations for
possible restrictions.
SNOW TIRE INSTALLATION
Snow tires should be installed on all
wheels.
Installing snow tires on the front wheels
only can lead to an excessive difference
in road grip capability between the front
and rear tires which would cause loss of
vehicle control.
When storing removed tires, you should
store them in a cool dry place.
Mark the direction of rotation and be sure
to install them in the same direction when
replacing.
CAUTION

Do not drive with the snow tires
incorrectly inflated.

Never drive over 120 km/h (75
mph) with any type of snow tires.!
TIRE CHAIN SELECTION
Use the tire chains of correct size and
type.
Use SAE Class Sº type radial tire chains
except radial cable chains or V-bar type
chains.
Regulations regarding the use of tire
chains vary according to location or
type of r oad, so always check them be-
fore installing chains.
CHAIN INSTALLATION
Install the chains on the front tires as
tightly as possible. Do not use tire
chains on the rear tires. Retighten
chains after driving 0.5 '1.0 km
(1/4 '1/2 mile).
When installing chains on your tires, care-
fully follow the instructions of the chain
manufacturer.

192If wheel covers are used, they will be
scratched by the chain band, so remove
the covers before putting on the chains.


Do not exceed 50 km/h (30 mph) or
the chain manufacturer's recom-
mended speed limit, whichever is
lower.

Drive carefully avoiding bumps,
holes, and sharp turns, which may
cause the vehicle to bounce.

Avoid sharp turns or locked-wheel
braking, as use of chains may ad-
versely affect vehicle handling.
CAUTION!
WHEN TO REPLACE YOUR WHEELS
If you have wheel damage such as
bending, cracks or heavy corrosion,
the wheel should be replaced.
If you fail to replace damaged wheels, the
tire may slip off the wheel or they may
cause loss of handling control.
WHEEL SELECTION
When replacing wheels, care should
be taken to ensure that the wheels are
replaced by ones with the same load
capacity, diameter, rim width, and off-
set.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may ad-
versely affect handling, wheel and bear-
ing life, brake cooling, speedometer/
odometer calibration, stopping ability,
headlight aim, bumper height, vehicle
ground clearance, and tire or snow chain
clearance to the body and chassis. Replacement
with used wheels is not rec-
ommended as they may have been sub-
jected to rough treatment or high mileage
and could fail without warning. Also, bent
wheels which have been straightened
may have structural damage and there-
fore should not be used. Never use an in-
ner tube in a leaking wheel which is de-
signed for a tubeless tire.
