CAUTION
When programming the HomeLink\b
Universal Transceiver, you may be
operating a garage door or other
device. Make sure people and ob-
jects are out of the way of the ga-
rage door or other device to pre-
vent potential harm or damage.
Do not use this HomeLink\b Univer-
sal Transceiver with any garage
door opener that lacks the safety
stop and reverse feature as re-
quired by federal safety standards.
(This includes any garage door
opener model manufactured before
April 1, 1982.) A garage door open-
er which cannot detect an object
(signaling the door to stop and re-
verse), does not meet current feder-
al safety standards. Using a garage
door opener without these features
increases risk of serious injury or
death.
This device complies with part 15 of the
FCC Rules and with RSS −210 of the
Industry Canada. Operation is subject to
the following two conditions: (1) This
device may not cause harmful interfer-
ence, and (2) this device must accept
any interference that may be received,
including interference that may cause
undesired operation.
WARNING: This transmitter has been
tested and complies with FCC and
Industry Canada DOC/MPAC rules.
Changes or modifications not ex-
pressly approved by the party respon-
sible for compliance could void the
user ’s authority to operate the device.

CAUTION
Do not overestimate the antilock
brake system: Although the antilock
brake system assists in providing ve-
hicle control, it is still important to
drive with all due care and maintain
a moderate speed and safe distance
from the vehicle in front of you, be-
cause there are limits to the vehicle
stability and effectiveness of steering
wheel operation even with the anti
lock brake system on.
If tire grip performance exceeds its
capability, or if hydroplaning occurs
during high speed driving in the rain,
the antilock brake system does not
provide vehicle control.
Antilock brake system is not de-
signed to shorten the stopping dis-
tance: Always drive at a moderate
speed and maintain a safe distance
from the vehicle in front of you.
Compared with vehicles without an
antilock brake system, your vehicle
may require a longer stopping dis-
tance in the following cases:
Driving on rough, gravel or snow
covered roads.
Driving with tire chains installed.
Driving over the steps such as the
joints on the road.
Driving on roads where the road
surface is pitted or has other differ-
ences in surface height.
Install all 4 tires of specified size at
appropriate pressure: The antilock
brake system detects vehicle speeds
using the speed sensors for respec-
tive wheels’ turning speeds. The use
of tires other than specified may fail
to detect the accurate turning speed,
resulting in a longer stopping dis-
tance.

220 Temperature A, B, C—T he tem per a-
ture grades are A (the highest), B,
and C, representing the tire’s resis-
tance to the generation of heat and
its ability to dissipate heat when
tested under controlled conditions on
a specified indoor laboratory test
wheel. Sustained high temperature
can cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B
and A represent higher levels of per-
formance on the laboratory test wheel
than the minimum required by law.
Warning: The temperature grades for
this tire are established for a tire that
is properly inflated and not over-
loaded. Excessive speed, underinfla-
tion, or excessive loading, either sep-
arately or in combination, can cause
heat buildup and possible tire failure.

The compact spare tire saves space
in your luggage compartment, and its
lighter weight helps to improve fuel
economy and permits easier installa-
tion in case of a flat tire.
The compact spare tire can be used
many times, if necessary. It has tread
life of up to 4800 km (3000 miles) de-
pending on road conditions and your
driving habits. When tread wear indi-
cators appear on the tire, replace the
tire.
See also the tire information on page
291 for details on the tread wear indi-
cators and other service information.
CAUTION

The compact spare tire was de-
signed especially for your To-
yota. Do not use it on any other
vehicle.
 Do not use more than one com-
pact spare tire at the same
time.
 Do not exceed 80 km/h (50
mph) when driving with the
compact spare tire.
 Replace the compact spare tire
with the standard tire as soon
as possible.
 Avoid sudden a cceleration,
sudden d eceleration and sharp
turns with the compact spare
tire.
NOTICE
Your ground clearance is re-
duced when the compact spare
tire is installed so avoid driving
over obstacles and drive slowly
on rough, unpaved roads and
speed bumps. Also, do not at-
tempt to go through an auto-
matic car wash as the vehicle
may get caught, resulting in
damage.

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.
Pay particular attention to the vehicle’s
underside and wheel housings 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. 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” 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.

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.
Plastic wheel ornaments: The plastic
wheel ornaments are damaged easily by
organic substances. If any organic sub-
stances splashes an ornament, be sure to
wash it off with water and check if the
ornament is damaged.
CAUTION
Do not attach the heavily damaged
plastic wheel ornament. It may fly off
the wheel and cause accidents while
the vehicle is moving.
Aluminum wheels: Use only a mild soap
or neutral detergent.
Plastic bumpers: Wash carefully. Do not
scrub with abrasive cleaners. The bumper
faces are soft.
Road tar: Remove with turpentine or
cleaners that are marked safe for painted
surfaces.
NOTICE
Do not use organic substances (gaso-
line kerosene, benzine or strong sol-
vents) which may be toxic or cause
damage.
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. 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 to remove it before driving
your Toyota through an automatic car
wash.

Leather interior
The leather upholstery may be cleaned
with neutral detergent for wool.
Remove dirt using a soft cloth dampened
with 5% solution of neutral detergent for
wool. Then thoroughly wipe off all traces
of detergent with a clean damp cloth.
After cleaning or whenever any part of the
leather gets wet, dry with a soft clean
cloth. Allow the leather to dry in a venti-
lated shaded area.
NOTICE
If a stain should fail to come out
with a neutral detergent, apply a
cleaner that does not contain an
organic solvent.
 Never use organic substances such
as benzine, alcohol or gasoline, or
alkaline or acid solutions for clean-
ing the leather as these could
cause discoloring.
 Use of a nylon brush or synthetic
fiber cloth, etc. may scratch the
fine grained surface of the leather.
Mildew may develop on soiled leath-
er upholstery. Be especially careful
to avoid oil spots. Try to keep your
upholstery always clean.
 Long exposure to direct sunlight
may cause the leather surface to
harden and shrink. Keep your ve-
hicle in a shaded area, especially in
the summer.
 The interior of your vehicle is apt
to heat up on hot summer days, so
avoid placing on the upholstery
items made of vinyl or plastic or
containing wax as these tend to
stick to leather when warm.
 Improper cleaning of the leather up-
holstery could result in discolor-
ation or staining.
If you have any questions about the
cleaning of your Toyota, your local
Toyota dealer will be pleased to answer
them.

Maintenance requirements
Your Toyota vehicle has been designed for
fewer maintenance requirements with long-
er service intervals to save both your time
and money. However, each regular mainte-
nance, as well as day−to −day care, is
more important than ever before to ensure
smooth, trouble− free, safe, and economical
driving.
It is the owner ’s responsibility to make
sure the specified maintenance, including
general maintenance service, is performed.
Note that both the new vehicle and
emission control system warranties specify
that proper maintenance and care must be
performed. See “Owner ’s Warranty
Information Booklet” or “Owner ’s Manual
Supplement” for complete warranty
information.
General maintenance
General maintenance items are those day −
to −day care practices that are important to
your vehicle for proper operation. It is the
owner ’s responsib ility to ensure that the
general maintenance items are performed
regularly.
These checks or inspections can be done
either by yourself or a qualified technician,
or if you prefer, your Toyota dealer will be
pleased to do them at a nominal cost. Scheduled maintenance
The scheduled maintenance items listed in
the “Scheduled Maintenance Guide” or
“Owner ’s Manual Supplement” are those
required to be serviced at regular inter-
vals.
For details of your maintenance schedule,
read the “Scheduled Maintenance Guide”
or “Owner ’s Manual Supplement”.
It is recommended that only genuine
Toyota parts be used for maintenance
or for the repair of the emission con-
trol system.
The owner may elect to use nonToyota
supplied parts for replacement pur-
poses without invalidating the emission
control system warranty. However, use
of replacement parts which are not of
equivalent quality may impair the effec-
tiveness of the emission control sys-
tems.
You may also elect to have mainte-
nance, replacement, or repair of the
emission control devices and system
performed by any automotive repair es-
tablishment or individual without invali-
dating this warranty. See “Owner’s War-
ranty Information Booklet” or “Owner’s
Manual Supplement” for complete war-
ranty information.Where to go for service?
Toyota technicians are well
−trained spe-
cialists and are kept up to date with the
latest service information through technical
bulletins, service tips, and in −dealership
training programs. They learn to work on
Toyotas before they work on your vehicle,
rather than while they are working on it.
You can be confident that your Toyota
dealer ’s service department performs the
best job to meet the maintenance require-
ments on your vehicle–reliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. If any prob-
lems should arise with your vehicle while
under warranty, your Toyota dealer will
promptly take care of it. Again, be sure
to keep a copy of the repair order for any
service performed on your Toyota.
What about doityourself maintenance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented in Section 8.
