Limited- slip differential
Some Toyotas are equipped with a lim-
ited- slip differential. If one rear wheel be-
gins to spin, the limited- slip differential is
designed to aid traction by automatically
transmitting driving force to the other rear
wheel. If you are not sure whether your
vehicle is equipped with one, you can ask
your Toyota dealer.
CAUTION
Do not start or run the engine while
your vehicle is supported by a jack.
The vehicle could be driven off the
jack and could pose a danger or re-
sult in serious injury.
NOTICE
Use only a spare tire of the same
size, construction and load capacityas the original tires on your Toyotabecause damage to the limited- slip
differential could possibly occur withanother tire type.
Your Toyota's identification
The vehicle identification number (VIN)
is the legal identifier for your vehicle.
This number is on the left top of the
instrument panel, and can be seen
through the windshield from outside.
The vehicle identification number (VIN) is
also on the Certification Label.
This is the primary identification number
for your Toyota. It is used in registering
the ownership of your vehicle.

SUPRA (U)131
Compact spare tire
The compact spare tire is designed for
temporary emergency use only.
The compact spare tire is identified by the
distinctive wheel design and color and
special wording ºTEMPORARY USE ONLYº
molded into the side wall of the tire.
The standard tire should be repaired and
replaced as soon as possible.
To keep the compact spare tire noticeable,
do not hide the wheel by a wheel cover
or such. The compact spare tire saves space in
your luggage compartment, and its lighter
weight helps to improve fuel economy and
permits easier installation 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) depending on
road conditions and your driving habits.
When tread wear indicators appear on the
tire, replace the tire.
See also the tire section in Chapter 7- 2
for details on the tread wear indicators
and other service information.
CAUTION

The compact spare tire was de-
signed especially for your Toyota.
Do not use it on any other vehicle.
Do not exceed 80 km/h (50 mph)
when driving with the compact
spare tire.
Avoid sudden acceleration, sudden
deceleration and sharp turns with
the compact spare tire.
NOTICE
Your ground clearance is reduced
when the compact spare tire isinstalled so avoid driving over ob- stacles and drive slowly on rough,
unpaved roads and speed bumps.Also, do not attempt to go through anautomatic car wash as the vehicle
may get caught, resulting in damage.

ÐRequired tools and spare tire
1. Get the wheel nut wrench, jack, jack
handle and spare tire.
To prepare yourself for an emergency, you
should fam iliarize yourself with the use of
the jack, each of the tools and their stor-
age locations.To remove the jack, loosen the bolt and
remove it.
When storing the jack, secure it by follow-
ing removal step in reverse order to pre-
vent it from flying forward during a colli-
sion or sudden braking.To remove the spare tire:
1. Remove the spare tire cover.
2. Loosen the bolt and remove it.
When storing the spare tire, put it in place
with the outer side of the wheel facing up.
Then secure the tire by repeating the
above removal steps in reverse order to
prevent it from flying forward during a
collision or s udden braking.

SUPRA (U)135
ÐChanging wheels
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 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 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. ÐReinstalling wheel nuts8. Reinstall all the wheel nuts finger
tight.
Reinstall the wheel nuts and tighten them
as much as you can by hand. Press back
on the tire back and see if you can tight-
en them more.

SUPRA (U)137
ÐAfter changing wheels
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 the
torque specified in Part 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.
If 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
commercial tow truck service, tow your
vehicle carefully in accordance with the
instructions given in ºÐEmergency
towingº in this chapter.
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 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.
If your vehicle needs to be
towedÐ

SUPRA (U)167
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 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.
CAUTION

Do not mix radial, bias belted, or
bias- ply tires on your vehicle. It
can cause dangerous handling char-
acteristics, resulting in loss of con-
trol.
Do not use tires 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 ºIf 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.
Rotating tires
70030F08
Do not perform rotation of the tires,
from front to rear or from left to right,
or using the compact spare tire. Per-
forming such tire rotation may result in
the tires interfering with the body or in
uneven wear of the tires, so that steer-
ability of the vehicle is impaired.
Tires with turning direction indicatorÐ
The tire is a uni- directional type and can-
not be used for tire rotation. Using the tire
on the opposite side to the designated
side will impair the tire performance.
The compact spare tireÐ
The tire is designed for temporary use
only and cannot be used for tire rotation.

SUPRA (U)169
NOTICE
Do not attempt to use a tire chain onthe compact spare tire, as it may re-sult in damage to the vehicle as wellas the tire.
Replacing wheels
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 re-
placed by ones with the same load ca-
pacity, diameter, rim width, and offset.
This must be observed on compact spare
tires, too.
Correct replacement wheels are available
at your Toyota dealer.
A wheel of a different size or type may
adversely affect handling, wheel and bear-
ing life, brake cooling, speedometer/odom-
eter calibration, stopping ab ility, headlight
aim, bumper height, vehicle ground clear-
ance, 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 therefore
should not be used. Never use an inner
tube in a leaking wheel which is designed
for a tubeless tire.
