When you insert a cassette tape, the exposed tape should
face to the right.
The player will automatically start when you insert a cassette
tape. At this time, ºPLAYº appears on the display.
If a metal or chrome equivalent cassette tape is put in the
cassette player, the player will automatically adapt to it and
ºMTLº appears on the display.
To stop or eject the cassette tape, push the ºEJECTº button.
Auto±reverse feature: After the cassette player reaches the

Vehicle skid control system failure warning
SV31035
These lights warn that there is a problem somewhere in the
vehicle skid control system or traction control system.
The lights will come on when the ignition key is turned to ºONº,
and will go off after a few seconds.
If the ºVSCº warning light and ºTRAC OFFº indicator/warning
light come on, the vehicle skid control system and traction
control system do not work. However, as conventional braking
operates when applied, there is no problem to continue your
driving.
If any of the following conditions occurs, this indicates a
malfunction somewhere in the parts monitored by the warning
light system. Contact your Lexus dealer as soon as possible
to service the vehicle:
 The ºVSCº warning light or ºTRAC OFFº indicator/warning
light do not come on after the ignition is turned to on.
 The ºVSCº warning light and ºTRAC OFFº indicator/warning
light remain on after the ignition is turned to on. 
The ºVSCº warning light and ºTRAC OFFº indicator/warning
light come on while driving without pushing ºTRAC OFFº
switch.
CAUTION
Do not rely excessively on the vehicle skid control
system. Even if the vehicle skid control system is
operating, you must always drive carefully and atten-
tively to avoid serious injury. Reckless driving will
result in an unexpected accident. If the slip indicator
light flashes, sounding an alarm, special care should
be taken while driving.
 Only use tires of specified size. The size, manufac-
turer, brand and tread pattern for all 4 tires should be
the same. If you use the tires other than specified, or
different type or size, the vehicle skid control system
may not function correctly. When replacing the tires
or wheels, contact your Lexus dealer.

TYPES OF TIRES
Determine what kind of tires your vehicle is originally equipped
with.
1. Summer tires
Summer tires are high±speed capability tires best suited to
highway driving under dry conditions.
Since summer tires do not have the same traction performance
as snow tires, summer tires are inadequate for driving on
snow±covered or icy roads. For driving on snow±covered or
icy roads, we recommend using snow tires. If installing snow
tires, be sure to replace all four tires.
2. All season tires
All season tires are designed to provide better traction in snow
and to be adequate for driving in most winter conditions, as well
as for use all year round.
All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow.
Also, all season tires fall short in acceleration and handling
performance compared with summer tires in highway driving.
CAUTION
 Do not mix summer and all season tires on your
vehicle as this can cause dangerous handling
characteristics, resulting in loss of control.
 Do not use tires other than the manufacturer's
designated tires, and never mix tires or wheels of the
sizes different from the originals.

STARTING AND DRIVING
252
LIMITED±SLIP DIFFERENTIAL
Some vehicles are equipped with a limited±slip differential. If
one rear wheel begins 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 Lexus 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 result in serious injury.
NOTICE
Use only a spare tire of the same size, construction and
load capacity as the original tires on your Lexusbecause damage to the limited±slip differential couldpossibly occur with another tire type.

IN CASE OF AN EMERGENCY
271
SV41034
When closing the board, replace the hook also in its
original position as shown.
NOTICE
If you close the back door with the board hooked, thehook may be damaged.
Spare tire with turning direction indicators
(Some models)
SV41014
The spare tire with turning direction indicators is of a
uni±directional type and is intended for use on the
passenger side of the vehicle.
Installing the wheel on the driver side of the vehicle will not
affect tire performance. If the spare tire is used on the driver
side of the vehicle, it should be used only temporarily and then
replaced with the correct one.

Uniform tire quality grading
This information has been prepared in accordance with
regulations issued by the National Highway T raffic Safety
Administration of the U.S. Department of Transportation.
It provides the purchasers and/or prospective purchasers
of Lexus vehicles with information on uniform tire quality
grading.
Your Lexus dealer will help answer any questions you may
have as you read this information.
DOT quality grades ± All passenger vehicle tires must
conform to Federal Safety Requirements in addition to
these grades. Quality grades can be found where
applicable on the tire sidewall between tread shoulder and
maximum section width. For example: Treadwear 200
Traction AA Temperature A
Treadwear ± The treadwear grade is a comparative rating
based on the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and a half (1 ± 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual
conditions of their use, however, and may depart significantly
from the norm due to variations in driving habits, service
practices and differences in road characteristics and climate.
Traction AA, A, B, C ± The traction grades, from highest to
lowest, are AA, A, B and C, and they represent the tire's ability
to stop on wet pavement as measured under controlled
conditions on specified government test surfaces of asphalt
and concrete. A tire marked C may have poor traction
performance. Warning: The traction grade assigned to this tire is based on
braking (straight ahead) traction tests and does not include
cornering (turning) traction.
Temperature A, B, C ± The temperature grades are A (the
highest), B, and C, representing the tire's resistance 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 corresponds 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 performance 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 overloaded.
Excessive speed, underinflation, or excessive loading, either
separately or in combination, can cause heat buildup and
possible tire failure.
Tire selection
When replacing a tire, use only the same size and
construction as originally installed and with the same or
greater load capacity.
Using any other size or type of tire may seriously affect
handling, ride, speedometer/odometer calibration, ground
clearance, and clearance between the body and tires or snow
chains.
