CAUTION
■Using the tire jack
Improper use of the tire jack may cause the vehicle to suddenly fall off the jack, leading
to death or serious injury.
●Do not use the tire jack for any purpose other than replacing tires or installing and
removing tire chains.
●Only use the tire jack that comes with this vehicle for replacing a flat tire.
Do not use it on other vehicles, and do not use other tire jacks for replacing tires on
this vehicle.
●Always check that the tire jack is securely set to the jack point.
●Do not put any part of your body under the vehicle while it is supported by the jack.
●Do not start or run the engine while your vehicle is supported by the jack.
●Do not raise the vehicle while someone is inside.
●When raising the vehicle, do not put an object on or under the jack.
●Do not raise the vehicle to a height greater than that required to replace the tire.
●Use a jack stand if it is necessary to get under the vehicle.
●Be sure to turn off the height control and stop the engine.
Take particular care when lowering the vehicle to ensure that no one working on or
near the vehicle will be injured.
■Using the jack handle
Tighten all the jack handle bolts securely us ing a Phillips-head screwdriver, to prevent
the extension parts from coming apart unexpectedly.

When trouble arises
7-2. Steps to take in an emergency
If the vehicle becomes stuck
Stop the engine. Set the parking brake and shift the shift lever to P.
Remove the mud, snow or sand from around the stuck tire.
Place wood, stones or some other material under the tires to help provide
traction.
Restart the engine.
Lock the center differential. (→P. 3 4 3 )
Shift the shift lever to the D or R positi on and release the parking brake. Then,
while exercising caution, depress the accelerator pedal.
■When it is difficult to free the vehicle
Turn off TRAC or Active TRAC/VSC/Trailer Sway Control if these functions are ham-
pering your attempts to free the vehicle. ( →P. 3 5 3 )
Carry out the following procedures if the tires spin or the vehicle becomes
stuck in mud, dirt, or snow:
Press to turn off TRAC or Active TRAC/VSC/

Tire information
Ti r e s i z e
(→ P. 585)
DOT and Tire Identification Number (TIN) (→ P. 5 8 4 )
Location of treadwear indicators (→ P. 4 76 )
Tire ply composition and materials
Plies are layers of rubber-coated parallel cords. Cords are the strands which form the
plies in a tire.
Radial tires or bias-ply tires
A radial tire has “RADIAL” on the sidewall. A tire not marked “RADIAL” is a bias-ply
tire.
TUBELESS or TUBE TYPE
A tubeless tire does not have a tube and air is directly put into the tire. A tube type tire
has a tube inside the tire and the tube maintains the air pressure.
Load limit at maximum cold tire inflation pressure (→ P. 589)
Maximum cold tire inflation pressure (→ P. 589)
This means the pressure to which a tire may be inflated.
Uniform tire quality grading
For details, see “Uniform Tire Quality Grading” that follows.
Summer tires or all season tires (→ P. 4 7 9 )
An all season tire has “M+S” on the sidewall. A tire not marked “M+S” is a summer
tire.

Vehicle specifications
This information has been prepared in accordance with regulations issued by the
National Highway Traffic Safety Administration of the U.S. Department of Trans-
portation.
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 infor-
mation.
■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.
Performance may differ 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 rep-
resent 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.

GX 460 _O M_ OM6 0F 6 8U _(U )8-1. Specifications
■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.
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 of a tire
assume that it is properly inflated and
not overloaded.
Excessive speed, underinflation, or excessive loading, either separately or in com-
bination, can cause heat buildup and possible tire failure.
