Pregnant wom
an. Lexus recommends the use of a seat belt. Ask your doctor
for specific recommendations. The lap belt should be worn securely and as
low as possible over the hips and not on the waist.
Injured person. Lexus recommends the use of a seat belt. Depending on the
injury, first check with your doctor for specific recommendations.
CAUTION
Persons should ride in their seats properly wearing their seat
belts whenever the vehicle is moving. Otherwise, they are
much more likely to suffer serious bodily injury in the event
of sudden braking or a collision.
When using the seat belts, observe the following:
 Use the belt for only one person at a time. Do not use a
single belt for two or more people ± even children.
 Avoid reclining the seatbacks too much. The seat belts
provide maximum protection when the seatbacks are in the
upright position. (See ºAdjusting seatback angleº.)
 Be careful not to damage the belt webbing or hardware.
Take care that they do not get caught or pinched in the seat
or doors.
 Inspect the belt system periodically. Check for cuts,
fraying, and loose parts. Damaged parts should be
replaced. Do not disassemble or modify the system.
Keep the belts clean and dry. If they need cleaning, use a mild soap
solution or lukewarm water. Never use bleach, dye, or abrasive
cleaners ± they may severely weaken the belts.
 Replace the belt assembly (including bolts) if it has been used in a
severe impact. The entire assembly should be replaced even if
damage is not obvious.
Fastening front and rear seat belts
16E014±1
Adjust the seat as needed and sit up straight and well back in the seat. To
fasten your belt, pull it out of the retractor and insert the tab into the
buckle.
You will hear a click when the tab locks into the buckle.
The seat belt length automatically adjusts to your size and the seat pos\
ition.

BRAKE PAD WEAR LIMIT INDICATORS
31E016
The brake pad wear limit indicators on your disc brakes give a warning
noise when the brake pads are worn to the extent that replacement is
required.
If you hear a squealing or scraping noise while driving, have the brake \
pads
checked and replaced by your Lexus dealer as soon as possible. Expensive
rotor damage can result if the pads are not replaced when needed.
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.

CHECKING TIRE PRESSURE
63E004±1
The recommended cold tire pressures, tire size and the vehicle capacity
weight are given on the label.
You should check the tire pressures every two weeks, or at least once a mon\
th.
And don't forget the spare! The air pressure for the spare tire should be 220
kPa (2.2 kgf/cm
2 or bar, 32 psi). 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
economy,
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 deformation and/or tire
separation. So keep your tire pressures at the proper level. If a tire needs
frequent refilling, have it checked by your Lexus dealer.
High tire pressure produces a harsh ride, handling problems, excessive wear
at the center of the tire tread, and a greater possibility of tire damage \
from road
hazards.
The following instructions for checking 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 the tire can be
misleading. Besides, tire pressures that are even just a few pounds off can
degrade handling and ride.
 Do not bleed or reduce tire pressure after driving. It is normal for the
tire pressure to be higher after driving.
 Never exceed the vehicle capacity weight. The passengers and luggage
weight should be located so that the vehicle is balanced.
 Be sure to reinstall the tire valve caps. Without the valve caps, dirt or
moisture could get into the valve core and cause air leakage. If the ca\
ps
have been lost, have new ones put on as soon as possible.

CHASSIS209
If you have tire damage such as cuts, splits, cracks deep enough to expose
the fabric, or bulges indicating internal damage, the tire should be
replaced.
If a tire often goes flat or cannot be properly repaired due to the size o\
r location
of a cut or other damage, it should be replaced. If you are not sure, c\
onsult
with your Lexus dealer.
If an air loss occurs while driving, do not continue driving with a deflat\
ed tire.
Driving even a short distance can damage a tire beyond repair.
Any tires which are over 6 years old must be checked by a qualified
technician 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.
Uniform tire quality grading
This information has been prepared in accordance with regulations
issued by the National Highway Traffic 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. These quality grades
are molded on the sidewall.
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 g\
raded 100.
The relative performance of tires depends upon the actual conditions of the\
ir
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 A, B, C ± The traction grades, from highest to lowest, are 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 (straigh\
t
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 performan\
ce
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 grade of this tire 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.
Do not mix radial, belted, or conventional tires on your vehicle.
Do not use tires or wheels other than the manufacturer's recommended
size.
It can cause dangerous handling characteristics, resulting in loss of co\
ntrol.
If you need to change from conventional tires to radial tires or vice ve\
rsa,
replace them as a set.
INSTALLING SNOW TIRES AND CHAINS
When to use snow tires or chains
Snow tires or chains are recommended when driving on snow or ice.
On wet or dry roads, conventional or radial tires provide better traction \
than
snow or studded tires.
Snow tire selection
If you need snow tires, select the same size, construction and load capacity
as the original tires on your Lexus.
Do not use tires other than stated above. Since your vehicle has radial t\
ires
as original equipment, make sure your snow tires also have radial
construction. 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 could
cause loss of vehicle control.

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, a tire may slip off a wheel or they may
cause loss of handling control.
Replacement with used wheels is not recommended as they may have been
subjected to rough treatment or high mileage and could fail without warning.
Also, bent wheels which have been straightened may have hidden structural
damage and therefore should not be used. Never use an inner tube in a leaking
wheel which is designed for a tubeless tire.
Wheel selection
When replacing wheels, care should be taken to ensure that they are
equivalent to those removed in load capacity, diameter, rim width, and
offset.
Correct replacement wheels are available at your Lexus dealer.
A wheel of a different size or type may adversely affect handling, wheel and
bearing 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.
ALUMINUM WHEEL PRECAUTIONS
 After driving your vehicle the first 1600 km (1000 miles), check that the
wheel nuts are tight.
 If you have rotated, repaired, or changed your tires, check that the whe\
el
nuts are still tight after driving 1600 km (1000 miles).
 When using tire chains, be careful not to damage the aluminum wheels.
 Use only the Lexus wheel nuts and wrench designed for your aluminum
wheels.
 When balancing your wheels, use only Lexus balance weights or
equivalent and a plastic or rubber hammer.
 As with any wheel, periodically check your aluminum wheels for damage.
If damaged, replace immediately.
SUSPENSION AND CHASSIS
CAUTION
Do not modify the suspension/chassis with lift kits, spacers,
springs, etc. It can cause dangerous handling characteristics,
resulting in loss of control.
