3. After adjusting, be sure to tighten the cross rails by
turning knobs clockwise.
CAUTION
Make sure the cross rails are fixed securely by pushing
forward and rearward them. Failure to do so may cause
an unexpected accident or severe injury in the event of
emergency braking or a collision.
Follow the manufacturer’s instructions and precautions when
installing the attachments or their equivalent.
CAUTION
When you load cargo on the roof luggage carrier,
observe the following:
 Place the cargo so that its weight is distributed
evenly between the front and rear axles.
 If loading long or wide cargo, never exceed the
vehicle overall length or width. (See “Specifications”
on page 564 for information on your vehicle overall
length and width.)
 Before driving, make sure the cargo is securely
fastened on the roof luggage carrier.
 Loading cargo on the roof luggage carrier will make
the center of the vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns, sudden braking
or abrupt maneuvers, otherwise it may result in loss
of control or vehicle rollover due to failure to operate
this vehicle correctly.
 If driving for a long distance, on rough roads, or at
high speeds, stop the vehicle now and then during
the trip to make sure the cargo remains in its place.
 Do not exceed 58 kg (130 lb.) cargo weight on the roof
luggage carrier.
NOTICE
When loading the luggages, be careful not to scratch
the surface of the moon roof.

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 car 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 ATreadwear
— 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.

Tire chain selection
 1 Side chain2 Cross chain
Use the tire chains of correct size.
For P265/65R17 tires, use the following type chains. mm (in.)
A: Diameter of side chain 5.0 (0.20)
B: Width of side chain 18.0 (0.71)
C: Length of side chain 46.0 (1.81)
D: Width of cross chain 22.6 (0.89)
E: Length of cross chain 38.1 (1.5)
F: Diameter of cross chain 6.3 (0.25)Regulations regarding the use of tire chains vary
according to location or type of road. Always check local
regulations before installing chains.
NOTICE
If the wrong combination of tire and chain is used, the
chains could damage the vehicle body.

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 a damaged wheel, the tire may slip off the
wheel or 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.
CAUTION
Observe the following instructions. Otherwise, an
accident may occur resulting in death or serious
injuries.
 Do not use wheels other than the manufacturer’s
recommended size, as this may cause dangerous
handling characteristics resulting in loss of control.
 Do not use wheels of different brands, sizes and
types, as this may cause dangerous handling
characteristics resulting in loss of control.
