The API Service Symbol is located anywhere on the outside
of the container.
The top portion of the label shows the oil quality by API
(American Petroleum Institute) designation such as SL.
The center portion of the label shows the SAE viscosity
grade such as SAE 5W −30. “Energy− Conserving”, shown

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.

BODY
4143. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
Windshield washer nozzles:
Make sure that the nozzles do
not become blocked when waxing. If a nozzle becomes
blocked, contact your Lexus dealer to have the vehicle
serviced.
NOTICE
If a nozzle becomes blocked, do not try to clear it with
a pin or other object. The nozzle will be damaged.
CLEANING THE INTERIOR
CAUTION
Be careful not to splash water or spill liquid on the
floor. This may prevent the side airbags from
activating correctly, resulting in serious injury.
Do not wash the vehicle floor with water, or allow
water to get onto the floor when cleaning the vehicle
interior or exterior. Water may get into audio system
components or other electrical components above or
under the floor carpet (or mat) and cause a
malfunction; and it may cause body corrosion.
Leather trimmed Interior
The selected leather is used in your Lexus. Due to
characteristics of leather products, some parts of leather may
be rough, uneven or scratched originally.
To keep good appearance, we recommend you to clean it
periodically twice a year.
