3106-1. Maintenance and care
WARNING
QPrecaution regarding the rear
bumper with Blind Spot Monitor
If the paint of the rear bumper is chipped
or scratched, the system may malfunc-
tion. If this occurs, consult your Lexus
dealer.
NOTICE
QTo prevent paint deterioration and
corrosion on the body and compo-
nents (aluminum wheels etc.)
OWash the vehicle immediately in the
following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar, pollen or tree sap is present on the paint surface
• If dead insects, insect droppings or bird droppings are present on the
paint surface
• After driving in an area contaminated with soot, oily smoke, mine dust, iron
powder or chemical substances
• If the vehicle becomes heavily soiled with dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
OIf the paint is chipped or scratched,
have it repaired immediately.
OTo prevent the wheels from corroding,
remove any dirt and store in a place
with low humidity when storing the
wheels.
QCleaning the exterior lights
OWash carefully. Do not use organic
substances or scrub with a hard brush.
This may damage the surfaces of the
lights.
ODo not apply wax to the surfaces of the
lights.
Wax may cause damage to the lenses.
QWhen using an automatic car wash
(vehicles with rain-s ensing windshield
wipers)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wip-
ers may operate and the wiper blades
may be damaged.
QWhen using a high pressure car wash
OWhen washing the vehicle, do not
spray the camera or its surrounding
area directly with a high pressure
washer. Shock applied from high pres-
sure water may cause the device to not
operate normally.
ODo not spray water directly on the
radar which is equipped behind the
emblem. Otherwise it may cause the
device to be damaged.
ODo not bring the nozzle tip close to
boots (rubber or resin manufactured
cover), connectors or the following
parts. The parts may be damaged if
they come into contact with high-pres-
sure water.
• Traction related parts
•Steering parts
• Suspension parts
• Brake parts
OKeep the cleaning nozzle at least 11.9
in. (30 cm) away from the vehicle
body. Otherwise resin section, such as
moldings and bumpers, may be
deformed and damaged. Also, do not
continuously hold the nozzle in the
same place.
ODo not spray the lower part of the
windshield continuously.
If water enters the air conditioning sys-
tem intake located near the lower part
of the windshield, the air conditioning
system may not operate correctly.
ODo not wash the underside of the vehi-
cle using a high pressure car washer.

4168-1. Specifications
QTraction 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 con-
trolled conditions on specified govern-
ment 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.
QTemperature 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 condi-
tions 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 perfor-
mance 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 exces-
sive loading, either separately or in combi-
nation, can cause heat buildup and
possible tire failure.
