Maintenance and care
NOTICE
■Cleaning detergents
●Do not use organic substances such as benzene or gasoline, acidic or alkaline
solutions, dye, bleach or other detergent. Doing so may discolor the vehicle inte-
rior or cause streaks or damage to painted surfaces.
●Do not use polish wax or polish cleaner. The instrument panel's or other interior
part’s painted surface may be damaged.
■Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of leather
surfaces.
●Remove any dust or dirt on leather surfaces immediately.
●Do not expose the vehicle to direct sunlight for extended periods of time. Park
the vehicle in the shade, especially during summer.
●Do not place items made of vinyl, plastic, or that contain wax on the upholstery, as
they may stick to the leather surface if the vehicle interior heats up significantly.
■Water on the floor
Do not wash the vehicle floor with water.
Vehicle systems such as the audio system may be damaged if water comes into
contact with electrical components under the floor of the vehicle, and may also
cause the body to rust.
■Cleaning the inside of the rear window
●Be careful not to scratch or damage the heater wires or antenna.
●Do not use glass cleaner to clean the rear window, as this may cause damage to
the rear window defogger heater wires or antenna. Use a cloth dampened with
lukewarm water to gently wipe the window clean. Wipe the window in strokes
running parallel to the heater wires or antenna.

■After a fuse is replaced
●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (P. 4 5 2 )
●If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
■If there is an overload in the circuits
The fuses are designed to blow before the entire wiring harness is damaged.

Vehicle 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 fail-
ure.
The 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 for this tire are 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.
