NOTICE
■Cleaning detergents
Do not use organic substances such as benzene or gasoline, acidic or alkaline solu-
tions, dye, bleach or other detergent. Doing so may discolor the vehicle interior or
cause streaks or damage to painted surfaces.
■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.

■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. 3 6 5 )
●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.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing to do so may cause damage, and possibly a fire or injury.
●Never use a fuse of a higher amperage rating than indicated, or use any other
object in place of a fuse.
●Always use a genuine Lexus fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
This can cause extensive damage or even fire.
●Do not modify fuses or the fuse box.

■When the battery is removed or discharged
The power windows, power back door and moon roof must be initialized.
(→ P. 4 6 2 )
CAUTION
■Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flammable
gas that may be emitted from the battery.
●Make sure the jumper cable is connected to the correct terminal and that it is not
unintentionally in contact with any part other than the intended terminal.
●Do not allow the jumper cables to come into contact with the “+” and “-” termi-
nals.
●Do not allow open flame or use matches, cigarette lighters or smoke near the
