• After driving in an area contaminated with soot, oily smoke, mine
dust, iron powder or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoline are spilled on the paint surface
If the paint is chipped or scratched, have it repaired immediately.
To prevent the wheels from corroding, remove any dirt and store in a
place with low humidity when storing the wheels.
Cleaning the exterior lights
Wash carefully. Do not use organic substances or scrub with a hard brush.
This may damage the surfaces of the lights.
Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses.
To prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side
wiper arm upward first, and repeat for the passenger side. When returning
the wipers to their original position, do so from the passenger side first.
When using an automatic car wash
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper
blades may be damaged.

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. 407)
If the replaced fuse blows again, have the vehicle inspected by any
authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
