Maintenance and care
CAUTION
The engine compartment contains many mechanisms and fluids that may move sud-
denly, become hot, or become electrically energized. To avoid death or serious injury,
observe the following precaution:
When working on the engine compartment
Keep hands, clothing, and tools away from the moving fans and engine drive belt.
Be careful not to touch the engine, radiator, exhaust manifold, etc. right after driv-
ing as they may be hot. Oil and other fluids may also be hot.
Do not leave anything that may burn easily, such as paper or rags, in the engine
compartment.
Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel
and battery fumes are flammable.
Be extremely cautious when working on the battery. It contains poisonous and
corrosive sulfuric acid.

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. 603)
If the replaced fuse blows again, have the vehicle inspected by your Lexus
dealer.
If there is an overload in the circuit
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.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer.
