4-3. Do-it-yourself maintenance
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 the fuse or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional, as soon as possible.
