Maintenance and care
■ To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failure to do so may cause damage, and possibly a fire or injury.
● Never use a fuse of a higher amperage rating than that 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 fuses or fuse boxes.
■ Before replacing fuses
Have the cause of electrical overload determined and repaired by your Lexus
dealer as soon as possible.
