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. 541)
If the replaced fuse blows again, have the vehicle inspected by your
●
Toyota dealer.
If there is an overload in a 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.
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 Toyota 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.
●
NOTICE
Before replacing fuses
