●If the lights do not turn on even after the fuse has been replaced, a bulb may
need replacement. (P. 445)
●If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.

Observe the following precautions.
Failure to do so may cause damage to the vehicle, 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.
●Do not modify the fuses or fuse boxes.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your
