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 indi-
cated, 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.
