Type B
*: Replace the fuse with one of the same ampere rating as the original
■ Under the instrument panel
■After a fuse is repl
●If the lights do not turn on even after the fuse has been replaced, a bulb may need replacement.
●If the replaced fuse blows again, have the vehicle inspected by your Toyota dealer.
■If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION
■To prevent system breakdowns and vehicle fire
Observe the following precautions.
Failing 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 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 fuse or the fuse box.
NOTICE
■Before replacing fuses
Have the cause of electrical overload determined and repaired by your Toyota dealer as soon as possible.
