■After a fuse is replaced
●When installing the lid, make sure that the tab is installed securely.
●If the lights do not turn on even after the fuse has been replaced, a bulb
may need replacement. ( P.357)
●If the replaced fuse blows again, have
the vehicle inspected by any autho- rized Toyota retailer or Toyota autho-rized repairer, or any reliable repairer.
■If there is an overload in a circuit
The fuses are designed to blow, protect- ing the wiring harness from damage.
■When replacing light bulbs
Toyota recommends that you use genu-
ine Toyota products designed for this vehicle.
Because certain bulbs are connected to circuits designed to prevent overload, non-genuine parts of parts not designed
for this vehicle may be unusable.
WARNING
■To prevent system breakdowns and vehicle fire
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.
