■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. 517)
● If the replaced fuse blows again, have the vehicle inspected by your Toyota
dealer.
■ If there is an overload in the circuit
The fuses are designed to blow, protecting the wiring harness from damage.
■ When replacing light bulbs
Toyota recommends that you use genuine Toyota products designed for this
vehicle. Because certain bulbs are connected to circuits designed to prevent
overload, non-genuine parts or parts not designed for this vehicle may be
unusable.
WARNING
■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 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 Toy-
ota dealer as soon as possible.
