■After a fuse is replaced
■If there is an overload in a 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.
■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 replace a fuse with a wire, even as a temporary fix.
