After a fuse is replaced

●

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 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.

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 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.
