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. 453)  
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.  
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 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  
Toyota dealer as soon as possible.
