■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. 695) 
● If the replaced fuse blows again, have the vehicle inspected by any autho- 
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer. 
■ 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.
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 any 
authorized Toyota retailer or Toyota authorized repairer, or any reliable 
repairer as soon as possible.
