VENZA_OM_OM73030U_(U) ■ 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. 537)
● If the replaced fuse blows again, have the vehicle inspected by your
Toyota dealer.
■ If there is an overload in the circuits
The fuses are designed to blow, protecting the wiring harness from damage.
CAUTION■ 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 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 fuses or the fuse box.
NOTICE■ Before replacing fuses
Have the cause of electrical overload determined and repaired by your
Toyota dealer.
