Maintenance and care
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. 266)
If the replaced fuse blows again, have the vehicle inspected by your
Scion 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, 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 Scion fuse or equivalent.
Never replace a fuse with a wire, even as a temporary fix.
This can cause extensive damage or even fire.
Do not modify the fuse or the fuse box.
NOTICE
Before replacing fuses
Have the cause of electrical overload determined and repaired by your Scion
dealer, as soon as possible.
