■

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. 284)

●

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 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 Scion fuse or equivalent. 

●

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.
