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.

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.
Do not modify the fuse or the fuse box.
NOTICE
Before replacing fuses

Maintenance and care
Lights other than the above
If any of the lights listed below has burned out, have it replaced by
your Scion dealer.
Side turn signal lights
High mounted stoplight
When replacing the left side headlight
Be sure to install the fuse cover properly.
Condensation build-up on the inside of the lens
Temporary condensation build-up on the inside of the headlight lens does
not indicate a malfunction.
Contact your Scion dealer for more information in the following situations:
Large drops of water are built up on the inside of the lens.
Water has built up inside the headlight.
LED high mounted stoplight
The high mounted stoplight consists of a number of LEDs. If any of the LEDs
burn out, take your vehicle to your Scion dealer to have the light replaced.
CAUTION
Replacing light bulbs
Turn off the headlights. Do not attempt to replace the bulb immediately
after turning off the headlights.
The bulbs become very hot and may cause burns.
Do not touch the glass portion of the light bulb with bare hands. When it is
unavoidable to hold the glass portion, use and hold with a clean dry cloth
to avoid getting moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
Fully install light bulbs and any parts used to secure them. Failing to do so
may result in heat damage, fire, or water entering the headlight unit. This
may damage the headlights or cause condensation to build up on the lens.
To prevent damage or fire
Make sure bulbs are fully seated and locked.
