■

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 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.

●

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.

LED light bulbs

The side turn signal lights and high mounted stoplight consist of a number of
LEDs. If any of the LEDs burn out, take your vehicle to your Scion dealer to
have the light replaced.

■

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 have built up on the inside of the lens.

●

Water has built up inside the headlight.

CAUTION

■

Replacing light bulbs

●

Turn off the lights. Do not attempt to replace the bulb immediately after
turning off the lights.
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.

●

Do not attempt to repair or disassemble light bulbs, connectors, electric
circuits or component parts.
Doing so may result in death or serious injury due to electric shock.

■

To prevent damage or fire

Make sure bulbs are fully seated and locked.
