WARNING

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. Failure 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 the bulb, socket, electrical wiring,
or sub components. This may cause serious injury due to electric shock.

Vehicles with discharge headlights:
While the low beam headlights are
turned on, and for a short time after they
have been turned off, metal compo-
nents at the rear of the headlight
assembly will be extremely hot. To pre-
vent burns, do not touch these metal
components until you are certain they
have cooled down.

WARNING

Discharge headlights (if equipped)

Contact your Toyota dealer before replacing the discharge headlights
(including light bulbs).

Do not touch the discharge headlight’s high voltage socket when the head-
lights are turned on.
An extremely high voltage of 30000 V will be discharged and could result
in serious injury or death by electric shock.

Do not attempt to take apart or repair the low beam headlight bulbs, con-
nectors, power supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.

When replacing the rear turn signal lights or stop/tail lights
Inspect the gasket for any damage (rip, tear, hole, etc.). If there is any dam-
age, please contact your Toyota dealer and have the gasket replaced.
Improper installation of the gasket may result in water entering the rear light
unit.

To prevent damage or fire

Make sure bulbs are fully seated and locked.

Check the wattage of the bulb before installing to prevent heat damage.

NOTICE

When installing the back door trim
To prevent damage, be careful not to pinch any of the wire harnesses or
