● Contact your Toyota dealer before replacing discharge headlights (includ-
ing light bulbs).

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 serious injury or death.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
