WARNING
■Discharge headlights (if equipped)
●Contact your Toyota dealer before replacing the discharge headlights
(including light bulbs).

nectors, power supply circuits, or related components.

■ 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.
