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
connectors with the back door trim.

WARNING
■If the engine has to be turned off while driving
●Power assist for the brakes and steering wheel will be lost, making the
brake pedal harder to depress and the steering wheel heavier to turn.
Decelerate as much as possible before turning off the engine.
● Vehicles without a smart key system: Never attempt to remove the key, as
doing so will lock the steering wheel.

etrain and related parts may be dam-
aged.
