■LED high mounted stoplight
The high mounted stoplight consists of a number of LEDs. If any of
the LEDs burn out, take your vehicl e to your Toyota dealer to have
the light replaced.
■ Condensation build-up on th e inside of the lens
Contact your Toyota dealer for more information in the following situations.
Temporary condensation build-up on the inside of the headlight lens does
not indicate a malfunction.
● 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 headlights. Do not attempt to replace the bulb immediately
after turning off the headlights.
The bulbs become very hot and may cause burns.
● Do not touch the glass portion of the light bulb with bare hands. Hold the
bulb by the plastic or metal portion.
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.
■ To prevent damage or fire
Make sure bulbs are fully seated and locked.
