Maintenance and care

■LED light bulbs
The lights other than the headlight low/high beams (vehicles with discharge head-
lights), high beams or high beam/near-infrared ray transmitters (vehicles with dis-
charge headlights), and rear fog lights (if equipped) each consist of a number of
LEDs. If any of the LEDs burn out, take your vehicle to your Lexus dealer to have the
light replaced.
■Condensation build-up on the inside of the lens
Temporary condensation build-up on the inside of the headlight lens does not indi-
cate a malfunction. Contact your Lexus de aler for more information in the following
situations:
●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 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.
