■Adjusting the headlight aim
Low beam (vertical adjustment)
Using a Phillips-head screw-
driver, turn adjustment bolt A so
that the bubble is within the 2
center lines.
Remember the turning direction
and the number of turns.
Turn bolt B the same number of
turns and in the same direction
as step 1.
Low beam (horizontal adjustment)
Turn adjustment bolt A so that the red line on the gauge is in the middle
of the “0” mark (within the blue lines to either side of the gauge).
High beam (vertical and horizontal adjustment)
Turn each adjustment bolt in either direction so that the bubble in
within the 2 center lines (vertical), and the red line on the gauge is in
the middle of the “0” mark (within the blue lines to either side of the
gauge) (horizontal).
If you feel that there is a large deviation, have the headlight aim
adjusted at a Lexus dealer.

■High-intensity discharge (HID) headlights
If voltage to the high-intensity discharge bulbs is insufficient, the light may not come
on, or may go out temporarily. The high-intensity discharge bulbs will come on
when normal power is restored.
CAUTION
■Replacing light bulbs
●Turn off the headlights. Do not attempt to replace the bulb immediately after turn-
ing 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.
●Do not attempt to take apart or repair the low beam discharge headlight bulbs,
connectors, power supply circuits, or related components.
Doing so could result in electric shock and death or serious injury.
■High-intensity discharge (HID) headlights
●Contact your Lexus dealer before replacing high-intensity discharge headlights
(including light bulbs).
●Do not touch the high-intensity discharge headlight’s high voltage socket when
the headlights are turned on.
An extremely high voltage of 20000 V will be discharged and could result in
death or serious injury by electric shock.
■To prevent damage or fire
Make sure bulbs are fully seated and locked.
