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.
