- Park the vehicle so that the headlights are 10 m (32.8 ft) away from the wall.
NOTE:
Make sure that the vehicle is parked perpendicular to the wall.
NOTE:
EU vehicles require a 1% downward inclination (-1%) in the headlight beam. As such, a vehicle parked 10 m from the wall would have a 10 cm beam drop.
- Make sure that all 4 tires are inflated to their recommended pressures. Refer to Tire Pressures
.
- Make sure that the ride height is set to standard.
- Use a laser measure to make sure the vehicle is positioned perpendicular to the wall. Measure the distance from the center of both front wheels to the wall. Both measurements from the center of the wheels to the wall should be equal. If the measurements are unequal, reposition the vehicle.
- Use a laser measure to determine the center point of the vehicle. Hold the laser measure perpendicular to the wall and project the laser onto the center point of the vehicle. Mark the center line on the wall.
- Measure 805 mm (31.7 in) (distance Y) horizontally on either side of the center line, and then mark these measurements with a piece of tape.
NOTE:
Measure Distance Y Left and Right from the Center Line

- Put weight on the driver's seat equal to 75 kg.
- Clean the headlights with an IPA wipe and allow to dry.
- Turn on the low beam headlights.
- Use a shop towel to completely cover the RH headlight.
- Check whether the top of the LH beam aligns with the horizontal tape mark on the wall, and that the angled portion aligns with the LH vertical tape mark on the wall. If not, remove the LH underhood apron, Assembly - Underhood Apron - Front (Remove And Replace)
, locate the headlight adjusters and adjust the headlight.
NOTE:
For LHD vehicles, the left half the beam is flat, and the right half of the beam angles upward. For RHD vehicles, the right half of the beam is flat, and the left half of the beam angles upward. This procedure shows headlight adjustment for a LHD vehicle.
