2. These conditions must be corrected before a satisfactory adjustment can be made.
3. Inspect tyre inflation, and adjust if it is necessary.
4. If the fuel tank is not filled up, put weight in the luggage compartment to make up for the fuel shortage so that the weight will become 90% of full-state weight or heavier. (0.8 kg per litter)
5. There should be no other load in the vehicle other than driver or substituted weight of approximately 75 kg placed in driver's position.
6. Turn the headlamp levelling switch to the switch position "0." <Vehicles with headlamp manual levelling system>

8. Thoroughly clean the headlamp lenses.
Place the vehicle on a level floor, perpendicular to a flat screen 3 m away from the bulb or LED centre position of the low-beam.
|caution||Check that the square shaped marking (LED headlamp) or round shaped marking (halogen headlamp) is on the lens surface.|
10. Rock vehicle sideways to allow vehicle to assume its normal position.
11. To correct for distortion of the suspension, rock the bumpers on the front/rear side of the vehicle up and down three times alternately.

13. Four lines of adhesive tape (or equivalent markings) are required on screen or wall:
(1) Position a vertical tape or mark so that it is aligned with the vehicle centre line.
(2) Measure the distance from the bulb centre position to the floor. Transfer the measurement to the screen. Horizontal tape or mark on the screen is for reference of vertical adjustment.
(3) Measure the distance from the centre line of the vehicle to the centre of each headlamp. Transfer the measurement to the screen. Vertical tape or mark on the screen with reference to the centre line of each headlamp bulb.
