HEADLAMP AIMING



<USING A BEAM SETTING EQUIPMENT>



1.The headlamps should be aimed with the proper beam setting equipment, and in accordance with the equipment manufacture’s instructions.
2.Alternately turn the adjusting screw to adjust the headlamp aiming.

<USING A SCREEN>



PRE-AIMING INSTRACTION


1.Inspect for badly rusted or faulty headlamp assemblies.
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.Put the headlamp levelling switch in "0" position.
7.Thoroughly clean the headlamp lenses.


8.Place the vehicle on a level floor, perpendicular to a flat screen 3 m away from the bulb centre-marks on the headlamp lens.
9.Rock vehicle sideways to allow vehicle to assume its normal position.
10.Bounce the front suspension through three oscillations by applying the body weight to hood or bumper.
11.Run the engine at a speed of 2,000 r/min to charge the battery.
12.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 centre-marks on the headlamp lens to the floor. Transfer the measurement to the screen. Horizontal tape or mark on the screen is for reference of vertical adjustment.
note Height from the floor to the centre of the headlamps (Reference value): 892 mm <Single cab> or 887 mm <Club cab and Double cab>
(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.

HEADLAMP ADJUSTMENT


caution
  • Do not cover a headlamp for more than three minutes to prevent the plastic headlamp lens deformation.
  • When adjusting one headlamp beam, make sure that another headlamp is off by disconnecting the connector from it. When reconnecting the connector, make sure that the headlamp beam is not disturbed accidentally.
  • Be sure to adjust the aiming adjustment screw in the tightening direction.



  1. The low-beam headlamp should project on the screen upper edge of the beam (cut-off).
  2. If not the case, turn the adjusting screws to achieve the specified low-beam cut-off location on the aiming screen.

Standard value:
Vertical direction; 36 mm (0.69°) below horizontal (H)
Horizontal direction; 15° sloping section intersects the vertical line (V)
Limit:
Vertical direction; Not within 21 mm (0.4°) below horizontal (H)
Horizontal direction; ± 26 mm (± 0.5°) from the vertical line (V)
note The illustration shows LH drive vehicles. For RH drive vehicles, it is symmetrical.
