- make sure there is no damage or deformation of the body in the area of the headlights;
- fill the fuel tank;
- make sure the oil level is correct;
- make sure the coolant level is correct;
- bring the tire pressure up to the norm;
- place the spare wheel, tool and jack in their proper places;
- remove cargo from the trunk;
- place a person of average weight (75 kg) in the driver's seat.
Preparing to adjust headlights (using the screen)
Fig. 1.56. Vehicle installation diagram in preparation for headlight adjustment
1. Prepare the vehicle as follows:
- place the vehicle in a room where it is dark enough to clearly see the boundary of the light spots of the headlights. The boundary of the light spots of the headlights is a distinct line, below which the light spots from the headlights are visible, and above which they are absent (Fig. 1.56);
- position the vehicle at a 90° angle to the wall;
- the distance from the vehicle to the wall must be 25 m (from the center of the headlight bulb);
- place the vehicle on a level surface;
- rock the vehicle up and down to settle the suspension.
Attention! Distance 25 m between vehicles (from the center of the headlight bulb) and the wall is necessary for proper adjustment of the direction of the headlight beams. If this is not possible, ensure a distance of exactly 3 m for checking and adjustment. (The light spot area of the headlights changes with the distance, so it is necessary to follow the instructions in Figure 1.56)
2. Prepare a sheet of thick white paper (approximately 2m (height) x 4m (width)) to use as a screen.
3. Draw a vertical line (V line) in the center of the screen.
Fig. 1.57. Screen installation diagram
4. Install the screen as shown in Figure 1.57.
Fig. 1.58. Screen baseline diagram
5. Draw baselines on the screen (line H, V Left, V Right), as shown in Figure 1.58.
The baselines for "low beam check" and "high beam check" are different.
Mark the centers of the headlight bulbs on the screen. If the position of the bulb centers cannot be determined by the marks on the headlight, use the centers of the headlight bulbs or the manufacturer's name on the headlight as a guide.
1. Line H (headlight height): Draw a horizontal line across the screen so that it passes through the applied marks of the lamp centers. Line H should be at the same height as the marks of the low beam lamp centers.
2. Line V Left, V Right (left (LH) and right (RH) lamp center marks): Draw two vertical lines so that they intersect line H at the points where the low beam lamp center marks are applied.
Checking headlight adjustment
1. Cover the headlight or disconnect the corresponding electrical connector to prevent the light from the headlight that is not being checked from influencing the headlight whose adjustment is being checked.
Warning! Do not keep the headlight closed for more than 3 minutes. The headlight lens is made of synthetic polymer and can easily melt or be damaged by heat.
When checking the high beam lamps, cover the low beam lamp or disconnect the corresponding connector.
2. Start the engine. The engine crankshaft speed should be at least 1500 min⁻¹.
3. Set the headlight range control switch to position 0 (zero).
Fig. 1.59. Headlight light spot adjustment diagram
4. Turn on the headlights and make sure that the border of the headlight light spots falls within the area shown in Figure 1.59.
The adjustment data is given below.
Distance to screen – 25 m.
the border of the light spots of the headlights is from 48 to 696 mm below the H line for low beam.
The original can be viewed on the website: ToyotaMan
Distance to the screen – 3 m.
the border of the light spots of the headlights from 6 mm to 84 mm below the H line for low beam.
Distance to screen – 25 m.
the border of the light spots of the headlights is 249 mm below the H line for low beam.
Distance to the screen – 3 m.
The border of the light spots of the headlights is 30 mm below the H line for low beam.
Since the low beam and high beam are combined in the headlight, if the low beam is adjusted correctly, the high beam should be adjusted correctly. However, check both headlights to make sure they are adjusted correctly.
Headlight adjustment
1. Adjust the light beam in the vertical direction:
Fig. 1.60. Headlight adjustment screws
Adjust the headlight beam by turning the adjusting screw A with a screwdriver (Fig. 1.60);
Caution! The final turn of the adjusting screw must be made in a clockwise direction. If the screw is overtightened, loosen it and then retighten it so that the final turn of the screw is made in a clockwise direction.
- adjust the low beam;
- the headlight beam moves up when the adjusting screw is turned clockwise and moves down when the screw is turned counterclockwise.
2. Adjust the light beam in the horizontal direction: adjust the light beam of the headlight by turning the adjusting screw B with a screwdriver (Fig. 1.60).
