During each maintenance, it is necessary to check the proper operation of the headlight corrector, lighting devices and light signaling devices.
Every 45,000 km of vehicle mileage, as well as after the first 2,000 km, adjust the direction of the headlight beams.
Headlight adjustment
The direction of the light beams of the headlights should be such that the road in front of the car is well lit, and oncoming drivers are not blinded when the low beam headlights are turned on. The headlights are adjusted by turning screws 1 and 2 (figure 125), which rotate the optical element in the vertical and horizontal planes. The headlights can be adjusted using a screen, which can be a smooth wall of a house, a sheet of plywood measuring 2X1 m, etc.
Place the fully fueled and equipped car, with a load of 75 kg on the driver's seat, on a flat horizontal surface 5 m from the screen so that the longitudinal axis of the car is perpendicular to the screen. Before marking the screen, make sure that the air pressure in the tires is normal, and then rock the car from the side so that the suspension springs take the normal position.
Draw on screen (figure 126) vertical lines: the axial O and lines A and B passing through point E, corresponding to the centers of the headlights. These lines must be symmetrical relative to the axial line of the car. At a height equal to the distance of the centers of the headlights from the floor, draw line 1 and below it 65 mm line 2 of the centers of the light spots.
Set the headlight range control knob on the instrument panel to the position that corresponds to the load when there is only one driver in the car.
Turn on the low beam. Sequentially, first for the right headlight (the left one is covered with thick material), and then for the left (the right one is closed) adjust with screws 1 and 2 (see figure 125) beams of light from the headlights. When the headlights are adjusted, the upper boundary of the light spots should coincide with line 2 (see figure 126), and the points of intersection of the horizontal and inclined sections of the light spots are with points E.
Replacing lamps
To replace the headlamp bulb, turn the headlamp housing counterclockwise until it stops and remove it. Then remove the wiring harness from the bulb, press the spring clips of the bulb mount and remove the bulb. When replacing the bulb, wear gloves to avoid leaving greasy fingerprints on the glass. If there are such fingerprints on the bulb, remove them with alcohol. This is necessary because the headlamps use halogen bulbs, whose bulb heats up to high temperatures, and greasy fingerprints will cause the bulb to darken and the bulb to quickly fail.
To replace the parking light bulb in the headlight, remove the socket with the bulb from the optical element, gently press on the bulb, turn it counterclockwise and remove it from the socket.
To replace the front turn signal bulb, remove the socket from the bulb holder, turn the bulb holder assembly counterclockwise and remove it from the socket.
When replacing a burnt-out bulb on the side turn signals, remove the socket from the socket.
In the lampshade, to replace the lamp, you need to carefully press on the sides of the diffuser in its middle part and remove the diffuser from the lampshade body. After that, replace the lamp.
The rear lights have their lamps replaced from the luggage compartment side. To do this, remove the protective covers, press the lamp base fastening clamps and remove the base together with the lamps. Then replace the burnt-out lamps on the removed base.
