1. This system is installed on most models. It controls the activation of the brake lights, parking lights, low beams and tail lights, and also controls the outside temperature, opening of the tailgate/trunk lid, brake pad wear, and the fluid level in the cooling system and washer reservoirs. On some models, this system includes a low engine oil level indicator, which is installed on the instrument panel and works together with the oil pressure indicator.
2. The system unit together with the display are installed in a single module.
Maintenance interval indicator
3. The system contains an indicator that lights up when the vehicle has completed the mileage (or time) specified in the maintenance schedule.
4. On models produced before 1996, to reset the display and turn off the indicator, you need to press the switch located inside the glove compartment and hold it for at least four seconds with the ignition on. On models produced since 1997, the switch is located on the instrument panel under the symbol with an arrow. You need to press it with a thin rod and hold it for at least four seconds with the ignition on. If the car is under warranty, then this operation should be performed by dealers.
Replacement of components
5. The following are the procedures for removing components. Disconnect the negative battery cable before performing the procedure. Installation is the reverse order of removal.
Display
6. Remove the instrument panel trim (paragraph 10).
7. Remove the screws, disconnect the electrical connectors and remove the unit.
Display indicator light
8. Remove the display (see above).
9. Pull out the cover and remove the corresponding bulb and socket.

10. Remove the trim from the front panel from under the steering wheel.
11. Unfasten the unit and disconnect its electrical connector.

12. Remove the glove compartment cover (chapter 11 paragraph 32).
13. Carefully push out the sensor with a small screwdriver.
14. Remove the back cover and disconnect the electrical connector (see Fig. 19.14).
Low Air Temperature Indicator Sensor
15. Remove the front bumper.
16. Unfasten the sensor unit and disconnect the electrical connector (see Fig. 19.16).
Engine oil level sensor
17. Apply the parking brake, lift the front end and place it on supports.
18. Place a container under the sensor to catch any oil leaks.
19. Remove the screws and remove the sensor cover.
20. Disconnect the electrical connector.
21. Unscrew and remove the sensor. Remove the seal (see Fig. 19.21).
22. After installing the sensor, add oil to the engine (see "Weekly checks").
Open door alarm microswitch
23. Remove the door lock (chapter 11 paragraph 14).
24. Detach the sensor and disconnect the electrical connector.
Low Coolant Level Indicator Sensor
25. See. chapter 3 paragraph 6.
Low Washer Fluid Indicator Sensor
26. Disconnect the electrical connector on the washer reservoir.
27. Use a syringe to suck out the liquid from the tank.
28. Use a screwdriver to push the sensor out of the tank (see Fig. 19.28).
29. After installing the sensor, add fluid to the tank (see "Weekly checks").
Brake pad wear sensors
30. The sensor wires are located in the friction lining material. When this material wears out, the wire is "exposed" and contacts the brake disc, closing the circuit of the brake pad wear indicator. Damage to the insulation of the sensor wires can cause a false signal from the wear indicator.
