Since 1988 the index of pressure of oil in a combination of devices is replaced with ekono-meter. Control lamps of level of brake fluid and fog light are taken out from a combination of devices and placed in separate cases under a middle part of the dashboard. Instead of them in a combination of devices the control lamp of the air gate of the carburetor and insufficient pressure of oil are installed in the engine lubrication system.
