Level control system — description

1. This system is only installed on some models and its function is to compensate for the effect on the rear suspension due to the vehicle being loaded with heavy loads or used as a tow.

2. This system operates by varying the air pressure in the rear shock absorbers. On some models, system pressure is automatically regulated, while on others (which is more common) the pressure can be adjusted manually.

3. When a fully automatic system is installed, the source of compressed air is an electrically driven compressor, and the driver does not need to do anything. The level change response occurs after 20 seconds to prevent the system from being activated when driving over bumps.

4. The diagram of the automatic level control system and the location of the various components are shown in Fig. 10.33.

5. On this more common system, a compressed air line is connected to a coupling inside each shock absorber at the rear. The two hoses combine into one, which passes through the side panels of the housing to the control valve (similar to a tire pressure valve) in the rear of the body. The location of this valve varies depending on the model, but this location should be either in the luggage compartment or in the rain channel on the right rear corner (access with open trunk lid).
