Rear Suspension Height Adjustment Pneumatic System — General Information (Opel Astra G)

1. The system is provided on some models with a station wagon body. The height of the car is adjusted by supplying compressed air to the rear shock absorbers through a valve in the right rear part of the luggage compartment.

2. It is not allowed to bring the pressure in the system to the maximum on an unloaded vehicle.

3. The pressure in the pneumatic system is adjusted in the following order. On an unloaded car, check the pressure in the system using a tire pressure gauge, which should not be lower than 0.8 atm (0.08 MPa). Place the car on a flat, hard surface, measure the distance between the lower edge of the rear bumper and the surface. Subtract 40 mm from the measured value. Load the car and increase the pressure in the system until the distance from the bumper to the surface is equal to the result obtained. The pressure should not exceed 5 atm (0.5 MPa).

4. After unloading the vehicle, release the pressure to 0.8 atm.
