Rear Suspension Rigidity Control System — Adjustment (Opel Vectra A)

1. After completely unloading the vehicle, install a pressure gauge on the air valve and make sure that the pressure in the system is 0.8 bar. If not, adjust the pressure.

2. Make sure the car is parked on a level surface and measure the distance from the center of the rear bumper to the ground. Subtract 50.0 mm from the measured distance and record the resulting value.

3. Load the car and, if necessary, increase the pressure in the system until the bumper rises to the height calculated in the previous step. Do not increase the pressure above 5.0 bar.

4. After unloading the vehicle, release the pressure in the system (but not less than 0.8 bar), to achieve the originally measured bumper height.

5. Do not operate an unloaded vehicle without relieving the pressure in the system.
