Air Springs

The air spring is made from a flexible rubber material. It forms an air tight cavity which provides the calculated spring rate required for the sport wagon.

As the spring compresses downward the bottom edge of the rubber material rolls along the vertical surface of the base mount cylinder.

Air is added or removed from the air spring through its top port. The top port of each spring is connected to a reser- voir and the air supply pipes. The reservoirs are required to hold additional air due to the compact design of the springs.

Rear Axle Level Sensors

Hall effect sensors are mounted on the left and right sides of the rear suspension for ride height detection. They are pivoted by a cou- pling rod through the rear axle swing arms.

The hall sensors produce a varying voltage input to the control module as the suspension height changes.

If the vehicle is equipped with Xenon head- lights the right side sensor contains an addi- tional sensor for the automatic headlight level adjustment system.
