What is air suspension?

Before discussing the steps to address this Immediate Air Suspension Service Required warning, let’s explore air suspension and how it works.

The air suspension is an improved version of the standard suspension. It was developed to provide a more accessible and comfortable driving experience.

Air suspension functions differently from traditional suspension. Instead of steel coil springs, the air suspension utilizes air-filled rubber bags, also known as air springs. They take on road bumps and vibrations, giving you an easy ride. Air springs are used alongside other components, such as an air compressor, height and pressure sensors, and an air reservoir.

A control module monitors each air spring’s air pressure. If the pressure drops, the air is pumped to the specific spring, which raises the height of your vehicle. In contrast, when the pressure gets excessively high, a valve lets air out while maintaining the balance. It offers many benefits, including a more comfortable ride over rough terrain, better handling, and increased durability.

Even when you are hauling many items in the rear of your car, the air suspension ensures that your vehicle stays at the right level to drive at.

The Jeep Grand Cherokee has a unique air suspension. Its four-way lift system allows for adjustable Jeep height to suit different driving conditions and does not require slowing down the Jeep.
