What is air suspension?

As a starting point, it is important to discuss what is air suspension and how does it differ from traditional suspension systems? The main difference between a traditional shock or strut is that they have a dampening mechanism set to a certain ride control feel while an air suspension system uses an air compressor in combination with air struts and suspension air bags to control the feel of the ride.

Air suspension has several advantages over traditional shocks and struts. The first is that the ride quality is often controlled by the driver of the vehicle. Therefore, if you want a softer ride you can set your air suspension system to deliver that and vice versa if you are looking for a stiffer, rougher ride. The second advantage is that you can control ride height, some systems are advanced in that they automatically control this for you. The final advantage of an air suspension system is weight management. If you load the back of your SUV with a large amount of groceries from the store, the air suspension system either automotically adjusts to handle it or you can manually adjust it. For traditional shocks and struts the level of rebound is set and therefore no matter what the weight of your load is, you have to stick with it. This often creates a sagging rear end when carrying a heavy load.

What does ADS mean on a Mercedes-Benz?

On vehicles equipped with an Adaptive Damping System in addition to Airmatic (automatic vehicle height adjustment), the driver can select the suspension stiffness (ride quality) at a push of a button. Mercedes with ADS has a button on the center console that allows them to select the stiffness of the suspension. Typically you have three settings.

Sport - Suspension becomes very stiff.

Normal -

Comfort - Very soft suspension, you feel like driving a Lexus.

If your Mercedes does not have ADS, you can not adjust the stiffness of the suspension. The vehicle adjusts the ride height automatically, or you can raise the vehicle. But that does not change the stiffness of the suspension.

Having used an R500 with ADS, my preferred setting is NORMAL. Sport makes you feel every little bump on the road. Simultaneously, the COMFORT setting feels as the car needs new struts and there is too much bouncing. The soft setting is good if you drive in a city with bad roads, but the downside is that it can shorten the life of the airbags. In Comfort ADS settings, the suspension airbags move up and down the most.

How can I determine if my Mercedes has ADS?

There are two straightforward ways to determine if your Mercedes-Benz has ADS.

First, you have a button on the dashboard to adjust the ride quality. The button shows a shock and has the words "SPORT" and "COMF" written.

A car without ADS will not have this button. Cars with airmatic, but no ADS, still have a button to raise the vehicle.

Second, the airmatic structs in vehicles with ADS have a solenoid installed next to the airmatic strut that is not installed on cars without ADS.
