WHICH MERCEDES MODELS HAVE SELF-LEVELING SUSPENSION?

Riding a Mercedes automobile is so enjoyable, you get a comfortable ride no matter the road surface and other factors. But do you know what determines your comfortable rides? Yes, it’s suspension, the main part of any vehicle.

If you plan to buy a car, you should have some knowledge, which details should be taken into consideration for making a good decision. I know it can be boring to search about vehicle parts and learn technical details, for that reason I offer you only the most important details that can help you.

I’ll assist you to find out all the needed information about the self-leveling suspension that plays the main role in a vehicle. You will learn, which Mercedes models work with the suspension system, how to determine whether an automobile has the system, or not, how the system works, what is the must-have tool for Mercedes, and how to adjust car level in seconds. As you can see, there are many interesting topics, so let’s start exploring!

How does the self-leveling suspension work?

Before finding out which Mercedes models have an auto-leveling suspension, let’s realize what is meant under the term, and how it works. In simple words, self-leveling suspension means that an automobile keeps the same height even-if there is a heavy load on it. Due to the system, we can enjoy comfortable rides no matter the load. It’s amazing, isn’t it?

So, how does the system manage to maintain a constant level even with a heavy load? The system uses air compressors or pumps and air bags. With the help of electronic sensors, located on the chassis, the self-leveling suspension is activated or deactivated upon the need. Upon the sensors, the air compressors or air pumps, pump into, or bleed the air off. That action determines increasing and decreasing the level of chassis, both front and rear as well as left and right.

Main parts of self-leveling suspension

As we already have a very generic view about the auto leveling suspension, let’s dive in a bit deeper and explore its main parts and how they are connected to each other.

The system includes 5 components: Pump, Fluid Reservoir, Leveling Valve, Accumulators, and Struts. Each component is crucially important. For instance, a pump provides pressure for lifting the rear part; struts work like a normal shock for dampening bumps; fluid reservoir keeps the fluid level.

All of the five components are very important, I’d say that the leveling valve is outstanding. It determines whether to raise or lower the rear part.

The system has changed and developed over the years. Nowadays, modern automatic levelling suspension work on air bags, while in the past the system used air-operated shock for adjusting the automobile level.

Nonetheless, the air-operated shocks worked well as leveling components, they failed to provide a comfortable and smooth ride with a full-load capacity. The air bags easily make inflation adjustments through the automobile’s computer. The computer system checks car height several hundred times per second while in motion. Hence the air bags are considered as a more durable and long-lasting alternative, than the air-operated shocks.

Mercedes models with the self-leveling suspension

Self leveling suspension for Mercedes

Did you know that the first automobile with rear self-adjusting suspension was released by Citroën in France, in 1954? Since then, many manufacturers started releasing automobiles with the system, and the exception was not Mercedes.

The self-leveling system also is referred to as airmatic suspension for Mercedes models. Here is the list of Mercedes models with the airlift system.

GLE Coupe

The air suspension with the Adaptive Damping System Plus (ADS+) is optionally available. The optional air suspension is sportier. It offers a sensitive response, maintains the ground clearance nonetheless of the load, and adapts variably to the driving situation.

CLS Coupe

Comfortable ride at CLS Coupe is guaranteed by the airmatic system that controls the ride height automatically according to the speed.

The suspension system also reduces fuel consumption by reducing the height of a car. It has 3 modes and levels change accordingly:

  • Normal – Comfort driving mode;
  • Lowered – In ECO, Sport, and Sport+ (or at speeds above 138 km/h) modes the level reduces by -15mm;
  • Raised – You can select that level in any mode, but only at speeds up to 120 km/h for handling safety reasons. In raised mode, your car height increases by +15mm;

S-Class

With the help of a self-leveling suspension, vehicle level lowers by -10 mm when driving at a higher speed. It has two modes “Sport” and “Comfort” and can be raised up to +40mm on a damaged road.

GLS SUV

Airmatic suspension uses sensors and algorithms to analyze the driving situation and make automatic adjustments. Hence, you don’t need to select manually the mode, upon the road conditions.

S-Class Maybach

The air suspension system adjusts the damping power at every wheel, hence it adapts to any condition of the road.

Even if you already own a car and not sure in its technical details, you can clarify whether it has an airmatic suspension system or not.

Adjusting the height of a self-leveling suspension

How does self leveling suspension work?

Now since you know how the auto-leveling suspension works, which Mercedes models work with the system, what advantages it offers, I want to introduce you to the must-have tool for your automobile.

As you know the airmatic system offers automatic adjustment of a vehicle level, but did you know that you could do it manually? The important thing is that you can lower, or raise the rear and front sides of an automobile in seconds!

The Mercedes lowering tool is designed specifically for the auto leveling suspension system and works via OBD II diagnostic port. It’s simple to use for any car owner, no experience or knowledge of vehicles required.

Plug and play module doesn’t require cutting or soldering any wires. For using the feature, you should simply plug in the module at diagnosis, and that’s it. It’s ready!

The module has 3 different modes

  • Factory – By choosing the mode, car level goes back to factory settings;
  • Low – The Low option gives you the possibility to lower your car with -32mm in the front and rear parts.
  • Custom – By selecting this feature you can select preferable height upon your wish for the front and rear parts separately (Min -70mm; Max +40mm;)

Reasons to use the Mercedes lowering device

I know it’s hard to decide whether it’s worth buying or not a new device, until you test it on your automatic levelling suspension automobile. But let me share with you shortly about the benefits that the device offers.

  • By using the tool, you can change the look of your vehicle in seconds. You can either raise or lower the height upon your wish.
  • And the change can be not just attention-grabber, but useful as well. For instance, if you plan to spend your vacation in a mountainous area, but don’t own an SUV, you can simply increase the height of a car and solve the issue.
  • By lowering an automobile, you get less rollover risk and improved responsiveness. It’s a well-known fact that you get a faster acceleration and quicker stops in lowered suspension.

So, now it’s your turn to test and explore the more benefits of the tool!

Conclusion

All in all, nonetheless all of the above-mentioned information might seem overwhelming, hopefully you have found it interesting. As agreed, we’ve covered topics related to the self-adjusting suspension, learned how it works, what components it includes, which Mercedes models work with the same system and explored the must-have lowering tool. I’m sure after reading all those details you are ready to test the tool on your car!
