What To Know

  • Once the vehicle is raised to the desired height, carefully position the jack stands under the designated lifting points.
  • Once the jack stands are firmly in place, slowly lower the jack until the vehicle is resting securely on the stands.
  • Before lowering the vehicle, raise it slightly using the jack to ensure the jack stands are clear of the lifting points.

Are you ready to tackle those undercarriage repairs or tire changes on your Mercedes with air suspension? Knowing how to properly jack up your car is crucial for any DIY enthusiast, but air suspension adds a layer of complexity. Fear not! This comprehensive guide will equip you with the knowledge and techniques to confidently lift your Mercedes without damaging its sophisticated suspension system.

The Importance of Proper Technique

Before diving into the steps, it’s essential to understand why proper technique is paramount when working with air suspension. Unlike traditional coil spring systems, air suspension relies on pressurized air to adjust ride height. This means:

  • Risk of Damage: Incorrect lifting can put undue stress on the air struts, leading to leaks, damage, or even failure.
  • Safety Concerns: A poorly supported vehicle can become unstable, posing a serious safety hazard.

Step 1: Gather Your Tools and Supplies

To ensure a smooth and safe jacking experience, make sure you have the following:

  • Mercedes-Benz Approved Jack: Using a jack specifically designed for your Mercedes is crucial. These jacks are engineered to accommodate the unique lifting points and suspension system.
  • Jack Stands: Never rely solely on the jack. Always use jack stands to securely support the vehicle once lifted.
  • Lug Wrench: You’ll need this to remove the lug nuts.
  • Air Compressor (Optional): If you plan to adjust the air suspension, having an air compressor handy is beneficial.
  • Safety Glasses and Gloves: These protect your eyes and hands from potential hazards during the process.

Step 2: Prepare the Vehicle for Lifting

  • Park on a Flat, Level Surface: Ensure the vehicle is parked on a solid, level surface to prevent it from rolling.
  • Engage the Parking Brake: Set the parking brake firmly to prevent the vehicle from moving.
  • Disable the Air Suspension System: This step is crucial to prevent the suspension from automatically adjusting while you’re lifting the vehicle. Consult your owner’s manual for the specific procedure on your Mercedes model. The process typically involves:
  • Disengaging the Air Suspension Control: Locate the air suspension control switch (often found in the center console or trunk) and disable the system.
  • Depressurizing the Air Struts: Some models allow you to manually depressurize the air struts using a valve located near the suspension components.

Step 3: Locate the Lifting Points

  • Consult Your Owner’s Manual: Your owner’s manual will clearly indicate the designated lifting points on your specific Mercedes model. These points are typically located at the front and rear of the vehicle, usually marked by a small indentation or a raised area.
  • Avoid Lifting from Unsuitable Points: Never attempt to lift the vehicle from any area other than the designated lifting points. Lifting from other areas can cause damage to the suspension, bodywork, or undercarriage.

Step 4: Position the Jack and Raise the Vehicle

  • Place the Jack Under the Designated Lifting Point: Carefully position the jack under the designated lifting point, ensuring it is securely positioned and centered.
  • Start Lifting Slowly and Gradually: Begin lifting the vehicle slowly and gradually, monitoring the movement. Avoid sudden or jerky movements that could strain the suspension or damage the jack.
  • Raise the Vehicle to the Desired Height: Lift the vehicle until it is high enough to provide sufficient clearance for your work. Remember to keep the jack stands nearby and ready to be placed.

Step 5: Secure the Vehicle with Jack Stands

  • Position the Jack Stands: Once the vehicle is raised to the desired height, carefully position the jack stands under the designated lifting points. Ensure the stands are securely positioned and firmly engage with the lifting points.
  • Lower the Jack: Once the jack stands are firmly in place, slowly lower the jack until the vehicle is resting securely on the stands.

Step 6: Perform Your Work

  • Proceed with Your Task: Now that the vehicle is securely supported, you can safely perform your work, such as changing a tire, inspecting the undercarriage, or making repairs.
  • Safety First: Always exercise caution and follow safety guidelines while working under the vehicle.

Step 7: Lower the Vehicle and Re-Engage the Air Suspension

  • Raise the Vehicle Slightly: Before lowering the vehicle, raise it slightly using the jack to ensure the jack stands are clear of the lifting points.
  • Lower the Vehicle Slowly: Carefully lower the vehicle until it is resting on the ground.
  • Re-Engage the Air Suspension: After lowering the vehicle, re-engage the air suspension system by following the steps outlined in your owner’s manual. This will allow the suspension to automatically adjust to the correct ride height.

A Smooth Ride: Final Thoughts

Knowing how to jack up a Mercedes with air suspension is a valuable skill for any owner. By following these steps and prioritizing safety, you can confidently perform undercarriage tasks on your Mercedes without compromising its sophisticated suspension system. Remember to consult your owner’s manual for specific instructions tailored to your model and always exercise caution when working with a raised vehicle.
