Mercedes-Benz Vehicle Elevation: Troubleshooting and Safety Tips

In specific Mercedes-Benz models, a function known as Vehicle Elevation is available. This feature increases the vehicle’s ground clearance by a minimum of 20mm, with some models capable of reaching up to 40mm. If the Vehicle Elevation feature fails, the issue is typically due to a defective fuse, a malfunctioning relay, or an air leak within the suspension system.

Reasons Behind Vehicle Elevation Failures

Mercedes-Benz owners may encounter three primary issues when the Vehicle Elevation feature stops functioning properly.

Defective Fuse

The fuse responsible for the Vehicle Elevation feature varies across Mercedes models, but a 40A fuse is often the correct one. You can replace it yourself with the help of the vehicle’s manual and some patience. Swapping the fuse with a compatible one is straightforward. The fuse regulates the electrical flow from the battery to the system.

Relay Problems

Relay issues are a frequent problem. These occur when the battery supplies insufficient power, the fuse fails to regulate the electrical current properly, or a component in the Vehicle Elevation system lacks adequate power.

In most cases, relay issues with the Vehicle Elevation feature stem from a malfunctioning compressor, which is responsible for inflating the air suspension.

The compressor pumps air into the suspension to raise the vehicle. If it doesn’t receive enough power, it cannot inflate the suspension, preventing the vehicle from elevating.

Replacing a faulty compressor can be costly, with repairs averaging around $1,000.

Air Suspension Leaks

When a Mercedes-Benz transitions from a lowered to an elevated position, the process should take less than 15 seconds. If it takes 20 to 30 seconds for the vehicle to reach its full height, there’s likely an issue with the suspension. Feedback from Mercedes-Benz forums suggests that a slow elevation is often caused by an air leak in the suspension system.

Other indicators of an air leak include the suspension failing to reach its maximum height or unusual squeaking or hissing noises from the vehicle’s undercarriage during elevation.

Repairing an air leak requires professional expertise, as it’s not a task for inexperienced individuals. The cost to fix an air leak in the suspension can reach up to $1,600. Operating a Mercedes-Benz with a compromised suspension is unsafe.

Why Does Your Mercedes-Benz Appear Lower Than Usual?

After being away for a few days, you notice your vehicle appears lower than you recall.

Imagine returning from a five-day or two-week trip to find your Mercedes-Benz sitting lower in the garage.

Rest assured, nothing is damaged. When a Mercedes-Benz remains unused for several days, the suspension naturally lowers to preserve the system. Simply press the Vehicle Elevation button, and the vehicle should return to its normal height in 15 seconds or less.

However, if the vehicle drops to a lowered state overnight after being parked, this could indicate a glitch in the Vehicle Elevation system or an air leak.

What Is Vehicle Elevation and Its Purpose?

To engage the Vehicle Elevation feature, press the elevation button, typically located on the driver’s door or near the climate control and radio controls.

When activated, a “Vehicle Elevating, Please Wait” message may appear on the dashboard or infotainment screen, though this varies by model.

In some Mercedes-Benz models, an elevation indicator light will flash on the dashboard or screen until the vehicle reaches its full height, then disappear.

Once fully elevated, the vehicle’s ground clearance increases by at least 30mm.

Can You Drive Safely at a Lowered Height?

Suppose you must wait a week before a mechanic can repair your Vehicle Elevation feature, leaving your Mercedes-Benz at a lower suspension height.

Is this safe?

Driving at a lowered height is generally safe, but caution is needed to avoid obstacles. You may also risk scraping the vehicle’s undercarriage if navigating steep ramps or uneven surfaces.

Conclusion

The Vehicle Elevation feature increases a Mercedes-Benz’s ground clearance by approximately 30mm, enhancing clearance for obstacles. The elevation process should complete in 15 seconds or less. If it takes longer, potential issues like an air leak or a faulty compressor may be to blame. While driving at a lowered height is safe, operating the vehicle with an air leak in the suspension is not advisable.
