The sunroof of the Mercedes E-Class (4th gen, W212, 2009–2016) offers not only fresh-air comfort but also safety features such as the reversing function, which protects against trapping. Drivers and passengers benefit from well-designed warnings that ensure responsible use of the sunroof. In addition, the rain-sensing closing feature provides extra protection in the event of a sudden change in weather.

Important Safety Notes

Your vehicle may be equipped with a sunroof or a panoramic sunroof. In this section, the term "sunroof" refers to both sunroof variants.

WARNING

When opening and closing, body parts can be trapped in the movement range of the sunroof. There is a risk of injury!

When opening and closing, make sure no body parts are in the movement range.

If someone becomes trapped,
  • release the switch immediately, or
  • during automatic travel, briefly press the switch in any direction.

Opening or closing is stopped.

WARNING

If children operate the sunroof, they can get trapped, especially when unsupervised. There is a risk of injury!

Always take the key with you when leaving the vehicle and lock the vehicle. Never leave children unattended in the vehicle.

NOTE

Only open the sunroof when it is free of snow and ice. Otherwise, malfunctions may occur.

Do not let objects protrude from the sunroof. The seals can be damaged.

Info

When the sunroof is open, resonance noises may occur in addition to the usual wind noise. These are caused by slight pressure fluctuations in the vehicle interior. To reduce or eliminate these noises, change the position of the sunroof or open a side window slightly.

Sunroof reversing function

Your vehicle may be equipped with a sunroof or a panoramic sunroof. In this section, the term "sunroof" refers to both sunroof variants.

The sunroof is equipped with an automatic reversing function. If a solid object prevents or restricts the sunroof from closing during the closing process, the sunroof automatically opens again. The automatic reversing function is only an aid and does not replace your attention when closing the sunroof.

WARNING

In particular, the reversing function does not respond

  • to soft, light and thin objects, e.g. small fingers
  • during the last 4 mm of the closing travel
  • during adjustment
  • when the sunroof is closed manually again immediately after automatic reversing.

As a result, the reversing function cannot prevent pinching in these situations. Risk of injury!

When closing, make sure that no body parts are within the closing area.

If someone becomes trapped,
  • release the switch immediately, or
  • during automatic closing, briefly press the switch in any direction.

The closing process is stopped.

The sunshade opens automatically when the sunroof is opened. You can open or close the sunshade manually when the sunroof is tilted or closed.

Info

If you switch off the engine or remove the key, you can still operate the sunroof. This function is available for five minutes or until you open a front door.

Rain-sensing closing

If the key is in position 0 in the ignition lock or has been removed, the sunroof closes automatically
  • when rain begins
  • in extreme outside temperatures
  • after six hours
  • in case of power supply faults

To continue ventilating the vehicle interior, the sliding roof then lifts at the rear.

Info

If the sliding roof closes with the "Rain closing" function and is blocked in the process, it reopens slightly. The "Rain closing" function is then deactivated.

The sliding roof does not close if it

  • is raised at the rear
  • is blocked
  • it is not raining on the rain sensor's sensor field in the windshield. If the vehicle is parked, for example, under a bridge or in a carport, the sensor field may be covered.

Adjusting

Note

If the sliding roof cannot be fully opened or closed after adjusting, contact a qualified workshop.

If the sliding roof can only be moved in jerks, readjust it.

Turn the key in the ignition to position 1 or 2.

Fully raise the sliding roof at the rear.

The buttonkeep pressing for another second.

Check that the sliding roof can be fully opened and closed again.

If this is not the case, repeat the steps above.

The sliding roof of the Mercedes E-Class W212 (model years 2009–2016) impresses with its reversing function and clever safety solutions. If an obstacle is detected, the closing process is stopped to prevent injuries. Nevertheless, attentiveness while operating it remains the top priority.

Additional features such as rain closing and easy adjustment of the sliding roof underline the high comfort and safety standards of the E-Class W212.

The sliding roof thus combines technology and safety at the highest level and offers real added value in everyday use.
