Tires

~3min read

The tire pressure monitoring systems of the Mercedes E-Class (4th generation, W212, 2009–2016) contribute significantly to driving stability. This section explains warning messages for pressure loss and gives clear recommendations for avoiding accidents. This keeps the vehicle as controllable as possible, even in the event of a tire defect.

Display messages Possible causes/consequences and solutions
Tire pressure Check tires The tire pressure loss warning has detected a significant pressure loss.

A warning tone also sounds.

Possible cause:
  • You have changed the wheels and tires or fitted new wheels and tires.
  • The tire pressure of one or more tires is not correct.
WARNING

Driving on tires with insufficient tire pressure involves the following risks:

  • Tires may burst, especially with increasing load and speed.
  • Tires may wear excessively and/or unevenly, which can significantly reduce tire grip.
  • Handling, steering and braking behavior may be severely impaired.
There is a risk of accidents!

Stop without sudden steering or braking maneuvers. Take traffic conditions into account.

Secure the vehicle against rolling away.

Check the tires and, if necessary, follow the instructions for a tire puncture.

Check the tire pressure and, if necessary, correct the tire pressure.

Then, once the tire pressure is set correctly, restart the tire pressure loss warning.

Restart tire pressure monitoring after checking the pressure A tire pressure loss warning message was shown in the display and the system has not been restarted since.

Set the correct tire pressure on all tires.

Restart the tire pressure loss warning.

Tire pressure monitoring not functioning The tire pressure loss warning is defective.

Consult a qualified specialist workshop.

Correct tire pressure The tire pressure on at least one tire is too low, or the tire pressures of the individual wheels differ too much.

Check the tire pressure at the next opportunity.

If necessary, correct the tire pressure.

Restart the tire pressure monitoring.

Check tires The tire pressure of one or more tires has dropped significantly. The wheel position is shown in the multifunction display.

A warning tone also sounds.

Check the tire pressure.

If necessary, correct the tire pressure.

Warning: tire defect The tire pressure of one or more tires is suddenly dropping. The wheel position is shown to you in the multifunction display.

WARNING

Driving with a tire that has no pressure involves the following risks:
  • A tire with no pressure impairs the vehicle's steering and braking ability.
  • You could lose control of the vehicle.
  • Continuing to drive on a tire with no pressure leads to excessive heating and possibly a fire.
There is a risk of accidents!

Stop without sudden steering or braking maneuvers. Take traffic conditions into account.

Secure the vehicle against rolling away.

Check the tires and, if necessary, follow the instructions for a tire puncture.

Tire pressure monitoring currently unavailable A strong radio source is interfering, so no signals from the tire pressure sensors are being received. Tire pressure monitoring is temporarily disrupted.

Continue driving.

  • As soon as the cause is removed, tire pressure monitoring switches on automatically.
  • Wheel sensor missing The signal from the tire pressure sensor is missing for one or more tires. No pressure value is shown in the multifunction display for the affected tire.

    Have the defective tire pressure sensor replaced at a qualified workshop.

    Tire pressure monitoring not functioning, wheel sensors missing The fitted wheels do not have suitable tire pressure sensors. Tire pressure monitoring is switched off.

    Fit wheels with suitable tire pressure sensors.

  • Tire pressure monitoring switches on after a few minutes of driving.
  • Tire pressure monitoring not functioning Tire pressure monitoring is defective.

    Consult a qualified specialist workshop.

    The tire pressure monitoring system of the Mercedes E-Class W212 (model years 2009–2016) reliably warns of pressure loss and helps prevent accidents. It clearly indicates deviations and thus supports safety and driving comfort.

    By regularly checking the tire pressure and heeding warning messages, the vehicle stays safe and efficient on the road.
