Tire Pressure Monitoring informs the driver of pressure losses at one or more wheels.


Tire Pressure Monitoring (version DDS)

DDS signifies an indirect system. It has no separate sensors. The system is integrated into the ESP control unit. A loss of pressure alters the circumference of the tire and the corresponding wheel turns faster. The ESP control unit detects the change in wheelspeed by way of the rotational speed sensor signal. If tire inflation pressure drops by 0.5 bar the systems issues a warning to the driver.



The following procedure applies if the prerequisites are satisfied:

  • message INIT or the message RESET goes out on the display.


  1. Immediately press the button (2) and keep it pressed for approx. 3 s until the message <INIT> or the message <RESET> (with a tick in each case) appears in the display.
  2. Start the drive.
  3. Drive the vehicle for a few minutes. Choose a route with as many bends as possible to speed up calibration.
  4. Calibration is completed whilst driving without feedback.
  5. Switch off engine.
  6. Tire Pressure Monitor DDS is in calibrated status.



  • The tire pressure has been changed
  • Tires have been replaced or repaired
  • Wheels have been changed or another wheel set is mounted


  1. Start the engine but do not drive off.
  2. Keep moving the rocker (1) up or down until a message equivalent to INIT or RESET appears in the display.
  3. Immediately press the button (2) briefly 1 times.
  4. The arrow symbol to the left of the
