The small warning lamp lights up yellow and the large warning lamp lights up red. A message appears on the Control Display. In addition, a signal sounds.

▷ There is a flat tire or a major loss in tire inflation pressure.
▷ The system was not reset after a wheel change and thus issues warnings based on the inflation pressures initialized last.

Reduce your speed and stop cautiously. Avoid sudden braking and steering maneuvers.

When a low inflation pressure is indicated, DSC Dynamic Stability Control is switched on if necessary.
