System limits
Sudden tire damage
Sudden serious tire damage caused by external influences cannot be indicated in advance.
A natural, even pressure loss in all four tires cannot be detected. Therefore, check the tire inflation pressure regularly.
The system could be delayed or malfunction in the following situations:
▷ When the system has not been initialized.
▷ When driving on a snowy or slippery road surface.
▷ Sporty driving style: slip in the drive wheels, high lateral acceleration.
▷ When driving with snow chains.
