Initialization

The initialization process adopts the set inflation
tire pressures as reference values for the detec‐
tion of a flat tire. Initialization is started by con‐
firming the inflation pressures.


Do not initialize the system when driving with
snow chains.

Indication of a flat tire

The yellow warning lamp lights up. A
Check Control message is displayed.
There is a flat tire or a major loss in tire
inflation pressure.



  1. Reduce your speed and stop cautiously.
    Avoid sudden braking and steering maneu‐
    vers.

  2. Check whether the vehicle is fitted with reg‐
    ular tires or run-flat tires.
    Run-flat tires, refer to page 181, are labeled
    with a circular symbol containing the letters
    RSC marked on the tire sidewall.


Do not continue driving without run-flat
tires
Do not continue driving if the vehicle is not
equipped with run-flat tires; continued driving
may result in serious accidents.◀

When a flat tire is indicated, DSC Dynamic Sta‐
bility Control is switched on if necessary.

System limits

Sudden tire damage
Sudden serious tire damage caused by
external influences cannot be indicated in ad‐
vance.◀

A natural, even pressure loss in all four tires can‐
not be detected. Therefore, check the tire infla‐
tion 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.

Actions in the event of a flat tire

Normal tires


  1. Identify the damaged tire.
    Do this by checking the air pressure in all
    four tires.
    If the tire inflation pressure in all four tires is
    correct, the Flat Tire Monitor may not have
    been initialized. In this case, initialize the
    system.
    If an identification is not possible, please
    contact the service center.

  2. Rectify the flat tire.
