Technology for comfort, convenience and safety FTM Flat Tire Monitor* The concept The Flat Tire Monitor detects a pressure loss in one tire by comparing the speeds of the individual wheels during driving. In the event of a pressure loss, there is a change in the rolling circumference and therefore the rotation speed of the corresponding wheel. The system detects this change and reports it as a flat tire. With Sequential Manual Transmission via the button in the center console: 1. Start the engine, but do not start driving. 2. Press the button for approx. 5 seconds. After the button is released, the warning lamp lights up in yellow for several seconds in the instrument cluster, refer to Indication of a flat tire. The message "Initializing FTM ..." appears on the Control Display for a few seconds. Functional requirement To ensure the reliable signaling of a flat tire, the system must be initialized at the correct tire inflation pressure. The initialization must be repeated after every correction of the tire inflation pressure and after every tire or wheel change.< System limits The Flat Tire Monitor cannot indicate sudden severe tire damage caused by outside factors and does not detect a natural, even pressure drop in all four tires. In the following situations, the system could be delayed or malfunction: > System has not been initialized > Driving on snow-covered or slippery roads > Sporty driving style: slip in the drive wheels, high lateral acceleration > Driving with snow chains* 3. Start to drive. The initialization finishes during driving without feedback. Via iDrive, for operating principle refer to page 16: button. 1. Press the This opens the start menu. 2. Press the controller to open the menu. Initializing system The initialization finishes during driving, which can be interrupted at any time. When driving resumes, the initialization is automatically continued. Do not initialize the system when driving with snow chains*.< 3.
