Technology for driving comfort and safety The drive-off assistant holds the car in place for approx. 2 seconds after the brake is released. Depending on vehicle load, the car may roll backwards a little during this time span. Drive off without delay after releasing the brake. Otherwise, the drive-off assistant will no longer hold the car in place after approx. 2 seconds and the car will start to roll backwards.< Initializing the system The initialization is completed during driving, which can be interrupted at any time. When driving resumes, the initialization is continued automatically. Do not initialize the system while snow chains are attached.< iDrive, for operating principle refer to page 16. 1. Press the button. This opens the start menu. 2. Press the controller to open the menu. 3. Select "Settings" and press the controller. Flat Tire Monitor FTM* The concept The Flat Tire Monitor monitors tire pressures while the car is being driven. The system reports any significant loss of pressure in one tire in relation to another. If a tire loses pressure, its rolling radius changes, and this in turn alters the speed of rotation. This change is detected and is reported as a flat tire. Functional requirement In order to assure the reliable reporting of a flat tire, the system must be initialized for the correct tire inflation pressure. The system must be reinitialized each time a tire inflation pressure has been corrected or a wheel or tire has been changed.< 4. Select "Vehicle / Tires" and press the controller. 5. If necessary, move the highlight marker to the uppermost field. Turn the controller until "FTM" is selected and press the controller. System limitations The Flat Tire Monitor is unable to warn the driver of sudden, severe tire damage caused by external factors, nor can it identify the gradual loss of pressure that will inevitably occur in all four tires over a lengthy period of time.< In the following situations, the system could be delayed or malfunction: > System has not been initialized > Driving on snowy or slippery road surface > Performance-oriented style of driving: slip in the drive wheels, high lateral acceleration > Snow chains are attached 6. Start the engine, but do not start driving. 7. Select "Reset" and press the controller. 92 Online Edition for Part no. 01 41 0 013 670 - © 02/07 BMW AG
