Technology for comfort, convenience and safety longer holds the vehicle after approx. 2 seconds and it begins to roll back.< The initialization must be repeated after each time the tire inflation pressure is corrected and after every tire or wheel change.< Self-leveling suspension* Malfunction The warning lamp for self-leveling suspension lights up yellow and a message is shown on the Control Display. A malfunction has occurred in the selfleveling suspension. Stop and check the vehicle. If it is considerably lower at the rear than at the front, and possibly also on one side - rear left compared to rear right -, proceed to the nearest BMW Sports Activity Vehicle Center or a workshop that works according to BMW repair procedures with correspondingly trained personnel. Drive with appropriate caution in the meantime. The vehicle has reduced ground clearance and driving comfort may be noticeably reduced. Even if the orientation of the vehicle is normal, when a malfunction is indicated on the display, you should proceed to the nearest BMW Sports Activity Vehicle Center or a workshop that works according to BMW guidelines and uses appropriately trained personnel. 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 snowy or slippery road surface > Sporty driving style: slip in the drive wheels, high lateral acceleration > Driving with snow chains* When you are driving with the compact wheel* the Flat Tire Monitor is unable to function. Initializing system The initialization finishes during driving, which can be interrupted at any time. When driving resumes, the initialization is continued automatically. Do not initialize the system when driving with snow chains* or with the compact wheel*.< 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. 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. Function requirements In order to assure the reliable reporting of a flat tire, the system must be initialized for the correct tire inflation pressure. 4. Select "Vehicle / Tires" and press the controller. 92 Online Edition for Part no. 01 41 0 014 248 - © 08/07 BMW AG
