Things to remember when driving Things to remember when driving Breaking-in Moving parts need time to adjust to one another. To ensure that your vehicle continues to furnish optimized economy of operation throughout an extended service life, we request that you devote careful attention to the following information. General driving notes Closing luggage compartment lid Operate the vehicle only when the luggage compartment lid is completely closed. Otherwise, exhaust fumes could penetrate into the passenger compartment.< If special circumstances should make it absolutely necessary to operate the vehicle with the luggage compartment lid open: 1. Close all windows and the glass sunroof. 2. Adjust the automatic climate control's blower to supply a high rate of airflow, refer to page 106. Engine and differential Always obey all official speed limits. Up to 1,200 miles/2,000 km Drive with changing engine and vehicle speeds, but do not exceed: 4500 rpm or 100 mph/160 km/h Avoid full-throttle operation and use of the transmission's kick-down mode during these initial miles. Hot exhaust system As in all vehicles, extremely high temperatures are generated in the exhaust system. Do not remove the heat shields installed adjacent to it, and never apply undercoating to them. When driving, standing at idle, and parking, take care to avoid possible contact between the hot exhaust system and any highly flammable materials such as hay, leaves, grass, etc. Such contact could lead to a fire, accompanied by the risk of serious property damage and personal injury.< After 1,200 miles/2,000 km The engine and vehicle speed can gradually be increased. Tires Due to technical factors associated with their manufacture, tires do not achieve their full traction potential until after an initial break-in period. Therefore, drive reservedly during the first 200 miles/300 km. Mobile communications devices in vehicle BMW does not recommend using mobile communications devices, e.g. mobile phones, inside the vehicle without a direct connection to an outside antenna. Otherwise, the vehicle electronics and mobile communications device can interfere with each other. In addition, there is no assurance that the radiation which results during transmission will be discharged from the vehicle interior.< Brake system Brakes require an initial break-in period of approx. 300 miles/500 km to achieve optimized contact and wear patterns between brake pads and rotors. Following component replacements Follow the break-in sequence again if components addressed above must be replaced again during subsequent driving. 122 Online Edition for Part no. 01 41 0 013 316 - © 02/07 BMW AG
