Things to remember when driving Things to remember when driving Break-in period Moving parts need breaking-in time to adjust to each other. To ensure that your vehicle continues to provide optimized economy of operation throughout an extended service life, we request that you devote careful attention to the following section. General driving notes Closing liftgate/tailgate Operate the vehicle only when the tailgate and liftgate are completely closed. Otherwise, exhaust fumes could enter into the passenger compartment.< However, if special circumstances should make it absolutely necessary to operate the vehicle with the liftgate/tailgate open: 1. Close all windows and the panorama glass sunroof. 2. Increase the air volume of the automatic climate control to a high level, refer to page 103. Engine and differential Always obey all official speed limits. Up to 1,200 miles/2,000 km Drive at changing engine and vehicle speeds, however do not exceed 4,500 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 on 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 while 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, and with it the risk of serious property damage as well as personal injury. Do not touch hot tailpipes, as otherwise there is a danger of burns.< From 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. 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. Drive in a reserved manner during this break-in period. Mobile communications devices in vehicle BMW discourages the use of mobile communications devices, e.g. mobile phones, inside the vehicle without a direct connection to an outside antenna. Otherwise, the vehicle electronics and mobile communication device can influence one another. In addition, there is no assurance that the radiation which results from transmission will be dissipated from the vehicle interior.< Following part replacement Observe the break-in instructions again if components mentioned above must be replaced after subsequent driving operation. 122 Online Edition for Part no. 01 41 0 012 501 - © 08/06 BMW AG
