Things to remember when driving Things to remember when driving Break-in procedures Moving parts need to be given some time until they can interact smoothly with one another. To ensure that your vehicle provides maximum economy throughout a long service life, we request that you observe the following. Always obey all official speed limits. After replacing components The same break-in procedures should be observed if any of the components mentioned above have to be renewed in the course of the vehicle's operating life. Saving fuel The fuel consumption of your vehicle depends on several factors. You can lower fuel consumption and the environmental impact by taking certain measures, adjusting your driving style and having the vehicle serviced regularly. Engine and differential Up to 1,200 miles/2,000 km Drive at varying engine and road speeds, but do not exceed 4,500 rpm or 100 mph/160 km/h. Refrain from using full throttle and avoid pressing the accelerator beyond the kickdown point. Remove any unneeded cargo Additional weight increases fuel consumption. After driving 1,200 miles/2,000 km Engine and vehicle speeds can be gradually increased. Remove any mounted parts after you have finished using them Remove additional mirrors and the luggage rack when they are no longer in use. Mounted parts affect the vehicle's aerodynamics and increase fuel consumption. Tires Due to technical factors associated with their manufacture, tires do not achieve their full traction potential until an initial break-in period has elapsed. Therefore, drive cautiously during the first 200 miles/300 km. Close both windows Open windows cause higher air resistance and thus increase fuel consumption. 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 cautiously during this break-in period. Check tire inflation pressure regularly Check the tire inflation pressure at least twice a month and before embarking on a long journey, and correct it if necessary. Low tire inflation pressure causes higher rolling resistance and thus increases fuel consumption and tire wear. Clutch The function of the clutch reaches its optimal level only after a distance driven of approx. 300 miles/500 km. Shift gears carefully during the break-in period. Set off immediately Do not let the engine warm up while the car is still standing, but set off immediately at moderate engine speed. This is the fastest way for the cold engine to reach its operating temperature. 74 Online Edition for Part no. 01 41 0 014 500 - © 08/07 BMW AG
