2007 BMW Z4 Owner's Manual - Page 24

Special operating instructions Special operating instructions Break-in procedures In contrast to the descriptions in the Owner's Manual for the BMW Z4, please take note of the following differences for your BMW Z4 M Roadster/Z4 M Coupe. Always obey all official speed limits. Driving notes Ground clearance The front spoiler greatly restricts the vehicle's ground clearance. Make sure that your BMW always has sufficient ground clearance, e.g. when entering underground garage complexes or driving over the edge of a curb; otherwise the front spoiler could be damaged.< Engine and differential Up to 1,200 miles/2,000 km Drive at varying engine and road speeds, but do not exceed 5,500 rpm or 100 mph/170 km/h. Strictly avoid depressing the accelerator pedal to full-throttle position. After the breaking-in inspection at 1,200 miles/ 2,000 km, engine or road speeds can be gradually increased. Braking safely In contrast to the descriptions in the Owner's Manual for the BMW Z4, your BMW Z4 M Roadster/Z4 M Coupe is equipped with perforated brake discs. In certain braking situations, operation of the perforated brake discs can cause noise; however, this does not affect the performance and operating safety of the brakes. Transmission The function of the transmission reaches its optimal level only after driving a distance of approx. 300 miles/500 km. Do not exceed engine speeds of 5,500 rpm during this time. 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. 22 Online Edition for Part-No. 01 41 0 012 046 - © 04/06 BMW AG
