Special operating instructions68Special operating instructionsBreak-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:Engine and differentialUp to 1,200 miles/2,000 km:Drive at varying engine and road speeds, but do not exceed the following engine or road speed:4,500 rpm / 4,500/min or 100 mph / 160 km/h.Obey your local and state maximum speed lim-its.Refrain from using full throttle and avoid press-ing the accelerator beyo nd the kickdown point.After you have driven 1,200 miles/2,000 km, you can gradually increase the engine or road speeds.Sequential manual gearbox SMGUp to 1,200 miles/2,000 km: Do not use the accelerati on assistant during the break-in period.Tires Due to technical factors associated with their manufacture, tires do no t achieve their full trac-tion potential until an in itial break-in period has elapsed. You should therefore drive with extra caution during the first 200 miles/300 km.Obey your local and state maximum speed lim-its.When the vehicle is operated on wet or slushy roads, a wedge of water may form between the tire and the road surface. This phe-nomenon is referred to as hydroplaning and can lead to partial or comple te loss of traction, vehi-cle control and braking effectiveness. Reduce your speed on wet roads. <Brake systemApprox. 300 miles/500 km must elapse before the brake pads and rotors achieve their optimal surface and wear pattern.To break in the separate parking brake drums, apply the parking brake lig htly when coasting to a standstill - at a traffic signal, for instance; use caution to avoid posing a danger to other road users.To avoid corrosion, repeat this procedure from time to time.The brake lamps do not come on when the parking brake is set.Vacuum for the brake system servo unit on your BMW is available only when the engine is running. When you move the car with the engine off, e.g. by towing, substantially higher levels of pedal fo rce will be required to brake the vehicle.<ClutchThe clutch will achieve it s optimal functionality after approx. 300 miles/500 km. Shift gears carefully during the break-in period.After replacing componentsFollow the same break-in procedure again if any of the components mentio ned above have to be replaced in the future.Driving notes Close the luggage compartment lidOperate the vehicle only when the lug-gage compartment lid is completely closed, otherwise exhaust fumes could pene-trate into the interi or of the vehicle.<Should it be absolutely necessary to operate the vehicle with the luggage compartment lid open and with the convertible top closed:
