Things to remember when driving74Things to remember when drivingBreak-in proceduresMoving 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.Engine and differentialUp to 1,200miles/2,000kmDrive 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 press-ing the accelerator beyond the kickdown point.After driving 1,200miles/2,000kmEngine and vehicle speeds can be gradually increased.TiresDue to technical factors associated with their manufacture, tires do not achieve their full trac-tion potential until an initial break-in period has elapsed. Therefore, drive cautiously during the first 200 miles/300 km.Brake systemBrakes 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.ClutchThe 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.After replacing componentsThe 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 fuelThe fuel consumption of your vehicle depends on several factors. You can lower fuel consump-tion and the environmental impact by taking certain measures, adjusting your driving style and having the vehicle serviced regularly.Remove any unneeded cargoAdditional weight increases fuel consumption.Remove any mounted parts after you have finished using themRemove additional mirrors and the luggage rack when they are no longer in use. Mounted parts affect the vehicle's aerodynamics and increase fuel consumption.Close both windowsOpen windows cause higher air resistance and thus increase fuel consumption.Check tire inflation pressure regularlyCheck 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.Set off immediatelyDo not let the engine warm up while the car is still standing, but set off immediately at moder-ate engine speed. This is the fastest way for the cold engine to reach its operating temperature.
