4.0 Checking Transmission Fluid Level: Notes
WARNING: This page does not describe the selected car, but rather 158 other vehicles, including the 2014 BMW i8, 2014 BMW i3, 2014 BMW X6 M, 2014 BMW X6, and 2014 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.
Due to the substantial expansion of transmission fluid when heated it is only possible to measure the oil level correctly at specified oil temperatures (after driving a distance of about 12 mi./20 km).
