I believe the depression near the screwdriver handle is for the "key" to the optional wheel locks. The depression on the right looks to be for a small two-ended open-end wrench.

P.S. There is also a little emergency sunroof closure allen wrench that fits in the grove next to and below the screwdriver blade.


BMW has bee cost-reducing the X5, taking things out, such as the cargo cover lift cylinder, tools, stereo speakers, etc.
