necessary specialist knowledge and tools
to carry out the work required. Mercedes-
Benz recommends that you use a

designed for the wheel and the vehicle. For
safety reasons, Mercedes-Benz recom- mends that you only use wheel bolts which
have been approved for Mercedes-Benz
vehicles. Other bolts could work loose.
