Wheel Securing Bolts

protection, a wrench socket with the appropriate
coding must be used between the wheel bolt and
the wheel-bolt spanner.
f When positioning the wrench socket, ensure
that it engages fully in the teeth of the wheel
bolt.
If the wheels have to be removed at the workshop,
please do not forget to hand over the wrench
socket for the wheel securing bolts along with the
car key.
