Caution!
Risk of damage due to scratches.
f Be careful when removing the wheel-hub cap.
4. Carefully lever out the wheel-hub cap using a
small screwdriver.
To do this, insert the screwdriver in groove A.
Apply a piece of adhesive tape to the
screwdriver if necessary to avoid scratching
the surface of the bolt.
f The central bolt must always be opened using
the original tool (stored in the luggage
compartment).
f Always keep the wrench socket in the luggage
compartment so that it is available in the event
of a breakdown.
5. Insert the socket and fit it as far as it
will go. This pushes back the safety lock
in the central bolt.
Note
The socket locks in this position.
A very high torque is required to loosen the
central bolt.
f Turn in the correct direction!
f Prevent the wheel from turning by getting a
second person to brake using the brake pedal.
Warning!
Risk of damage to the safety lock.
f When loosening the central bolt, make sure
that the tool remains fully inserted and
cannot slide off.
