1. Insert the key into the handwheel
and turn it clockwise to unlock.
2. Pull the handwheel out and turn it
anti-clockwise to the stop. The
tow ball arm automatically swivels
into the midway position.
3. Release the handwheel. The tow
ball arm is not locked. This is
indicated by the warning tone and
the handwheel projects about five
millimetres (0.2 inch) from its
housing.
4. Manually turn the tow ball arm
steadily from its midway position
to the stop in the operating
position. The tow ball arm
automatically locks in the end
position. The locking process is
clearly audible if the level of
background noise is not too high.
When the locking process is
completed, the warning tone
stops and the handwheel will
return to its original position.
5. Turn the key anti-clockwise and
remove it. Insert the key into the
storage position.
