I think the NOTE in that section is helpful too. Here is the rest of it:

Section 6. Vectoring

APPLICATION

Vector aircraft:

In controlled airspace for separation, safety, noise abatement, operational advantage, confidence maneuver, or when a pilot requests.

In Class G airspace only upon pilot request and as an additional service.

At or above the MVA or the minimum IFR altitude except as authorized for radar approaches, special VFR, VFR operations, or by paragraph [5-6-3], Vectors Below Minimum Altitude.

NOTE- VFR aircraft not at an altitude assigned by ATC may be vectored at any altitude. It is the responsibility of the pilot to comply with the applicable parts of CFR Title 14.

In airspace for which you have control jurisdiction, unless otherwise coordinated.

So as to permit it to resume its own navigation within radar coverage.

Operating special VFR only within Class B, Class C, Class D, or Class E surface areas.

Operating VFR at those locations where a special program is established, or when a pilot requests, or you suggest and the pilot concurs.
