KAP 140 autopilot approach

I'm trying to figure out the right way to use the AP for an ILS. The
manual isn't clear on this situation. Assume that I have a vector to
intercept the localizer and have been cleared for the approach. Let's
say that the intercept angle is less than 45 degrees.

I'm starting in HDG & ALT hold modes.

Can I just press APR to get it to intercept the localizer? Or do I
need to press HDG to get into ROL mode first (because the intercept
angle isn't 45 degrees), then press APR?

Get in ROL mode, set the heading bug to the localizer course, then
press APR.

The above is only correct if you're using a DG; it is incorrect if you
have an HSI! If you set the heading bug to the localizer course, you
will never intercept the localizer.
Assuming you have an HSI and you are in HDG and ALT mode, you have set
the (yellow) localizer front course on the HSI. Now all you have to do
is press APR at which time the APR ARM indication lights up. You can
set the (orange) heading bug to any intercepting course you want.
