Capture will not occur if the preselected altitude is slewed through current altitude. At capture, the previously active vertical mode is cleared.
If the preselect altitude is changed, or if the VS pitch wheel is rotated during altitude capture, the autopilot or flight director continues to capture the original preselected altitude.
If a new preselect altitude is not set, then selection of IAS, MACH, PTCH or VS mode, will result in the current altitude being captured.

After capturing preselected altitude (altitude track), if preselect altitude is changed, altitude hold is automatically selected and altitude preselect rearmed.
Pushing in the ALT knob will cancel aural and visual alerts associated with the preselected altitude.
Altitude preselect mode is automatically selected upon selection of any vertical mode, except glideslope capture or overspeed. Altitude preselect mode is cleared by glideslope capture or overspeed.
Altitude preselect is annunciated on the PFD with a white ALTS message in the vertical arm field for arm; a green ALTS CAP message in the vertical capture field for capture, and a green ALTS message in the vertical capture field for track. Altitude captures, which are cleared without a subsequent selection of altitude track or arm, are annunciated with a yellow ALTS message on the PFD, which will remain for 10 seconds, or until altitude preselect is rearmed, whichever is shorter.
(4) Altitude HoldMode
Altitude hold mode generates commands to capture and maintain the altitude reference. When altitude hold mode is selected, the altitude reference is set to the current pressure altitude.
When altitude hold mode is selected by the flight management system, the altitude reference is a barometric value from the VNAV, which is converted to pressure altitude upon completion of capture.
The altitude reference is reset to current pressure altitude by selection of synchronization. There is no display of altitude reference value.
Altitude hold mode is selected by pushing the ALT switch on the flight control panel, or by changing the altitude preselect setting while in altitude preselected track. In VNAV mode, altitude hold can be selected by the flight management system. Selection is inhibited when in glideslope capture or overspeed.
Altitude hold mode is cleared by pushing the ALT switch again, by selection of a vertical hold mode, or by vertical mode capture.
Altitude hold mode is annunciated with a green ALT message in the vertical capturefield on theprimary flight display.
(5) SpeedMode(CLB,DES,IAS)
Speed mode generates commands to maintain the airspeed reference value. When speed mode is selected, the IAS reference (primary flight display) is set to the current airspeed.
