3) Press the APR Key.
Or:
1) Ensure that GPS is the selected navigation source (use the CDI Softkey to cycle through navigation sources if necessary).

3) Ensure the corresponding LOC frequency is tuned.
4) Press the APR Key.

Once LOC is the navigation source, the localizer and glideslope can be captured. Upon reaching the glideslope, the flight director transitions to Glideslope Mode and begins to capture and track the glideslope.

Takeoff (TO) and Go Around (GA) Modes
Go Around and Takeoff modes are coupled pitch and roll modes and are annunciated as both the vertical and lateral modes when active. In these modes, the flight director commands a constant set pitch attitude and keeps the wings level. The GA Switch is used to select both modes. The mode entered by the flight director depends on whether the aircraft is on the ground.
Takeoff Mode provides an attitude reference during rotation and takeoff. This mode can be selected only while on the ground by pushing the GA Switch. The flight director Command Bars assume a wings-level, pitch-up attitude.
Pressing the GA Switch while in the air activates the flight director in a wings-level, pitch-up attitude, allowing the execution of a missed approach or a go around. Go Around Mode disengages the autopilot and arms Selected Altitude Capture Mode automatically. Subsequent autopilot engagement is allowed. Attempts to modify the aircraft attitude (i.e., with the NOSE UP/DN Wheel or CWS Button) result in reversion to Pitch and Roll Hold modes.
