TAWS uses yellow (caution) and red (warning) to depict terrain and obstacles with heights greater than 200 feet above ground level, AGL. Alerts are given relative to aircraft altitude. Colors are adjusted automatically as the aircraft altitude changes. The colors and symbols shown in the figure and table below are used to represent terrain, obstacles, and potential impact points.

Table 6-5 TAWS Obstacle Colors and Symbology
TAWS information can be displayed on the following maps:
• PFD Inset Map• Navigation Map Page• TAWS Page• Trip Planning Page• Flight Plan Pages
Displaying terrain and obstacle information (maps other than the TAWS Page):
1) Select the MAP Softkey (for the PFD Inset Map, select the INSET Softkey).
2) Select the TERRAIN Softkey to display terrain and obstacle data.
When TAWS is selected on maps other than the TAWS Page, an icon to indicate the feature is enabled for display and a legend for TAWS terrain colors is shown.
The Navigation Map Page Setup Menu provides a means in addition to the softkey for enabling/disabling display of terrain and obstacles. The setup menu also controls the map range settings above which terrain and obstacle data are decluttered from the display. If a map range larger than the map range setting is selected, the data is removed from the map.

Terrain data can be selected for display independently of obstacle data; however, obstacles for which warnings and cautions are issued are shown when terrain is selected for display and the map range is within the setting limit.
Maps other than the TAWS Page use settings based on those selected for the Navigation Map Page. The maximum display ranges for obstacles on each map are dependent on the range setting made for the Navigation Map. If the maximum range for obstacle display on the Navigation Map is adjusted to below 20 nm, the highest obstacle display range settings on the other applicable maps are also adjusted proportionally.
Customizing terrain and obstacle display on the Navigation Map Page:
1) Select the Navigation Map Page.
2) Press the MENU Key.
3) With Map Setup highlighted, press the ENT Key (Figure 6-57).
4) Turn the small FMS Knob to select the Map Group and press the ENT Key (Figure 6-58).
5) Turn the large FMS Knob or press the ENT Key to scroll through product selections (Figure 6-59).
• TERRAIN DATA – Turns the display of terrain data on or off and sets maximum range at which terrain is shown
• OBSTACLE DATA – Turns the display of obstacle data on or off and sets maximum range at which obstacles are shown
6) Turn the small FMS Knob to scroll through options for each product (ON/OFF, range settings).
7) Press the ENT Key to select an option.
8) Press the FMS Knob or CLR Key to return to the Navigation Map Page with the changed settings.

TAWS Pageage
The TAWS Page is specialized to show terrain, obstacle, and potential impact point data in relation to the aircraft’s current altitude, without clutter from the basemap. Aviation data (airports, VORs, and other NAVAIDs) can be displayed for reference. If an obstacle and the projected flight path of the aircraft intersect, the display automatically zooms in to the closest potential point of impact on the TAWS Page.
