  • Page 6 Warnings, Cautions & Notes WARNING: Navigation and terrain separation must NOT be predicated upon the use of the terrain function. The G3X Terrain Proximity feature is NOT intended to be used as a primary reference for terrain avoidance and does not relieve the pilot from the responsibility of being aware of surroundings during flight.
  • Page 7 System and is solely responsible for its accuracy and maintenance. The GPS system is subject to changes which could affect the accuracy and performance of all GPS equipment. Portions of the Garmin G3X utilize GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as with all NAVAIDs, informa- tion presented by the G3X can be misused or misinterpreted and, therefore, become unsafe.
  • Page 8 WARNING: Do not use the approach information provided by the VFR navigation database residing within the G3X as a means of navigating any instrument approach. The G3X VFR navigation database is limited to pres- ent only the waypoints for the final approach leg of a published procedure.
  • Page 9 Although unlikely, it may be possible for erroneous operation to occur without a fault indication shown by the G3X. It is thus the responsibility of the pilot to detect such an occurrence by means of cross-checking with all redundant or correlated information available in the cockpit.
