Operation Check

1. If the cause of a symptom is any of the following, the corresponding symptom is normal, it is not a malfunction.
   SYMPTOM CHART
   
   

   Symptom	Answer
   A longer route than expected is chosen.	Depending on the road conditions, the navigation receiver assembly may determine that a longer route is quicker.
   Even when distance priority is high, the shortest route is not shown.	Some paths may not be advised due to safety concerns.
   When the vehicle is put into motion immediately after the engine starts, the navigation system deviates from the actual position.	If the vehicle starts before the navigation system activates, the system may not react.
   When running on certain types of roads, especially new roads, the vehicle position deviates from the actual position.	When the vehicle is driving on new roads not available on the map disc, the system attempts to match it to another nearby road, causing the position mark to deviate.

2. The following symptoms are not a malfunction, but are caused by errors inherent in the GPS, gyro sensor, speed sensor, or navigation receiver assembly.
   1. The current position mark may be displayed on a nearby parallel road.
