CHECK SYSTEM NORMAL CONDITION

  1. If the symptom is applicable to any of the following, it is intended behavior, and not a malfunction.

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