NAVIGATION SYSTEM (for DVD) SYSTEM NORMAL CONDITION CHECK

CHECK 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 receiver 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 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 malfunctions, 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.

   2. 

      Immediately after a fork in the road, the current vehicle position mark may be displayed on the wrong road.

   3. 

      When the vehicle turns right or left at an intersection, the current vehicle position mark may be displayed on a nearby parallel road.

   4. 

      When the vehicle is carried, such as on a ferry, and the vehicle itself is not running, the current vehicle position mark may be displayed in the position where the vehicle was until a measurement can be performed by GPS.

   5. 

      When the vehicle travels on a steep hill, the current vehicle position mark may deviate from the correct position.

   6. 

      When the vehicle makes a continuous turn (e.g. 360, 720, 1080. degrees) the current vehicle position mark may deviate from the correct position.

   7. 

      When the vehicle moves erratically, such as constant lane changes, the current vehicle position mark may deviate from the correct position.

   8. 

      When the ignition switch is turned on (ACC or IG) on a turntable before parking, the current vehicle position mark may not indicate the correct direction. The same will occur when the vehicle comes out of parking.

   9. 

      When the vehicle travels on a snowy road or a mountain path with the chains installed or using a spare tire, the current vehicle position mark may deviate from the correct position.

   10. 

       When a tire is changed, the current vehicle position mark may deviate from the correct position.

       Tip:
       

       • A change in tire diameter may cause a speed sensor error.

       • Performing "tire change" in calibration mode will allow the system to correct the current vehicle position faster.
