Navigation System Operation Check

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

The following symptoms are not malfunctions, but are caused by errors inherent in the GPS, gyro sensor, speed sensor or multi-media module 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 being driven, the current vehicle position mark may be displayed in the position where the vehicle was until a measurement can be performed by the 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 engine 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 the parking garage.
   





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





10. When the tires are changed, the current vehicle position mark may deviate from the correct position.
    

    HINT:

    1. A change in tire diameter may cause a speed sensor error.
       
    2. Performing "tire change" in calibration mode will allow the system to correct the current vehicle position faster.
