NAVIGATION SYSTEM (for HDD)

PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL

Note

After the power switch is turned off, the navigation computer sub-assembly (HDD navigation system) records various types of memory and settings. As a result, after turning the power switch off, make sure to wait for the time specified in the following table before disconnecting the cable from the negative (-) auxiliary battery terminal.

Waiting Time before Disconnecting Cable from Negative (-) Auxiliary Battery Terminal
Specification	Waiting Time
w/o Telematics transceiver	60 sec.
w/ Telematics transceiver	120 sec.

When disconnecting the cable from the negative (-) auxiliary battery terminal, initialize the following systems after the cable is reconnected.

PRECAUTIONS FOR G-BOOK (w/ G-BOOK System)

The navigation computer sub-assembly functions as the G-BOOK device, it also holds the G-BOOK ID.

Note

When replacing the navigation computer sub-assembly, perform vehicle contract setting Click here.
Necessary data for the G-BOOK system is stored in the HDD that is built into the navigation computer sub-assembly.

PRECAUTIONS FOR NAVIGATION COMPUTER SUB-ASSEMBLY

An HDD is built into the navigation computer sub-assembly to store map and other data, and is used for the navigation system. Therefore, care must be taken for the following points when handling:
1. When it is necessary to replace the navigation computer sub-assembly, be sure to replace it with a new one.
  
  Note
  
  If a used navigation computer sub-assembly is installed as a replacement part, the customer's HDD will not be recognized.
2. Do not apply any vibration or shock to the navigation computer sub-assembly.
  Note
  - Do not drop or subject the navigation computer sub-assembly to severe impacts.
  - Do not use the navigation computer sub-assembly if it has been dropped or subjected to a severe impact.
  - Do not store the navigation computer sub-assembly without the HDD installed. (Only remove the HDD from the navigation computer sub-assembly when the replacement navigation computer sub-assembly or HDD is ready.)
3. Do not remove the navigation computer sub-assembly if there is a risk that condensation may occur.
  
  Note
  
  If the temperature of the navigation computer sub-assembly changes rapidly, condensation may occur inside the unit. This may cause a malfunction of the HDD. Therefore, when the navigation computer sub-assembly is removed from the instrument panel, it needs to be kept inside the vehicle or in an environment with an equivalent temperature and humidity.
4. Take measures to prevent static electricity.
  
  Note
  
  Touching the terminals of a connector can cause static electricity to be transmitted to the internal circuits. This may cause a malfunction of the HDD.
5. Keep the navigation computer sub-assembly away from magnets or magnetized items.
  
  Note
  
  Keep the navigation computer sub-assembly away from speakers, motors, magnetized tools and other magnetic items.

PRECAUTIONS FOR HARD DISK DRIVE (HDD)

Map and other data for the navigation system is stored on the Hard Disk Drive (HDD). Make sure to follow the following instructions when replacing the HDD:
1. The HDD must only be replaced with a new one. Do not attempt to install a used HDD from another vehicle.
  
  Note
  
  The navigation computer sub-assembly can recognize only a new HDD.
2. Do not touch the HDD cover.
  
  Note
  
  When removing or installing the HDD, only hold it by the areas shown in the illustration.
3. Do not apply any vibration or shock to the HDD.
  Note
  - Do not drop or subject the HDD to sever impacts.
  - Do not use the HDD if it has been dropped or subjected to a sever impact.
  - Do not store the HDD by itself if it has been removed from the navigation computer sub-assembly. (Only remove the HDD from the navigation computer sub-assembly when the replacement navigation computer sub-assembly or HDD is ready.)
4. Do not remove the HDD if there is a risk that condensation may occur.
  
  Note
  
  If the temperature of the HDD changes rapidly, condensation may occur inside the unit. This may cause a malfunction of the HDD. Therefore, when the navigation computer sub-assembly is removed from the instrument panel, it needs to be kept inside the vehicle or in an environment with an equivalent temperature and humidity.
5. Take measures to prevent static electricity.
  
  Note
  
  Touching the terminals of a connector can cause static electricity to be transmitted to the internal circuits. This may cause a malfunction of the HDD.
6. Keep the HDD away from magnets or magnetized items.
  
  Note
  
  Keep the HDD away from speakers, motors, magnetized tools and other magnetic items.
7. Inspect after HDD replacement.
  
  Note
  
  Make sure to perform Check Hard Disk Drive in Operation Check to confirm that there are no HDD abnormalities after removal or installation Click here.

PRECAUTIONS FOR CENTER INSTRUMENT CLUSTER FINISH PANEL ASSEMBLY

Note

The center instrument cluster finish panel assembly has driving parts that drive the multi-display. Depending on the condition of the driving parts, the multi-display may not open, close or tilt properly. Therefore, make sure to follow the notices below when disassembling and assembling the center instrument cluster finish panel assembly.

When disassembling the center instrument cluster finish panel assembly, remove it without damaging the driving parts or catching foreign objects, and store it.
When assembling the center instrument cluster finish panel assembly, install it without damaging the driving parts or catching foreign objects.
